我们分析了NHLBI PTCA登记中因冠状动脉再狭窄而接受重复PTCA的患者的短期和长期结果。在1880例首次PTCA成功的患者中，203例在发生再狭窄后再次尝试PTCA。重复PTCA通常在第一次手术后6个月内进行。再次PTCA成功率为85.2%。作为重复PTCA的直接结果，1.5%的患者发生心肌梗死，2%的患者需要紧急冠脉搭桥。没有患者因第二次手术而死亡。94%的符合条件的患者可获得1至3年的随访信息。大多数患者（75.9%）没有后续（第三次）PTCA、CABG或心肌梗死，晚期死亡率为0.8%。血管造影随访62例。再扩张病变直径持续增强的比例为66%。因此，重复PTCA手术成功率高，并发症发生率低。大多数患者没有再狭窄，也没有心绞痛。因此，对于再狭窄的患者，应推荐重复PTCA，并将其视为PTCA治疗的一个组成部分。
The short- and long-term outcome of patients within the NHLBI PTCA Registry who underwent repeat PTCA for coronary restenosis were analyzed. Of 1,880 patients in whom an initial PTCA was successful, 203 had a repeat PTCA attempted after restenosis developed. Repeat PTCA was usually performed within 6 months of the first procedure. The success rate of repeat PTCA was 85.2%. As a direct result of repeat PTCA, 1.5% of patients had an MI and 2% required emergency CABG. No patien died as a result of the attempted second procedure. One to 3 years of follow-up information was available in 94% of eligible patients. Most patients (75,9%) did not have a subsequent (third) PTCA, CABG or an MI. The late mortality rate was 0.8%. Angiographic follow-up information was available in 62 patients. Sustained enhancement of the diameter of the redilated lesion was observed in 66%. Thus, repeat PTCA has a high success and a low complication rate. Most patients did not have subsequent restenosis and are free of angina. Hence, repeat PTCA should be recommended for patients who have restenosis and should be considered as an integral component of PTCA therapy.
