Diagnosis of myocardial infarction is very important in a patient with chest pain. Chest pain is not always present or it may be from other causes rather than myocardial infarction. Q wave is present in 30] of infarction. ST,T wave changes are present in all myocardial infarctions, but these changes also are present in myocardial ischernia.  For these reasons diagnosis of myocardial infarction...

objective(s):the objective of this study was to investigate the interaction of daunorubicin (dnr) and cardiac myosin (cm) and the changes in mice hearts to exhibit dnr-induced cardiotoxicity . materials and methods:the interaction between dnr and cm was expressed using fluorescence quenching at ph 4.0-9.0 and 15-37 °c. dnr-induced cardiotoxicity was studied using in vivo experiment.  forty grou...

Objective(s): Reperfusion of ischaemic myocardium results in reduced nitric oxide (NO) biosynthesis by endothelial nitric oxide synthase (eNOS) leading to endothelial dysfunction and subsequent tissue damage. Impaired NO biosynthesis may be partly due to increased levels of asymmetrical dimethylarginine (ADMA), an endogenous inhibitor of eNOS. As dimethylarginine dimet...

Background: Calcium overload and free radical mediated damage in the mitochondria is the most important pathological changes associated with myocardial ischemic-reperfusion injury. The verapamil post-treatment has been previously reported to prevent reperfusion-induced myocardial injury but functional recovery may be delayed due to the drug's inherent direct myocardial depression effect. In the...

Angiotensin-Converting Enzyme Inhibitors (ACEI) are commonly used to prevent cardiac remodeling in patients with ST-Segment Elevation Myocardial Infarction (STEMI).

To determine the presence of anticardiolipin (aCL) antibodies in patients with ischemic events, we designed a case-control study. We studied 33 patients with unstable angina, 33 male patients with myocardial infarction and 34 control subjects with no evidence of ischemic heart disease. Plasma samples were assessed for IgG anticardiolipin antibodies by enzyme-linked immunosorbent assay (ELI...

The activity of alpha-hydroxybutyrate dehydrogenase, creatine kinase, creatine kinase MB and aspartate aminotransferase was measured on serial plasma samples from patients with acute myocardial infarction. The study was part of a multicentre randomised trial of the effect of thrombolytic treatment in the acute phase of acute myocardial infarction. The applicability and comparability of enzyme t...

to determine the presence of anticardiolipin (acl) antibodies in patients with ischemic events, we designed a case-control study. we studied 33 patients with unstable angina, 33 male patients with myocardial infarction and 34 control subjects with no evidence of ischemic heart disease. plasma samples were assessed for igg anticardiolipin antibodies by enzyme-linked immunosorbent assay (elisa). ...
