Abstract

Background: Exercise-based cardiac rehabilitation (CR) programs are recommended in outpatients at least three times a week, but high-frequency visits can be difficult due to patients' work schedules. The association between the frequency of exercise-based CR and the increase in exercise tolerance is not well known. We evaluated the effect of CR once a week or more for improving exercise tolerance.

Methods: This is a retrospective observational study. From February 2011 to January 2020, 110 outpatients who participated in CR and performed a cardiopulmonary exercise test (CPET) two times (initially and within 6 months) were registered. We divided the patients into those who participated in CR once a week or more (n = 75) and less than once a week (n = 35) and compared the changes in the results of CPET.

Results: Overall, the median patient age was 68.5 (59-74) years, 69.1% were males, and the body mass index was 23.8 (20.2-27.4) kg/m². The average frequency of CR was 1.54 (0.93-1.89) times per week. While patients who participated in CR once a week or more showed improvements in oxygen uptake, ventilatory equivalent, ventilatory efficiency, and oxygen uptake per heart rate, those who participated in CR less than once a week showed only small improvements. The ratio of oxygen uptake to work rate in patients who participated in CR once a week or more also improved significantly.

Conclusions: Patients who participated in a CR program once a week or more showed improved exercise tolerance.

坚持心脏康复计划可提高心血管疾病门诊患者的运动耐受性。

背景：建议门诊患者每周至少进行三次基于运动的心脏康复（CR）计划，但由于患者的工作安排，高频率就诊可能很困难。基于运动的CR频率与运动耐受性增加之间的关系尚不清楚。我们评估了每周一次或更多次的CR对改善运动耐受性的影响。方法：回顾性观察性研究。从2011年2月到2020年1月，登记110例参加CR并进行两次心肺运动试验（CPET）的门诊患者（最初和6个月内）。我们将患者分为每周一次或更多的CR组（n = 75）和每周一次以下的CR组（n = 35），并比较CPET结果的变化。结果：总体而言，患者中位年龄为68.5（59 ~ 74）岁，男性占69.1%，体重指数为23.8 (20.2 ~ 27.4)kg/m2。CR平均频次为1.54（0.93 ~ 1.89）次/周。虽然每周一次或更多次参加CR的患者在摄氧量、通气当量、通气效率和每心率摄氧量方面均有改善，但那些参加CR少于每周一次的患者仅显示出微小的改善。每周一次或更多次参加CR的患者的摄氧量与工作率之比也显著改善。结论：每周一次或更多次参加CR计划的患者表现出更好的运动耐受性。
