Objectives To develop prediction models that better estimate the pretest probability of coronary artery disease in low prevalence populations. Design Retrospective pooled analysis of individual patient data. Setting 18 hospitals in Europe and the United States. ParticipantsPatients with stable chest pain without evidence for previous coronary artery disease, if they were referred for computed t...
Background and Aim: Despite the information regarding CAD risk factors, there isn't agreement between the relation of this risk factors and coronary artery diseases. This study was done for determination of related factors with vessels involved in coronary artery angiography. Materials and Methods: In this descriptive and analytical study, 2390 patients' .were selected via census sampling from...
Background and Objectives: Cardiovascular disease is the most common cause of death in developed countries. In addition to traditional risk factors for cardiovascular disease, nowadays, accumulating evidence indicates that a variety of infections contribute to pathogenesis of atherosclerosis, (We investigated whether Helicobacter pylori infection is related to Prevalence of coronar...
Background: Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein with inhibitory effects on the formation of plasmin from plasminogen by plasminogen activator. Thus, it prevents clot lysis in vessel walls. Several evidences prove the relationship between coronary artery disease and response to fibrinolytic therapy in patients with myocardial infarction with PAI-1 level. Opium addiction i...
Background. Congenital anomalies of the coronary arteries are a cause of sudden cardiac death. Of the known anatomic variants, anomalous origination of a coronary artery from an opposite sinus of Valsalva (ACAOS) remains the main focus of debate. Case Series. We present three cases, all presenting to our facility within one week's time, of patients with newly discovered anomalous origination of...
Among 12,720 patients subjected to coronary angiography because of clinical suspicion of coronary heart disease, 2,234 (78% men and 22% women) were free from major modifiable coronary risk factors. They did not report alcohol consumption, use of antiplatelet or lipid lowering agents, oral contraceptives or sex hormones; there was no history of bilateral oophorectomy, smoking, diabetes mellitus,...
Background: The association between coronary angiographic findings and the level of anxiety symptoms among patients who undergo coronary angiography is not known. The aim of this study was to investigate the association between the extent of coronary stenosis and anxiety symptoms in patients who undergo coronary angiography. Methods: In a cross-sectional study, 106 patients who underwent corona...
Congenital anomalies of the coronary artery causing coronary occlusive disease may be of many different types. A 67-year-old woman with no coronary risk factors was referred for coronary angiography with few months' history of angina. The patient underwent coronary angiography due to ischemic cardiac symptoms with nondiagnostic exercising test. In coronary angiography, the left main coronary ar...
Background: The aim of this study was to assess the relationship between hypertension and aldosterone-renin ratio (ARR) with the severity of coronary artery disease (CAD). Methods: This cross-sectional study was performed on non-diabetic patients who were candidate for coronary angiography in Shafa hospital in Kerman in 2017. The levels of active renin and ald...
OBJECTIVES We investigated the association of the intron 4 polymorphism of the endothelial nitric oxide synthase (eNOS) gene with coronary artery disease (CAD). BACKGROUND Genetic alterations in the gene encoding for eNOS could contribute to the development and progression of CAD. METHODS We genotyped for the eNOS intron 4 polymorphism in 194 subjects undergoing coronary angiography. Genoty...
