AIM To evaluate the association between the preprocedural hemoglobin (Hb) level and 1 year major adverse cardiac event (MACE) in patients undergoing percutaneous coronary intervention (PCI). METHODS A total of 2819 patients (mean age 56.61 ± 10.37 years, 69% male) with available preprocedural Hb levels were included. Patients were followed up for 12(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)
BACKGROUND Drug-eluting stents improved the outcome after percutaneous coronary intervention (PCI), however, there may be significant differences in their safety and efficacy. AIM To compare the in-hospital and mid-term clinical outcomes of stenting with sirolimus-eluting stents (SES) versus paclitaxel-eluting stents (PES) for the treatment of coronary(More)
In this retrospective study, we compared the in-hospital and long-term outcomes of the on-label and off-label uses of drug-eluting stents.From April 2003 through June 2007, 1,538 patients underwent percutaneous coronary intervention with a drug-eluting stent (sirolimus or paclitaxel) at Tehran Heart Center. Off-label implantation of the drug-eluting stent(More)
OBJECTIVE In this case-match study, we evaluated the impact of the CYP2C19*2 polymorphism in the occurrence of in-stent restenosis during a 1-year follow-up period despite adequate dual anti-platelet therapy in Iranian patients having undergone percutaneous coronary intervention (PCI). METHODS This study, conducted at a tertiary referral heart center in(More)
BACKGROUND This study was designed to compare the frequency of conventional cardiovascular disease risk factors and clinical biochemistry profile in patients with cardiac syndrome X (CSX) and obstructive coronary artery disease (CAD). METHODS A cross-sectional study was conducted on patients with typical angina and positive exercise tolerance test(More)
BACKGROUND This prospective study aimed to evaluate the detailed outcomes of diabetic patients with critical limb ischemia, six months after percutaneous transluminal angioplasty and appropriate multidisciplinary wound care.  METHODS Totally, 45 consecutive patients (50 limbs) were enrolled and then divided into two groups according to the healing of(More)
OBJECTIVES The SYNTAX score is a grading system that evaluates the complexity and prognosis of patients undergoing percutaneous coronary intervention (PCI). We investigated the association between the incidence of major adverse cardiac events (MACE) following PCI and the SYNTAX score in patients with three-vessel disease. METHODS We consecutively enrolled(More)
We compared outcomes of percutaneous coronary intervention patients who received biodegradable-polymer biolimus-eluting stents with those who received durable-polymer everolimus-eluting stents. At Tehran Heart Center, we performed a retrospective analysis of the data from January 2007 through December 2011 on 3,270 consecutive patients with coronary artery(More)
BACKGROUND We performed this study to evaluate the possible synergism between hypertension and other conventional risk factors of coronary artery disease (CAD) on an angiographic severity of coronary atherosclerosis. METHODS A cross-sectional study was conducted on 10502 consecutive patients who underwent coronary angiography in the cardiac(More)
