BACKGROUND: We analyzed the incidence of late cardiovascular events and mortality after elective infra-/juxtarenal abdominal aortic aneurysm open repair (AAA-OR). METHODS: We included patients who survived AAA-OR in our center in 1988-2006. We registered late cardiac, cerebrovascular, and peripheral vascular events, as well as all-cause and cardiovascular mortality. We calculated patient survival and freedom from cardiovascular events (Kaplan-Meier) and evaluated risk factors (multivariate analysis). RESULTS: We studied 297 patients: 292 (98.3%) men, aged 67 +/- 7 (44-83) years, 143 (48.1%) bifurcated grafts. In a mean follow-up of 78.7 +/- 52.9 months, we registered 203 cardiovascular events in 123 (41.4%) patients, at a rate of 0.16 cardiovascular events/patient-year. Eleven (3.7%) patients suffered graft-related complications. Freedom from cardiovascular events was 94.2%, 67.2%, 45.7%, and 27.6% at 1, 5, 10, and 15 years, respectively. Survival was 96.6%, 74.7%, 50.7%, and 31.5%, respectively. The main cause of death was cardiovascular disease (n = 54, 18.2%), followed by cancer (n = 43, 14.5%). Only four (1.3%) deaths were graft-related. Coronary artery disease and chronic renal failure were predictive of cardiovascular mortality (p = 0.033 and 0.006). CONCLUSION: Although long-term survival is similar to that in the general population, successful AAA-OR patients remain at increased risk of cardiovascular events throughout their lifetime. Graft-related complications are rare, confirming the durability of the procedure. Copyright (c) 2010 Annals of Vascular Surgery Inc. Published by Elsevier Inc. All rights reserved.
