title: Coenzyme Q10: a new drug for myocardial ischemia?
abstract: A biochemical rationale for using CoQ in treating certain cardiovascular diseases has been established. CoQ subserves an endogenous function as an essential cofactor in several metabolic pathways, particularly oxidative respiration. As an exogenous source in supraphysiologic doses, CoQ may have pharmacologic effects that are beneficial to tissues rendered ischemic and then reperfused. Its mechanism of action appears to be that of a free radical scavenger and/or direct membrane stabilizer. Initial clinical studies performed abroad and in the United States indicate that CoQ may be effective in treating certain patients with ischemic heart disease, congestive heart failure, toxin-induced cardiotoxicity, and possibly hypertension. The most intriguing property of CoQ is its potential to protect and preserve ischemic myocardium during surgery. Currently, CoQ is still considered an experimental agent and only further studies will determine whether it will be useful therapy for human cardiovascular disease states.
