Patients undergoing emergency coronary artery bypass grafting represent a unique and high-risk population that remains challenging for cardiac surgeons. We examined the changing trends in patients undergoing emergency bypass grafting over the past 20 years.
We conducted a retrospective review of our database between 1990 and 2009 and patients were divided into 2 groups based on year of operation: 1990-1999, n = 393; 2000-2009, n = 184. The primary outcomes of interest for this study are operative mortality and incidence of low cardiac output syndrome.
The percentage of patients undergoing emergency coronary bypass grafting has decreased from 2.7% to 1.7% over time. The percentage of patients with dyslipidemia, hypertension, triple vessel disease, peripheral vascular disease, and left main disease increased over time (P
