A large-scale cohort study of long-term cardiac rehabilitation: A prospective cross-sectional study
International Journal of Cardiology(2020)
摘要
Background
Few studies have evaluated the therapeutic effect of long-term cardiac rehabilitation (CR) and no large-scale survey of cardiovascular outcomes after long-term CR is reported.
Methods
This cohort study included 9981 patients undergoing CR from 2004 to 2015. Patients who had supervised CR were divided into three groups according to CR duration: up to acute phase (until discharge, Phase I group), up to recovery phase (≤150 days, Phase II group), and up to maintenance phase (>150 days, Phase III group). Using propensity score matching, mortality and major adverse cardiovascular events (MACE) were compared among the groups.
Results
Follow-up period was 4.9 ± 3.0 years. Adult patients were divided into three groups (Phase I group: n = 4649, Phase II group: n = 3271, and Phase III group: n = 731). After propensity score matching, the risk of death and MACE was extremely lower in Phase III group than in Phase I or Phase II group (death: HR 0.47, P < 0.01, HR 0.64, P < 0.01, and MACE: HR 0.48, P < 0.01, HR 0.70, P < 0.01). Most patients in Phase II group had better survival than those in Phase I group. Subpopulations of female patients and those with dyslipidemia, smoking history, coronary artery bypass graft, or heart failure had better survival in Phase III group than in Phase II group.
Conclusions
Long-term supervised CR for patients with cardiovascular diseases is more effective than short-term CR.
