These \u2265 70 years patients were analyzed regarding the operative morbidity, the 30\u2010day operative mortality, and the operative mortality's relation to coronary artery disease and ventricular wall motion abnormalities. The operative mortality was not different for the 174 patients operated upon before and the 500 patients after 1980. A mean of 3.4 grafts were placed during surgery. The complications encountered included a 7.1 % perioperative infarction rate, a 4.2% incidence of cerebrovascular accident, a 3.6% incidence of reoperation for bleeding, a 2.4% incidence of renal failure, and a 2.1 % incidence of pulmonary embolism. The overall operative mortality was 7.4%. The extent of coronary artery disease was distributed among patients such that 8.4% had single\u2010, 28.0% had double\u2010, and 63.6% had triple\u2010vessel disease. The operative mortality as related to the extent of coronary artery disease was 5.2% for single\u2010, 8.9% for double\u2010, and 7.0% for triple\u2010vessel disease. The operative mortality was 6.7% with no and 7.9% with left ventricular wall motion abnormalities. The operative mortality was 1.9% with 1 segmental wall motion abnormality, and increased to 13.3% (p&lt;0.05) with 4\u20136 segmental wall motion abnormalities. The operative mortality for single\u2010vessel disease was 5.4% with normal and 4.3% with abnormal wall motion; for double\u2010vessel disease it was 4.3% with normal and 13.2% with abnormal wall motion, (p&lt;0.05); and, for triple\u2010vessel disease, 8.3% with normal and 6.0% with abnormal wall motion. Actuarial life\u2010table analysis indicated that the probability of surviving at least 7 years is 64.6\u22653.6%. There was no difference in the survival at 4 years regardless of the extent of coronary disease. After 4 years, the difference in survival between single\u2010 and triple\u2010vessel disease became significant (single, 91 % versus triple, 78%; p&lt;0.05). The probability of survival at 7 years was affected by the presence of wall motion abnormalities (normal, 73% versus abnormal, 56%, p&lt;0.05). These data suggest that coronary bypass surgery when performed in patients \u2265 70 years has a significant operative mortality which is probably not related to the extent of coronary artery disease, but to the severity of left ventricular wall motion abnormalities. Surviving patients have a relatively good long\u2010term outlook which, nevertheless, is adversely affected by the extent of coronary disease, and the severity of left ventricular wall motion abnormalities.<\/jats:p>","DOI":"10.1002\/clc.4960100703","type":"journal-article","created":{"date-parts":[[2009,2,7]],"date-time":"2009-02-07T03:41:44Z","timestamp":1233978104000},"page":"377-382","source":"Crossref","is-referenced-by-count":19,"title":["Coronary artery bypass surgery in patients over age 70 years: Report from the milwaukee cardiovascular data registry"],"prefix":"10.1002","volume":"10","author":[{"given":"G.","family":"Dorros","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Daley","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Assa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
