To assess the incidence and clinical presentation of restenosis after successful coronary angioplasty, and the short- and mid-term results of its treatment, 160 patients, who underwent a first coronary angioplasty between May 1987 and December 1988, were closely monitored. Restenosis is defined as a loss of 50% or more of the initial gain in area and/or 30% or more in diameter, or chronic coronary occlusion. These criteria were met in 43 patients (27%) within 5.1 months (1-6 months), on the average, after angioplasty. Restenosis was expressed as unstable angina in 51% of the patients, stable angina in 30%, and abnormal thallium myocardial scintigraphy under exercise in 14%. Myocardial infarction was never the revealing symptom. In 63% of the cases, the pain caused by restenosis repeated the initial angina. A second angioplasty was performed in 75% of the patients with a success rate of 93%, in the absence of an occlusion, and a 37% rate of further restenosis.
为评估成功进行冠状动脉血管成形术后再狭窄的发生率和临床表现，以及其治疗的短期和中期结果，对1987年5月至1988年12月期间首次接受冠状动脉血管成形术的160例患者进行了密切监测。再狭窄定义为初始面积增加丧失50%或更多和/或直径减少30%或更多，或慢性冠状动脉闭塞。血管成形术后平均5.1个月（1至6个月）内，43例患者（27%）符合这些标准。51%的患者再狭窄表现为不稳定型心绞痛，30%为稳定型心绞痛，14%为运动时铊心肌闪烁显像异常。心肌梗死从未作为首发症状出现。63%的病例中，再狭窄引起的疼痛与初始心绞痛相似。75%的患者接受了第二次血管成形术，在无闭塞的情况下成功率为93%，再次发生再狭窄的比例为37%。
