Background. The optimal exercise prescription for coronary artery disease (CAD) remains under debate. The aim of our meta-analysis is to investigate the efficacy of high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) of coronary artery disease patients. Methods. Electronic databases were searched from their inception date until October 23, 2021, and the articles include randomized controlled trials. The mean differences and 95% confidence intervals were calculated, and heterogeneity was assessed using the I² test. Results. The study standards were met by seventeen studies. The pooled studies included 902 patients. HIIT resulted in improvement in peak oxygen uptake (1.50 ml/kg/min, 95% confidence interval: 0.48 to 2.53, n = 853 patients, and low quality evidence) compared with MICT. There was no discernible difference between the individuals in the HIIT group and the MICT group in terms of systolic/diastolic blood pressure or peak/resting heart rate. Conclusion. This systematic review and meta-analysis reported the superiority of HIIT versus MICT in enhancing peak oxygen uptake in CAD patients.

高强度间歇训练对冠状动脉疾病患者运动能力的影响：系统评价和荟萃分析

背景。冠状动脉疾病 (CAD) 的最佳运动处方仍在争论中。我们的荟萃分析的目的是研究冠心病患者高强度间歇训练 (HIIT) 与中等强度连续训练 (MICT) 的疗效。方法。电子数据库从开始日期到 2021 年 10 月 23 日进行了搜索，文章包括随机对照试验。计算平均差异和 95% 置信区间，并使用I ²检验评估异质性。结果. 十七项研究符合研究标准。汇总研究包括 902 名患者。 与 MICT 相比，HIIT 改善了峰值摄氧量（1.50 ml/kg/min，95% 置信区间：0.48 至 2.53，n = 853 名患者，证据质量低）。HIIT 组和 MICT 组的个体在收缩压/舒张压或峰值/静息心率方面没有明显差异。结论。该系统回顾和荟萃分析报告了 HIIT 与 MICT 在提高 CAD 患者的峰值摄氧量方面的优势。
