Loop A1 F. George Estafanous A1 William C. Sheldon YR 1983 UL http://www.ccjm.org/content/50/1/2.abstract AB The 1981 surgical experience in 2616 consecutive isolated bypass patients is reviewed. Median age of these patients continues to rise, reaching 59 years in 1981 (23% were >65 years and 8% >70 years); 15% were women. Multivessel coronary atherosclerosis occurred in 92% (two-vessel disease in 24% and three-vessel disease in 69%). Left main artery lesions have plateaued at 12% of surgical patients. Abnormal left ventricular contraction was documented in 55%. Operative (hospital) mortality was 0.8%. Major morbidity included perioperative myocardial infarction (principally new Q-waves) in 1.4% and neurologic deficit in 1.7%. Intra-aortic balloon pump usage was 0.9% and 0.8 unit of blood was used per patient; prevalence of internal mammary artery graft usage was 49%; and complete revascularization was achieved in 82%.
