Effects of Cardiac Rehabilitation on Cognitive Function in Heart Failure: A Systematic Review and Meta-Analysis.

Ten were eligible for quantitative analyses.

Two pre-post cardiac rehabilitation studies (n=66) showed improved cognitive scores following cardiac rehabilitation (SMD=0.56; 95% CI, 0.21-0.91; p=0.002).

Sensitivity analyses suggested heterogeneity was influenced by methodological quality.

Three studies (n=190) found no significant additional benefit from beyond adjunctive therapies beyond standard cardiac rehabilitation (SMD=-0.26, 95% CI, -1.43-0.91, p=0.67).
