title: [Percutaneous transluminal coronary angioplasty for postinfarction residual ischemia: mid- and long-term results].
abstract: Aim of this study was to assess the long-term results of PTCA in patients with a recent myocardial infarction. The study population consisted of 244 consecutive patients who underwent a PTCA < or = 30 days after myocardial infarction either because of angina (116 patients), or because of provoked ischemia (62 patients), or in the absence of both (66 patients). "Simple" balloon angioplasty, without adjunctive devices, was performed. Most of the patients were seen at 1 year intervals at the outpatient clinic; otherwise information was gathered either from the family physician or by telephone. The following events were noted during a follow-up of 6-102 months (median 39 months): death, myocardial infarction, need for re-PTCA or surgical revascularization, recurrence of angina. Survival and event-free curves were calculated according to the method of Kaplan and Meier; statistical comparisons between the curves were obtained by the log-rank test. Periprocedural deaths, infarctions and surgical revascularizations are included in the actuarial curves. Differences were examined between patients with Q and non-Q wave infarctions, single vessel versus multivessel disease, left ventricular ejection fraction > or 50% versus < 50%. A clinical success was achieved in 85% of the procedures. Sixteen patients were lost at follow-up. Overall, within the first 30 days and during follow-up, 12 (4.9%) patients died, 19 (7.7%) suffered from myocardial infarction, 34 (13.9%) required re-PTCA or surgical revascularization, and 63 (25.8%) experienced angina again.(ABSTRACT TRUNCATED AT 250 WORDS)
