Aerobic exercise-based cardiac rehabilitation in Chinese patients with coronary heart disease: study protocol for a pilot randomized controlled trial
Abstract
Abstract Background Cardiovascular disease is the leading cause of morbidity and mortality in the world, including China. Cardiac rehabilitation (CR) has been demonstrated to be beneficial in reducing cardiovascular mortality, myocardial infarction, and cerebrovascular events. This pilot study seeks to assess the feasibility of aerobic-exercise-based CR in Chinese patients with coronary heart disease (CHD) and outcomes of aerobic metabolism capacity and molecular biomarkers. Methods/design This study is a single-center, pilot, randomized, controlled study that is currently being carried out at a regional hospital in Shanghai. Forty patients with CHD who underwent percutaneous coronary intervention will be randomly allocated into either the intervention group or control group. Participants in the intervention group will undergo 8 weeks of aerobic exercise with targeted intensity and participants in the control group will undergo 8 weeks of leisure exercise. The primary measurement is the feasibility of the trial; the secondary measurement is the capacity of aerobic metabolism and the exploratory measurement includes additional molecular biomarkers underlying cardiovascular function. Discussion This is the first prospective randomized and controlled clinical study in China that assesses the parameters of aerobic metabolism and comprehensively screens for substantial blood biomarkers to reveal the molecular mechanisms underlying changes in cardiovascular function after aerobic exercise with targeted intensity in participants with CHD. The success of this study will contribute to guide the design of future CR studies in patients with CHD in China. Trial registration Chinese Clinical Trial Registry, ChiCTR-IPR-17010556.
