Percutaneous transluminal coronary angioplasty in patients aged 70 years and older: immediate and long-term results.
We analyzed all coronary angioplasty procedures performed in patients aged greater than 70 yr since 1987. There were a total of 92 patients with a mean age of 74 +/- 4 yr (range 70-82). The clinical diagnosis was unstable angina in 79%. Single-vessel disease was present in 41%, double-vessel in 29% and triple-vessel in 30% of patients. A left ventricular ejection fraction of less than 40% was present in 18 patients. Angioplasty was attempted on one vessel in 52 patients (56%), on two vessels in 29 patients (32%) and in three vessels in 10 patients (11%). Angiographic success was achieved in 96% of stenoses and in 53% of chronic total occlusions attempted. Complete revascularization was achieved in 56% of patients. Complications included three patients (3.2%) who underwent emergency coronary artery bypass grafting, 1 patient (1.1%) who sustained a myocardial infarction and 5 patients (5.4%) who died. During hospitalization, which averaged 3 +/- 2 days, 1 patients sustained reversible renal failure and 5 patients required blood transfusion for a large groin hematoma. Clinical success at discharge was 83%. At a mean follow-up of 13 months (range 3-45 months), symptomatic improvement was observed in 59 of the 76 patients who had achieved clinical success, with 42 of these patients (55%) being asymptomatic. The following clinical events occurred: myocardial infarction in 1 patient, new percutaneous transluminal coronary angioplasty in 9 and 3 patients died of cardiac reasons.(ABSTRACT TRUNCATED AT 250 WORDS)
