Abstract
From the Department of Vascular Surgery, The Cleveland Clinic Foundation, Cleveland, Ohio Routine coronary angiography has been recommended to all patients undergoing carotid endarterectomy at the Cleveland Clinic since 1978. Patients found to have severe, correctable coronary artery disease (CAD) have been advised to undergo myocardial revascularization as a staged or combined procedure in conjunction with carotid endarterectomy in an attempt to reduce the incidence of fatal myocardial infarction during the postoperative period, and during the late follow-up interval. In order to provide an historic standard with which the results of this approach may eventually be compared, complete follow-up information has been obtained for 95% of 335 consecutive patients who underwent carotid endarterectomy between 1969 and 1973. Fatal myocardial infarction accounted for 60% of early deaths within 30 days of operation and occurred in 1.8% of the entire series. Among the patients who survived operation, the five-year mortality rate was 27%, and the 11-year mortality rate was 48%. Myocardial infarction caused 37% of the deaths that occurred within five years after operation and 38% of the deaths that have occurred within 11 years. Differences in the incidence of fatal myocardial infarction within five years after operation between a group of 116 patients who had no clinical evidence of CAD and a group of 209 patients suspected to have CAD attained statistical significance (p ≤ 0.1) despite the fact that 67 patients suspected to have CAD eventually underwent myocardial revascularization. Improvement in actuarial survival (p ≤ 0.05) and reduction in the late mortality rate (p ≤ 0.01) were statistically significant for the subset of patients with suspected CAD who had aortocoronary bypass graft proceduresThis publication has 17 references indexed in Scilit:
