Abstract Familial hypercholesterolemia (FH) is a hereditary dislipidemia. Patients present with extremely high level of low-density lipoprotein cholesterol (LDL-C), which is due to mutation in the gene of LDL receptor. Homozygous patients (HoFH) whose incidence is 1 in 1.000.000 are at high risk of premature aortic valve stenosis, and coronary artery atherosclerosis. In homozygous individual...
Introduction: Doppler ultrasonography (DUS) is the most preferable method for screening of carotid artery disease in patients undergoing CABG. The purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...
Introduction: Myocardial bridging is a congenital condition in which a segment of a major epicardial coronary artery has an intra myocardial route. Myocardial bridging is usually confined to a single vessel and is typically the mid segment of the left anterior descending artery. Bridging may be associated with chest pain, myocardial infarction, and sudden cardiac death, or usually asymptomati...
Abstract Background: Coronary artery disease, (CAD) is an important risk for morbidity and mortality. Because of controversial reports about relation between high-sensitivity C-reactive protein (hs-CRP) level and the severity of coronary artery stenosis, this study was done in Taleghani Hospital. Methods: In this case-control study 85 patients with CAD undergoing coronary angiography were ...
Background: Coronary artery stenosis is one of the atherosclerotic complications which can lead to decreased oxygen supply in heart tissue and heart attack. rs1050450 Polymorphism is one of polymorphisms in GPx1 gene that may change its antioxidant activity. Furthermore, two polymorphisms of NADPH Oxidase, rs4673 and rs13306294, are suggested to have a role in the function of this enzyme. In th...
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: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...

aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. the most common cause of coronary artery aneurysms is atherosclerosis. angiography is the gold standard for diagnosis and treatment. depending on the severity of the coexisting coronary stenosis, patients with left main co...
Background and purpose: Coronary artery stenosis is a progressive process associated with artery calcification. Although the role of matrix Gla protein (MGP) is not completely clear but its expression in vascular smooth muscle cells (VSMCs) and sub-endothelial macrophages suggests a role in vascular calcification. The rs1800799 is one of the polymorphisms oriented within transcription factor el...
