The role of exercise training and dietary sodium restriction in heart failure rehabilitation: A systematic review.
Study Goal
The researchers aimed to determine the impact of dietary salt reduction, particularly to less than 1500 mg per day, on hospitalizations, emergency room visits, and overall mortality in heart failure patients.
Results Summary
Sodium restriction to less than 1500 mg per day did not significantly affect hospitalization rates, emergency room visits, or overall mortality compared to conventional treatment. However, combining sodium restriction with exercise training may enhance heart failure symptoms and clinical outcomes synergistically.

Heart failure (HF) rehabilitation seeks to enhance the entire well-being and quality of life of those with HF by focusing on both physical and mental health. Non-pharmacological measures, particularly exercise training, and dietary salt reduction, are essential components of heart failure rehabilitation. This study examines the impact of these components on the recovery of patients with heart failure. By conducting a comprehensive analysis of research articles published from 2010 to 2024, we examined seven relevant studies collected from sources that include PubMed and Cochrane reviews. Our findings indicate that engaging in physical activity leads to favorable modifications in the heart, including improved heart contractility, vasodilation, and cardiac output. These alterations enhance the delivery of oxygen to the peripheral tissues and reduce symptoms of heart failure, such as fatigue and difficulty breathing. Nevertheless, decreasing the consumption of salt in one's diet to less than 1500 mg per day did not have a substantial impact on the frequency of hospitalizations, visits to the emergency room, or overall mortality when compared to conventional treatment. The combination of sodium restriction and exercise training can have synergistic effects due to their complementary modes of action. Exercise improves cardiovascular health and skeletal muscle metabolism, while sodium restriction increases fluid balance and activates neurohormonal pathways. Therefore, the simultaneous usage of both applications may result in more significant enhancements in HF symptoms and clinical outcomes compared to using each program alone.
