The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel.

A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.
A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.
An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
An alkaloid, originally from Atropa belladonna, but found in other plants, mainly SOLANACEAE. Hyoscyamine is the 3(S)-endo isomer of atropine.
Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

Effect of riluzole on the neurological and neuropathological changes in an animal model of cardiac arrest-induced movement disorder. (1/1834)

Posthypoxic myoclonus and seizures precipitate as secondary neurological consequences in ischemic/hypoxic insults of the central nervous system. Neuronal hyperexcitation may be due to excessive activation of glutamatergic neurotransmission, an effect that has been shown to follow ischemic/hypoxic events. Therefore, riluzole, an anticonvulsant that inhibits the release of glutamate by stabilizing the inactivated state of activated voltage-sensitive sodium channels, was tested for its antimyoclonic and neuroprotective properties in the cardiac arrest-induced animal model of posthypoxic myoclonus. Riluzole (4-12 mg/kg i.p.) dose-dependently attenuated the audiogenic seizures and action myoclonus seen in this animal model. Histological examination using Nissl staining and the novel Fluoro-Jade histochemistry in cardiac-arrested animals showed an extensive neuronal degeneration in the hippocampus and cerebellum. Riluzole treatment almost completely prevented the neuronal degeneration in these brain areas. The neuroprotective effect was more pronounced in hippocampal pyramidal neurons and cerebellar Purkinje cells. These effects were seen at therapeutically relevant doses of riluzole, and the animals tolerated the treatment well. These findings indicate that the pathogenesis of posthypoxic myoclonus and seizure may involve excessive activation of glutamate neurotransmission, and that riluzole may serve as an effective pharmacological agent with neuroprotective potential for the treatment of neurological conditions associated with cardiac arrest in humans.  (+info)

Fibrinolytic activation markers predict myocardial infarction in the elderly. The Cardiovascular Health Study. (2/1834)

Coagulation factor levels predict arterial thrombosis in epidemiological studies, but studies of older persons are needed. We studied 3 plasma antigenic markers of fibrinolysis, viz, plasminogen activator inhibitor-1 (PAI-1), fibrin fragment D-dimer, and plasmin-antiplasmin complex (PAP) for the prediction of arterial thrombosis in healthy elderly persons over age 65. The study was a nested case-control study in the Cardiovascular Health Study cohort of 5201 men and women >/=65 years of age who were enrolled from 1989 to 1990. Cases were 146 participants without baseline clinical vascular disease who developed myocardial infarction, angina, or coronary death during a follow-up of 2.4 years. Controls remained free of cardiovascular events and were matched 1:1 to cases with respect to sex, duration of follow-up, and baseline subclinical vascular disease status. With increasing quartile of D-dimer and PAP levels but not of PAI-1, there was an independent increased risk of myocardial infarction or coronary death, but not of angina. The relative risk for D-dimer above versus below the median value (>/=120 microg/L) was 2.5 (95% confidence interval, 1.1 to 5.9) and for PAP above the median (>/=5.25 nmol/L), 3.1 (1.3 to 7.7). Risks were independent of C-reactive protein and fibrinogen concentrations. There were no differences in risk by sex or presence of baseline subclinical disease. D-dimer and PAP, but not PAI-1, predicted future myocardial infarction in men and women over age 65. Relationships were independent of other risk factors, including inflammation markers. Results indicate a major role for these markers in identifying a high risk of arterial disease in this age group.  (+info)

Repeated administration of vasopressin but not epinephrine maintains coronary perfusion pressure after early and late administration during prolonged cardiopulmonary resuscitation in pigs. (3/1834)

BACKGROUND: It is unknown whether repeated dosages of vasopressin or epinephrine given early or late during basic life support cardiopulmonary resuscitation (CPR) may be able to increase coronary perfusion pressure above a threshold between 20 and 30 mm Hg that renders defibrillation successful. METHODS AND RESULTS: After 4 minutes of cardiac arrest, followed by 3 minutes of basic life support CPR, 12 animals were randomly assigned to receive, every 5 minutes, either vasopressin (early vasopressin: 0.4, 0.4, and 0.8 U/kg, respectively; n=6) or epinephrine (early epinephrine: 45, 45, and 200 microg/kg, respectively; n=6). Another 12 animals were randomly allocated after 4 minutes of cardiac arrest, followed by 8 minutes of basic life support CPR, to receive, every 5 minutes, either vasopressin (late vasopressin: 0.4 and 0.8 U/kg, respectively; n=6), or epinephrine (late epinephrine: 45 and 200 microg/kg, respectively; n=6). Defibrillation was attempted after 22 minutes of cardiac arrest. Mean+/-SEM coronary perfusion pressure was significantly higher 90 seconds after early vasopressin compared with early epinephrine (50+/-4 versus 34+/-3 mm Hg, P<0.02; 42+/-5 versus 15+/-3 mm Hg, P<0.0008; and 37+/-5 versus 11+/-3 mm Hg, P<0. 002, respectively). Mean+/-SEM coronary perfusion pressure was significantly higher 90 seconds after late vasopressin compared with late epinephrine (40+/-3 versus 22+/-4 mm Hg, P<0.004, and 32+/-4 versus 15+/-4 mm Hg, P<0.01, respectively). All vasopressin animals survived 60 minutes, whereas no epinephrine pig had return of spontaneous circulation (P<0.05). CONCLUSIONS: Repeated administration of vasopressin but only the first epinephrine dose given early and late during basic life support CPR maintained coronary perfusion pressure above the threshold that is needed for successful defibrillation.  (+info)

Frequency of arrhythmias and other cardiac abnormalities in fulminant hepatic failure. (4/1834)

In a series of 106 patients with fulminant hepatic failure and grade 4 encephalopathy, cardiac arrhythmias and other abnormalities occurred in 92 per cent. The most common was sinus tachycardia (75%) and this was the only abnormality in 22 per cent of the patients. Sudden cardiac arrest occurred in 25 per cent, various ectopic beats in 20 per cent, and heart block or bradycardia in 18 per cent. Other electrocardiographic abnormalities, mostly of the T wave and ST segment, were found in 31 per cent. Cardiac and respiratory arrests were usually unrelated to each other and both frequently occurred without warning. Only 7 out of 71 patients with arrhythmias other than sinus tachycardia survived, compared with 15 out of 31 patients without them (P less than 0-005). During the latter part of the series when an arrhythmia computer was used to monitor 38 patients, it was shown that significantly lower arterial oxygen levels occurred in those with arrhythmias, other than sinus tachycardia, than in those without. They were also found to be more acidotic and hyperkalaemic, and a higher number required dialysis and ventilation. Macroscopical cardiac abnormalities including scattered petechial haemorrhages, small pericardial effusions, and fatty, pale, and flabby ventricles, were found at necropsy in 64 per cent of the patients examined. Combinations of these macroscopical abnormalities occurred, particularly in the paracetamol overdose group. Another necropsy finding of possible significance in the pathogenesis of arrhythmias was cerebral oedema, present in 48 per cent of the patients examined, and often associated with coning of the brain stem. However, 7 of the 16 patients who suffered asystolic cardiac arrests had no macroscopical abnormality of either heart or brain. In the management of patients with fulminant hepatic failure continuous cardiac monitoring is essential. Correction of the biochemical and coagulation defects may decrease the frequency of arrhythmias but studies of the mechanism and control of cerebral oedema and its relation to cardiovascular function are urgently needed.  (+info)

Bilateral vertebral artery occlusion following cervical spine trauma--case report. (5/1834)

A 41-year-old female presented with a rare case of bilateral vertebral artery occlusion following C5-6 cervical spine subluxation after a fall of 30 feet. Digital subtraction angiography showed occlusion of the bilateral vertebral arteries. Unlocking of the facet joint, posterior wiring with iliac crest grafting, and anterior fusion were performed. The patient died on the 3rd day after the operation. This type of injury has a grim prognosis with less than a third of the patients achieving a good outcome.  (+info)

Resuscitation from out-of-hospital cardiac arrest: is survival dependent on who is available at the scene? (6/1834)

OBJECTIVE: To determine whether survival from out-of-hospital cardiac arrest is influenced by the on-scene availability of different grades of ambulance personnel and other health professionals. DESIGN: Population based, retrospective, observational study. SETTING: County of Nottinghamshire with a population of one million. SUBJECTS: All 2094 patients who had resuscitation attempted by Nottinghamshire Ambulance Service crew from 1991 to 1994; study of 1547 patients whose arrest were of cardiac aetiology. MAIN OUTCOME MEASURES: Survival to hospital admission and survival to hospital discharge. RESULTS: Overall survival from out-of-hospital cardiac arrest remains poor: 221 patients (14.3%) survived to reach hospital alive and only 94 (6.1%) survived to be discharged from hospital. Multivariate logistic regression analysis showed that the chances of those resuscitated by technician crew reaching hospital alive were poor but were greater when paramedic crew were either called to assist technicians or dealt with the arrest themselves (odds ratio 6.9 (95% confidence interval 3.92 to 26.61)). Compared to technician crew, survival to hospital discharge was only significantly improved with paramedic crew (3.55 (1.62 to 7.79)) and further improved when paramedics were assisted by either a health professional (9.91 (3.12 to 26.61)) or a medical practitioner (20.88 (6.72 to 64.94)). CONCLUSIONS: Survival from out-of-hospital cardiac arrest remains poor despite attendance at the scene of the arrest by ambulance crew and other health professionals. Patients resuscitated by a paramedic from out-of-hospital cardiac arrest caused by cardiac disease were more likely to survive to hospital discharge than when resuscitation was provided by an ambulance technician. Resuscitation by a paramedic assisted by a medical practitioner offers a patient the best chances of surviving the event.  (+info)

Delayed ischemic hyperintensity on T1-weighted MRI in the caudoputamen and cerebral cortex of humans after spectacular shrinking deficit. (7/1834)

BACKGROUND AND PURPOSE: Transient internal carotid artery (ICA)-middle cerebral artery (MCA) occlusion caused by cardiogenic embolus can lead to spectacular shrinking deficit (SSD): sudden hemispheric stroke syndrome followed by rapid improvement. The aim of this study was to investigate sequential neuroradiological changes in the brains of patients after SSD compared with those after brief cardiac arrest and hypoglycemia, which we previously studied with the same methods. METHODS: We serially studied CT scans and MR images obtained at 1.5 T in 4 patients with SSD. All 4 patients suffered from transient neurological deficits due to cardiogenic embolus in ICA-MCA. The symptoms began to disappear from 25 to 50 minutes after onset. RESULTS: Repeated CT scans demonstrated no abnormal findings in the affected cerebral hemisphere in 3 of the 4 patients and a small cortical infarct in the remaining 1. In each patient, repeated MRI between day 7 and month 23 after stroke showed basal ganglionic and cortical lesions. These lesions were hyperintense on T1-weighted and relatively hypointense on T2-weighted imaging. These ischemic lesions of hyperintensity on T1-weighted MRI subsided with time. CONCLUSIONS: Transient ICA-MCA occlusion leading to SSD produces a specific ischemic change with delayed onset in the basal ganglia and cerebral cortex in humans on MRI but not CT scans. We speculate that the lesions represent incomplete ischemic injury, including selective neuronal death, proliferation of glial cells, paramagnetic substance deposition, and/or lipid accumulation. Unlike brief cardiac arrest or hypoglycemia, the localized lesions on MRI of patients after SSD seem to be incomplete and to differ from infarction or hemorrhage.  (+info)

Dynamics of tissue oxygenation in isolated rabbit heart as measured with near-infrared spectroscopy. (8/1834)

We investigated the role of myoglobin (Mb) in supplying O2 to mitochondria during transitions in cardiac workload. Isovolumic rabbit hearts (n = 7) were perfused retrogradely with hemoglobin-free Tyrode solution at 37 degrees C. Coronary venous O2 tension was measured polarographically, and tissue oxygenation was measured with two-wavelength near-infrared spectroscopy (NIRS), both at a time resolution of approximately 2 s. During transitions to anoxia, 68 +/- 2% (SE) of the NIRS signal was due to Mb and the rest to cytochrome oxidase. For heart rate steps from 120 to 190 or 220 beats/min, the NIRS signal decreased significantly by 6.9 +/- 1.3 or 11.1 +/- 2.1% of the full scale, respectively, with response times of 11.0 +/- 0.8 or 9.1 +/- 0.5 s, respectively. The response time of end-capillary O2 concentration ([O2]), estimated from the venous [O2], was 8.6 +/- 0.8 s for 190 beats/min (P < 0.05 vs. NIRS time) or 8.5 +/- 0.9 s for 220 beats/min (P > 0.05). The mean response times of mitochondrial O2 consumption (VO2) were 3.7 +/- 0.7 and 3.6 +/- 0.6 s, respectively. The deoxygenation of oxymyoglobin (MbO2) accounted for only 12-13% of the total decrease in tissue O2, with the rest being physically dissolved O2. During 11% reductions in perfusion flow at 220 beats/min, Mb was 1.5 +/- 0.4% deoxygenated (P < 0.05), despite the high venous PO2 of 377 +/- 17 mmHg, indicating metabolism-perfusion mismatch. We conclude that the contribution of MbO2 to the increase of VO2 during heart rate steps in saline-perfused hearts was small and slow compared with that of physically dissolved O2.  (+info)

Objective- It is known that recovery from neurologic damage takes 6-12 months. However, most studies on out of hospital cardiac arrest (OHCA) use the Overall Performance Category (OPC)/Cerebral Performance Category (CPC) as outcome at discharge from hospital. We studied the neurocognitive functioning and level of independence (LoI) of patients (pts) 6-12 months after OHCA and compared the results with the OPC/CPC at discharge.. Materials and methods- The study population comprises all pts (,18 year) who survived 6-12 months after OHCA from mid-2010 to mid-2011. Pts were interviewed by telephone with questionnaires validated for telephonic application. We used a validated cut-off score. Neurocognitive functioning was measured with the Telephonic Interview Cognitive Status (TICS) and LoI with the Modified Rankin Scale (MRS). If needed, the IQ-code was used as proxy-questionnaire to measure the neurocognitive functioning of the pt. Neurological outcome at discharge was assessed from hospital ...
Methods and Results-Between 2000 and 2009, we identified children (,18 years of age) with an in-hospital cardiac arrest at hospitals with ,3 years of participation and ,5 cases annually within the national Get With The Guidelines-Resuscitation registry. Multivariable logistic regression was used to examine temporal trends in survival to discharge. We also explored whether trends in survival were attributable to improvement in acute resuscitation or postresuscitation care and examined trends in neurological disability among survivors. Among 1031 children at 12 hospitals, the initial cardiac arrest rhythm was asystole and pulseless electrical activity in 874 children (84.8%) and ventricular fibrillation and pulseless ventricular tachycardia in 157 children (15.2%), with an increase in cardiac arrests due to pulseless electrical activity over time (P for trend ,0.001). Risk-adjusted rates of survival to discharge increased from 14.3% in 2000 to 43.4% in 2009 (adjusted rate ratio per year, 1.08; 95% ...
Transthoracic cardiac stimulation therapies provide for detection and treatment of cardiac asystole subsequent to delivery of a defibrillation therapy. A pacing therapy is transthoracicly delivered to terminate detected cardiac asystole using residual energy from a defibrillation energy storage source. The residual energy usable for the pacing therapy is sufficient to transthoracicly deliver at least one pacing pulse, and is typically sufficient to deliver a series of pacing pulses, prior to depletion of the defibrillation energy storage source. Detection of cardiac asystole is performed following delivery of each pacing pulse, and subcutaneous pacing support is terminated in response to detecting cardiac asystole termination.

Lower survival rates are observed during nights and on weekends, except in areas with consistent physician care, such as the Emergency Department. Since 1997, our hospital has utilized a standard, hospital-wide Code Blue Team (CBT) to respond to cardiac arrests at any time. This team is always led by an emergency physician, and includes specially trained nurses. Objective: To assess if time of day or week affects survival from in-hospital cardiac arrest when a trained, consistent, emergency physician-led CBT is implemented. Methods: This is an analysis of prospectively collected data on initial survival rates (return of spontaneous circulation ...

As a result, targeted normothermic temperature management has become standard of ...
Our study showed that the percentage of patients surviving to discharge following cardiopulmonary arrest was higher in summer than winter. Although this difference was significant, the absolute difference in percentages was small. As a result prognosis remained poor even in summer.. A winter peak in CHD mortality has been shown in both northern and southern hemisphere countries.1-6 In England, this accounts for an additional 20 000 deaths per annum.11 Variations in myocardial infarction admissions and trial recruitment have been cited as evidence that this reflects a seasonal variation in CHD incidence.1 7 8 However, seasonal variations in mortality are greater than those in admission,2 suggesting that case fatality rates may also vary throughout the year. Enquselassie et al showed that CHD events were more likely to be fatal when the temperature was low.4 These findings are supported by the results of our study. The numbers of resuscitation attempts were comparable in summer and winter, but ...
275 patients seen in the emergency department, who were 18 to 75 years of age (median age 59 y, 76% men) and had spontaneous circulation restored after a witnessed cardiac arrest with ventricular fibrillation or nonperfusing ventricular tachycardia as the initial cardiac rhythm; a presumed cardiac origin of the arrest; an estimated interval of 5 to 15 minutes from the collapse to the first attempt at resuscitation by emergency medical personnel; and an interval of ≤ 60 minutes from collapse to restoration of spontaneous circulation. Exclusion criteria included a tympanic-membrane temperature , 30°C on admission and response to verbal commands before randomization. Follow-up was 99% for neurologic outcomes and 100% for mortality ...
In-hospital cardiac arrest carries a grave prognosis, with survival to discharge in the range of 15-20%. Key factors determining outcome include the presenting cardiac rhythm, aetiology, and early initiation of resuscitation. Some cardiac rhythms benefit from defibrillation (shockable rhythms). During resuscitation patients may switch between shockable and non-shockable rhythms, and may show signs of spontaneous circulation temporarily. Depending on rhythm and according to guidelines, patients receive direct current (DC) shocks (defibrillator) and/or i.v. adrenaline, atropine and amiodarone, which may affect state-transitions. We wish to make statistical analysis (time-series analysis, Markov modelling) of these state-transitions and variations in hemodynamic variables during resuscitation, related to CPR interventions and the cause of arrest. The cause of arrest will be determined based on chart records, interview with staff and autopsy if appropriate. One hypothesis is that differences in the ...
Our study has the advantage that it includes all out of hospital cardiac arrests caused by coronary heart disease in the age group studied over a period of nearly two million person years of observation, with necropsy verification in 86% of those who died. Our study needs to be distinguished from those that included only cases in which resuscitation had been attempted or that included arrests not caused by coronary heart disease.8,9,10,11 A limitation of the study is that people aged 76 years or older, an increasing proportion of patients, were excluded. Contemporary data from UK hospitals as recorded by the Myocardial Infarction National Audit Project (MINAP) show that nearly one third of hospital patients with acute myocardial infarction and one quarter of survivors of arrest in hospital are now over 75 years old.14) Similar figures for arrests occurring outside hospital in busy public places are provided by the UK government led programme for rapid access defibrillation.6,7 In nearly 700 ...

We aimed to give an overview of the management and outcome of elderly patients after successful CPR and post-resuscitation therapy in our retrospective cohort study and systemic literature review.. There are several questions, challenges and ethical dilemmas in the post-cardiac arrest treatment of the aging population. Data from previously published studies demonstrate the association between age and outcome in this patient group [5-13]. However, this relationship is influenced by various factors and therefore expose many questions regarding the nature of this finding.. We could not show any association between age, 30-day or 1-year survival and neurologic outcome at discharge among patients treated after ROSC at our ICU. This finding fully contradicts formerly published data. All papers included in our literature review found a decrease in survival with increasing age, and four of them reported advanced age as one of the independent predictors of mortality [16-22]. On the other hand, the ...

A large family describes episodes in affected individuals of excruciating rectal pain, flushing of the buttocks and legs, ocular pain, flushing of the eyelids, and periorbital skin, and submaxillary pain. Tonic atacks with bradycardia in infancy and apnea and cardiac asystole with these tonic nonepileptic seizures may be part of the syndrome. The onset may even be in utero. Newborns may be stiff and red. The precipitant for the first attack is usually defecation. Other triggers might include bathing, sudden loud noises, feeding and perineal toilet, cold , wind, eating and emotion. Painful attacks can be divided into rectal, ocular and jaw. However, pain is not restricted to these sites. Flushing is a constant feature and accompanies pain in younger individuals. The pain starts as an itch like pain then burning lancinate, stabbing, and becomes unbearable, the worst pain imaginable. Flushes may be geographic but not always. Harlequin color changes are common but not universal and may affect half ...

Advanced Cardiac Life Support (ACLS) is a course developed by the American Heart Association for the training of health care providers. It emphasizes the knowledge and skills necessary to provide the appropriate early treatment for cardiopulmonary arrest. Additional important areas of emphasis include the proper management of situations likely to lead to cardiac arrest and the stabilization of the patient in the early period following a successful resuscitation. ACLS includes, the use of adjunctive equipment and special techniques for establishing and maintaining effective ventilation and circulation. In addition, this program teaches how to treat the patient with suspected acute myocardial infarction and stroke. Upon successful completion, participants will be granted an ACLS provider card through the American Heart Association. Provider status is valid for two years, and a renewal course is required to remain an ACLS provider.. ...
The Advanced Cardiac Life Support (ACLS) New Provider Course is designed for healthcare providers who either direct or participate in the management of cardiopulmonary arrest or other cardiovascular emergencies (ACLS Instructor Manual, 2015). The ACLS course is taught over 2 days. You must have a current BLS Provider Card to take this course.

BACKGROUND: While internationally reported survival from out-of-hospital cardiac arrest (OHCA) is improving, much of the increase is being observed in patients presenting to emergency medical services (EMS) in shockable rhythms. The purpose of this study was to assess survival and 12-month functional recovery in patients presenting to EMS in asystole or pulseless electrical activity (PEA).. METHODS: The Victorian Ambulance Cardiac Arrest Registry was searched for adult OHCA patients presenting in non-shockable rhythms in Victoria, Australia between 1st July 2003 and 30th June 2013. We excluded patients defibrillated prior to EMS arrival and arrests witnessed by EMS. Twelve-month quality-of-life interviews were conducted on survivors who arrested between 1st January 2010 and 31st December 2012. The main outcome measures were survival to hospital discharge and 12-month functional recovery measured by the Extended Glasgow Outcome Scale (GOSE).. RESULTS: A total of 38,378 non-shockable OHCA attended ...
The survival to discharge rate after unwitnessed, non-cardiac out-of-hospital cardiac arrest (OHCA) is dismal. We report the successful use of therapeutic hypothermia in a 26-year old woman with OHCA due to intentional poisoning with heroin, amphetamine and insulin. The cardiac arrest was not witnessed, no bystander CPR was initiated, the time interval from the call to ambulance arrival was 9 minutes and the initial cardiac rhythm was asystole. Eight minutes of advanced cardiac life support resulted in ROSC. Upon hospital admission, the patients pupils were dilated. Her arterial lactate was 17 mmol/l, base excess -20, pH 6.9 and serum glucose 0.2 mmol/l. During the first 24 hours in the ICU, the patient developed maximally dilated pupils not reacting to light and became increasingly haemodynamically unstable, requiring both inotropic support and massive fluid resuscitation. After 1 week in the ICU, however, she made an uneventful recovery with a Cerebral Performance Category of 1 at hospital discharge

Resuscitation after cardiac arrest (CA) in the catheterization laboratory (cath-lab) using mechanical chest compressions (CC) during simultaneous percutaneous coronary intervention (PCI) is a strong recommendation in the 2015 European Resuscitation Council (ERC) guidelines. This study aimed at re-evaluating survival to hospital discharge and assess long term outcome in this patient population. Patients presenting at the cath lab with spontaneous circulation, suffering CA and requiring prolonged mechanical CC during cath lab procedures between 2009 and 2013 were included. Circumstances leading to CA, resuscitation parameters and outcomes were evaluated within this cohort. For comparison, patients needing prolonged manual CC in the cath lab in the pre-mechanical CC era were evaluated. Six-month and one year survival with a mechanical CC treatment strategy from 2004 to 2013 was also evaluated. Thirty-two patients were included between 2009 and 2013 (24 ST-elevation myocardial infarction (STEMI), 4 non

N2 - To compare the effectiveness of manual and mechanical chest compression during cardiopulmonary resuscitation, 50 patients who suffered cardiac arrest were randomly allocated to receive manual or mechanical chest compression. Randomization was performed after failure of initial resuscitative measures but within ten minutes after the onset of cardiac arrest (mean, 6.4 ±1.2 min). Ten patients from each group survived longer than one hour following resuscitation. Three from the mechanical group and two from the manual group were eventually able to leave the hospital. Thus mechanical compression appears comparable with manual compression when manual compression is performed under ideal conditions. Mechanical chest ...
Introduction: In-hospital cardiac arrests (IHCAs) result in the premature death of ,300K patients annually in the US. IHCA survival rates average 17% and provide an indicator of in-hospital quality of care. Since 2006 outcomes after IHCA were tracked after implementation of the 2005 AHA Guidelines with the exception of therapeutic hypothermia. The IHCA care initiatives, termed high-performance (HP) CPR, included focus on compressions and use of the impedance threshold device (ITD). The ITD (ResQPOD®) increases circulation during HP-CPR by regulating intrathoracic pressure. In an effort to improve outcomes from IHCA, we compared our 5 year experience before and after HP-CPR.. Methods: The study was performed at St. Dominic Hospital in Jackson, Mississippi. Hospital discharge (HD) rates were compared before and after HP-CPR from 681 ICHA patients over five years, using Fishers exact test, odds ratio (OR) and 95% confidence intervals (CI). Only the first IHCA occurring on the wards or in ICU were ...

A basic life support working group of the European Resuscitation Council was set up in 1991. It was given the objective of producing agreed standards of basic life support to ensure uniform teaching of the techniques to health care professionals and lay people throughout Europe. A common complaint in the past, particularly from members of the public who have received instruction in basic life support, is that different organisations teach different techniques. This problem exists within countries as well as among countries. The European Resuscitation Council presents below its basic life support guidelines, which it hopes will be detailed enough to avoid any ambiguities and to be acceptable for use in all the countries represented by the council. ...

Given improvement in test scores, we advocate for and support the AHA decision to incorporate FC and TBL techniques in the educational program for the 2015 ACLS guidelines. Evaluation methods for mastery of ACLS course, per the AHA include both content (written) and performance assessments. Successful students must demonstrate team leadership and psychomotor skills in managing cardiac arrest and peri-arrest scenarios. Though evidence for content and construct validity for the written portion of ACLS assessment is largely lacking, and some evidence is to the contrary, both written and performance assessments have been shown to correlate moderately. A previous study advocated for dual evaluation methods as complementary, demonstrating different psychomotor and cognitive skills [8,9]. Given delivery of similar content in our course, improvements in test scores indicate further mastery of the required material. In the highest-stakes environment of cardiac arrest, demonstration of mastery at an ...

Non-occlusive colonic ischaemia is a recognized albeit rare entity related to low blood flow within the visceral circulation and in most reported cases the right colon was affected. This is the second case report in the literature of extensive colonic necrosis following cardiac arrest and cardiopulmonary resuscitation (CPR). A 83-year-old Caucasian woman was admitted to our hospital due to a low energy hip fracture. On her way to the radiology department she sustained a cardiac arrest. CPR started immediately and was successful. A few hours later, the patient developed increasing abdominal distension and severe metabolic acidocis. An abdominal multidetector computed tomography (MDCT) scan was suggestive of intestinal ischaemia. At laparotomy, the terminal ileum was ischaemic and extensive colonic necrosis was found, sparing only the proximal third of the transverse colon. The rectum was also spared. The terminal ileum and the entire colon were resected and an end ileostomy was fashioned. Although the

High quality cardiopulmonary resuscitation (CPR) is crucial for influencing survival from cardiac arrest. Healthcare professionals are expected to know how to perform CPR as they may encounter emergency situations during their work. Physiotherapists, who use exercise as a therapeutic approach, should have good knowledge and skills in CPR not only to cope with possible adverse cardiac events during exercise but also because a widespread CPR application and early defibrillation can greatly reduce mortality due to heart attack. The aim of this study is to investigate knowledge of Greek physiotherapists in European Resuscitation Council guidelines for resuscitation. A secondary aim of this study was to assess and compare the knowledge score between those with and without previous training and/or lower self-confidence in CPR skills. Three hundred and fifty Greek physiotherapists who were working in hospitals and rehabilitation centres (face-to-face and e-mail contact) were randomly selected to ...
AIM OF THE STUDY: As most cardiopulmonary resuscitation (CPR) efforts last longer than 15min, the aim of this study was to compare brain blood flow between the Head Up (HUP) and supine (SUP) body positions during a prolonged CPR effort of 15min, using active compression-decompression (ACD) CPR and impedance threshold device (ITD) in a swine model of cardiac arrest. METHODS: Ventricular fibrillation (VF) was induced in anesthetized pigs. After 8min of untreated VF followed by 2min of ACD-CPR+ITD in the SUP position, pigs were randomized to 18min of continuous ACD-CPR+ITD in either a 30° HUP or SUP position ...
Background: Few outcome data are available about intraoperative cardiac arrest (IOCA). The authors studied 90-day functional outcomes and their determinants in patients admitted to the intensive care unit after IOCA. Methods: Patients admitted to 11 intensive care units in a period of 2000-2013 were studied retrospectively. The main outcome measure was a day-90 Cerebral Performance Category score of 1 or 2. Results: Of the 140 patients (61 women and 79 men; median age, 60 yr [interquartile range, 46 to 70]), 131 patients (93.6%) had general anesthesia, 80 patients (57.1%) had emergent surgery, and 73 patients (52.1%) had IOCA during surgery. First recorded rhythms were asystole in 73 patients (52.1%), pulseless electrical activity in 44 patients (31.4%), and ventricular fibrillation/ventricular tachycardia in 23 patients (16.4%). Median times from collapse to cardiopulmonary resuscitation and return of spontaneous circulation were 0 min (0 to 0) and 10 min (5 to 20), respectively. Postcardiac ...
The pH in the ROSC group was significantly higher than in the non-ROSC group (6.96 vs. 6.85; P = 0.009). pCO2 and lactate levels in the ROSC group were significantly lower than those in the non-ROSC group (74.0 vs. 89.5 mmHg, P , 0.009; 11.6 vs. 13.6 mmol/L, P = 0.044, respectively). In a multivariate regression analysis, pCO2 was the only independent biochemical predictor for sustained ROSC (OR 0.979; 95% CI 0.960-0.997; P = 0.025) and pCO2 of. pCO2 levels obtained during cardiopulmonary resuscitation on ER arrival was associated with ROSC in OHCA patients. It might be a potentially marker for reflecting the status of the ischemic insult. These preliminary results need to be confirmed in a larger population.. Full Text. Reference:.

Neuronal injury is one of the key factors in determining outcome after cardiac arrest. Cerebral resuscitation starts with rapid restoration of spontaneous circulation by immediate CPR and defibrillation and continues in the postresuscitation period. Basic measures consist of good critical care practice, such as maintaining normotension, normoglycemia, and normocapnia. In addition, several more specific postresuscitation treatment options have been explored in recent years. All therapies for cerebral resuscitation must face the challenge presented by the complex pathophysiological network, which is activated by global ischemia. An effective therapy should act on multiple pathways simultaneously. This is what therapeutic hypothermia does. Two large randomized clinical trials have proven that mild therapeutic hypothermia is effective in improving both survival and neurological outcome of patients after out-of-hospital cardiac arrest. Mild therapeutic hypothermia of 32°C-34°C for 12-24 h is, ...

Background To elucidate the incidence of acute kidney injury (AKI) after out-of-hospital cardiac arrest (OHCA) and to examine the impact of target temperature management (TTM) and early coronary angiography on renal function. Methods Post hoc analysis of the TTM trial, a multinational randomised controlled trial comparing target temperature of 33 °C versus 36 °C in patients with return of spontaneous circulation after OHCA. The impact of TTM and early angiography (within 6 h of OHCA) versus late or no angiography on the development of AKI during the 7-day period after OHCA was analysed. AKI was defined according to modified KDIGO criteria in patients surviving beyond day 2 after OHCA. Results Following exclusions, 853 of 939 patients enrolled in the main trial were analysed. Unadjusted analysis showed that significantly more patients in the 33 °C group had AKI compared to the 36 °C group [211/431 (49%) versus 170/422 (40%) p = 0.01], with a worse severity (p = 0.018).

N2 - Background Little is known about the burden of recurrent out-of-hospital cardiac arrest (OHCA) episodes in initial survivors of OHCA. We sought to investigate the frequency of recurrent OHCA, describe time-to-event trends, and establish baseline predictors of occurrence. Methods Between January 2000 and June 2015, we included consecutive OHCA survivors to hospital discharge from the Victorian Ambulance Cardiac Arrest Registry. Patient identifiers were used to match index and recurrent episodes of OHCA, and death records from a government database. Kaplan-Meier curves and a Cox proportional-hazards model were used to estimate the long-term risk of recurrent OHCA and identify index characteristics associated with their occurrence. Results Among 3581 survivors, 214 (6.0%) experienced a recurrent OHCA over a ...
As noted in part 1 of this series, periprocedural cardiac arrest (PPCA) can differ greatly in etiology and treatment from what is described by the American Heart Association advanced cardiac life support algorithms, which were largely developed for use in out-of-hospital cardiac arrest and in-hospital cardiac arrest outside of the perioperative space. Specifically, there are several life-threatening causes of PPCA of which the management should be within the skill set of all anesthesiologists. However, previous research has demonstrated that continued review and training in the management of these scenarios is greatly needed and is also associated with improved delivery of care and outcomes during PPCA ...

  • The Heart Rhythm Society commends Representatives Capps and Pickering and Senators Crapo and Dorgan for taking a leadership role in bringing SCA to the forefront with the introduction of this important legislation," said Dr. N.A. Mark Estes III, president of the Heart Rhythm Society. (
  • The resolution is supported by the Heart Rhythm Society and the 29 organizations that comprise the Sudden Cardiac Arrest Coalition. (
  • An electrocardiogram shows either no electrical activity in the heart or a rhythm that is inadequate for heart function. (
  • When victims experience cardiac arrest, immediate treatment with a defibrillator (a device that delivers an electrical shock to the heart) can help restore the heart's normal rhythm. (
  • When they detect dangerous arrhythmias, they deliver electrical shocks that help reestablish normal heart rhythm. (
  • These devices - often found in malls, churches, schools and other public spaces - send an electric shock to the heart to try to restore normal rhythm. (
  • Paramedics tried to shock Aidan's heart back into rhythm, and he was transported to the local hospital. (
  • Cardiac arrest was produced by coronary perfusion of potassium chloride in hypothermic dogs during sinus rhythm and during ventricular fibrillation. (
  • In addition to the physiological mechanism being different, the symptoms of a heart attack and a cardiac arrest also vary. (
  • There are various symptoms of a heart attack. (
  • In contrast, the main symptoms of a cardiac arrest are unconsciousness, lack of breathing and no pulse. (
  • If there is any good news about heart attack, it is the fact that it generally occurs with recognisable symptoms. (
  • If symptoms are understood early enough, a person suffering from a heart attack can get professional help. (
  • Just like there is at least some good news about heart attack symptoms, there is good news for cardiac arrest victims as well. (
  • Symptoms include angina, and that of heart failure. (
  • When you notice such symptoms, immediatly contact a cardiothoriac physician for a heart check up. (
  • Sudden cardiac arrest symptoms are immediate and drastic with sudden collapse, no pulse, no breathing and loss of consciousness. (
  • Commenting on the major causes and symptoms of heart diseases, Dr Amit Bhushan Sharma , Unit Head and Associate Director -Interventional Cardiology says, "Symptoms in men are clear than in women. (
  • There are generally no symptoms associated with sudden cardiac arrest, but it's usually a red flag for a serious condition. (
  • The person is awake (conscious) and may complain of one or more of the signs and symptoms of a Heart Attack. (
  • Refrain from driving the person experiencing symptoms of heart attack to the hospital. (
  • Never drive yourself to the hospital if you are experiencing heart attack symptoms. (
  • Symptoms of a heart attack may be immediate and intense. (
  • More often, though, symptoms start slowly and persist for hours, days or weeks before a heart attack. (
  • The heart attack symptoms in women can be different than men. (
  • A heart attack and cardiac arrest can have common symptoms, at least initially, and it is difficult to predict whether a heart attack will lead to cardiac arrest. (
  • During cardiac arrest, the electrical system is negatively impacted by conditions such as cardiomyopathy, heart failure, arrhythmias or ventricular fibrillation. (
  • Most cardiac arrests are caused by arrhythmias (abnormal heart rhythms) that may not be diagnosed ahead of time. (
  • Cardiac arrest is almost always caused by lethal heart arrhythmias. (
  • These include a thickened heart muscle ( cardiomyopathy ), heart failure , arrhythmias, particularly ventricular fibrillation , and long Q-T syndrome . (
  • Fortunately, not all arrhythmias lead to cardiac arrest. (
  • Arrhythmias (abnormal heart rhythms) can interfere with normal heart function. (
  • A heart attack occurs when there is a blockage of the coronary arteries. (
  • Such a blockage, if not quickly resolved, can cause parts of heart muscle to begin to die. (
  • A heart attack is caused by a blockage in a blood vessel that interrupts the flow of blood causing an area of the heart muscle to die. (
  • Cardiac arrest differs from a heart attack, which occurs when a blockage prevents blood flow to the heart, although heart attack and other heart conditions can cause cardiac arrest. (
  • Patients who experience sudden cardiac arrest and are successfully resuscitated are generally taken to the heart catheterization laboratory to determine if a heart blood vessel blockage is what caused the heart to beat irregularly. (
  • heart attack is due to poor blood flow due to blockage of arteries carrying to heart. (
  • coronary arteries which carry the blood from the heart to other body parts or coronary veins which carry blood from other body parts to body will be subjected to blockage if there is any accumulation of dead cells or calcium in the blood vesseles which makes the arteries and veins to loose their elasticity and also formation of hard substances can eventually block the whole vessel in due coarse of time. (
  • The blockage of blood supply to the muscle can lead to the death of heart muscle. (
  • The first thing he remembers clearly is waking up in the hospital in Tacoma, eight days later, having undergone open-heart surgery to correct an 80 to 90 percent blockage in his main coronary artery. (
  • Eight out of 10 times the causes of cardiac arrest in women is a blockage in the heart. (
  • A heart attack happens when there's a sudden blockage in the flow of blood to a section of the heart muscle. (
  • The partnership with Regional Emergency Medical Services Authority will allow responders to send an automated external defibrillator by air in addition to an ambulance dispatch for every emergency call involving cardiac arrest. (
  • The joint delivery program will allow a person on the scene to use the defibrillator on the person suffering cardiac arrest before paramedics arrive. (
  • In fact, medicines have become so effective that many low-risk heart failure patients may not need to receive an implantable cardioverter-defibrillator (ICD) to protect their lives, McMurray and his international colleagues argued. (
  • By doing this, he bought extra time until paramedics arrived and used a defibrillator to jump-start my heart. (
  • It is a defibrillator that can jump-start a stopped heart even as a victim awaits professional medical attention. (
  • There her heart beat stopped and then they revived her with defibrillator. (
  • The Zoll LifeVest is a temporary, wearable defibrillator that will recognize an SCA and shock the heart back to life. (
  • On the third day in hospital he had an implantable cardiac defibrillator (ICD) inserted to reduce his risk of further cardiac arrests. (
  • Eriksen's life was saved when CPR was administered to him on the pitch and his heart was re-started with a defibrillator before he was taken to hospital, where he is recovering. (
  • They will be instructed to either run directly to the cardiac arrest and do CPR, or directed to the nearest defibrillator in the vicinity, which they can use before the emergency services arrive. (
  • According to statistics from TrygFonden, the chances of surviving a heart attack increase from less than 10% to over 70% if the victim receives CPR and a shock from a defibrillator before the ambulance arrives. (
  • Doctors may recommend that patients who are at very high risk for or have survived cardiac arrest undergo surgery to place an implantable cardioverter defibrillator under the skin of their abdomen or chest. (
  • A bystander who sees someone who may be suffering cardiac arrest should call 911 immediately and, if possible, use an automated external defibrillator (AED). (

  • THURSDAY, July 6, 2017 (HealthDay News) -- Heart failure patients are much less likely now to die from sudden cardiac arrest, new research shows. (
  • Patients with heart failure and reduced ejection fraction certainly are living longer, and I think are also living better," McMurray said. (
  • Modern pharmacological and device therapy is very effective, and we are now fairly commonly seeing patients with substantial or even complete recovery of their heart muscle dysfunction. (
  • For this study, researchers analyzed data on more than 40,000 heart failure patients enrolled in 12 clinical trials conducted between 1995 and 2014. (
  • Most heart failure patients develop reduced ejection fraction, a condition in which the lower chambers of the heart (ventricles) do not squeeze hard enough to pump oxygen-rich blood out to the body. (
  • Patients with reduced ejection fraction often die suddenly from cardiac arrest because their ventricles develop a dangerously erratic heartbeat, the researchers explained in background notes. (
  • To prevent this, many heart failure patients receive an ICD, the researchers said. (
  • The combined data from the clinical trials showed that sudden death rates have fallen by 44 percent in heart failure patients who have not received an ICD. (
  • The researchers also found that the rate of sudden death was not higher among newly diagnosed heart failure patients. (
  • UCLA cardiologist Dr. Gregg Fonarow agreed that heart failure patients are living longer and better, thanks to new therapies. (
  • However, Fonarow isn't convinced that heart implants are no longer necessary for many patients. (
  • Patients receiving all of the current guideline-recommended heart failure medications still have a residual risk of sudden death that can be effectively reduced with ICDs," said Fonarow, co-director of the UCLA Preventative Cardiology Program at the David Geffen School of Medicine in Los Angeles. (
  • More research will be needed to identify specific types of heart failure patients who could be treated solely with medicines, said Dr. Chris O'Connor, editor-in-chief of the journal JACC: Heart Failure . (
  • The researchers behind the new study might also be premature in saying that doctors have more time to decide whether an implant is needed for individual patients, added O'Connor, CEO of the Inova Heart and Vascular Institute in Falls Church, Va. (

  • To define the mechanisms of unexpected cardiac arrest in advanced heart failure, we reviewed the causes of cardiac arrest as established from electrocardiographic monitoring and from clinical and autopsy data in patients hospitalized for cardiac transplantation evaluation and management of advanced heart failure (mean left ventricular ejection fraction, 0.18 +/- 0.08) who were stable while on vasodilator and diuretic therapy such that hospital discharge to home was anticipated. (
  • Twenty-one cardiac arrests occurred in 20 of 216 (9%) such patients during a 4-year period. (
  • Heart failure was due to coronary artery disease with prior myocardial infarction in 13 patients and nonischemic cardiomyopathy in seven patients. (
  • The precipitating cause of the BA/EMD arrest was coronary artery thrombosis or embolism in two patients, pulmonary embolism in one patient, hyperkalemia in two patients, and unexplained hypoglycemia in one patient. (
  • In seven of 13 (54%) patients, a precipitating cause of the bradycardia arrest could not be established. (
  • Only eight of 21 (38%) arrests were due to ventricular tachycardia or fibrillation (VT/VF), and all occurred in patients with prior myocardial infarction (p = 0.02 vs. BA/EMD arrests). (

  • The role of coronary spasm in underlying disease-free patients who were resuscitated from sudden cardiac arrest remained uncertain. (
  • This study investigated the cause of cardiac arrest, and the etiologic and prognostic differences were compared between patients with underlying heart disease (group I) and those patients without underlying heart disease (group II). (
  • Fifteen of the patients had underlying heart disease, while 10 did not. (
  • Electrophysiologic abnormalities were found in 13 of the 15 patients in group I. In group II, spontaneous attack of coronary spasm occurred in four patients during the observation period, and coronary spasm was induced in three of the remaining six period of 32 +/- 23 months, whereas no patients in group II had recurrence of sudden cardiac arrest at a median follow-up of 32 months (range, 10 to 72 months).

(
  • A study analyzing the records of nearly 138,000 patients who suffered out-of-hospital-cardiac arrest in the Taiwan National Health Insurance Research Database found that the prior use of statins was associated with higher rates of survival after cardiac arrest than was non-use. (
  • For patients who have already experienced a heart attack or ischemic stroke , cholesterol-lowering statins are often prescribed to prevent a second cardiovascular event. (
  • Because of the large number of patients who have been treated with the popular dialysis additive, the number of GranuFlo cardiac arrest lawsuits is expected to rise, as more patients and families learn of the risks. (
  • Dangerously high levels of sodium often cause heart problems, and hundreds of patients have alleged serious injuries after being treated with GranuFlo. (
  • Furthermore, a 2010 study by Fresenius examined the incidence of sudden death and cardiac arrest among patients. (

  • People hear 'heart failure' and think the heart is no longer working or is about to stop working," Dr. Khan said. (
  • The heart suddenly stops beating normally and cannot pump blood effectively. (
  • A heart attack is when blood flow to the heart is blocked, and sudden cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly. (
  • Cardiac arrest occurs when the heart suddenly stops functioning. (
  • In contrast, there's no such thing as "minor" sudden cardiac arrest, which happens when the heart suddenly stops beating. (
  • Hodge also noted that cardiac arrest is different from a heart attack, where a person is feeling chest pains, sweating, nausea and heaviness in the arms. (

  • 4. How many arteries does a human heart have. (
  • The most common cause of cardiac arrest is a heart attack due to blockages in one or more of the coronary arteries. (
  • These arteries are the blood vessels which supply the heart with blood, oxygen and nutrients. (
  • A heart attack comes when the arteries which supplies blood to the heart muscles gets blocked suddenly. (
  • this is when the major arteries that supply the heart with blood get clogged up with plaques of cholesterol. (
  • During a heart attack, the plaques will cause a blood clot, which then stops the blood supply from running through the arteries to the heart. (
  • Such blockages of brain arteries can be caused by narrowing of the arteries, but can also be caused by "small" blood clots that can come from the heart and "plug" the brain arteries. (
  • They are triggered by the electrical malfunctioning in the heart that causes the heart to beat irregularly. (

  • While the study can't prove whether or how working as a firefighter might make heart disease more likely, several aspects of the job could explain the connection, Smith said. (
  • One limitation of the study is that the autopsies didn't have uniform descriptions of heart disease or criteria for defining an enlarged heart, the authors note. (
  • Researchers also lacked data on certain risk factors for heart disease like smoking or high blood pressure. (
  • In essence, for persons who have developed underlying heart disease, it is dangerous to perform heavy work, especially in stressful situations that produce a surge of adrenaline and related hormones that challenge the cardiovascular system through a variety of mechanisms," Kales said by email. (
  • Therefore, while firefighter screening has traditionally focused on coronary artery disease (cardiac risk factors and stress tests), it should also include imaging such as an echocardiogram to identify possible heart enlargement, increased wall thickness or the presence of an old heart attack," Kales said. (
  • Since cardiac arrest often is the first sign of underlying heart disease, screening and treatment for common heart diseases are critical. (
  • Among these limitations were differences in autopsy descriptions of heart disease, the use of a cut-off weight for an enlarged heart, and lack of information about other risk factors such as smoking and high blood pressure. (

  • Heart attacks increase the risk for sudden cardiac arrest, but most heart attacks do not lead to sudden cardiac arrest. (
  • There are many risk factors that can lead to sudden cardiac arrest. (
  • When these signals go messy the heart stops beating and can lead to sudden death. (
  • Cardiologists measure heart-pumping efficiency by measuring the heart's ejection fraction, the amount of blood pumped by each heartbeat. (
  • Califano's ejection fraction showed that his heart was pumping at only 20 percent efficiency. (
  • Darren was a young man recovering from a serious heart attack, somewhat overweight, and his ejection fraction was only about 20 percent. (

  • While recovering at the Highline Medical Center in Seattle, Califano met cardiologist Arun Kalyanasundaram, MD. 'Dr. Kalyanasundaram told me that I was at risk for sudden cardiac arrest because my heart was not pumping blood efficiently enough yet,' said Califano. (
  • They found that the risk of SCA after heart attack was 8.6 percent, with the highest risk during the first 30 days after the patient leaves the hospital. (
  • I felt he was at significant risk for sudden cardiac arrest,' said Dr. Kalyanasundaram. (
  • Today, heart attacks are striking at a younger age, making those in their 30s and 40s the new high-risk categories, possibly due to high-pressure lifestyles and low levels of calcium. (
  • Lower calcium levels were independent with an increased risk of sudden cardiac arrest in women. (
  • Also, in rural areas, the biggest reason behind the growing numbers and decreasing age in heart-related ailments is low awareness of risk factors. (
  • It is important to educate that no one can be completely safe from the risk of cardiac arrest and it is important to check the level of calcium and to keep the risk factors such as high blood pressure, diabetes, and obesity at a minimum. (
  • The misconception of athletes being at a higher risk for sudden cardiac arrest does a disservice to the public who aren't as aware that any young person is just as susceptible to such a life-threatening event. (

  • Sudden cardiac arrest occurs suddenly and often without warning. (
  • But when sudden cardiac arrest occurs, heart attack is a common cause. (
  • Most heart attacks won't lead to cardiac arrest, however, when a cardiac arrest occurs, a heart attack is one of the most common causes. (
  • The information obtained includes demographic characteristics, arrest location and date, time delays, use of defibrillation and cardiopulmonary resuscitation (CPR), transfer to hospital, and admission. (
  • The other variables associated with successful outcome included younger age, time to defibrillation of 2 minutes or less, and the arrest taking place in a unit with monitoring. (
  • The odds of surviving cardiac arrest decline dramatically during every minute that defibrillation and/or CPR is not provided. (
