Vitamin D deficiency linked to myocardial infarction

By David Liu, PHD

Sunday July 29, 2012 (foodconsumer.org) -- Having vitamin D deficiency or insufficiency may drastically increase myocardial infarction risk in men and coronary artery disease in both men and women with hypertension, according to a study published June 27, 2012 in the Open Cardiovascular Medicine Journal.

The study led by A. El-Meyyar of Weill Cornell Medical College in Doha, Qatar and colleagues found that of men and women who had low vitamin D, men were more likely than women to have diabetes mellitus, dyslipidemia, myocardial infarction, and angiographically documented coronary artery disease.

Of men and women with low vitamin D, those with hypertension were 8 times as likely as those without hypertension to develop coronary artery disease. 

The study was based on data collected retrospectively from Jan 2008 through Nov 2009. Overall, the mean level of vitamin D among 547 patients was 14.4 ng/mL.  In the study, more women than men suffered low vitamin D, but men were more susceptible to chronic diseases or conditions.

Vitamin D deficiency or insufficiency may be a risk factor for myocardial infarction, according to a paper published in MBC Research Notes in Dec 2011.

In the paper, J.B. Wetmore of University fo Kansas Medical Center in Kansas City, KS and colleagues wrote "Nutritional vitamin D deficiency is an emerging risk factor for acute myocardial infarction (AMI) and heart failure."

The researchers found 95.7 percent of acute myocardial infarction patients had low vitamin D or 25(OH)D.
