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...

OBJECTIVE To investigate whether women presenting with suspected angina would show less severe coronary artery disease in than men as determined by the extent score. METHODS We examined 994 participants of the Australian Heart Eye Study presenting for coronary angiography in the investigation of chest pain from June 2009 to February 2012. People were excluded if there was a history of coronar...

Background: Coronary angiography consists of the selective injection of contrast agents in coronary arteries. Optimal strategy for heparin administration during coronary angiography has yet to be determined. We assessed the effect of heparin administration during coronary angiography on vascular, hemorrhagic, and ischemic complications.Methods: Five hundred candiates for diagnostic coronary ang...

Objectives Coronary artery anomalies are uncommon, but important cardiac malformations, representing the second commonest cause of death in young athletes. Methods We utilized computerized tomographic angiography to screen and precisely delineate coronary artery anomalies in patients with minimal cardiac symptoms. Results During 3.5-year period, we performed 2888 computerized tomographic an...

OBJECTIVES The purpose of this study was to examine sex-specific associations, if any, between per-vessel coronary artery disease (CAD) extent and the risk of major adverse cardiovascular events (MACE) over a 5-year study duration. BACKGROUND The presence and extent of CAD diagnosed by coronary computed tomography angiography (CTA) is associated with increased short-term mortality and MACE. N...

A 65 year-old woman was admitted to our hospital, because of unconsciousness after chest and back pain. Echocardiography showed pericardial effusion. She suffered from pre-shock due to cardiac tamponade. Although a cause of cardiac tamponade was unclear, we performed emergency surgical treatment without coronary angiography. In operation, we found a rupture of coronary arteriovenous fistula and...

Congenital coronary artery anomalies are sporadically discovered in patients undergoing coronary angiography and in autopsy series. Although most anomalies are clinically insignificant, some may become causes of cardiovascular morbidities and mortality. Diagnosis is commonly made with conventional coronary artery angiography. The current development of modern cardiac computed tomography allows ...

OBJECTIVES The aim of this project was to assess the utility of dobutamine stress echocardiography (DSE) for evaluation of women with suspected ischemic heart disease. BACKGROUND Most investigations addressing efficacy of diagnosis and treatment of coronary artery disease (CAD) have been performed in predominantly male populations. As part of the Women's Ischemia Syndrome Evaluation (WISE) st...

BACKGROUND As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative for evaluation of coronary anatomy with a lower referral threshold than invasive coronary angiography (ICA), the prevalence of coronary anomalies in CCTA may more closely reflect the true prevalence in the general population. Morphological features of coronary anomalies can be evaluated more ...

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,...
