Acute results and long-term follow-up of percutaneous transluminal coronary angioplasty (PTCA) in 125 patients aged 75 to 90 years (79 men; 46 female; mean age 78 +/- 3 years), with mainly unstable angina (102 patients) are reported. Successful PTCA was achieved in 96 out of 108 patients (89%); occlusions could be reopened in eight out of 17 patients (47%). Thirty-eight procedures were multiple vessel or multiple lesion PTCA, so that the lesion-related success rate of PTCA was higher (91%). Major complications occurred in seven patients (5.6%) including one procedure-related death. In-hospital mortality was 3% and concerned exclusively patients with unstable angina and unsuccessful procedure. At a mean follow-up of 27 +/- 16 months (2 to 82 months) 13 additional patients had died: 10 from cardiovascular causes, three from cancer. In the meantime, three patients underwent non-fatal myocardial infarction and three elective bypass surgery; 26 patients had repeat PTCA. Eighty-seven of the 93 surviving patients with successful primary procedure and reintervention if necessary, were in anginal class I or II; only six were in class III. We conclude that the success rate of PTCA in elderly patients is comparable to that in younger patients, and that a successful procedure leads to continued relief of symptoms.

Among nearly 2,000 consecutive percutaneous transluminal coronary angioplasty (PTCA) patients, 42 patients (36 male, 6 female; mean age 60 ± 11 years) with mainly unstable angina had ejection fractions of < 35% (mean 30 ± 5%). All patients had previous myocardial infarctions; 31 (= 74%) had multivessel disease. Successful procedure was achieved in 35 of the 42 (= 83%) patients, 31 of 35 (= 89%) stenoses could be successfully dilated and 9 of 15 (= 60%) occlusions reopened. In-hospital mortality was 2.4%. Follow-up angiography in 22 of the 35 patients who had been successfully treated showed significant improvement of ejection fraction from 29 ± 5 to 36 ± 7%. At clinical follow-up 19 ± 14 months (2-53 months) after the procedure, nearly all surviving patients were in anginal class I or II, 5 had died from cardiac and 1 from noncardiac causes. Thus, PTCA in patients with severely depressed left ventricular function shows acceptable acute results; attenuation of ventricular dysfunction and continued symptomatic improvement can be achieved. However, late outcome is significantly worse than in patients with normal ventricular function.

Coronary aneurysms resulting from a previous episode of Kawasaki's disease are considered an important cause of myocardial infarction in children. A case of a 19-year-old man presenting with an acute myocardial infarction associated with coronary aneurysms is described. These coronary lesions were previously evaluated angiographically and echocardiographically at the age of 13 years, 5 months after the acute episode of a Kawasaki's disease.
