以往报道仅少数老年患者行单支成形术,本文叙述老年患者行多支成形术的近期及长期效果。方法研究对象包括所有作双支或三支成形术的老年(≥65岁)患者,除外因急性心梗而作紧急PTCA者。原狭窄(内径减少)≥70％。术后狭窄≤40％,被认为扩张成功。结果 1981年1月至1990年7月间1373例老年患者择期进行1640次多支成形术。其中224例(13.6％)左室功能差(EF≤40％),412例(25.1％)曾作CABG,48例(2.9％)行左主干成形术。1640次PTCA中1236次扩张双支,404次扩张三支。在5987处狭窄中5724处(96％)扩张成功。平均每次PTCA
Previously reported only a small number of elderly patients undergoing uniplasty, this article describes the elderly patients with multi-branch plasty in the short and long-term results. METHODS Subjects included all elderly patients (≥65 years) with double-branch or triple-vessel surgery, except for those with acute PTCA who had acute myocardial infarction. The original stenosis (diameter reduction) ≥ 70%. Postoperative stenosis ≤ 40%, is considered successful expansion. Results From January 1981 to July 1990, 1373 elderly patients underwent 1640 multi-limbal elective angioplasty. Of these, 224 (13.6%) had poor left ventricular function (EF ≤ 40%), 412 (25.1%) had CABG and 48 (2.9%) had left main stemming. 1,240 times in 1640 PTCA double dilatation, 404 times the expansion of three. At 5787, stenosis at 5987 (96%) dilated successfully. Average per PTCA
