Low Vitamin D linked to raised male heart attack risk
Low levels of vitamin D appear to be associated with an increase in the risk of heart attack in men, US researchers say.
They analysed medical records from 454 men who had a non-fatal heart attack and 900 men with no history of heart disease.
Men with vitamin D levels of 15ng per ml of blood or less had 2.4 times the risk of a heart attack than those with 30ng/ml of vitamin D or more.
The increased risk remained after adjustment for family history, BMI, alcohol consumption, physical activity and lipid levels.
