Background: Endovascular abdominal aortic aneurysm (AAA) repair (EVAR) is associated with a decreased incidence of perioperative cardiac complications compared with open repair. However, EVAR is not associated with long-term survival benefit. This study assessed the effect of perioperative asymptomatic cardiac damage after EVAR on long-term prognosis. Methods: In 220 patients undergoing elective EVAR, routine sampling for levels of cardiac troponin T and electrocardiography (ECG) were performed on days 1, 3, and 7 during the patient's hospital stay. Elevated cardiac troponin T was defined as serum concentrations >= 0.01 ng/mL. Asymptomatic cardiac damage was defined as cardiac troponin T release without symptoms or ECG changes. The median follow-up was 2.9 years. Survival status was obtained by contacting the Office of Civil Registry. Results: Release of cardiac troponin T (median, 0.08 ng/mL) occurred in 24 of 220 patients, of whom 20 (83%) were asymptomatic and without ECG changes. Patients with asymptomatic cardiac damage had a mortality rate of 85% after 2.9 years vs 51% for patients without perioperative cardiac damage (P < .001). Also after adjustment for clinical risk factors and medication use applying multivariate Cox regression analysis, asymptomatic cardiac damage was associated with a 2.3-fold increased risk for death (95% confidence interval, 1.1-5.1). Statin use was associated with a reduced long-term risk for death (hazard ratio, 0.5; 95% confidence interval, 0.3-0.9). Conclusion: Asymptomatic cardiac damage in patients undergoing EVAR is associated with poor long-term outcome. Routine perioperative cardiac screening after EVAR might be warranted.
