Abstract

This study assesses risk factors in elderly vascular surgery patients and to evaluate whether perioperative cardiac medication can reduce postoperative mortality rate. In a cohort study, 1693 consecutive patients > or =65 years undergoing major non-cardiac vascular surgery were preoperatively screened for cardiac risk factors and medication. During follow-up (median: 8.2 years), mortality was noted. Hospital mortality occurred in 8.1% and long-term mortality in 28.5%. In multivariate analysis, age, coronary artery disease, heart failure, cerebrovascular disease, renal failure and diabetes were significantly associated with increased hospital and long-term mortality. Perioperative aspirin (OR: 0.53, 95% confidence interval: 0.34-0.83), beta-blockers (OR: 0.32, 95% CI: 0.19-0.54) and statins (OR: 0.35, 95% CI: 0.18-0.68) were significantly associated with reduced hospital mortality. In addition, aspirin (HR: 0.65, 95% CI: 0.53-0.81), angiotensin-converting enzyme (ACE)-inhibitors (HR: 0.74, 95% CI: 0.59-0.92), beta-blockers (HR: 0.61, 95% CI: 0.48-0.76) and statins (HR: 0.65, 95% CI: 0.49-0.87) were significantly associated with reduced long-term mortality. Heterogeneity tests revealed a gradient decrease of mortality risk in patients from low to high age using statins (p=0.03). In conclusion, age is an independent predictor of hospital and long-term mortality in elderly patients undergoing major vascular surgery. Aspirin, ACE-inhibitors, beta-blockers and statins reduce long-term mortality risk. Especially the very elderly may benefit from statin therapy.
