Vitamin D3 Supplementation for Heart Failure Patients

Completed · Phase 2 · Has a placebo group

Conditions studied: Heart Failure, Vitamin D Deficiency, Cardiomyopathy, Congestive Heart Failure

In brief

The purpose of this study is to determine if treatment with vitamin D3 of 10,000 International Units (IU) daily in vitamin D deficient patients for 6 months will improve B type natriuretic peptide (BNP), a marker of heart function, compared to placebo. The investigators also aim to determine if vitamin D helps cardiopulmonary function as evaluated by cardiopulmonary exercise test (CPX), laboratory values, strength, and quality of life in patients with stable congestive heart failure (Class II or III).
