Angioplasty versus coronary artery bypass in octogenarians

Area of Science:

• Cardiology
• Geriatric Medicine
• Interventional Cardiology

Background:

• Significant coronary artery disease presents unique challenges in octogenarian patients.
• Treatment strategies must balance efficacy with the increased risks associated with advanced age.

Purpose of the Study:

• To compare the early and late outcomes of percutaneous transluminal coronary angioplasty (PTCA) versus coronary artery bypass grafting (CABG) in octogenarians.
• To identify predictors of mortality in this high-risk population.

Main Methods:

• Retrospective analysis of 310 octogenarian patients with significant coronary artery disease.
• Comparison of patient characteristics, procedural outcomes, hospital mortality, length of stay, and long-term survival between PTCA and CABG groups.
• Multivariate analysis to determine independent predictors of hospital mortality.

Main Results:

• CABG patients had more severe disease (three-vessel disease, lower ejection fraction) than PTCA patients.
• Hospital mortality was 8.57% for PTCA and 5.8% for CABG.
• Five-year actuarial survival was 55% for PTCA and 66% for CABG (p < 0.01).
• Three-year cardiac event-free survival was 61% for PTCA and 81% for CABG (p < 0.01).

Conclusions:

• Coronary artery bypass grafting (CABG) offers superior long-term survival and better event-free survival compared to percutaneous transluminal coronary angioplasty (PTCA) in octogenarians with significant coronary artery disease.
• Despite differences in patient selection, CABG appears to be a more effective revascularization strategy for this elderly population.
• Failed PTCA, acute myocardial infarction, and emergency CABG were significant predictors of hospital mortality.
