Angioplasty (PTCA) was successfully performed in 404 (94%) of 428 patients. Two lesions were attempted in 74%, 3 in 21% and 4 or more in 6% of cases. Significant complications included: 11 (2.5%) transmural infarctions, 9 (2.1%) emergency surgeries, and 6 (1.4%) mortalities. A lesion recurrence occurred in 106 (26%) of 404 patients with 81 (91%) of 89 patients having a successful 2nd PTCA. A 2nd recurrence occurred in 15 (19%) of 81 patients with 13 of 15 patients having a successful 3rd PTCA. Followup (mean: 28.3 months) showed an improved anginal status in 83% of patients. The probability of survival at 51 months was 93%. Multiple lesion PTCA in carefully selected patients has a good success rate and an acceptable complication rate.
428例患者中有404例（94%）成功进行了血管成形术（PTCA）。74%的病例尝试治疗2处病变，21%尝试治疗3处病变，6%尝试治疗4处或更多处病变。严重并发症包括：11例（2.5%）透壁性心肌梗死、9例（2.1%）急诊手术和6例（1.4%）死亡。404例患者中有106例（26%）出现病变复发，89例患者中有81例（91%）成功进行了第二次PTCA。81例患者中有15例（19%）出现第二次复发，15例患者中有13例成功进行了第三次PTCA。随访（平均28.3个月）显示83%的患者心绞痛症状改善。51个月时的生存率为93%。在精心挑选的患者中进行多处病变PTCA有良好的成功率和可接受的并发症发生率。
