Clinical Report: Comparative Analysis of Exercise Types and Their Impact on LVEF
Overview
This systematic review and network meta-analysis evaluated the effects of various exercise modalities on left ventricular ejection fraction (LVEF) in heart failure patients. Resistance training emerged as the most effective modality, particularly at low-to-moderate doses, suggesting a need for tailored rehabilitation strategies.
Background
Heart failure (HF) is a significant public health issue characterized by impaired cardiac function and poor prognosis. LVEF is a critical measure of cardiac performance and is essential for assessing HF severity. Despite advancements in pharmacological treatments, non-pharmacological interventions like exercise rehabilitation are vital for improving patient outcomes.

Key Findings
All exercise modalities significantly improved LVEF compared to control.
Resistance training had the largest treatment effect on LVEF.
The optimal dosage for LVEF improvement was identified as 500–800 MET-minutes/week.
HIIT required higher thresholds for optimal benefits compared to resistance training.
Evidence certainty for comparisons varied from very low to moderate.
Clinical Implications
Healthcare professionals should prioritize resistance training in exercise rehabilitation programs for heart failure patients, especially at low-to-moderate doses. Tailoring exercise prescriptions based on individual patient needs and responses can optimize cardiac function and improve overall outcomes.
Conclusion
Resistance training is the most effective exercise modality for enhancing LVEF in heart failure patients, underscoring the importance of individualized rehabilitation strategies.
In a target-trial emulation of more than 600,000 veterans, GLP-1 RA initiators saw fewer new substance use disorders—and patients with existing SUDs had fewer overdoses, hospitalizations, and deaths.
