Coronary heart disease (CHD) is the leading cause of mortality worldwide. One main contributions and morbidity in CHD patients acute myocardial infarction (AMI), which result abrupt occlusion an epicardial coronary artery due to a sudden rupture atherosclerotic plaque, causing ischemia. In initial stage ischemia, lack oxygen nutrient supply results biochemical metabolic changes within myocardiu...

background and objectives:  helicobacter pylori cause a chronic gastric infection, and may cause extra gastrointestinal disease. the association between h. pylori infection and serum lipid profiles is still controversial. the aim of this study was to investigate any possible relationship between h. pylori infection and lipid levels. materials and methods: the subjects were 400 volunteer referr...

background: conducted researches show that psychological factors may have a very important role in the etiology, continuity and consequences of coronary heart diseases. this study has drawn the psychological risk and protective factors and their effects in patients with coronary heart diseases (chd) in a structural model. it aims to determine the structural relations betweenpsychological risk a...

OBJECTIVE To determine whether isometric exercise increases collateral flow in remote ischaemic myocardium in acute coronary occlusion models of patients with coronary artery disease. DESIGN A randomized controlled study. SUBJECTS Sixty-five patients with 1-vessel coronary artery disease. METHODS Subjects were randomly assigned to either the isometric exercise group or non-exercise group....

The data from this study document that dobutamine is a powerful inotropic agent in anesthetized dogs with acute myocardial ischemia and in awake, unsedated ones with chronic myocardial infarction. Dobutamine significantly increases heart rate at relatively small doses in anesthetized dogs with acute myocardial ischemia but considerably larger amounts of dobutamine are required to significantly ...

A detailed pathological study of the coronary arteries was carried out on 130 random white subjects (91 male and 39 female) who died suddenly in the Glasgow area. In 30 there was a clearly defined cause of death that was not due to ischaemic heart disease. In eight subjects the cause of death was in doubt. Ninety two of the 130 showed coronary stenosis resulting in a loss of more than 75% of co...

Myocardial infarction occurring in young people with angiographically normal coronary arteries is well described but the pathophysiology of this condition remains unknown. Coronary artery spasm in association with thrombus formation and minimal atheromatous disease or spontaneous coronary artery dissection are possible causes. Two young men presented with severe chest pain after acute alcohol i...

OBJECTIVES Scientific literature indicates that the risk of coronary heart disease morbidity and death among peritoneal dialysis patients exceeds risk observed in non-renal patients. The aims of this study were to establish the independent predictors associated with increased risk of coronary heart disease in peritoneal dialysis patients without diabetic nephropathy. MATERIALS AND METHODS A n...

Myeloproliferative disorders (MPDs) are defined as clonal stem cell diseases. the cardiovascular system is involved in 4 to 21% of MPD cases, presenting as acute ischemic coronary artery disease, valvular heart involvement, pericardial involvement, aortitis, thrombosis of major vessels, pulmonary embolism, systemic and pulmonary hypertension. Acute coronary syndrome may be the first manifestati...

INTRODUCTION Acute coronary syndrome is the major leading cause for coronary care unit admission. Its spectrum comprises a variety of disorders including unstable angina, non ST elevation and ST elevation myocardial infarction. Its spectrum and incidence is crucial as a part of need assessment of cardiac catheterization laboratories. METHODS An observational study was designed to study the sp...
