Vit D deficiency linked to increased CV risk

According to a study conducted by scientists at the Harvard Medical School in Boston, USA, people with low vitamin D levels are at an increased risk of heart attack, heart failure and stroke. The research also showed this risk is particularly acute in individuals suffering from high blood pressure.

Vit D below 15ng/ml raises MI risk

The study team, led by Thomas Wang, evaluated data from 1,739 people, collecting regular blood samples over a period of five years to monitor variation in vitamin D concentration. The results, published in the American Heart Association's journal Circulation, showed that in individuals with reduced vitamin D levels, those below 15ng/ml, the risk of a cardiovascular event was 50% higher than in subjects in whom vitamin D levels were well above the 15ng/ml threshold.
