The early results of endovascular treatment of chronic coronary occlusion were studied. Immediate success rates were 67%. The factors that promote successful endovascular treatment in patients with this condition were as follows: less than 2-month disease duration, well-developed intersystemic collaterals, no "bridge" collaterals. Successful recanalization for chronic coronary occlusion improves the quality of life and bicycle ergometer test finding in patients, which reduces their needs of nitrates and beta-blockers. Coronary occlusion stenting yields better immediate angiographic results than does balloon angioplasty: residual stenosis and the minimum diameter of stenosis after stenting were 13.61 +/- 6.3% and 2.69 +/- 0.4 mm, respectively; those after balloon angioplasty were 23.1 +/- 8.1% and 2.31 +/- 0.37 mm, respectively.
对慢性冠状动脉闭塞的血管内治疗早期结果进行了研究。即刻成功率为67%。促进这种情况下患者血管内治疗成功的因素如下：病程少于2个月、系统间侧支循环良好、无“桥接”侧支循环。慢性冠状动脉闭塞的成功再通可改善患者的生活质量和自行车测力计测试结果，从而减少他们对硝酸盐和β受体阻滞剂的需求。冠状动脉闭塞支架置入术比球囊血管成形术产生更好的即刻血管造影结果：支架置入术后的残余狭窄和狭窄最小直径分别为13.61±6.3%和2.69±0.4mm；球囊血管成形术后分别为23.1±8.1%和2.31±0.37mm。
