Background: Studies have shown an inverse relationship between socioeconomic status (SES) and mortality due to coronary heart disease (CHD). Little is known about this association in Iran. This study aimed to investigate whether mortality after myocardial infarction (MI) varies by SES. Methods: In a retrospective study, 1283 MI patients who hospitalized in(More)
BACKGROUND Postoperative arrhythmias are among the most common complications of cardiac surgery. Total serum magnesium concentration will change after coronary bypass surgery but compensatory prophylactic administration of magnesium has remained a controversial issue. We studied whether prophylactic administration of magnesium could prevent post-coronary(More)
OBJECTIVE The objective of this study was to ascertain the reliability and predictive power of the World Health Organization's Quality of Life Questionnaire (WHOQOL-BREF) and Short Form 36 Health Survey questionnaire (SF-36) in coronary artery disease patients. METHODS Between May and September 2006, patients with coronary artery disease hospitalized in(More)
BACKGROUND The effect of opium on glycemic control in diabetics is a controversial issue, as some studies have shown glucose lowering effect of opium in diabetes while the results of other studies do not support this idea. The possible role of opioid peptides in the regulation of food intake has been previously investigated. However, there is no data(More)
Serum creatinine is still the most important determinant in the assessment of perioperative renal function and in the prediction of adverse outcome in cardiac surgery. Many biomarkers have been studied to date; still, there is no surrogate for serum creatinine measurement in clinical practice because it is feasible and inexpensive. High levels of serum(More)
OBJECTIVE Evaluating renal function by calculating creatinine clearance as an alternative measure to serum creatinine may give a better estimation of postoperative renal function in patients undergoing coronary artery bypass grafting. METHODS Using our database, we conducted a retrospective review of the records of all 11,884 patients aged 21 years or(More)
BACKGROUND We presumed that the surgeon himself has an impact on the results after coronary artery bypass grafting (CABG) as there is no unique protocol for the discharge of post-operative cardiac patients at our institution. Therefore, we examined whether the surgeon himself has an impact on the intensive care unit (ICU) stay of isolated CABG patients. (More)
Although red blood cells (RBCs) transfusion is sometimes associated with adverse reactions, anemia could also lead to increased morbidity and mortality in high-risk patients. For these reasons, the definition of perioperative strategies that aims to detect and treat preoperative anemia, prevent excessive blood loss, and define "optimal" transfusion(More)
BACKGROUND The World Health Organization Quality of Life Questionnaire (WHOQOL)-BREF is one of the most known general questionnaires for assessment of quality of life (QOL) in both healthy populations and in various diseases subgroups. The aim of the present study was to examine the construct validity of this questionnaire in patients with coronary artery(More)
BACKGROUND Opium is a unique substance, regarding its analgesic effects. This may change the deteriorating effects of coronary artery disease (CAD) on quality of life (QOL) in addicted patients. OBJECTIVES We studied the QOL in opium-addicted and non-addicted CAD patients so as to determine the relationship between CAD risk factors and the subscales of(More)
