Clinical factors associated with long-term mortality following vascular surgery: Outcomes from The Coronary Artery Revascularization Prophylaxis (CARP) Trial

Kaplan-Meier survival curves are shown following vascular surgery for those patients excluded from the main trial because of absence of multiple cardiac risks as the only exclusion factor (N = 2314), the remaining patients who were excluded for other reasons (N = 2100) and the randomized cohort (red; N = 462). The 2.5-year survival following vascular surgery in the excluded patients with minimal cardiac risks was 0.88 compared with 0.75 in all of the remaining excluded patients and 0.80 in the randomized patients (P < .0001). Preoperative cardiac risk variables included a history of angina, prior myocardial infarction, previous diagnosis of congestive heart failure, ventricular arrhythmias that have required treatment, pathological q-waves on a baseline EKG and diabetes.

The clinical variables that were associated with an increased risk of mortality at a median of 2.5 years following vascular surgery, as determined by the Cox regression analysis, are shown for those patients presenting with an expanding abdominal aortic aneurysm along with the hazard ratios and 95% confidence intervals.
