title: [Percutaneous transluminal coronary angioplasty in patients over 75 years old with acute myocardial infarct or unstable angina pectoris].
abstract: Both increasing frequency and technical improvements of percutaneous transluminal coronary angioplasty (PTCA) have focussed attention on possible applications of PTCA in elderly patients with coronary artery disease. From January 1986 to June 1989, among 1872 patients treated with PTCA in our hospital, 42 patients (2.3%) were 75 or more years old. Of these patients, 14 presented with unstable angina, 28 patients suffered from acute myocardial infarction. PTCA was performed on stenoses of left anterior descending artery (43%), circumflex coronary artery (18%), and right coronary artery (39%), respectively. In patients with unstable angina, PTCA in 81% could reduce diameter stenoses of culprit lesions to 50% or less. 43% of patients with acute myocardial infarction had received previous thrombolytic therapy with streptokinase or urokinase applied either systemically or intracoronarily. On cardiac catheterization, 39% of patients presenting with acute myocardial infarction showed total occlusion of the infarct-related vessel. In 75% of patients with acute myocardial infarction, after PTCA, patency of the infarct-related artery (diameter stenoses 50% or less) was observed. In-hospital mortality of patients with acute myocardial infarction subjected to PTCA was 10%, two patients dying in prolonged cardiogenic shock, one in septic shock. In 20% of cases, coronary dissection was observed after PTCA. Non-Q-wave infarction developed in one patient. Three patients had a peripheral vascular complication, and in one patient a transient ischemic attack was observed. No severe catheter-related complications occurred after thrombolytic therapy.(ABSTRACT TRUNCATED AT 250 WORDS)
