OBJECTIVE: To determine if the Revised Cardiac Risk Index (Lee) is useful for stratification of patients by risk of both perioperative cardiac morbidity and long-term all-cause mortality in the setting of endovascular repair of abdominal aortic aneurysms. DESIGN: This study was designed as a retrospective review. SETTING: It was conducted at a single academic medical institution. PARTICIPANTS: The analysis included 225 patients with abdominal aortic aneurysms admitted to the authors' institution from 1999 to 2006. INTERVENTIONS: All patients underwent endovascular aortic aneurysm repair. MEASUREMENTS AND MAIN RESULTS: Data were collected from medical records, office charts, and physician quality-assurance databases. There were no in-hospital cardiac deaths. The major adverse cardiac event rate in the perioperative period was 6.2%. Long-term all-cause mortality was 23%. Univariate analysis showed that a history of coronary artery disease (CAD) (likelihood ratio [LR] = 8.7, p = 0.023), history of congestive heart failure (LR = 4, p = 0.042), and a Revised Cardiac Risk Index (RCRI) > or =3 (LR = 8.6, p = 0.004) were significant predictors for perioperative major adverse cardiac events. A history of CAD (LR = 10.7, p = 0.002), echocardiographic evidence of myocardial infarction (LR = 8.5, p = 0.006), exercise tolerance of only 1 block (LR = 8.4, p = 0.005), RCRI > or =3 (LR = 5.6, p = 0.022), and perioperative cardiac events (LR = 15.9, p < 0.0001) were significantly associated with long-term all-cause mortality. Perioperative cardiac events remained highly significant in predicting long-term mortality within the RCRI > or =3 subgroup (LR = 6.1, p = 0.019). CONCLUSIONS: The results of this study confirm that long-term mortality remains high after endovascular repair of abdominal aortic aneurysms. The Lee index may be a useful tool for stratification of high-risk patients from both a short- and long-term perspective in the setting of endoluminal graft repair.
