Key result
An improvement of 5% in predicted cardiovascular fitness following cardiac rehabilitation was associated with a 10% reduced risk of cardiac hospitalization or all-cause mortality (P<0.001).

Does improvement in cardiovascular fitness reduce the risk of cardiac hospitalisation or all-cause mortality in heart failure patients participating in a cardiac rehabilitation programme?
Effect estimate: 10% reduced risk
p-value: p=<0.001
In heart failure patients, improving cardiovascular fitness through cardiac rehabilitation is associated with a reduced risk of mortality or cardiac hospitalization, regardless of baseline fitness levels.
Sabbag et al. (2018) conducted a cohort in Heart failure (n=421). Cardiac rehabilitation program (improvement in cardiovascular fitness) vs. Lower degree of functional improvement was evaluated on Cardiac hospitalisation or all-cause mortality (10% reduced risk, p=<0.001). An improvement of 5% in predicted cardiovascular fitness following cardiac rehabilitation was associated with a 10% reduced risk of cardiac hospitalization or all-cause mortality (P<0.001).
