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 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)
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)
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)
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)
Mitral regurgitation (MR) is a common valvular lesion in the general population with considerable impact on mortality and morbidity. The MitraClip System (Abbot Laboratories, Abbot Park, IL, USA) is a novel percutaneous approach for treating MR which involves mechanical edge-to-edge coaptation of the mitral leaflets. We present our initial experience with(More)
There have been attempts to find new approaches to the treatment of multivessel coronary artery disease without increasing adverse events. Deployment of drug-eluting stents (DES) for complex lesions and bare-metal stents (BMS) for simpler lesions, although already in wide use, has not been well supported by clinical study. A cohort of 1,658 patients who(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)
