To investigate a possible association of ABO blood groups with coronary artery disease in well-documented patients, we designed a cross-sectional study of 2026 patients, known case of coronary artery disease in angiography, who underwent coronary artery bypass graft at Tehran Heart Center, with regard to coronary artery disease major risk factors as well as(More)
Background: The effects of opium dependence on prognosis and short term outcome of patients with acute myocardial infarction (AMI) are not clear yet. Methods: From March 2004 to August 2004 all male patients admitted with diagnosis of AMI were enrolled. Patients who fulfilled DSM-IV-TR criteria were chosen as opium dependent patients (ODP). Demographic(More)
BACKGROUND Specific infectious agents have been found to be related to the pathogenesis of coronary atherosclerosis. AIMS We assessed the possible association between angiographically proven coronary artery disease (CAD) and hepatitis B surface antibody (HBS Ab) seropositivity in a population with relatively high prevalence of hepatitis B virus (HBV)(More)
Estrogen is established to influence lipoprotein metabolism and inflammatory markers. Alternations in estrogen receptor alpha (ESR1) expression and function may affect the role of estrogen in this regard. The aim of this study was to determine whether ESR1 PvuII and XbaI gene polymorphisms have effects on lipoprotein (a) as well as inflammatory variables in(More)
BACKGROUND There is controversy about the prophylactic measures proposed for the prevention of contrast-induced nephropathy (CIN). We aim to compare the efficacy of the combination of sodium bicarbonate and isotonic saline and that of isotonic saline alone in preventing CIN. STUDY DESIGN Randomized double-blind controlled trial. SETTING & PARTICIPANTS(More)
AIMS To determine the association between glycated hemoglobin (HbA1c) and angiographically proven coronary artery disease (CAD) and its severity in nondiabetic individuals. METHODS We enrolled 299 consecutive individuals undergoing coronary angiography for suspected ischemia. Patients were included if they had no history of prior revascularization or(More)
The association between coronary arterial dominance patterns and the coronary artery diameter, length, and valvular heart diseases were previously studied. However, its association with coronary artery disease (CAD) is unclear. We investigated to determine whether the extent and localization of CAD differ in right, left, or codominant coronary arterial(More)
OBJECTIVES To examine the relationship between PvuII and XbaI polymorphisms, with the presence of angiographically determined CAD in an Iranian population. DESIGN AND METHODS Patients having angiographic evidence of atherosclerosis (Gensini score > 6) in their epicardial coronary tree (CAD(+) case group) were compared with Patients with Gensini score < or(More)
OBJECTIVES To investigate the correlation between serum lipoprotein(a) concentration and existence as well as severity of coronary atherosclerosis. DESIGN AND METHODS A cross-sectional study was conducted on 826 patients who underwent angiography through measuring blood sugar, serum lipids, lipoprotein(a) and evaluation of coronary stenosis by Gensini(More)
BACKGROUND Clinical trials of revascularization have routinely under-enrolled elderly subjects. Thus, symptom relief and improved survival might not apply to elderly patients, in whom the risk of mortality and disability from revascularization procedures seems to be high and co-morbidity is more prevalent. The present case control study was performed to(More)
