The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

Statin treatment may lead to heart failure

The author of this paper, Dr. Peter Langsjoen is a specialist in Coenzyme Q10 and cardiology. Dr Langsjoen has authored many papers outlining Coenzyme Q10 deficiency as a factor in heart disease. Dr Langsjoen's papers have demonstrated the association of advanced congestive heart failure with low blood levels of Coenzyme Q10 and shown, unequivocally, that replenishing Coenzyme Q10 dramatically helps the failing heart.

In this review of the scientific literature, Dr Langsjoen found:
(a) The depletion of the essential nutrient Coenzyme Q10 by the increasingly popular cholesterol lowering drugs, statins, has grown from a level of concern to one of alarm.
(b) With ever higher statin potencies and dosages, and with a steadily shrinking target levels of low density lipoprotein (LDL) cholesterol, the prevalence and severity of Coenzyme Q10 deficiency is increasing noticeably.
(c) Statin-induced Coenzyme Q10 depletion is well documented in animal and human studies with detrimental cardiac consequences in both animal models and human trials.
(d) This drug-induced nutrient deficiency is dose related and more notable in settings of pre-existing Coenzyme Q10 deficiency such as in the elderly and in heart failure.

Dr Langsjoen's review reveals that statins cause a deficiency in Coenzyme Q10 levels, and that low Coenzyme Q10 levels are associated with increased rates of heart failure.

Dr Langsjoen concludes: "We are currently in the midst of a congestive heart failure epidemic in the United States.....As physicians, it is our duty to be absolutely certain that we are not inadvertently doing harm to our patients by creating a wide-spread deficiency of a nutrient critically important for normal heart function".
