Effect of Vitamin Supplementation in Patients of Congestive Heart Failure Deficient in Vitamin D: A Study at a Tertiary Care Center of North India

INTRODUCTION: Heart Failure is a leading cause of mortality worldwide including India. Most cross sectional studies have demonstrated heart failure is associated with deficiency of essential micronutrients including Vitamin D which may play a important role in pathogenesis of ventricular remodelling in heart failure. AIM: Our study performed aimed to determine the effect of supplementation in patients of Heart Failure presenting with Vitamin D deficiency to our institute on severity of Heart Failure. DESIGN AND METHOD: 97 patients of Heart failure coming to our institute were given conventional therapies for Heart Failure along with Vitamin supplementation based on serum Vitamin D levels and followed up for 3 months. RESULTS: Patient of Heart failure having Vitamin D deficiency had significant reduction in cardiac biomarkers (NT-pro BNP levels), improvement in Left ventricular ejection fraction (LVEF) and more favourable reverse remodelling determined by Left ventricular end diastolic and systolic diameter (LVEDD & LVESD) though quality of life determined by WHODAS 2.0 score did not changed following 12 weeks supplementation of High Dose Vitamin D. CONCLUSION: Recognising and treatment of Vitamin D deficiency may determine long term prognosis in patients of Heart Failure.
