Short and long-term outcomes of patients with coronary artery bypass surgery

BACKGROUND: Coronary artery disease (CAD) is a major problem in Iran as well as throughout the globe, and coronary artery bypass grafting (CABG) surgery is an appropriate option for many patients with symptomatic and severe CAD. The main purpose of this study was assessment of the short and long-term outcomes of patients undergoing CABG in Yazd Province, Iran.METHODS: This historical cohort study examined the mortality rates of patients who had undergone CABG in Afshar Hospital in Yazd from ۲۰۱۱ to ۲۰۱۳. During this period, ۲۵۱۰ patients undergoing CABG were entered into the study and then followed for in-hospital and long-term mortality.RESULTS: Mean age of the patients was ۶۱.۳۷ ± ۱۰.۵۰ years and ۳۴.۱% were women. In-hospital mortality turned out to be ۳.۷% and age over ۷۰, left ventricular (LV) dysfunction, female gender, and left main (LM) involvement induced significant higher in-hospital mortality. Of all the patients, ۸۴.۱% were followed for a period of ۴۱ ± ۲۰ months. The survival rate proved to be ۹۲.۴% in one year and ۸۲.۹% in five years. The patients with age over ۷۰, diabetes mellitus (DM), and LV systolic dysfunction (LVSD) showed significant lower survival rate, whereas the patients with utilization of left internal mammary artery (LIMA) demonstrated significant higher survival rate.CONCLUSION: In-hospital and long-term mortality rate of patients undergoing CABG surgery is acceptable in comparison with other studies and more effort is needed into making this event a success.
