AIMS We sought to perform a systematic review and meta-analysis to evaluate the potential factors affecting ischaemic postconditioning (IPoC) for patients with ST-segment elevation acute myocardial infarction (STEMI) in primary percutaneous coronary intervention (PCI). METHODS AND RESULTS Ten randomized controlled trials (RCTs) on IPoC reporting myocardial enzyme levels or left ventricular ej...

INTRODUCTION Acute myocardial infarction (AMI) is still one of the most common causes of death worldwide. In recent years, for diagnosis of myocardial ischemia, a new parameter, called ischemia modified albumin (IMA), which is thought to be more advantageous than common methods, has been researched. AIM In this study, systematic analysis of parameters considered to be related to myocardial is...

Platelet aggregation, at the site of an atherosclerotic plaque in the coronary arteries has been recognized as a crucial step in the pathogenesis of unstable angina and myocardial infarction. As part of current medical therapy in patients with unstable angina, evolving myocardial infarction and in patients undergoing coronary intervention, platelet aggregation is inhibited partly by administrat...

Comparisons were made between enzymic indices of myocardial infarct size (total creatine kinase appearance and peak enzyme activity) measured during the acute state of a first myocardial infarct in 32 male patients, and analysis of contraction abnormalities in biplane left ventricular cineangiocardiograms performed one month later. The cineangiocardiograms were analysed independently by two rad...

BACKGROUND Peroxisome proliferator-activated receptor-alpha (PPAR-alpha) is expressed in the heart and regulates genes involved in myocardial fatty acid oxidation (FAO). The role of PPAR-alpha in acute ischemia/reperfusion myocardial injury remains unclear. METHODS AND RESULTS The coronary arteries of male mice were ligated for 30 minutes. After reperfusion for 24 hours, ischemic and infarct ...

Introduction: Inhibition of renin angiotensin system represents an important approach in the management of cardiovascular diseases. The aim of this study was to explore the effects of pretreatment with non-hypotensive dose of angiotensin converting enzyme (ACE) inhibitor, ramiprilat and angiotensin type 1 (AT1) receptor blocker, losartan on myocardial infarct size and arrhythmias in a rat mo...

AIM Estrogens regulate several biological processes involved in the pathogenesis of myocardial infarction. Catechol-O-methyltransferase (COMT) is a key enzyme in the degradation of estrogens. There is a functional polymorphism in the COMT gene (Val158Met), affecting the activity of the enzyme. We investigated if the low activity genotype of COMT is associated with an altered risk of myocardial ...

To investigate the effects of different doses of abnormal Savda Munziq on myocardial ischemia-reperfusion injury (MI/RI) in rats with the abnormal Savda syndrome, 50 abnormal Savda animal models were randomly divided into a control group, a model group, a high-dose group, a middle-dose group, and a low-dose group, with each group containing 10 rats. The enzyme-linked immunosorbent assay was use...
