Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if vitamin D will improve physical performance in older adults with heart failure.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study is designed as a short pilot study which will assess safety and efficacy of high dose Vitamin D therapy in a heart failure population.

A 6 month randomized double blind placebo-controlled trial of 50,000 units of oral vitamin D3(cholecalciferol) weekly plus 800 calcium daily vs. weekly placebo plus 800 calcium alone in 64 heart failure (HF) patients \> 50 years old. This design was chosen over a cross-over design due to the long wash-out period for vitamin D.
