Initial and short-term results of percutaneous transluminal coronary angioplasty in patients over 70 years old: recent improvements in effectiveness].

Elderly patients have a higher incidence of procedure-related complications and recurrent angina after percutaneous transluminal coronary angioplasty (PTCA). However, early success rates seem to have improved. To determine whether outcome of PTCA in the elderly has changed recently, we compared initial results and short-term outcome in patients over 70 years old in two groups; 64 patients with 70 PTCA lesions who underwent first elective PTCA in 1982-1989 (early group) and 140 patients with 153 PTCA lesions in 1990-1993 (late group). The mean age of the late group was significantly older than that of the early group (74 +/- 3 vs 73 +/- 2 years, p < 0.01). The two groups had similar clinical characteristics including sex, prior myocardial infarction and multivessel disease. The overall success rate of PTCA was significantly higher in the late group than in the early group (92.8% vs 82.8%, p < 0.05). The rate of abrupt closure was similar in the two groups (2.9% vs 2.6%). Major complications (procedural myocardial infarction, emergency bypass surgery, hospital death) occurred in 4.7% of the early group and in 3.6% of the late group. Angiographic restenosis occurred in 41.5% of the early group and in 33.6% of the late group. Cardiac events (cardiac death and/or myocardial infarction) occurred in 6.6% of the early group and in 1.5% of the late group (p = 0.06). The initial success rate of PTCA has improved in the elderly as well as younger patients (< 70; 92.8% vs 91.6%). We conclude that PTCA can be performed with high initial success and satisfactory short-term outcome in patients over 70 years old.
