１４例不稳定性心绞痛患者，男性１２例，女性２例，平均年龄５５岁，均因药物治疗无效而进行ＰＴＣＡ治疗。总计１６个血管段、前降支９段，回旋支４段，右冠状动脉３段。术后执行以步行为主要内容的一周康复训练程序，全部病例均顺利完成，表明以步行为主的非监护康复训练对不稳定性心绞痛ＰＴＣＡ术后患者是安全可行的。 Among 14 patients with unstable angina, 12 were male and 2 were female, with an average age of 55 years. All were treated with PTCA due to ineffective drug treatment. A total of 16 vascular segments, 9 segments of anterior descending, 4 segments of circumflex artery, 3 segments of right coronary artery. A week-long rehabilitation training program with walking as the main content was performed after the operation, and all the cases were successfully completed. It shows that walking-based non-monitoring rehabilitation training is safe and feasible for patients with unstable angina pectoris after PTCA.
