Men with low concentrations of vitamin D have higher risk of heart attack

3:03pm, June 9, 2008

The good news just keeps on coming for vitamin D. A new study of men finds that getting plenty of vitamin D seems to lessen the risk of having a heart attack.

Researchers tracked the effect of vitamin D levels in blood by testing blood samples collected from 1993 to 1995 from more than 18,000 men who were part of a long-term study of physicians. Researchers then monitored these men for 10 years. By analyzing the initial blood vitamin D readings with the men’s subsequent health history, researchers were able to assess whether vitamin D status affected heart attack risk.

The researchers found that 454 men had heart attacks during the 10-year period that followed. Men with the least vitamin D were twice as likely to have a heart attack as men with the most, says Edward Giovannucci of the Harvard School of Public Health in Boston. He and his colleagues report the data in the June 9 Archives of Internal Medicine.
