In this study, we investigated the cardioprotective effects of resveratrol. Rats were intraperitoneally administered with resveratrol (25 mg/kg bw) or vehicle (ethanol 10%) for 7 days and their heart subjected to ischemia/reperfusion injury. Isolated hearts were langendorff perfused, left ventricular functions as heart rate and developed pressure, as well as, heart antioxidant status were deter...

OBJECTIVE To examine the association of myocardial infarction and stroke incidence with several commonly used two drug antihypertensive treatment regimens. Design Population based case-control study. Setting Group Health Cooperative, Seattle, WA, USA. PARTICIPANTS Cases (n=353) were aged 30-79 years, had pharmacologically treated hypertension, and were diagnosed with a first fatal or non-fata...

The levels of creatine kinase, hydroxybutyric dehydrogenase, and aspartate transaminase have been serially measured in the serum of patients undergoing surgery. Serum enzyme levels often rose to a range commonly found after myocardial infarction but fell to normal within 5-10 days. Raised serum enzyme levels have no diagnostic significance in a case of postoperative chest pain until after the f...

The effect of propranolol (0.1 mg/kg intravenously followed by 320 mg given over 27 hour orally) on serum levels of creatine kinase enzyme was studied in a randomized trial involving 95 patients seen within 12 hours of onset of symptoms of uncomplicated myocardial infarction. In 15 patients who were treated with propranolol within 4 hours of onset, and who eventually developed pathological Q wa...

introduction: the aim of the present study was to evaluate the effect of exercise training and l-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (mi). methods: four weeks after the surgically-induced mi, 40 male wistar rats were randomly assigned to the following 4 groups (n=10): mi-sedentary control (sed) mi-exercise (ex) mi-sed...

In the present study, the effect of initial body temperature changes on myocardial enzyme levels and cardiac function in acute myocardial infarction (AMI) patients was investigated. A total of 315 AMI patients were enrolled and the mean temperature was calculated based on their body temperature within 24 h of admission to hospital. The patients were divided into four groups according to their n...

Cholinesterase and succinyldehydrogenase activity of surgically removed left atrial auricles from patients in atrial fibrillation and in sinus rhythm have been compared, using histochemical methods. Higher cholinesterase and lower succinyldehydrogenase activity has been found in atrial fibrillation than in sinus rhythm. The pulmonary capillary mean pressure of patients with atrial fibrillation ...
