  • Title: Coenzyme Q versus hypertension: does CoQ decrease endothelial superoxide generation?
    Author: McCarty MF.
    Journal: Med Hypotheses; 1999 Oct; 53(4):300-4. PubMed ID: 10608264.
    Abstract:
    Reports from several research groups--including two small double-blind clinical studies--indicate that supplemental coenzyme Q10 (CoQ) is moderately effective as a treatment for hypertension, in humans and in animals. Its efficacy is associated with a decrease in total peripheral resistance, and appears to reflect a direct impact of CoQ on the vascular wall. A reasonable interpretation of these findings is that CoQ is acting as an antagonist of vascular superoxide--either scavenging it, or suppressing its synthesis. By improving the efficiency of shuttle mechanisms that transfer high-energy electrons from the cytoplasm to the mitochondrial respiratory chain, CoQ may decrease cytoplasmic NADH levels and thereby diminish the reductive power that drives superoxide synthesis in endothelium and vascular smooth muscle. If CoQ therapy does indeed lower vascular superoxide levels, it can be expected to decrease the atherothrombotic risk associated with hypertension, and may have broader utility in the management of disorders characterized by endotheliopathy.
