Exercise reduces blood pressure after stroke or TIA: systematic review and meta-analysis
This systematic review and meta-analysis of 25 studies examined the effect of exercise on blood pressure in individuals after stroke or transient ischemic attack. The interventions included aerobic, resistance, and combined aerobic and resistance training. The primary outcomes were systolic and diastolic blood pressure reductions.
Aerobic exercise alone reduced systolic blood pressure by 3.79 mmHg (95% CrI: -5.95, -1.86) and diastolic blood pressure by 1.91 mmHg (95% CrI: -3.56, -0.33). Combined aerobic and resistance training produced larger reductions: systolic blood pressure decreased by 7 mmHg (95% CrI: -10.05, -3.87) and diastolic by 3.58 mmHg (95% CrI: -6.04, -1.23).
The authors note that these findings support evidence-based exercise prescriptions for blood pressure management in this high-risk population. However, limitations such as potential heterogeneity among studies and lack of reported adverse events should be considered. The meta-analysis provides quantitative estimates that can guide clinical recommendations, but individual patient factors and exercise tolerance must be taken into account.
