Coronary heart disease (CAD) is the leading cause of death specially among elderly. Coronary angiography is the best diagnostic method in the patients, but is unfortunately an invasive procedure with its inherent risks. Myocardial perfusion scan is a noninvasive and sensitive method for evaluation of CAD and is suggested by many investigators in recent years. In this study, 64 patients wh...

Introduction: Coronary artery disease secondary to atherosclerosis is the most common cause of mortality. Coronary angiography is the most precise method for determining the extent of disease in the coronary vascular bed. Arterial stiffness has been proposed as a marker of atherosclerosis in some studies. One of the noninvasive methods for the determination of arterial stiffness is Doppler echo...

introduction: the precise time of using percutaneous coronary intervention (pci) after fibrinolytic therapy for maximum efficiency and minimum side effects is still undetermined. therefore, the present study was designed to compare the outcome of myocardial infarction (mi) patients who underwent surgical intervention (angiography and pci) within 48 hours of thrombolytic therapy or after that. m...

coronary artery calcium scoring (cacs) is a reasonable test for patients with the possibility of atherosclerosis. it can also be used for reclassifying the coronary artery disease (cad) to the high-risk status by higher cacs and subsequently modifying the management of the patients.the purpose of this study was to investigate the association of cacs to the severity of coronary artery disease in...

background: coronary computed tomography angiography (ccta) is a well-known method for evaluating anatomic coronary stenosis, but the reliability of ccta to predict cardiovascular events is an issue of controversy. materials and methods: in this prospective observational study, 58 patients with acute chest pain and low-to-moderate risk were selected and ccta was performed on them. during follow...

background and objectives: studies have shown that patients awaiting coronary angiography (ca) are often anxious. high level of anxiety can lead to physical and psychological stress with adverse effects on organs, es­pecially heart. there is limited information on state and trait anxiety level in these patients in the literature. this study was thus designed to investigate the level of these tw...

a 73-year-old woman who had undergone coronary artery bypass grafting for coronary artery stenosis six years ago, presented with right lower extremity claudication. angiography revealed right external artery stenosis. elective external iliac ptca was performed complicated with simultaneous external iliac artery and vein rupture that was an exceedingly rare event. retroperitoneal laparotomy with...

tissue level myocardial perfusion is one of the most important prognostic factors after successful recanalisation of the occluded coronary artery in patients suffering acute st elevation myocardial infarction (stemi). the primary objective of the present study was to examine the relationship between videodensitometric myocardial perfusion parameters as assessed on coronary angiograms directly f...
