Percutaneous transluminal coronary angioplasty (PTCA) was successful in 91% of 76 patients with unstable angina pectoris refractory to pharmacological treatment. However, the rate of acute occlusion and reocclusion was rather high (95). Restenosis developed in 56.5% of successful cases after initial PTCA, and 29 patients underwent 2nd, and nine 3rd PTCA. Most refractory unstable angina can be controlled by PTCA, which may require repeating in some patients.
经皮腔内冠状动脉成形术（PTCA）在76例药物治疗无效的不稳定型心绞痛患者中成功率为91%。然而，急性闭塞和再闭塞率相当高（95）。初次PTCA成功的病例中56.5%出现再狭窄，29例患者接受了第二次PTCA，9例接受了第三次PTCA。大多数难治性不稳定型心绞痛可通过PTCA得到控制，部分患者可能需要重复进行。
