CoQ10 May Improve Diabetics Heart Health

Diabetics are being increasingly encouraged to take cholesterol-reducing drugs called statins.  However, statins have been shown to deplete the body's natural stores of CoQ10, which increases the risk of developing heart disease and high blood pressure.
Diabetics receiving statins can improve their heart health by taking a CoQ10 supplement, according to a study published in the February 2009 issue of Diabetes Care.
The findings also indicate that CoQ10 supplementation may improve endothelial dysfunction in statin-treated type 2 diabetics.  Endothelial dysfunction results in the inability of arteries to dilate fully, and can lead to stroke and heart attacks.
Twenty-three statin-treated type 2 diabetic patients with endothelial dysfunction were recruited for the study.  Participants were randomly assigned to receive either CoQ10 or a placebo for 12 weeks.
The randomized, double-blind, crossover study analyzed flow-mediated dilation (FMD) and nitrate-mediated dilation (NMD).  A low value of FMD is indicative of a blood vessel's inability to relax.  NMD relates to the levels of nitric oxide (a potent relaxing factor) present in the blood vessels.
After 12 weeks, participants who had received the CoQ10 supplementation were found to have an increase of FMD of 1% and no changes in NMD.  Researchers state that this 1% improvement in blood flow may translate to a 10-25% reduction in cardiovascular risk for the participants.
Additional research has suggested CoQ10 supplementation would be beneficial for most people taking cholesterol lowering drugs to counteract the CoQ10 depletion that occurs.
There are many factors involved in maintaining a healthy heart, including eating a healthy diet, regular exercise, abstaining from smoking and lowering bad cholesterol levels. In addition, omega-3's have been shown to benefit heart health by decreasing the risk of arrhythmia, decreasing triglyceride levels and lowering blood pressure.
