连续84例80～89岁的症状性冠心病病人进行冠脉造影,测定冠脉病变的范围和程度,探讨 CABG 和 PTCA 的可行性。单支、双支、叁支和左主干明显狭窄者分别有12例(14%)、18例(22%)、48例(57%)和11例(13%)。根据冠脉造影所见,78例明显冠脉狭窄者中,69例(88%)适宜作 CABG,仅21例(31%)适宜作 PTCA。19例施行 CABG,手术死亡率为16%,重大并发症率为37%。
A total of 84 patients with symptomatic coronary heart disease (80-89 years old) underwent coronary angiography to determine the extent and degree of coronary artery lesion, and to explore the feasibility of CABG and PTCA. Twelve patients (14%), 18 patients (22%), 48 patients (57%) and 11 patients (13%) were single, double, triple and left main stenosis respectively. According to coronary angiography, 69 (88%) of the 78 patients with significant coronary stenosis were suitable for CABG, and only 21 (31%) were suitable for PTCA. Nineteen patients underwent CABG, with an operative mortality rate of 16% and a significant complication rate of 37%.
