老年冠心病患者经皮冠状动脉腔内成形术结果评价

An evaluation of the results of percutaneous transluminal coronary angioplasty in aged patients with coronary heart disease

目的评价一组老年冠心病患者行经皮冠状动脉腔内成形术（ＰＴＣＡ）的疗效。方法将６５例老年（８９支血管）和１１７例老年前期（１４９支血管）冠心病患者的ＰＴＣＡ结果作对比研究。结果老年组血管扩张成功率９４．４％，临床成功率９２．３％，主要并发症发生率为６．１％，再狭窄发生率为３２．５％。以上结果与老年前期组比较差异均无显著性。术后症状改善率两组相同，都在９０．０％以上。仅老年组再次ＰＴＣＡ频率明显高于老年前期组（ｘ２检验，Ｐ值＜０．０５）。结论对于老年冠心病患者，ＰＴＣＡ是一种有效及安全的冠脉血管重建措施。

Objective The outcome of percutaneous transluminal coronary angioplasty(PTCA) in aged patients with coronary heart disease is controversial;in this study the effects of PTCA in a group of elderly patients were evaluated. Methods Analyzing and comparing the results of PTCA in 65 senile(89 vessels) with those in 117 presenile patients(149 vessels).Results The angiographic and clinical success rates for senile group were 94.4% and 92.3%,respectively,the overall frequency of major complications was 6.1%,and the incidence of restenosis was 32.5% in the elderly group.The results did not differ significantly from those obtained in presenile group.The proportion with symptomatic improvement after the procedure was similar in the senile and presenile,being over 90% in both.However the elderly patients had a significantly higher frequency of repeat PTCA (P<0.05).Conclusion PTCA is an effective and safe measure of coronary revascularization in elderly patients.
