background: coronary artery bypass grafting surgery (cabg) and precutaneous transluminal coronary intervention (pci) are safe and effective in the treatment of coronary artery disease. the aim of this study was to determine and compare anxiety, self efficacy expectation and perceived social support between cabg patients and pci patients referral to receiving cardiac rehabilitation programs. m...

Background: Left main coronary artery (LMCA) stenosis is a leading cause of mortality and morbidity in many countries. Metabolic syndrome (MS) is a risk factor for coronary artery disease (CAD). The effects of MS on left main coronary artery stenosis are not well-defined. The aim of this study was to examine the effects of MS on left main coronary artery stenosis.Methods: A total number of 495 ...
Introduction: Although coronary endarterectomy is not an ideal procedure, it is the only available option for cardiac surgeons in some patients with diffuse coronary artery disease. Based on the majority of conducted studies, the results of coronary endarterectomy (including survival, graft patency, and recurrence of the symptoms of myocardial ischemia) are less prevalent than standard coronary...
conclusion we conclude that coronary calcium scoring provided useful information in the management of patients. in cacs less than 100, it has a npv of 87% in excluding significant stenosis in patients with the risk of cad but it does not have enough diagnostic accuracy for surely excluding coronary stenosis, so we should perform a combination of cacs and coronary ct angiography for patients. re...
This study evaluated the relationship between the location of the most severe coronary artery stenosis and the subsequent acute myocardial infarction (AMI). Methods: Of 1590 patients who were admitted with a diagnosis of AMI, we identified 44 patients who had undergone previous myocardial perfusion SPECT. Thirty-one of these patients also had previous coronary angiography. The relationshi...
Background and Objective: Ischemic heart disease implies reduction of oxygen and blood supply in the myocardium. The most common cause of ischemia is atherosclerotic coronary artery disease. While numerous risk factors lead to coronary diseases, the mechanism of infectious agents in CAD remains unidentified. Materials and Methods: In this study, 360 patients with and without coronary disease...
Background and purpose: Nowadays cardiovascular developments in pumping of heart-lung and improvements in anesthesia care, including intubation, have made early surgical intervention possible to correct life-threatening congenital anatomic abnormalities in patients of lower ages. This study was performed to evaluate the coronary artery patterns in neonates with transposition of the great arteri...
Introduction: Renal artery stenosis is the most prevalent disease of renal artery and has an important role in making hypertension and renal atrophy. Since in previous researches, despite high frequency of risk of cardiovascular disease in Iran, there did not exist any general research investigating risk factors of coronary artery disease and incidence of contemporary renal artery stenisis, ...
background: a good animal model for coronary surgery experiments has been difficult to establish. an ideal model should have the closest morphological resemblance to human beings. the objective of this study is to establish sheep as a model for these experiments. methods: the anatomical aspects of left anterior descending coronary artery (lad) and right internal thoracic artery (rita) in the sh...
