Does endurance and resistance training improve functional capacity, quality of life, and cardiovascular outcomes in adult patients with HFrEF?
Structured exercise training is a valuable non-pharmacological intervention that improves functional capacity, quality of life, and potentially clinical outcomes in patients with HFrEF.

Heart failure with reduced ejection fraction (HFrEF) markedly impairs quality of life (QoL) and life expectancy. The main therapeutic goals are to reduce mortality, improve functional capacity, and enhance QoL. Exercise training is an evidence-based, non-pharmacological component of standard care that improves functional capacity and clinical outcomes in HFrEF. This review examines the effects of endurance and resistance training on peak oxygen uptake (VOpeak), ventilatory efficiency (VE/VCO slope), health-related QoL, and cardiovascular outcomes in patients with HFrEF. : A structured narrative review was conducted using comprehensive searches of PubMed, EMBASE, and the Cochrane Library for English-language studies published between January 2004 and October 2024. Eligible studies included adult HFrEF populations undergoing aerobic and/or resistance training with reported effects on VOpeak, ventilatory efficiency, QoL, or clinical outcomes. Given the heterogeneity of interventions, comparators, and outcome metrics, data were synthesized descriptively. : Across 18 studies (plus one sub-analysis) including 3401 patients, 17 trials assessed VOpeak and 16 reported significant improvements, with an average increase of approximately 2 mL·kg·min. Six studies assessed ventilatory efficiency, and five demonstrated reductions in VE/VCO slope averaging 4.4 units. Eleven studies analyzed QoL, and nine reported significant improvements corresponding to an ≈5-point decrease in the Minnesota Living with Heart Failure Questionnaire (MLHFQ). In the largest trial, exercise training was associated with modest but statistically significant reductions in all-cause mortality or hospitalization (HR 0.89) and cardiovascular mortality or heart-failure hospitalization (HR 0.85) after adjustment for baseline prognostic factors. : Structured exercise training improves aerobic capacity, ventilatory efficiency, and QoL in patients with HFrEF, with supportive evidence for reduced morbidity and mortality. These findings underscore the value of structured exercise as a core component of modern HFrEF management.
