Background
Cardiac rehabilitation is an important part of the therapeutic regimen for chronic heart failure. Acute decompensated heart failure (ADHF) in hospitalized patients were usually excluded from cardiac rehabilitation programs. The initiation of cardiac rehabilitation with ADHF usually occurs after hospital discharge. This study included recent clinical trials in patients beginning early exercise-based rehabilitation during their hospitalization and compared the efficacy and safety of early cardiac rehabilitation to ADHF patients who didn't receive cardiac rehabilitation.
Methods
Clinical trials were searched from the EMBASE, PubMed, CENTRAL, and WAN FANG. We included randomized controlled trials (RCTs) in which early exercise-based rehabilitation started during the index hospitalization, from the establishment of the database to July 2022. RevMan 5.4 was used for the statistical analysis.
Results
Six studies, with a total of 668 patients were included; 336 patients in the early rehabilitation group and 332 patients in the control group. Exercise capacity was significantly improved in the 6-minute walk distance [mean difference (MD): 32.97, 95% CI: 31.03 to 34.90, p < 0.00001], and the Short Physical Performance Battery (MD: 1.40, 95% CI: 1.35 to 1.44, p < 0.00001). The rate of all-cause rehospitalization was significantly decreased in the early rehabilitation group (OR: 0.67, 95% CI: 0.45 to 0.99, p = 0.04).
Conclusions
Early exercise-based rehabilitation for eligible ADHF in-patients starting during, or early after, hospitalization could significantly improve exercise capacity. A transitional, individualized, progressive, exercise-based rehabilitation program during hospitalization combined with post-discharge clinic rehabilitation is an integrated rehabilitation strategy for acute decompensated heart failure.
