Can coenzyme Q10 help treat heart disease?

Dr. Peter Bongiorno, ND
Naturopathic Medicine
Clinical studies have shown that the oral administration of Coenzyme Q10 (CoQ10) improves the health of patients suffering from heart problems.

An analysis of heart muscle tissue collected from patients with heart disease revealed a marked decrease in the tissue CoQ10 concentration.

It has been shown that patients with lower ubiquinol (an active form of CoQ10, which has been shown to have quite powerful antioxidant potential) concentrations and decreases in ATP (energy) production in the heart muscle tissue suffered more severe types of heart disease than patients with higher levels of CoQ10.

Clinical trials of patients with a severe form of heart disease called congestive heart failure were given 580 mg per day of ubiquinone. These patients found significant increases in blood levels of CoQ10 levels, along with excellent improvements in the ejection fraction of the heart (the heart's ability to move blood) and improvement of the left ventricle, the part of the heart that sends blood out to the body.

There is also some preliminary research evidence that suggests coenzyme Q10 may be helpful in cardiac arrhythmias, a type of heart issue where the heartbeat can become too fast or erratic.
