MONDAY, June 9 (HealthDay News) -- Vitamin D deficiency may increase the risk of heart attack in men, says a U.S. study.
Researchers at the Harvard School of Public Health and Brigham and Women's Hospital, Boston, analyzed medical records and blood samples from 454 men, aged 40 to 75, who had a nonfatal heart attack or fatal heart disease, and compared them to 900 men who had no history of cardiovascular disease.
