Late results of coronary angioplasty in patients with left ventricular ejection fractions ≤ 40%

摘要: Abstract Left ventricular (LV) function is the most important independent predictor of long-term survival in patients with coronary artery disease, and results bypass surgery improving setting depressed LV are well documented. Data regarding outcome undergoing angioplasty limited. From 1983 through 1989, 343 consecutive an ejection fraction (EF) ≤ 40% (mean 34% ± 5%) elective were evaluated, retrospectively. The mean age was 61 10 years 80% men. Angiographic success (469 496 narrowings) 95%. Major complications occurred 26 (7.6%): emergency (n = 11), nonfatal myocardial infarction 8), death 9). Follow-up available for 99% clinical 36 22 months). Fourteen (4.5%) developed 72 (23%) had symptomatic restenosis, 32 requiring repeat or atherectomy 29 surgery. Fifty-six (18.2%) died. Three-year 84%. EF a significant death: 3-year 69%, 83% 92%, respectively, 30%, 31% to 35%, 36% (p 0.0001). A high angiographic rate acceptable procedural risk encountered angioplasty. mortality rate, however, substantial directly related degree dysfunction.
