Insights
Vitamin D supplementation significantly improved heart failure (HF) outcomes. Patients showed reduced pro-brain natriuretic peptide and C-reactive protein levels, alongside enhanced functional capacity and New York Heart Association class.
Area of Science:
- Cardiology
- Endocrinology
- Nutritional Science
Background:
- Heart failure (HF) is a complex syndrome often associated with vitamin D deficiency.
- Low vitamin D levels are prevalent in HF patients, impacting disease severity and prognosis.
Purpose of the Study:
- To assess the efficacy of vitamin D supplementation in improving biochemical markers and functional capacity in heart failure patients.
- To investigate the impact of vitamin D3 (cholecalciferol) on patients with New York Heart Association (NYHA) class I-III heart failure.
Main Methods:
- A prospective study involving 100 HF patients with low 25-hydroxyvitamin D levels.
- Patients received oral vitamin D3 for 4 months, with pre- and post-supplementation measurements of vitamin D, pro-brain natriuretic peptide, high-sensitivity C-reactive protein, NYHA class, and 6-minute walk distance.
Main Results:
- Vitamin D supplementation significantly increased serum 25-hydroxyvitamin D levels (P<.001).
- Pro-brain natriuretic peptide and high-sensitivity C-reactive protein levels decreased significantly (P<.001).
- Substantial improvements were observed in NYHA class and 6-minute walk distance (P<.001).
Conclusions:
- Vitamin D supplementation is effective in improving biochemical markers and functional capacity in heart failure patients.
- Restoring vitamin D levels may be a beneficial therapeutic strategy for managing heart failure.
Abstract:
The aim of the present study was to investigate whether vitamin D supplementation could improve biochemical findings and functional capacity of patients with heart failure (HF). One hundred patients with New York Heart Association (NYHA) class I through III HF were included in this prospective study and their 25-hydroxyvitamin D levels were evaluated. Only 6% of the participants had a sufficient serum concentration of 25(OH) D >30 nmol/L. Patients with insufficient or deficient serum levels of 25(OH) D (<30 ng/mL and <20 ng/mL, respectively) received oral vitamin D3 (cholecalciferol) for a total period of 4 months. Vitamin D supplementation increased mean serum concentration of 25(OH) D from 12.63±7.60 nmol/L to 54.49±18.01 nmol/L (P<.001). After vitamin D supplementation, the serum level of pro-brain natriuretic peptide markedly decreased (P<.001). Cholecalciferol significantly decreased high-sensitivity C-reactive protein level (P<.001). Restoration of serum 25(OH) D level was also associated with substantial improvement in NYHA class (P<.001) and 6-minute walk distance (P<.001).
