老年冠心病患者经皮冠状动脉腔内血管成形术的临床评价

目的评价老年冠心病患者经皮冠状动脉（冠脉）腔内血管成形术（ＰＴＣＡ）的临床疗效。方法将２３６例老年（共２９７支冠脉血管）和３６０例非老年（共４５１支冠脉血管）冠心病患者接受ＰＴＣＡ的结果作对比分析。结果老年患者的冠脉病变特点和发病血管支数与非老年患者差异无显著性；老年组血管扩张病例成功率为９５．４％，随着近年冠脉内支架置入率的增加，主要的ＰＴＣＡ并发症较前降低；以上结果与非老年组比较差异均无显著性。结论对于老年冠心病患者，ＰＴＣＡ是一种有效而安全的冠脉血运重建方法。

Percutaneous transluminal coronary angioplasty in senile patients with coronary heart disease

Objective To evaluate the outcome of percutaneous transluminal coronary angioplasty (PTCA) in senile patients with coronary heart disease. Methods The results of PTCA in 236 cases (297 vessels) of senile patients who received the procedure from 1994 to 1997 were analysed and compared with those in 360 cases (451 vessels) of a non senile group. Results There were not much angiographic difference between the senile and non senile group. The clinical success rate of PTCA in senile group was 95 4% which was comparable with a rate of 94 7% in the non senile patients. With the increase of cases of stent implantation in recent years, the overall frequency of major complications were less than before in both groups and procedure failure rate was decreased year by year.The results did not differ significantly from those obtained in non senile group. Conclusions It is effective and safe for senile patients to receive PTCA procedure.
