Vitamin D and heart disease

Sep 02, 2016

This was a relatively small study conducted in men with ‘heart failure’ and published in the Journal of the American College of Cardiology.

The study found that supplementation with Vit D3 improved the pump function of the heart as measured with echocardiography but did not improve symptoms or the distance walked. These findings are intriguing but do not make the case for a change in routine care - I do think that we will all be measuring vitamin D levels a little more frequently though.

There is also an association between Vit D levels and cardiovascular disease ie that those with low levels of the vitamin tend to have higher rates of hypertension, heart attacks and strokes. For example, those lucky enough to have one holiday a year in the sunshine over 3 decades have a lower risk of developing the above complications. We have no evidence that supplementing Vit D levels actually reduces the vascular events so the we cannot prove for certain that the link is causal. Rather than taking pills, the sensible advice seems to be that giving yourself moderate exposure to sunlight is a good thing and should be encouraged for a number of reasons!
