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 patient 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.
对美国国立心肺血液研究所经皮冠状动脉腔内血管成形术（PTCA）登记处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进行了分析。在1880例首次PTCA成功的患者中，203例在出现再狭窄后尝试进行重复PTCA。重复PTCA通常在首次手术后6个月内进行。重复PTCA的成功率为85.2%。重复PTCA的直接结果是，1.5%的患者发生心肌梗死（MI），2%的患者需要紧急冠状动脉旁路移植术（CABG）。没有患者因第二次尝试手术而死亡。94%的符合条件的患者有1至3年的随访信息。大多数患者（75.9%）没有进行后续（第三次）PTCA、CABG或发生MI。晚期死亡率为0.8%。62例患者有血管造影随访信息。66%的患者观察到再次扩张病变的直径持续增大。因此，重复PTCA成功率高且并发症发生率低。大多数患者没有后续再狭窄且无心绞痛。因此，对于发生再狭窄的患者应推荐重复PTCA，并且应将其视为PTCA治疗的一个组成部分。
