BACKGROUND The purpose of this study was to determine the factors which can help to predict operative mortality before performing the operation, and afterwards. METHODS The study population consisted of 504 patients (91 women and 413 men) who underwent primary isolated coronary artery bypass surgery from December 1997 to September 1999 by the same surgeon(More)
PURPOSE The aim of this study was to identify determinants of long-term results after coronary artery bypass surgery (CABG) in group of Iranian patients with systolic left ventricular (LV) dysfunction. METHODS Reduced LV function was defined as an LV ejection fraction of <30%. Using our surgery database, we randomly selected 110 patients with EF < 30% and(More)
BACKGROUND Hyperhomocysteinemia is known as an independent risk factor of atherosclerosis, but the probable role of hyperhomocysteinemia in premature Coronary Artery Disease (CAD) is not well studied. The aim of this study was to assess the role of hyperhomocysteinemia, folate and Vitamin B12 deficiency in the development of premature CAD. METHODS We(More)
The decision to proceed with triple-valve surgery should take into account reasonable estimates of the risk of the surgery and of the potential benefit to be gained. In the present study, we reviewed our experience with triple-valve surgery, focusing on short-term death and morbidity, mid-term survival, and postoperative quality of life.Among 107 patients(More)
OBJECTIVE Opium is an overwhelming public health problem in some countries. Different studies have suggested this drug as a risk factor for cardiovascular disease. Although the effect of opium on immune system, lung disease, nephropathy, stroke, and cardiac arrhythmia has been found in different studies, its effect on postoperation complications is not(More)
Behcet's disease is a multisystem disorder and classified as "vasculitic syndrome with a wide variety of clinical manifestations." Cardiac involvement is very rare but can occur with different presentations including: pericarditis, cardiomyopathy, endocarditis, endomyocardial fibrosis, intracavitary thrombosis, and coronary artery disease. Great vessel(More)
BACKGROUND Based on Acute Kidney Injury Network (AKIN) criteria, we considered acute kidney injury (AKI) as an absolute increase in the serum creatinine (sCr) level of more than or equal to 0.3 mg/dl or 50%. The introduction of Urinary neutrophil gelatinase-associated lipocalin (UNGAL) has conferred earlier diagnosis of AKI. Pentoxifylline (PTX), a(More)
This study was conducted to investigate predictors of mortality before and after isolated coronary artery bypass grafting (CABG). Single-institutional data on risk factors and mortality were collected for 8890 patients who underwent isolated CABG by the same group of surgeons. The relationship between risk factors and outcome was assessed using univariate(More)
BACKGROUND We sought to evaluate the routine echo-Doppler screening of carotid artery stenosis in patients undergoing coronary artery bypass grafting. METHODS A total of 2179 consecutive patients who underwent coronary artery bypass grafting alone or with other cardiac surgery at Tehran Heart Center, Tehran-Iran, between January 2005 and January 2006 were(More)
BACKGROUND Sternal wound infection (SWI) is an uncommon but potentially life-threatening complication of cardiac surgery. Predisposing factors for SWI are multiple with varied frequencies in different studies. The purpose of this study was to assess the incidence, risk factors, and mortality of SWI after coronary artery bypass grafting (CABG) at Tehran(More)
