Phosphotransferases that catalyzes the conversion of 1-phosphatidylinositol to 1-phosphatidylinositol 3-phosphate. Many members of this enzyme class are involved in RECEPTOR MEDIATED SIGNAL TRANSDUCTION and regulation of vesicular transport with the cell. Phosphatidylinositol 3-Kinases have been classified both according to their substrate specificity and their mode of action within the cell.
MAP Kinase Signaling System
An intracellular signaling system involving the MAP kinase cascades (three-membered protein kinase cascades). Various upstream activators, which act in response to extracellular stimuli, trigger the cascades by activating the first member of a cascade, MAP KINASE KINASE KINASES; (MAPKKKs). Activated MAPKKKs phosphorylate MITOGEN-ACTIVATED PROTEIN KINASE KINASES which in turn phosphorylate the MITOGEN-ACTIVATED PROTEIN KINASES; (MAPKs). The MAPKs then act on various downstream targets to affect gene expression. In mammals, there are several distinct MAP kinase pathways including the ERK (extracellular signal-regulated kinase) pathway, the SAPK/JNK (stress-activated protein kinase/c-jun kinase) pathway, and the p38 kinase pathway. There is some sharing of components among the pathways depending on which stimulus originates activation of the cascade.

A CALMODULIN-dependent enzyme that catalyzes the phosphorylation of proteins. This enzyme is also sometimes dependent on CALCIUM. A wide range of proteins can act as acceptor, including VIMENTIN; SYNAPSINS; GLYCOGEN SYNTHASE; MYOSIN LIGHT CHAINS; and the MICROTUBULE-ASSOCIATED PROTEINS. (From Enzyme Nomenclature, 1992, p277)
A PROTEIN-TYROSINE KINASE family that was originally identified by homology to the Rous sarcoma virus ONCOGENE PROTEIN PP60(V-SRC). They interact with a variety of cell-surface receptors and participate in intracellular signal transduction pathways. Oncogenic forms of src-family kinases can occur through altered regulation or expression of the endogenous protein and by virally encoded src (v-src) genes.
Protein Kinase C
An serine-threonine protein kinase that requires the presence of physiological concentrations of CALCIUM and membrane PHOSPHOLIPIDS. The additional presence of DIACYLGLYCEROLS markedly increases its sensitivity to both calcium and phospholipids. The sensitivity of the enzyme can also be increased by PHORBOL ESTERS and it is believed that protein kinase C is the receptor protein of tumor-promoting phorbol esters.

A group of protein-serine-threonine kinases that was originally identified as being responsible for the PHOSPHORYLATION of CASEINS. They are ubiquitous enzymes that have a preference for acidic proteins. Casein kinases play a role in SIGNAL TRANSDUCTION by phosphorylating a variety of regulatory cytoplasmic and regulatory nuclear proteins.
Ribosomal Protein S6 Kinases
A family of protein serine/threonine kinases which act as intracellular signalling intermediates. Ribosomal protein S6 kinases are activated through phosphorylation in response to a variety of HORMONES and INTERCELLULAR SIGNALING PEPTIDES AND PROTEINS. Phosphorylation of RIBOSOMAL PROTEIN S6 by enzymes in this class results in increased expression of 5' top MRNAs. Although specific for RIBOSOMAL PROTEIN S6 members of this class of kinases can act on a number of substrates within the cell. The immunosuppressant SIROLIMUS inhibits the activation of ribosomal protein S6 kinases.

The extracellular signal regulated MAP kinases are regulated by a broad variety of CELL SURFACE RECEPTORS and can be activated by certain CARCINOGENS.
MAP Kinase Kinase 4
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. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Clinical evaluation of the first medical whole blood, point-of-care testing device for detection of myocardial infarction. (1/344)BACKGROUND: Validation of whole blood, point-of-care testing devices for monitoring cardiac markers to aid clinicians in ruling in and ruling out myocardial infarction (MI) is necessary for both laboratory and clinical acceptance. METHODS: This study evaluated the clinical diagnostic sensitivity and specificity of the First Medical Cardiac Test device operated by nursing and laboratory personnel that simultaneously measures cardiac troponin I (cTnI), creatine kinase (CK) MB, myoglobin, and total CK on the Alpha Dx analyzer in whole blood for detection of MI. Over a 6-month period, 369 patients initially presenting to the emergency department with chest pain were evaluated for MI using modified WHO criteria. Eighty-nine patients (24%) were diagnosed with MI. RESULTS: In whole blood samples collected at admission and at 3- to 6-h intervals over 24 h, ROC curve-determined MI decision limits were as follows: cTnI, 0.4 microgram/L; CKMB, 7.0 microgram/L; myoglobin, 180 microgram/L; total CK, 190 microgram/L. Based on peak concentrations within 24 h after presentation, the following sensitivities (+/- 95% confidence intervals) were found: cTnI, 93% +/- 5.5%; myoglobin, 81% +/- 9.7%; CKMB, 90% +/- 6.3%; total CK, 86% +/- 7.5%. Sensitivities were maximal at >90% for both cTnI and CKMB at >12 h in MI patients, without differences between ST-segment elevation and non-ST-segment elevation MI patients. CONCLUSIONS: The First Medical point-of-care device provides cardiac marker assays that can be used by laboratories and clinicians in a variety of hospital settings for ruling in and ruling out MI.

Selective antioxidant enzymes during ischemia/reperfusion in myocardial infarction. (2/344)The study of ischemia/reperfusion injury included 25 patients in the acute phase of myocardial infarction (19 perfused, 6 remained non-reperfused as evaluated according to the time course of creatine kinase and CK-MB isoenzyme activity) and a control group (21 blood donors). Plasma level of malondialdehyde was followed as a marker of oxidative stress. Shortly after reperfusion (within 90 min), a transient increase of malondialdehyde concentration was detected. The return to the baseline level was achieved 6 h after the onset of therapy. The activity of a free radical scavenger enzyme, plasma glutathione peroxidase (GPx), reached its maximum 90 min after the onset of treatment and returned to the initial value after 18 h. The specificity of the GPx response was confirmed by comparing with both non-reperfused patients and the control group, where no significant increase was detected. The erythrocyte Cu,Zn-superoxide dismutase (SOD) did not exhibit significant changes during the interval studied in perfused patients, probably due to the stability of erythrocyte metabolism. In non-reperfused patients, a decrease of SOD was found during prolonged hypoxia. These results help to elucidate the mechanisms of fast activation of plasma antioxidant system during the reperfusion after myocardial infarction. (+info)
Safe discharge from the cardiac emergency room with a rapid rule-out myocardial infarction protocol using serial CK-MB(mass). (3/344)OBJECTIVE: To determine whether a new protocol, using a rapid and sensitive CK-MB(mass) assay and serial sampling, can rule out myocardial infarction in patients with chest pain and decrease their length of stay in the cardiac emergency room without increasing risk. DESIGN: The combined incidence of cardiac death and acute myocardial infarction at 30 days, six months, and 24 months of follow up were compared between patients discharged home from the cardiac emergency room after ruling out myocardial infarction with a CK-MB(activity) assay in 1994 and those discharged home after a rapid CK-MB(mass) assay in 1996. SETTING: Cardiac emergency room of a large university hospital. PATIENTS: In 1994 and 1996, 230 and 423 chest pain patients, respectively, were discharged home from the cardiac emergency room with a normal CK-MB and an uneventful observation period. RESULTS: The median length of stay in the cardiac emergency room was significantly reduced, from 16.0 hours in 1994 to 9.0 hours in 1996 (p < 0.0001). Mean event rates in patients from the 1994 and 1996 cohorts, respectively, were 0.9% (95% confidence interval (CI) -0.3% to 2.1%) v 0.7% (95% CI -0.1% to 1. 5%) at 30 days, 3.0% (95% CI 0.8% to 5.2%) v 2.8% (95% CI 1.2% to 4. 4%) at six months, and 7.0% (95% CI 3.7% to 10.3%) v 5.7% (95% CI 3. 5% to 7.9%) at 24 months. Kaplan-Meier survival analysis showed no difference in mean event-free survival at 30 days, six months, and 24 months of follow up. CONCLUSIONS: Using a rule-out myocardial infarction protocol with a rapid and sensitive CK-MB(mass) assay and serial sampling, the length of stay of patients with chest pain in the cardiac emergency room can be reduced without compromising safety.

Assessment of coronary reperfusion in patients with myocardial infarction using fatty acid binding protein concentrations in plasma. (4/344)OBJECTIVE: To examine whether successful coronary reperfusion after thrombolytic treatment in patients with confirmed acute myocardial infarction can be diagnosed from the plasma marker fatty acid binding protein (FABP), for either acute clinical decision making or retrospective purposes. DESIGN: Retrospective substudy of the GUSTO trial. SETTING: 10 hospitals in four European countries. PATIENTS: 115 patients were treated with thrombolytic agents within six hours after the onset of acute myocardial infarction. Patency of the infarct related artery was determined by angiography within 120 minutes of the start of thrombolysis. MAIN OUTCOME MEASURES: First hour rate of increase in plasma FABP concentration after thrombolytic treatment, compared with increase in plasma myoglobin concentration and creatine kinase isoenzyme MB (CK-MB) activity. Infarct size was estimated from the cumulative release of the enzyme alpha hydroxybutyrate dehydrogenase in plasma during 72 hours, or from the sum of ST segment elevations on admission. Logistic regression analyses were performed to construct predictive models for patency. RESULTS: Complete reperfusion (TIMI 3) occurred in 50 patients, partial reperfusion (TIMI 2) in 36, and no reperfusion (TIMI 0+1) in 29. Receiver operating characteristic (ROC) curve analyses showed that the best performance of FABP was obtained when TIMI scores 2 and 3 were grouped and compared with TIMI score 0+1. The performance of FABP as a reperfusion marker was improved by combining it with alpha hydroxybutyrate dehydrogenase infarct size, but not with an early surrogate of infarct size (ST segment elevation on admission). In combination with infarct size FABP performed as well as myoglobin (areas under the ROC curve 0.868 and 0.857, respectively) and better than CK-MB (area = 0.796). At optimum cut off levels, positive predictive values were 97% for FABP, 95% for myoglobin, and 89% for CK-MB (without infarct size, 87%, 88%, and 87%, respectively), and negative predictive values were 55%, 52%, and 50%, respectively (without infarct size, 44%, 42%, and 34%). CONCLUSIONS: FABP and myoglobin perform equally well as reperfusion markers, and successful reperfusion can be assessed, with positive predictive values of 87% and 88%, or even 97% and 95% when infarct size is also taken into account. However, identification of non-reperfused patients remains a problem, as negative predictive values will generally remain below 70%. (+info)
Detection of minor myocardial injury after successful percutaneous transluminal coronary angioplasty with or without stenting. (5/344)Cardiac troponins are sensitive and specific markers for the detection of minor myocardial injury. However, they have been rarely used to monitor myocardial injury after coronary stenting. The purpose of the study was to measure cardiac troponin I (cTnI) and cardiac troponin T (cTnT) levels after apparently successful percutaneous transluminal coronary angioplasty (PTCA) with or without coronary stenting and to compare their results with serum creatine kinase (CK) and its isoform, creatine kinase-MB (CKMB). CTnI and cTnT levels were compared with those of CK or CKMB in 50 consecutive patients with stable angina undergoing visually successful PTCA with stenting (n = 35) or without stenting (n = 15). Cardiac TnI, cTnT, CK and CKMB levels were measured before and 6, 24, and 48 hours after the procedures was performed. None of the patients had abnormal cTnI or cTnT levels, CK activity, or CKMB levels before the procedures. Moreover, no patient showed electrocardiographic evidence of myocardial infarction. 13 patients (26%) had abnormal peak values of one or more markers at 24 hours after coronary intervention. Troponin I was elevated in 10/35 patients after coronary stenting (29%) and in 2/15 patients after PTCA (13%) (P = 0.327). Troponin T was elevated in 6 patients (17%) and CKMB activity was elevated in 3 patients (9%) of the coronary stenting group. CTnI was more significant than CKMB (P = 0.023) in detecting minor myocardial injury. When compared with cTnI and CKMB, cTnT did not reach significance (P = 0.129 and 0.489, respectively). 5 out of the 13 patients with abnormal markers (38%) developed side branch occlusion after stenting. In conclusion, cTnI was a very sensitive marker in detecting minor myocardial injury after coronary angioplasty with or without stenting. The frequency of increased serum levels of cardiac troponins was higher in patients undergoing stent implantation than in those treated with angioplasty alone but did not reach significance. Side branch occlusion may have accounted for some, but not all, periprocedural minor myocardial injury in the stent group. (+info)
Effects of implantable cardioverter defibrillator implantation and shock application on biochemical markers of myocardial damage. (6/344)BACKGROUND: Implantable cardioverter defibrillator (ICD) implantation is a common approach in patients at high risk of sudden cardiac death. To check for normal function, it is necessary to test the ICD. For this purpose, repetitive induction and termination of ventricular fibrillation by direct current shocks is required. This may lead to minor myocardial damage. Cardiac troponin T (cTnT) and I (cTnI) are specific markers for the detection of myocardial injury. Because these proteins usually are undetectable in healthy individuals, they are excellent markers for detecting minimal myocardial damage. The objective of this study was to evaluate the effect of defibrillation of induced ventricular fibrillation on markers of myocardial damage. METHODS: This study included 14 patients who underwent ICD implantation and intraoperative testing. We measured cTnT, cTnI, creatine kinase MB (CK-MB) mass, CK activity, and myoglobin before and at definite times after intraoperative shock application. RESULTS: Depending on the effectiveness of shocks and the energy applied, the cardiac-specific markers cTnT and cTnI, as well as CK-MB mass, showed a significant increase compared with the baseline value before testing and peaked for the most part 4 h after shock application. In contrast, the increases in CK activity and myoglobin were predominantly detectable in patients who received additional external shocks. CONCLUSIONS: ICD implantation and testing leads to a short release of cardiac markers into the circulation. This release seems to be of cytoplasmic origin and depends on the number and effectiveness of the shocks applied. (+info)
Production of recombinant human creatine kinase (r-hCK) isozymes by tandem repeat expression of M and B genes and characterization of r-hCK-MB. (7/344)BACKGROUND: Serum creatine kinase-MB isoenzyme (CK-MB) is widely used as a marker of myocardial injury. We prepared recombinant human CK (r-hCK) MB isoenzyme and examined its potential for use as a control material for assay of CK-MB in serum. METHODS: cDNAs encoding CK-M and CK-B subunits were inserted into the same plasmid vector, followed by transformation of Escherichia coli. The resulting three types of CK isoenzymes were purified by conventional chromatography. RESULTS: The ratio of MB to MM to BB was 50:40:10 on the basis of CK activity. Highly purified CK-MB with a specific activity of 533 U/mg was produced in a yield of 5.7 mg/g of packed cells. Purified r-hCK-MB had the isoelectric point (pI 5.3) and molecular size (46 kDa for the subunit) of native CK-MB. Its immunoreactivity in an ELISA using antibody against native heart enzyme was similar to that of cardiac CK-MB. The r-hCK-MB retained >90% activity for at least 4 months at 11 degrees C in a delipidated serum matrix in a liquid form at a concentration of 118 U/L. CONCLUSIONS: r-hCK-MB shows key properties of the native cardiac isoenzyme and may be useful as a control and calibrator for serum assays of CK-MB. (+info)
Reactivation of ischemic events in acute coronary syndromes: results from GUSTO-IIb. Gobal Use of Strategies To Open occluded arteries in acute coronary syndromes. (8/344)OBJECTIVES: We sought to determine the incidence of and risk factors for thrombotic events early after discontinuing antithrombin therapy in patients with acute coronary syndromes. BACKGROUND: Discontinuation of treatment with heparin and other thrombin inhibitors in patients with unstable coronary syndromes has related to clinical and biochemical evidence of early reactivation of thrombosis. METHODS: We studied 8,943 of the 12,142 patients with acute coronary syndromes enrolled in the Global Use of Strategies To Open occluded arteries in acute coronary syndromes trial of hirudin versus heparin. We excluded patients who received no study drug, lacked timing data, died or had myocardial (re)infarction [(re)MI] during study-drug infusion, or began heparin treatment within 2 h after treatment with the study drug was stopped. We assessed the incidence and timing of (re)MI by type and timing of antithrombin treatment. RESULTS: In all, 215 patients (2.4%) suffered (re)MI, 49 within 12 h of antithrombin therapy discontinuation and 166 between hour 12 and hospital discharge. The duration of infusion did not differ between the hirudin and heparin groups. The rate of early re(MI) after drug therapy discontinuation was significantly higher in patients given heparin versus hirudin (0.8% vs. 0.3%, p = 0.002). Patients with (re)MI had higher mortality at 30 days (23.6% vs. 2.4%, p = 0.001) and 1 year (35.2% vs. 6.7%, p = 0.001) compared with patients without (re)MI. CONCLUSIONS: The incidence of (re)MI was clustered within 12 h of heparin therapy discontinuation, with the greatest risk within 4 h. There was no evidence of early reactivation of thrombotic events after hirudin. Patients who had (re)infarction had worse outcomes. Better understanding of the mechanism and possible prevention of recurrent thrombosis is needed. (+info)
Impact of Coronary Plaque Composition on Cardiac Troponin Elevation After Percutaneous Coronary Intervention in Stable Angina...
Percutaneous coronary intervention (PCI) may be complicated by post-procedural myocardial injury/infarction as manifested by elevated cardiac biomarkers such as creatine kinase-myocardial band or troponin T. The occurrence of post-procedural myocardial injury/infarction has been shown to be associated with worse short- and long-term clinical outcome (1,2), and even mild elevation of cardiac troponin after PCI has been related to a worse prognosis (3). Intravascular ultrasonography (IVUS) has shown that post-procedural myocardial injury/infarction is caused by lesions with ruptured plaques and/or those with a greater plaque burden (4). Virtual histology IVUS also has shown that post-PCI cardiac troponin (cTnT) elevation occurs in lesions with a large necrotic core area and positive remodeling (PR) of the vessel (5).. Multidetector computed tomography (MDCT) is a promising technique for noninvasive coronary angiography. With the development of MDCT, it is possible not only to detect coronary ...
A Nail in the Coffin of Troponin Measurements After Percutaneous Coronary Intervention | JACC: Journal of the American College...
Over the past several decades, we have made substantial progress in the early diagnosis and management of acute myocardial infarction (AMI). Throughout most of our careers, the diagnosis of AMI required that at least 2 of 3 criteria were met: prolonged ischemic symptoms, diagnostic electrocardiographic (ECG) changes, and elevation of total creatine kinase (CK) with creatine kinase-myocardial band (CK-MB) exceeding 3 times the upper limit of normal. Over the past several decades, these diagnostic criteria were repeatedly validated with evidence showing that the level of CK-MB was highly predictive of infarct size, development of heart failure, as well as short- and long-term mortality. Given these findings, why have many hospitals abandoned measurement of CK-MB in favor of troponin?. Unfortunately CK is present in other tissues, such as skeletal muscle or brain; thus the clinician used the % MB index and the typical rise and fall to determine the clinical significance of any CK elevation. It was ...

Results:. Of 69 patients with myocardial infarction, only 39% had diagnostic electrocardiographic ST-segment elevation. ST-segment elevation had a specificity of 99% and a positive predictive value of 93%. A relative lymphocytopenia (lymphocyte decrease ,20.3%) or elevated rapid creatine kinase-MB level (,4.7 ng/mL) was more sensitive than ST-segment elevation (sensitivities of 58% and 56%, respectively) but less specific (specificities of 91% and 93%, respectively). The presence of both a relative lymphocytopenia and an elevated rapid creatine kinase-MB level had a sensitivity of 44%, a specificity of 99.7%, and a positive predictive value of 97% (95% CI, 80% to 99%). Both a relative lymphocytopenia and an elevated rapid creatine kinase-MB level were independent (P , 0.001) predictors of infarction in patients without ST-segment elevation. If myocardial infarction was suspected by the presence of both abnormal markers or ST-segment elevation, the sensitivity for early diagnosis increased from ...
More Wuhan Data Confirm Cardiac Injury, COVID-19 Fatality Link | tctmd.com
On admission, most patients who died presented [with] abnormal laboratory results, such as higher leucocyte counts, neutrophil rate, and levels of aspartic transaminase, creatinine, C-reactive protein, and procalcitonin, Shi et al write. These patients also were more likely than survivors to have elevated levels of creatinine kinase-myocardial band (CK-MB), myohemoglobin, and N-terminal pro-B-type natriuretic peptide in addition to TnI. Those who died also were older, more often male, and more likely to have a comorbidity such as hypertension, diabetes, CAD, chronic renal failure, chronic heart disease, or cerebrovascular disease. The most common comorbidity was hypertension, which was noted in 30% of the study population.. Importantly, Shi and colleagues say that in the period from admission to death, cardiac indicators showed a dynamic change in the death group, especially in the levels of CK-MB and cardiac TnI.. In the second paper, published online May 8, 2020, ahead of print in the ...

BACKGROUND: Peak creatine kinase-MB (CK-MB) level is associated with clinical outcomes after acute myocardial infarction (AMI). However, the prognostic impact of time between balloon and peak CK-MB (BP-time) after percutaneous coronary intervention (PCI) is unclear. METHODS: This multicentral observational study initially included 1,354 AMI patients undergoing primary PCI within 24 hours after the onset between 2011-2016. After the exclusion of patients with unknown onset time of AMI, patients with the highest CK-MB at baseline, and patients without postPCI TIMI grade 3 flow, 954 patients were ultimately enrolled. They were divided into 4 groups by BP-time with 3-hour increment. The primary endpoint was all-cause mortality. RESULTS: Kaplan-Meier analysis showed that patients with BP-time,3-hours had the lowest, and with BP-time,9-hours had the highest mortality (at 3 years: 5.5% vs. 11.6%, Figure). Multivariate Cox regression analysis revealed that BP-time was an independent predictor of ...

Clinical implications of the Third Universal Definition of Myocardial Infarction | Heart
The definition of myocardial infarction (MI) continues to evolve as refined ECG criteria, more advanced imaging, and more sensitive and specific biomarkers are developed. The acceptance globally of a clinically practical standard definition for everyday practice would allow for better comparisons across clinical experiences and further facilitate research in this critical area. Because of the evolution of better diagnostic tools and more information about the value and limitations of previous definitions, there was a need to update the Universal Definition of MI published in 20071 and this has recently been accomplished.2 Great efforts were made by the taskforce that developed these guidelines to establish clinical criteria which correspond to the contemporary management of patients suspected of having MI. Therefore, a combination of clinical symptoms, cardiac biomarkers, and ECG changes indicative of myocardial ischaemia are central to the 2012 Third Universal Definition of MI. It stresses the ...
Ruptured Plaque Visualization by Noninvasive Coronary Computed Tomography Angiography | Circulation
A 69-year-old man presented with 2 weeks of exertional chest pressure typical of angina pectoris. An exercise stress test reproduced his symptoms and caused 1.5 mm of ST depression. Because a relative had a fatal event associated with invasive coronary angiography, he wished to have only noninvasive testing. Coronary computed tomographic (CT) angiography using 16-slice technology (Siemens Sensation 16) demonstrated a severe proximal left anterior descending artery lesion (Figure 1). A ruptured plaque was found with 14 Hounsfield units (HU) in one region and 60 HU in the remainder of this atheroma (Figure 2). The patient subsequently agreed to coronary angiography (Figure 3) and a stent was placed. This was complicated by transient slow flow and creatine kinase-MB elevation (110 IU). CT imaging demonstrating low HU suggests either thrombus or a lipid-laden lesion consistent with a ruptured vulnerable plaque. Its association with ruptured plaque thus identified the left anterior descending artery ...

OBJECTIVE--To compare the activity of plasminogen activator inhibitor (PAI-1) in diabetic and non-diabetic patients admitted with acute myocardial infarction and to determine whether PAI-1 activity influences reperfusion after thrombolytic therapy. DESIGN--Prospective study of patients admitted with acute myocardial infarction. SETTING--District general hospital. MAIN OUTCOME MEASURES--Reperfusion assessed by time to peak release of creatine kinase-MB isoenzyme. RESULTS--Baseline PAI-1 activity and antigen concentrations were significantly higher in diabetic patients (n = 45) than in non-diabetic patients (n = 110) (24.6 (6.9) v 18.6 (7.9) AU/ml (AU = arbitrary units) (p = 0.0001) and 58.8 (13.1-328.8) v 41.0 (10.9-125.4) ng/ml (p = 0.004). Time to peak release of creatine kinase-MB was calculated in 123 (80%) patients. In 98 who received thrombolytic therapy the median time to peak enzyme release was 15.5 h (7.5-24 h) in diabetic patients (n = 26) and 12 h (5-26 h) in non-diabetic patients (n = ...

Ischemia-Modified Albumin in Acute Stroke. - Plasma Protein Therapeutics Association (PPTA)
Background: Ischemia-modified albumin (IMA)is a new biological marker of ischemia. Previous studies have found increased serum IMA levels after myocardial ischemia, but no study has investigated the possibility that stroke modifies IMA blood levels.. Materials and Methods: We studied 118 consecutive patients presenting within 3 h of the onset of an acute neurological deficit [84 brain infarctions (BI), 18 brain hemorrhages (ICH) and 16 transient ischemic attacks lasting less than 1 h or epileptic seizures]. Serum samples were obtained for all patients at initial presentation and repeated only in patients with stroke at 6, 12 and 24 h. IMA was measured by the albumin-cobalt-binding test (Ischemia Technologies, Denver, Colo., USA). Results: The initial median IMA (bootstrap 95% confidence interval, CI) was 83 U/ml (79-86) and 86 U/ml (75-90) in patients with BI and ICH, respectively (p = 0.76), and was 73 U/ml (58-79) in others (p = 0.003 compared with BI, and p = 0.017 with ICH). Baseline IMA ...

The aim of this study is to evaluate the effect of pre PCI administration of intracoronary nitroprusside on post procedural myonecrosis. Myonecrosis is a prognostically important complication of PCI. Nitric oxide is a potent vasodilator in the resistance arteriolar circulation, and plays a significant role in the control of coronary blood flow through the microcirculation. nitroprussideis a direct donor of nitric oxide. A total of 62 patients were randomized into the NTP (n= 31) or control (n= 31) group. Patients who were scheduled for non-urgent PCI in de novo native coronary arteries were eligible. All patients were pretreated with statin, aspirin and clopidogrel. Myonecrosis was measured by CK-MB elevation 24 h after PCI. The NTP group received intracoronary NTP befor PCI, whereas the control group did not. All patients in NPT group received NTP for prevention of myonecrosis at a dose of at least 50 μg given intrcoronary through guiding catheter. 22 patients received 50μg,7 patients ...

Ischemia-modified albumin use as a prognostic factor in coronary bypass surgery | Journal of Cardiothoracic Surgery | Full Text
Various types of markers have been used so far in order to reveal myocardial perfusion defect. However, these markers usually appear in the necrosis phase or in the late stage. Having been the focus of various investigations recently, ischemia-modified albumin (IMA) is helpful in establishing diagnosis in the early stages of ischemia, before necrosis develops. 30 patients that underwent only coronary bypass surgery due to ischemic heart disease within a specific period of time have been included in the study. IMA levels were studied in the preoperative, intraoperative, and postoperative periods. The albumin cobalt binding assay was used for IMA determination. Hemodynamic parameters (atrial fibrillation, the need for inotropic support, ventricular arrhythmia) of the patients in the postoperative stage were evaluated. Intraoperative measurement values (mean ± SD) of IMA (0.67677 ± 0.09985) were statistically significantly higher than those in the preoperative (0.81516 ± 0.08894) and postoperative (0
A novel indicator of widespread endothelial damage and ischemia in diabetic patients: ischemia-modified albumin | AVESİS
Ischemia-modified albumin (IMA) is a novel marker of tissue ischemia. Nowadays, IMA is accepted as a marker of oxidative stress. In this study, we aimed at establishing an association between IMA and hyperglycemia, blood pressure, lipid parameters, microvascular complications, hsCRP, and microalbuminuria in type 2 diabetes patients without overt macrovascular disease and acute ischemia. Fifty type 2 diabetes mellitus patients without a history of macrovascular disease or end-stage renal disease were enrolled into the study. Age-matched 30 healthy individuals were also included in the study as a control group. Plasma IMA (0.329 +/- A 0.046 and 0.265 +/- A 0.045 AbsU; P < 0.0001) and hsCRP levels (0.51 +/- A 0.36 and 0.32 +/- A 0.17 mg/dl; P < 0.0001) were significantly higher in the diabetic group compared to healthy controls. IMA level was significantly correlated with hsCRP (r = 0.76; P < 0.0001), HbA1c (r = 0.72; P < 0.0001), microalbuminuria (r = 0.40; P = 0.004), systolic blood pressure (r = ...

CK-MB - 15-C7562-26 | Pointe Scientific
Following acute myocardial infarction, CK-MB activity increases significantly and this elevation is highly specific for the laboratory diagnosis of myocardial infarction. Although total CK activity usually increases following myocardial infarction, in some patients only the CK-MB activity increases, while the total CK remains in the normal range. In this procedure CK activity is measured in the presence of an antibody to CK-M monomer. This antibody completely inhibits the activity of CK-MM and half of the activity of CK-MB, while not affecting the B subunit activity of CK-MB and CK-BB. Due to negligible concentrations of CK-BB in the circulation, the remaining activity, multiplied by a factor of 2, represents the activity of the CK-MB isoenzyme ...

Everyday E(B)M: EKG challenge #2 Resolution - Sometimes You are Anxious because You are Going to Die
We are classically taught to activate the cath lab for patients with STEMI or new LBBB. Given the unreliability/lack of specificity of new LBBB for diagnosis of myocardial infarction, it has been removed as a hard criteria for cath lab activation in the latest iteration (2013) of AHA/ACCF guidelines (Ref 4). The current Universal Definition of acute Myocardial infarction is: new ST elevation at the J point in at least 2 contiguous leads of 2 mm (0.2 mV) in men or 1.5 mm (0.15 mV) in women in leads V2-V3 and/or of 1 mm (0.1mV) in other contiguous chest leads or the limb leads. According to the AHA, New or presumably new LBBB has been considered a STEMI equivalent. Most cases of LBBB at time of presentation, however, are not known to be old because of prior electrocardiogram (ECG) is not available for comparison. New or presumably new LBBB at presentation occurs infrequently, may interfere with ST-elevation analysis, and should not be considered diagnostic of acute myocardial infarction (MI) ...
