742-3 In Hospital and Long Outcome After a Third Coronary Bypass Procedure

Increasingly patients are returning for third and even fourth coronary artery bypass grafting (CABG) procedures. The in hospital and long term outcome of patients undergoing a third CABG were reviewed. The time from the first to second CABG was 5.2±3.6 years and from the second to the third CABG 6.7±4.2 years. There were 107 patients, age 60±9 years, 91% were male. 33% had hypertension, 17% diabetes, 86% class III or IV angina and 6.4% congestive failure. 72% had 3 vessel disease. The in-hospital mortality was 9.3%, with 1.9% strokes, and 8.4% myocardial infarction. The 5 and 10 year survival were 0.79 and 0.57. The 5 and 10 year myocardial infarction free survival were 0.59 and 0.26. Patients undergoing a third CABG suffer from severe disease. Most were severely symptomatic, the majority had suffered a myocardial infarction and had 3 vessel disease.While operative mortality in patients undergoing a third coronary bypass procedure was reasonable at 9.3%. continuing events over time limit long term prognosis
