Exercise training improves exercise capacity and quality of life in heart failure with preserved ejection fraction: a systematic review and meta-analysis of randomized controlled trials.
Aims: Heart failure with preserved ejection fraction (HFpEF) is associated with high morbidity and mortality, and there are limited proven therapeutic strategies. Exercise has been shown to be beneficial in several studies. We aimed to evaluate the efficacy of exercise on functional, physiological, and quality-of-life measures.
Methods and results: A comprehensive search of Medline and Embase was performed. Randomized controlled trials (RCTs) of adult HFpEF patients with data on exercise intervention were included. Using meta-analysis, we produced pooled mean difference (MD) estimates with 95% confidence intervals (CIs) with Review Manager (RevMan) software for the peak oxygen uptake (VO2), Minnesota living with heart failure (MLWHF) and, other diastolic dysfunction scores. A total of 14 studies on 629 HFpEF patients were included (63.2% female) with a mean age of 68.1 years. Exercise was associated with a significant improvement in the peak VO2 (MD 1.96 mL/kg/min, 95% CI 1.25-2.68; P < 0.00001) and MLWHF score (MD -12.06, 95% CI -17.11 to -7.01; P < 0.00001) in HFpEF. Subgroup analysis showed a small but significant improvement in peak VO2 with high-intensity interval training (HIIT) vs. medium-intensity continuous exercise (MCT; MD 1.25 mL/kg/min, 95% CI 0.41-2.08, P = 0.003).
Conclusion: Exercise increases the exercise capacity and quality of life in HFpEF patients, and high-intensity exercise is associated with a small but statistically significant improvement in exercise capacity than moderate intensity. Further studies with larger participant populations and longer follow-up are needed to confirm these findings and elucidate potential differences between high- and medium-intensity exercise.
