目的评价心肌梗死恢复期经皮冠状动脉介入治疗术(PCI)对患者近期及远期的临床效果。方法对30例首次心肌梗死患者,平均于发病5.8±2.7周行PCI,并于术前(3.0±2.9天)、术后(4.8±2.5天)及随访期(术后6.2±1.7月)进行平板运动试验,以观察PCI对运动耐量的作用。结果PCI组术后早期运动耐量、运动持续时间、最大心率及心率-血压乘积明显增高。PCI后随访期患者运动耐量、运动持续时间较术前明显增高,但最大心率及心率-血压乘积无明显变化。结论在心肌梗死恢复期,PCI能改善患者的近期及远期左室功能及提高运动耐量。
Objective To evaluate the clinical effect of percutaneous coronary intervention (PCI) on the short-term and long-term prognosis of patients with myocardial infarction. Methods Thirty patients with first myocardial infarction received PCI on average within 5.8 ± 2.7 weeks of onset and were performed preoperatively (3.0 ± 2.9 days), postoperatively (4.8 ± 2.5 days), and follow-up (6.2 ± 1.7 months postoperatively) Flat exercise test to observe the effect of PCI on exercise tolerance. Results The early postoperative exercise tolerance, exercise duration, maximum heart rate and heart rate - pressure product in PCI group were significantly higher than those in control group. After PCI, the patients with exercise tolerance and exercise duration were significantly higher than those before operation, but there was no significant change in maximum heart rate and heart rate-blood pressure product. Conclusion During the recovery of myocardial infarction, PCI can improve the short-term and long-term left ventricular function and improve exercise tolerance.
