Abstract
Objective: This study aims to systematically analyze the impact of exercise-based cardiac rehabilitation on patients undergoing percutaneous coronary intervention (PCI). Methods: We searched for original studies on the effect of exercise-based cardiac rehabilitation on patients undergoing PCI published in domestic and foreign databases such as PubMed, Web of Science, Embase, Cochrane Library, China Knowledge Network (CNKI), and VIP until December 2023. Studies retrieved were screened, and meta-analysis was extracted. The quality of the literature was evaluated; meta-analysis was carried out by RevMan5.4 software (Cochrane Collaboration, Oxford, UK). Results: A total of 1073 sufferers undergoing PCI were included in 11 literatures. Meta-analysis displayed that cardiogenic mortality [risk ratio (RR) = 0.23, 95% confidence interval (CI) (0.08, 0.64)], coronary restenosis rate [RR = 0.59, 95% CI (0.41, 0.87)], revascularization rate [RR = 0.58, 95% CI (0.43, 0.79)], incidence of recurrent angina pectoris [RR = 0.41, 95% CI (0.27, 0.62)], and late lumen loss [RR = –0.60, 95% CI (–0.98, –0.23)] in the trial group, were lower than those in the control group (p < 0.05). No significant difference was found in the recurrence rate of myocardial infarction between the test group and the control group [RR = 0.52, 95% CI (0.22, 1.25)]. Conclusion: Exercise-based cardiac rehabilitation therapy can effectively reduce the risk of major adverse cardio-cerebrovascular events, such as cardiogenic death and coronary restenosis after PCI; it reduces the late lumen loss of the stent coronary segment and has no obvious effect on the recurrence of myocardial infarction. However, this therapy tends to reduce the recurrence rate of myocardial infarction.
