Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart.

A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Low adiponectin blood concentration predicts left ventricular remodeling after ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention. (3/56)

BACKGROUND: Left ventricular remodeling (LVR), an increase in left ventricular end-diastolic volume index > or = 20%, is an adverse consequence of myocardial infarction. The aim of this study was to assess the association between LVR and adiponectin, which has been shown to protect against myocardial ischemia-reperfusion injury. METHODS: In 75 patients echocardiographic examination was performed one year after ST-segment elevation myocardial infarction, successfully treated with primary percutaneous coronary intervention (pPCI). Two groups of patients were analyzed: those with LVR (n = 15) and those without LVR (n = 60). RESULTS: The predictors of LVR were: anterior myocardial infarction, glucose at admission, baseline C-reactive protein, adiponectin, and echocardiographic parameters: left ventricular end-diastolic and end-systolic volume indices, ejection fraction < 40% and left ventricular wall motion score index (WMSI) at discharge. On multivariable regression analysis, lower adiponectin level (OR = 0.67, 95% CI 0.49-0.91, p < 0.05) and higher WMSI (OR = 20.14, 95% CI 2.62-154.82, p < 0.01) were the only independent negative predictors of LVR. The optimal cut-off for adiponectin for predicting LVR was < or = 4.7 mg/mL (sensitivity: 73%, specificity: 85%) and this level increased the risk of LVR 15-fold (95% CI 4.05-59.87, p = 0.0001). CONCLUSIONS: Baseline low blood adiponectin concentration, along with WMSI, can be considered as a predictor of the LVR in male patients one year after myocardial infarction and pPCI.  (+info)

Complete atrioventricular block complicating acute anterior myocardial infarction can be reversed with acute coronary angioplasty. (7/56)

INTRODUCTION: A retrospective case series of acute anterior myocardial infarction (MI) patients complicated by complete atrioventricular block (AVB) treated with acute percutaneous transluminal coronary angioplasty (PTCA). CLINICAL PICTURE: Eight patients with anterior MI and complete AVB underwent acute PTCA between 2000 and 2005. Mean onset of complete AVB was 16.6 +/- 16.9 hours from chest pain onset. TREATMENT: All patients underwent successful PTCA to the left anterior descending artery. OUTCOME: Complete AVB resolved with PTCA in 88%; mean time of resolution was 89 +/- 144 minutes after revascularisation. One patient had permanent pacemaker implanted at Day 12 after developing an 8-second ventricular standstill during hospitalisation but not pacing-dependent on follow-up. The rhythm on discharge for the other surviving patients was normal sinus rhythm. CONCLUSION: This case series suggests that complete AVB complicating anterior MI is reversible with acute PTCA and survivors are not at increased risk of recurrent AVB. Nevertheless, this condition is associated with extensive myocardial damage and high mortality during the acute hospitalisation was not improved with correction of AVB with temporary pacing.  (+info)

Coronary flow velocity pattern and recovery of regional left ventricular function: the relationship observed in patients with reperfused acute myocardial infarction. (8/56)

Coronary flow velocity pattern (CFVP) recorded within 3 days of percutaneous coronary intervention (PCI) has been reported to be useful in predicting left ventricular (LV) function. The aim of this prospective study was to investigate, via transthoracic Doppler echocardiography, whether the relationship between CFVP and recovery of LV function persists. Our study group comprised 37 patients with 1st anterior-wall acute myocardial infarction who underwent successful PCI for lesions in the left anterior descending coronary artery (LAD). The CFVP in the LAD was recorded at 24-48 hours, 7 days, and 4 weeks after PCI. Myocardial contrast echocardiography was performed at 24-48 hours after PCI. The diastolic deceleration time (DDT) at each stage correlated significantly with the regional LV wall-motion score index at 6-month follow-up (r=-0.58 at 24-48 hr, -0.57 at day 7, and -0.50 at week 4; P <0.01 for all). The mean DDT increased over time. Optimal cutoff values for DDT to predict regional LV wall-motion score indices of <2.0 were 327 ms at 24-48 hours (sensitivity, 0.78; specificity, 0.64), 495 ms at day 7 (sensitivity, 0.75; specificity, 0.69), and 525 ms at week 4 (sensitivity, 0.83; specificity, 0.69). The DDT at 24-48 hours significantly correlated, better than the peak creatine kinase value, with reperfusion (r=0.68, P <0.01) as defined by myocardial contrast echocardiography. In conclusion, CFVP in the LAD can be used, within 4 weeks after PCI, to predict the recovery of regional LV function in patients with reperfused anterior-wall acute myocardial infarction.  (+info)

The heartmuscle itself is very limited in its capacity to extract oxygen in the blood that is being pumped. Only the inner layers (the endocardium) profit from this oxygenrich blood. The outer layers of the heart (the epicardium) are dependent on the coronary arteries for the supply of oxygen and nutrients. With aid of an ECG, the occluded coronary can be identified. This is valuable information for the clinician, because treatment and complications of for instance an anterior wall infarction is different than those of an inferior wall infarction. The anterior wall performs the main pump function, and decay of the function of this wall will lead to decrease of bloodpressure, increase of heartrate, shock and on a longer term: heart failure. An inferior wall infarction is often accompanied with a decrease in heartrate because of involvement of the sinusnode. Longterm effects of an inferior wall infarction are usually less severe than those of an anterior wall infarction. The heart is supplied of ...
Magnetic resonance tagging was used to calculate myocardial strains (15). All studies were obtained on a 1.0-tesla MR unit (Siemens, Erlangen, Germany). Tags are noninvasive markers placed on the myocardium by presaturating planes at end-diastole perpendicular to the subsequent imaging planes. They show up on the images as dark lines that move and deform with the myocardium on which they are inscribed. Five parallel short-axis planes and four radially oriented long-axis planes crossing the center of the LV were defined (Fig. 1). The gravitational centerline of the LV cavity was reached by the best fit connecting the center of the cavity at each of the different short-axis levels. Images were acquired at end-diastole and end-systole in all these planes, using the short-axis planes as tagging planes for the long-axis images and vice versa. By combining the short- and long-axis information, the entire LV wall, except for the apex, could be reconstructed into 32 small cuboids for which the ...

The simplicity of this equation system, especially when restricted to only a few species, makes it ideal for introducing undergraduates to mathematical modeling and research.. Tilman[1982] argues persuasively based on these equations that, with three nutrients available, at most three species may coexist, but this result contradicts the diversity of species in our ecosystem. Explaining the physical and biological processes that maintain diversity, including finding mathematical models that show how diverse ecosystems develop and interact, are overarching questions.. My current work includes identifying mechanisms that allow two species to coexist in nature, even though chemostat experiments and initial numerical models indicate one should out-compete and exclude the other species. Future work will include addressing the question by which mechanisms do meta-communities (Hanski[2004]), e.g. lakes connected by rivers, promote diversity in the ecosystem. This involves much more complicated ...

SCVS 2018 Abstracts: Statins Reduce Mortality And Failure To Rescue after Myocardial Infarction Following Aortobifemoral Bypass In Aortoiliac Occlusive Disease Patients
OBJECTIVES: We sought to evaluate regional morphology and function in patients in their first week after having a reperfused anterior myocardial infarction (MI) using magnetic resonance (MR) myocardial tagging. BACKGROUND: The mechanism of myocardial dysfunction in the remote, noninfarct-related regions is an unresolved issue to date. METHODS: Sixteen patients with a first reperfused transmural anterior MI were studied with MR tagging at 5 +/- 2 days after the event, and the results were compared with those of an age-matched control group regions. The left ventricle (LV) was divided into infarct, adjacent and remote regions. Magnetic resonance tagging provided information on the regional ventricular morphology and function. RESULTS: Morphologically, an increase of the circumferential radius of curvature was found in the remote myocardium, whereas the longitudinal radius of curvature was increased in all regions of the LV. A significant increase in apical sphericity was also found. A significant ...

An anterior MI was ...

Horizontal plane projections of vectorcardiograms registered by the Frank lead system were analyzed in 36 patients with left ventricular hypertrophy and in 24 with left ventricular hypertrophy and associated anterior wall infarction. All were studied at autopsy. The 0.01-, 0.02-, 0.03-second, and maximum QRS vectors were compared with similar measurements in 60 control subjects previously reported. New criteria for the vector-cardiographic diagnosis of left ventricular hypertrophy have been outlined. Close agreement with earlier reported groups of patients with anteroseptal and anterolateral infarction was found, and findings by others in patients with left ventricular hypertrophy were confirmed.. The direction of the 0.02-second QRS vector allowed the separation of the infarct group from the left ventricular hypertrophy group and from the normal, whereas the direction of the 0.03-second and maximum QRS vectors separated left ventricular hypertrophy from the normal. The magnitude of the maximum ...

Of the clinical variables examined by multiple logistic regression analysis, only patient age and anterior wall myocardial infarction correlated with the need for urgent cardiac catheterization (p = 0.0016 and p = 0.017, respectively). Of the 75 patients undergoing urgent coronary angiography, only 39% had an occluded infarct-related artery. Emergency coronary angioplasty was performed in 49% of the patients and coronary artery bypass graft surgery was performed urgently in 3%. Despite these interventions, the need for urgent cardiac catheterization was associated with an in-hospital mortality rate of 7% (vs. 3% in the group not requiring urgent angiography, p = 0.36); mean left ventricular ejection fraction was 50.5 ±11% (vs. 54.3 ±10.8%, p = 0.12) and regional infarct zone wall motion was -2.68 ±1.07 SD/chord (vs. -2.46 ±1.19 SD/chord; p = 0.44).. ...

We studied the evolution of body-surface potential map (BSPM) patterns in 32 patients following first acute inferior myocardial infarction. Initial BSPMs were obtained at a mean of 79 hours post-infarction; follow-up BSPMs, a mean of eight months post-infarction. Temporal area-of-difference maps, constructed by subtracting initial from follow-up group-mean BSPMs, revealed reciprocal changes over the superior and inferior torso for both Q-zone and ST-segment time-integral distributions. The temporal changes in Q-zone patterns were small but definite: over the inferior torso there was a relative gain in Q-zone values and, over the superior torso, a relative decrease. In contrast, there were marked spatial and quantitative changes of ST-segment distributions during the follow-up period. Over the superior torso, particularly anteriorly, there was a gain in ST-segment values; over the inferior torso, a decrease. With the small temporal changes in Q-zone time-integral distributions, individual Q-zone maps
The xanthine oxidase inhibitor allopurinol that is commonly used to treat gout, has been suggested to have pleiotropic effects that are likely to reduce the incidence of myocardial infarction (MI) in at risk individuals. The aim of this meta-analysis was to assess the efficacy of allopurinol treatment in reducing the incidence of MI. MEDLINE, Scopus, Web of Science, and Cochrane Library databases were searched for randomised controlled trials examining the efficacy of allopurinol in reducing the incidence of MI. The quality of study methodology was assessed by two independent reviewers using the Cochrane Collaborations tool for assessing risk of bias. This meta-analysis was conducted using a fixed-effects model, and heterogeneity was assessed with the I2 index. One thousand one hundred twenty-three citations were screened and only six studies satisfied the inclusion criterion. Published between 1988 and 1995, all studies examined the cardioprotective efficacy of allopurinol in the setting of coronary

Background Survivors of anterior MI are in increased risk for heart stroke with predilection to create ventricular thrombus. buy KRN 633 therapy. Within 4 years, 169 sufferers (5.7%) were admitted with an ischemic buy KRN 633 stroke, fifty percent which occurred within 1-calendar year post-MI. There is no factor in heart stroke price between anterior and non-anterior MI sufferers. The usage of warfarin up to 3 months was not connected with stroke security after anterior MI (threat proportion [HR], 0.68; 95% self-confidence period [CI], 0.37C1.26). The usage of angiotensin-converting-enzyme inhibitors (HR, 0.65; 95% CI, 0.44C0.95) and beta-blockers (HR, 0.60; 95% CI, 0.41C0.87) were connected with a significant reduction in heart stroke risk. There is no factor in bleeding-related hospitalizations in individuals who utilized warfarin for 3 months post-MI. Summary Many professionals still look at a huge buy KRN 633 anterior-wall MI as risky for potential LV thrombus development and heart stroke. ...
T-wave polarity in V1 to V3 was examined in 70 patients with acute inferior wall myocardial infarctions (IWMI) as an indicator of significant disease in the left anterior descending coronary artery (LAD). Fifty-three percent (37/70) had precordial T-wave inversions, and of these 38 percent (14/37) had angiographically significant LAD disease. Conversely, 47 percent (33/70) had upright T waves in V1 to V3, and of these, 52 percent (17/33) had significant LAD disease. Likewise, 41 percent of the patients with ST segment depression in V1 to V3 had significant LAD disease, while 50 percent of those with isoelectric ST segments were similarly affected ...
So what would I do?? I think there is some question on the initial ECG as to whether the ST elevation is definitely new (though I would highly suspect that it is). I would get serial ECGs for a longer time, get an immediate formal echo, and ultimately I believe that these would be convincing of acute (probably reperfused) STEMI. The positive initial trop would help, but this would be positive in a nonSTEMI also. Once convinced that the STE is new, I would activate the cath lab because acute anterior STEMI, even if reperfused, is extremely unstable and dangerous. ...

OBJECTIVE: To investigate the value of a giant negative T wave (, or = 1.0 mV) in precordial leads of 12-lead electrocardiograms in the acute phase of Q wave myocardial infarction as a predictor of myocardial salvage. METHODS: Coronary angiographic and electrocardiographic findings, left ventricular ejection fraction in the chronic stage, and levels of cardiac enzymes were compared in patients with myocardial infarction with (group GNT, n = 31) and without (group N, n = 20) a giant negative T wave. GNT patients were divided into two subgroups according to the presence (GNT:R[+], n = 10) or absence (GNT: R[-], n = 21) of R wave recovery with an amplitude , or = 0.1 mV in at least one lead that had shown Q waves. RESULTS: The maximum level of creatine kinase and the total creatine kinase were lower in group GNT compared with group N (P , 0.05). The left ventricular ejection fraction was higher in group GNT than in group N (P , 0.05). The maximum creatine kinase and total creatine kinase were lower ...

Context. Despite numerous publications showing rhythm disturbance and hypotension caused by mad-honey intoxication, none of the findings are associated with ischemic heart disease. Case details. A 48-year-old patient was admitted to emergency service with acute anterior wall myocardial infarction after ingestion of mad-honey. Stent was implanted to the 99% stenosis lesion in the mid-portion of left anterior descending coronary artery. In this case, pollen analysis showed the suspected honey heavily contaminated with Rhododendron species pollen. Discussion. Mad-honey intoxication cases often apply to emergency service with similar signs and symptoms of acute coronary syndrome; therefore it may cause acute coronary syndrome to be bypassed. This also shows that in the cases of mad-honey intoxication, suspected honey pollen and/or toxin analysis should be done to confirm the diagnosis of mad-honey intoxication. ...
The effect of sublingual nitroglycerin (NTG) on myocardial ischemic injury was evaluated in eleven patients with acute anterior myocardial infarction. Precordial 35-lead ST-segment maps were obtained in each patient immediately before and 3-10 minutes after 0.4 mg sublingual NTG. The following measurements were made from each ST map: N-ST (number of leads showing ST elevation greater than 1mm), sigmaST (total ST elevation in all leads), ST (average ST-segment elevation in those leads with less than 1mm elevation). Following 0.4 mg sublingual NTG evidence of myocardial ischemic injury as assessed by ST-segment mapping decreased in association with reduction of heart rate X systolic blood pressure product (10.80 X 10(3) to 9.49 X 10(3), P less than 0.001). Group mean values diminished significantly for N-ST (18.1 to 14.4, P less than 0.001), sigma ST (37.9 to 30.1 P less than 0.005) and ST (1.7 to 1.4, P less than 0.001). Evaluation performed by the technique of precordial ST-segment mapping ...

A 72-year-old female was admitted to the CCU with a recent onset of progressive breathlessness for bedside pericardial drainage for chronic pericardial effusion. After an uncomplicated drainage procedure, initially a serous straw coloured fluid was aspired with subsequent hemorrhagic aspiration with haemoglobin value similar to the peripheral blood. The patient showed initially transient improvement followed by rapid deterioration into severe shock and death. Signs of infero-posterior myocardial infarction (MI) were seen on the ECG. Before death, further interventions were refused by her and her family but a permission was given for autopsy. At autopsy, right ventricular rupture was seen with a 0.6 cm tear with a large amount of 800 cc bloody fluid with clots. The result of histopathologic study of the tear was resembling three-days old MI. The drain was found to be properly localized in the pericardial space, was not blocked and caused no harm to the myocardium. Furthermore, histopathologic examination

The Anderson Wilkins (AW) electrocardiographic acuteness score has been shown to complement the historical timing in estimating the time interval from acute thrombotic coronary occlusion in patients presenting with chest pain and evolving myocardial infarction. The purposes of this study were to (1) compare the distributions of the previously developed AW acuteness score in a training population with either anterior or inferior AMI and (2) propose modifications to the formula to achieve distributions similar to the observed distributions of historical times from onset of pain. Methods Two hundred three and 177 patients were included as training and testing population, respectively. All patients had an anterior or an inferior AMI and were without confounding factors on the electrocardiogram. Results The training population had similar ...

This is named for obvious reasons. The J point is elevated and, along with the T wave, and it looks like a tombstone. In an anterior MI that shows tombstoning, there is frequently 4 to 6 millimeter of ST segment elevation. Do not confuse the ST segment elevation with the T wave. Look specifically where the ST segment is - waaaaay up from the baseline. Recall that the J point is where we need to measure the elevation from baseline, and the baseline is always the TP segment (between the T wave and the P wave).. ...

In describing the pseudo-sci-fi dystopian anti-Heimat film I Love You, I Kill You (1971) aka Ich liebe dich, ich töte dich directed by unfortunately forgotten German New Cinema auteur Uwe Brandner (Blinker, 50/50 aka Halbe-Halbe), Austrian-born Jewish-American cineaste Amos Vogel wrote in his magnum opus Film as a Subversive Art (1974), Through stylized acting, mysterious silences, disrupted sentences and frozen action, an atmosphere of alienation and stagnation permeates what the director ironically calls a picture-book story of our Vaterland -- a vicious satire of the sentimental German Heimat films of the past. Personally, I think Vogel is at least half-wrong and merely spurred by his hatred of Teutons and the fact he was forced to flee Austria as a teenager due to Uncle Adolfs Anschluß in 1938, as I Love You, I Kill You is less a satire than a conspicuously culturally pessimistic depiction of the Fatherlands deluge as a result of the Second World War as directed by a filmmaker who, ...
