Orlando, FL - Inadequate levels of vitamin D are associated with an increase in the risk of cardiovascular disease and death, a new observational study has found. Dr Tami L Bair (Intermountain Medical Center, Murray, UT) reported the findings here at the American Heart Association 2009 Scientific Sessions.
Bair and colleagues followed more than 27 000 people 50 years or older with no history of cardiovascular disease for just over a year and found that those with very low levels of vitamin D (<15 ng />30 ng/mL). Those deficient in vitamin D were also twice as likely to develop heart failure as those with normal levels.
"We concluded that even a moderate deficiency of vitamin D was associated with developing coronary artery disease, heart failure, stroke, and death," said coauthor Dr Heidi May (Intermountain Medical Center). However, "it is not known whether this is a cause and effect relationship," she told heartwire. Because this study was observational, more research is needed "to better establish the association between vitamin D deficiency and cardiovascular disease," she noted."
