ABSTRACT
BACKGROUND AND

OBJECTIVES:

The elderly is the fast growing segment of the population in Korea. Elderly patients undergoing coronary revascularization are considered a high-risk group. Few data exist that relate the results of stenting in treating coronary artery disease in the elderly population. This study sought to compare the short- and long-term outcomes of elderly patients undergoing coronary artery stenting with those of younger patients.

METHODS:

All elderly patients 70 years of age who underwent coronary artery stenting between January 1997 and July 1999 (n = 106) at our centers were compared to the patients <70 who underwent coronary artery stenting during the same time period (n = 597).

METHODS:

Elderly patients presented with lower ejection fraction (52.9% vs. 57.4%, p = 0.001), more unstable angina (47% vs. 31%, p = 0.003), and more multivessel disease (67% vs. 51%, p = 0.005) than younger patients. Major in-hospital complications including death (0.9% vs. 0.5%, p = NS), procedural acute Q-wave myocardial infarction (0.9% vs. 0.3%, p = NS), and emergency CABG (0% vs. 0.3%, p = NS) did not differ between two groups. And also vascular complication rate was similar between two groups(1.9% vs. 1.0%, p = NS). Angiographic follow-up, obtained in both groups, demonstrated similar restenosis rates (26.5% vs. 24.9%, p = NS). Long-term clinical follow-up at 12 months showed major adverse cardiac events including death, acute myocardial infarction, and repeat revascularization were significantly higher in elderly patients than in younger patients (18.3% vs. 12.6%, p = 0.04).

CONCLUSIONS:

Elderly patients with higher risk factors who underwent coronary artery stenting had similar rates of in-hospital procedural complications and similar rates of 6 months angiographic restenosis, compared to younger patients. Overall rates of major adverse cardiac events in the elderly population at 12 months postcoronary artery stenting were significantly higher than those of younger patients.
