|HEART ATTACKS AND VITAMIN D|
June 9 2008 Archives of Internal Medicine
It's getting harder and harder to ignore how much vitamin D status impacts heart disease. In this study men with low levels of vitamin D were shown to have an elevated risk for a heart attack. Men categorized as deficient in vitamin D were about 2.5x more likely to have a heart attack than those with higher levels of the vitamin. "Those with low vitamin D, on top of just being at higher risk for heart attack in general, were at particularly high risk to have a fatal heart attack," study author Dr. Edward Giovannucci.
The study looked at 454 health professionals ages 40 to 75 who had suffered a nonfatal heart attack or died of heart disease, as well as 900 other men with no history of cardiovascular disease. They were followed for 10 years after providing blood samples to measure their vitamin D levels. Those who were deficient in vitamin D -- no more than 15 nanograms per milliliter of blood - were compared to men who were in at least the lower end of the normal range -- at least 30 nanograms per milliliter of blood.
This new study complements the report in January 2008 by researchers at Harvard Medical School. They reported that people with low vitamin D levels have a higher risk for heart attack, heart failure and stroke.
