The Importance of COQ10 in Improving Hypertension and Preventing Heart Failure

April 20, 2011

Coenzyme Q10 (CoQ10) is a compound found naturally in the energy-producing centre of the cell known as the mitochondria. CoQ10 is involved in making an important molecule known as adenosine triphosphate (ATP) which serves as the cell’s major energy source and drives a number of biological processes, including muscle contraction and the production of protein. It is a very popular supplement in the UK, partly for its ability to boost energy, enhance the immune system, and as an antioxidant.

Clinical research reported in the journal Biofactors has now indicated that patients with congestive heart failure that were supplemented with the active form of coenzyme Q10 (ubiquinol) improved ejection fraction by 39%. Ejection fraction is a critical marker of heart function used to determine the volume of blood pumped by the heart through the vascular system. CoQ10 is essential to convert nutrients to energy and power the cellular engine, and natural production in the body declines with age.

The study conducted at the East Texas Medical Center focused on patients with advanced congestive heart failure that were classified as Stage IV, the most severe form of the disease. Patients were supplemented with 580 mg of the ubiquinol form of coenzyme Q10 daily to increase plasma blood levels by a factor of four.

The researchers found “the improvement in plasma CoQ10 levels is correlated with both clinical improvement and improvement in measurement of left ventricular function.” Prior to CoQ10 supplementation, most of the participants were considered critically ill and confined to bed or a wheel chair. After being given ubiquinol, patients typically improved to the point they were able to carry on a productive lifestyle.

This is a serious problem that affects as many as one in three adults and high blood pressure is closely associated with coronary artery closure due to plaque formation and arterial stiffening as the normally elastic vessels require more pressure to fully circulate blood to the body. The result of a study published in the journal Nutrition and Metabolism found that coenzyme Q10 supplemented along with other potent antioxidant nutrients (vitamin C, vitamin E, and selenium) significantly increased small and large arterial elasticity that led to lower blood pressure and risk of a heart attack.

Subjects in this study received 60 mg of CoQ10 for a period of six months along with moderate amounts of the other nutrients. In addition to improved arterial elasticity, researchers found a significant decline in HbA1C blood sugar levels and an increase in protective HDL cholesterol levels. The authors of the research concluded that the CoQ10 nutrient antioxidant cocktail “has beneficial effect on glucose and lipid metabolism, blood pressure and arterial compliance in patients with multiple cardiovascular risk factors.”

Or in other words, they made a real difference to the patients’ health.
