Abdominal aortic aneurysms and coronary artery disease: is a more aggressive approach indicated?
A retrospective study was undertaken to assess the influence of known ischaemic heart disease on the operative and the long-term survival of patients undergoing elective repair of an abdominal aortic aneurysm. One hundred and seventy-one patients underwent elective surgery between June 1977 and December 1983. The patients were divided on routine clinical grounds into cardiac and noncardiac groups. Ninety-five patients had a history of heart disease and/or an abnormal resting pre-operative ECG. Seventy-six patients had no history of heart disease and a normal pre-operative resting ECG. Two of the seven operative deaths were due to myocardial infarction with one each from the cardiac and noncardiac groups. Eight patients suffered an acute myocardial infarction with five from the cardiac and three from the noncardiac group and this was not significantly different. The overall survival of 95% at 1 year and 76% at 5 years closely follows the age/sex matched Australian population. The survival at 1 year in the cardiac group was 97% and 95% in the noncardiac group. The 5 year survival was 72% and 79% respectively. During follow-up to December 1984, 11 patients died from ischaemic heart disease with six from the cardiac and five from the noncardiac group. No significant difference was found between the two groups in the incidence of myocardial infarction or the short- and long-term survival. This study does not support a more aggressive approach to coronary artery disease in the pre-operative management of patients with abdominal aortic aneurysm.
