Heart disease, stroke, heart failure, and premature death all linked to insufficient vitamin D levels
The results of a study presented on November 16, 2009 at the American Heart Association's Scientific Conference in Orlando, Florida, confirmed a strong association between the presence of reduced vitamin D levels and a greater risk of coronary artery disease, stroke, heart failure and dying over follow-up in men and women 50 years of age and older.
Brent Muhlestein, MD and his colleagues at Intermountain Medical Center in Salt Lake City followed 27,686 subjects with no history of heart disease for an average of 1.2 years. Serum 25-hydroxyvitamin D levels obtained during routine clinical care were classified as normal at over 30 nanograms per milliliter (ng/mL), low at between 15 to 30 ng/mL or very low at less than 15 ng/mL.
