Background & Aims: Significant left main coronary artery disease (LMCAD) is found in 3 to 6 percent of all patients who undergo coronary arteriography. LMCAD usually requires an emergent surgery that has a higher rate of mortality and complications. The risk factors of left main involvement in previous studies are controversial. The aim of this study was to determine the traditional risk factor...

INTRODUCTION AND OBJECTIVES Coronary ectasia is characterized by the presence of diffuse dilation of the coronary vessels and is detected in 0.3-5.3% of angiographic studies. Our objective was to evaluate the prevalence of this condition, to analyze its clinical and angiographic characteristics, and to compare patients with ectasia and patients without it. PATIENTS AND METHOD Coronary angiogr...

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...

BACKGROUND AND OBJECTIVES It has been demonstrated that the anomalous origin of coronary arteries (AOCA) are generally asymptomatic and rare diseases. However, some cases can cause severe life threatening events. To detect these anomalies, coronary angiographies and autopsies were used to detect coronary artery anomalies, but these procedures have limitations because of their invasiveness. The ...

BACKGROUND Mitral annular calcification has been associated with various systemic and cardiac diseases, with a higher prevalence in women and patients over 70. A possible association between mitral annular calcification and coronary artery disease has recently been suggested. OBJECTIVE To determine the prevalence of severe coronary artery disease in younger patients with mitral annular calcif...

conclusion primary and secondary prevention of cad including life style modifications and dietary interventions strongly recommended in iranian population. results the prevalence of cad, coronary risk factors and metabolic syndrome in iran is higher than western countries and similar to some middle east countries. there are limited data with regard to novel coronary risk factors in iran. method...

Background: A single coronary artery (SCA) is a rare anomaly encountered using conventional angiography. right (RCA) originating from left anterior descending (LAD) subtype of SCA. Only few cases are described in published literature. Case presentation: We this 55-year-old male who presented with angina pectoris. The anomalous RCA was suspected by angiogram and confirmed computed tomography (CT...

INTRODUCTION The correlation between erectile dysfunction (ED) and coronary artery disease has been emphasized and ED has been recognized as a potential independent risk factor and/or predictor of coronary artery disease (CAD). We evaluated the association between the number of occluded coronary arteries in myocardial infarction (MI) patients with the severity of ED, and investigated the influe...

spontaneous coronary artery dissection (scad) is a rare and important cause of acute coronary syndrome and sudden cardiac death. various etiologies are thought to be responsible for this condition, among which underlying atherosclerosis seems to be the most common. scad is predominant in women and is usually diagnosed via coronary artery angiography. therapeutic interventions include medical th...
