Coenzyme Q10 on prescription?

Mother and daughter
We know that the body’s production of Coenzyme Q10 begins to decrease with age once we reach our 20’s, and we know that Coenzyme Q10 plays an important role in both cellular bio-energetics and antioxidant protection. It just makes sense to supplement our diets with Coenzyme Q10 in an attempt to avoid heart failure later on in life.

For as long as I have been writing this blog, I have been wondering why cardiologists are not prescribing Coenzyme Q10 for certain classes of heart disease patients.  Two classes of patients come to mind immediately: chronic heart failure patients and patients taking statin medications.  Let’s look at the evidence for heart failure patients. (We can talk about patients on statin medications next week.)

Coenzyme Q10 and chronic heart failure
Chronic heart failure.  Heart failure.  It sounds scary.  It is scary.  The words “heart failure” do not mean that the heart has stopped working.  What heart failure means is some combination of the following conditions:

  • The heart is weaker at pumping blood to deliver the needed oxygen and nutrients to the body’s other organs.
  • There is more pressure on the heart muscle.  The heart has to work harder and harder.
  • There is retention of fluid (called edema) in the feet and legs, arms, liver, intestine, and lungs (often referred to as congestive heart failure).
  • There is decreased quality of life: feeling tired, being short of breath, being able to walk only short distances, having difficulty breathing while lying down.

Extent of chronic heart failure in the United States
Between 5 and 6 million Americans suffer from chronic heart failure.  Half of the patients who develop chronic heart failure die within the next five years [Mozzafarian].  Adding up the costs of hospitalization and medical care, medications, and lost work days caused by heart failure leads to an estimate that heart failure costs the American society nearly 30 billion dollars a year [Heidenreich].  Each year.  Year after year.

If we could cut down the number of hospitalizations and re-hospitalizations and the length of the hospital stays and the number of adverse cardiovascular events by using Coenzyme Q10 as an adjunctive treatment for heart failure, then we could improve the quality of life for many older Americans, and we could reduce health care costs considerably.

Treatment of chronic heart failure with Coenzyme Q10
Conventional medical treatment, listed below, does not seem to overcome the heart failure patients’ problems with fatigue and inability to exercise.  What are these conventional treatments?

  • ACE inhibitors to lower blood pressure
  • Aldosterone antagonists to help remove excess sodium through the urine
  • Angiotensin receptor blockers to relax the blood vessels and to lower blood pressure
  • Beta blockers to slow the heart rate and to lower the blood
  • Digoxin to make the heart beat more powerfully
  • Diuretics to reduce fluid buildup in the lungs and feet and ankles

Adjuvant treatment with Coenzyme Q10
Treatment with Coenzyme Q10 in addition to conventional medical therapy has been shown to have the following beneficial health effects:

  • Reduces the incidence of cardiovascular death [Mortensen]
  • Reduces the need for mechanical support or heart transplant [Mortensen]
  • Reduces the need for hospitalization [Mortensen and Morisco]
  • Reduces the incidence of pulmonary edema (excess fluid in the lungs) and cardiac asthma [Morisco]

Treating the energy-starved heart with Coenzyme Q10
One theory about the underlying cause of heart failure is that the heart muscle is suffering from energy starvation.  The heart muscle cells are not producing enough energy.  Coenzyme Q10 has been shown to play a vital role in the production of energy in the cells [Littarru].

A second theory about the role of Coenzyme Q10 in preventing and alleviating heart disease is that Coenzyme Q10 functions as a powerful antioxidant neutralizing harmful free radicals in cell membrane lipids and in serum lipoproteins [Mohr].

A third theory about the role of Coenzyme Q10 in heart disease is that Coenzyme Q10 improves endothelial function.  The endothelium is the thin layer of cells on the inside of arteries.  The endothelium needs to stay smooth and pliable.  If its cells become hard and if plaque builds up on them, narrowing the passageway through the arteries, then the risk of heart disease increases considerably [Tsai].

Conclusion
Coenzyme Q10 has been shown to be safe, free of any dangerous interactions with other heart disease medications, and effective at improving the symptoms and survival of heart failure patients.  It is affordable.

There is no good reason not to take a good Coenzyme Q10 supplement starting in one’s 40s because we know that our bodies produce less Coenzyme Q10 as we get older.  And, honestly, if you are a heart failure patient or know someone who is, be sure to mention the Q-Symbio study to the cardiologist.

Surely it is time for cardiologists to add adjuvant treatment with Coenzyme Q10 to the guidelines for the treatment of chronic heart failure?

Next week, we need to look at the evidence for taking Coenzyme Q10 in conjunction with statin medications.

    Hi, I am taking Coenzyme Q10 already for 11 years,since I have been hospitalized for heart failure (I was 42).My EF was then around 25,today is 37 (last year check).I am of course following a medicine plan with Triatec,Metoprolol,Furix and Xarelto.But since than I am also taking daily 600mg Coenzyme Q10,together with many other supplement based on the study I made myself on the web (Taurine, Hawthorn,Arginine,Turmeric,Potassium, Magnesium,Resveratrol,Vitamin C,Vitamin D,Vitamin B complex) .I informed doctors ,but they seem not to aknowledge. I conduct quite a normal life, I just try to avoid very intense sport activities.I`ve never been fond of alchool and never smoked,but i like food and I am 10-15 kg overweight.If you need any testimonial or information about my use of Q10 let me know.I appreciate what you do informing about the positive effects,because I think it works.
