Vitamin D Deficiency May Be Linked to Heart Disease
Latest Heart News
THURSDAY, March 27, 2014 (HealthDay News) -- New research suggests people with lower levels of vitamin D are more likely to suffer from coronary artery disease and to have more severe forms of the illness.
The results "suggest vitamin D deficiency to be the cause rather than the consequence of atherosclerosis," said study investigator Dr. Monica Verdoia, a cardiologist at Eastern Piedmont University in Novara, Italy. Clogged arteries, or atherosclerosis, can lead to heart attack.
The findings are scheduled for presentation Sunday at the American College of Cardiology's annual meeting in Washington, D.C.
Researchers who examined nearly 1,500 patients found that 70 percent of those undergoing angiography, a test used to detect blockages in the arteries, had deficient levels of vitamin D.
Patients with levels low enough to be considered deficient had a 32 percent greater risk of coronary artery disease and an almost 20 percent greater risk of the most severe level of disease, the researchers said in a college news release.
Also, those with the lowest levels of vitamin D were almost twice as likely to suffer from clogged arteries compared to those with normal levels.
More than half of U.S. adults, especially blacks and Hispanics, get too little vitamin D, according to the news release.
Vitamin D is absorbed through the skin from sunlight. It is also found in fatty fish, fortified dairy products and supplements.
"Although evidence of benefits with vitamin D supplementation in cardiovascular outcomes are still lacking, strategies to raise [natural] vitamin D should probably be advised in the prevention of cardiovascular disease," she said in the news release.
Data and conclusions presented at meetings are typically considered preliminary until published in a peer-reviewed medical journal.
