Serum 25-Hydroxyvitamin D Concentration and Mortality from Heart Failure and Cardiovascular Disease, and Premature Mortality from All-Cause in United States Adults

We aimed to examine associations between serum 25-hydroxyvitamin D (25[OH]D) concentration and mortality from heart failure (HF) and cardiovascular disease (CVD) and premature death from all causes using data from the Third National Health and Nutrition Examination Survey, which included 13,131 participants (6,130 men, 7,001 women) ≥35 years old at baseline (1988 to 1994) and followed through December 2000.
