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...

Fifty consecutive patients, 25 undergoing aortic valve replacement and 25 mitral valve replacement, were studied by serial electrocardiography, preoperative and postoperative technetium-99m pyrophosphate radionuclide scanning, and serial measurement of enzymes (creatine kinase, aspartate aminotransferase, urea stable lactic dehydrogenase) and the MB isoenzyme of creatine kinase to define the in...

The present study was designed to evaluate the effect of quercetin on myocardial oxidative stress and immunity function impairment induced by isoproterenol in rats. To induce myocardial ischemia, Wistar rats were subcutaneously injected with isoproterenol (70 mg/kg). Blood immunity index, cardiac marker enzymes and antioxidative parameters in hearts were measured. It was found that the levels o...

Twice-daily CPK-MB determinations were performed but not made availabe to the physicians of 179 consecutive patients with precordial pain admitted to a community hospital to evaluate the diagnostic importance of this isoenzyme. Physician decision was based upon history and once-daily ECG and total enzymes (CPK, SGOT, LDH). Following hospital discharge, each patient's clinical record was reviewe...

Though there are studies to show protective effect of glutathione against neurotoxicity and nephrotoxicity, the present study was designed to investigate the cardio protective effect of glutathione against isoproterenol induced myocardial infarction in rats by demonstrating the changes in serum cardiac markers, antioxidant enzymes and ECG changes. Wistar male rats were randomly divided into fou...

Little is known about the vascular and metabolic adaptations that take place in the fetal heart to maintain cardiac function in response to increased load. Chronic fetal anemia has previously been shown to result in increased ventricular mass, increased myocardial vascularization, and increased myocardial expression of hypoxia-inducible factor-1 (HIF-1) and vascular endothelial growth factor (V...
