Abstract
Over the past decade, the average patient undergoing an open heart procedure has become older and presents with significantly more comorbid risk factors. The most recent data analysis of the Society of Thoracic Surgeons national cardiac surgery database demonstrates that emergency operation, renal insufficiency, left ventricular dysfunction, reoperation, mitral valve insufficiency, advanced age, peripheral vascular disease, and diabetes mellitus are now frequent risk factors in bypass patients.1 The number of women undergoing coronary artery bypass surgery (CABG) continues to increase and they now account for 30% of the patient population. The mean age of patients over the past decade has increased from 58 years in 1980 to a mean of 65 years in 1993. Average left ventricular ejection fraction has steadily worsened over the same time period from 65% to 51%. While operative mortality is 1.8% for elective bypass operations, it climbs to 4.7% for emergent first operations, and to an alarming 12.5% for emergency reoperations. Thus, the safety of cardiopulmonary bypass can no longer be measured by its effectiveness in low-risk young patients requiring a relatively simple operation. One of the continuing challenges for the cardiac surgery team is to develop methods to reduce postoperative morbidity and mortality in high risk patients with multisystem dysfunction.
