Stroke Recovery Program with Modified Cardiac Rehabilitation Improves Mortality, Functional & Cardiovascular...

Physical activity and exercise after stroke is strongly recommended, providing many positive influences on function and secondary stroke prevention. The purpose of this study was to investigate the effect of a stroke recovery program (SRP) integrating modified cardiac rehabilitation on mortality and functional outcomes for stroke survivors.

This study used a retrospective analysis of data from a prospectively collected stroke rehabilitation database which followed 449 acute stroke survivors discharged from an inpatient rehabilitation facility between 2015 and 2020. For 1-year post-stroke, 246 SRP-participants and 203 nonparticipants were compared. The association of the SRP including modified cardiac rehabilitation with all-cause mortality and functional performance was assessed using the following statistical techniques: log rank test, Cox proportional hazard model and linear mixed effect models. Cardiovascular performance over 36 sessions of modified cardiac rehabilitation was assessed using linear effect model with Tukey procedure. The primary outcome measure was 1-year all-cause mortality rate. Secondary outcomes were functional performance measured in Activity Measure of Post-Acute Care scores and cardiovascular performance measured in metabolic equivalent of tasks times minutes.

The SRP-participants had: (1) a significantly reduced 1-year post-stroke mortality rate from hospital admission corresponding to a four-fold reduction in mortality (P = 0.005, CI for risk ratio = [0.08, 0.71]), (2) statistically and clinically significant improvement of function in all Activity Measure of Post-Acute Care domains (P < 0.001 for all, 95% CI for differences in Basic Mobility [5.9, 10.1], Daily Activity [6.2, 11.8], and Applied Cognitive [3.0, 6.8]) compared to the matched cohort and (3) an improvement in cardiovascular performance over 36 sessions with an increase of 78% metabolic equivalent of tasks times minutes (P < 0.001, 95% CI [70.6, 85.9%]) compared to baseline.

Stroke survivors who participated in a comprehensive stroke recovery program incorporating modified cardiac rehabilitation had decreased all-cause mortality, improved overall function, and improved cardiovascular performance.
