New study shows low vitamin D levels may relate to more severe coronary artery disease

Researchers presenting at the American College of Cardiology have found that vitamin D deficiency is related to risk and severity of coronary artery disease.

Coronary artery disease occurs when there is a build-up of plaque in the arteries that supply blood and oxygen to the heart.

The researchers examined the vitamin D levels of 1,484 patients who were in the hospital for a coronary angiography. Coronary angiography is a test used to determine how well blood is flowing through arteries in the body.

They found that 70.4% of the patients were deficient in vitamin D. The researchers also found that coronary artery disease was 32% more common among patients with the lowest vitamin D levels. Vitamin D deficiency was also related to a 20% higher frequency of severe coronary artery disease.

“Although evidence of benefits with vitamin D supplementation in cardiovascular outcomes are still lacking, strategies to raise endogenous vitamin D should probably be advised in the prevention of cardiovascular disease,” said researcher Dr. Monica Verdoia.

The researchers plan to conduct multiple clinical trials to see if treating vitamin D deficiency reduces the risk of developing atherosclerosis.

    That prickly cactus heart might be rich in antioxidants…but (alas) no vitamin D there….

    It is a tasty delicacy, however! And although no D, it is quite good for our hearts (barbs removed, of course) <3
