    Role of Coenzyme Q10 in Chronic Heart Failure, Angina, and Hypertension

    PURPOSE: Coenzyme Q10 (CoQ10) has a pathophysiologic role in many disease states. The purpose of this review is to provide recommendations regarding the safety, efficacy, and dosing of CoQ10 in the management of chronic heart failure (CHF), angina, and hypertension. DATA SOURCES: Literature pertaining to the safety and efficacy of CoQ10 specifically in cardiovascular indications was reviewed. We used relevant clinical trials, articles, reviews, and letters that were selected from a literature search of the MEDLINE database (1974-2000), Micromedex Healthcare Series, and the Natural Medicines Comprehensive Database. FINDINGS: Coenzyme Q10 administered orally has favorable actions in the described cardiovascular conditions and appears to be safe and well tolerated in the adult population. Issues concerning optimum target dosages, potential interactions, monitoring parameters, and the role of CoQ10 as a monotherapeutic agent need to be investigated further. Favorable effects of CoQ10 on ejection fraction, exercise tolerance, cardiac output, and stroke volume are demonstrated in the literature; thus, the use of CoQ10 as adjuvant therapy in patients with CHF may be supported. CONCLUSIONS: Coenzyme Q10 therapy in angina and hypertension cannot be substantiated until additional clinical trials demonstrate consistent beneficial effects. However, CoQ10 may be recommended as adjuvant therapy in selected patients with CHE At this time, CoQ10 should not be recommended as monotherapy or first-line therapy in any disease state.

    Genetic variation and nutrition in relation to coronary artery disease.

    There is evidence that coronary artery disease (CAD), hypertension, diabetes mellitus (DM) and hyperlipidemia develop due to interaction of genetic and environmental factors during transition from poverty to affluence. Rapid transition in diet and lifestyle factors may influence heritability of the variant phenotypes that are dependent on the nutrient environment for their expression. We are beginning to recognize the interaction of specific nutrients with the genetic code possessed by all nucleated cells. In the next millennium, the physician may be able to make nutrient intake recommendations not on physical characteristics but on the basis of the individual's phenotypic expression for health while suppressing his phenotypic expression for disease. We have demonstrated an increased susceptibility to CAD, diabetes, central obesity, hyperinsulinemia and lipoprotein(a) excess in Indians in younger age groups indicating a genetic predisposition to these problems due to interaction of gene and environment. Lipoprotein(a) is a genetic risk factor for CAD, diabetes and stroke and it is higher in South Indians than North Indians. Antioxidant vitamins, coenzyme Q10 and n-3 fatty acids may have a beneficial influence whereas linoleic acid, saturated fat and sugars may have adverse effects on phenotypic expression. There is significant evidence that genes are involved in determining enzymes, receptors, cofactors, structural components involved in regulation of blood pressure, the metabolism of lipids, lipoproteins and inflammatory and coagulation factors that are involved in determining an individual's risk. Majority of these genes are polymorphic. While some genes respond to nutritional modulation, others may not indicate any response.

    Effect of hydrosoluble coenzyme Q10 on blood pressures and insulin resistance in hypertensive patients with coronary artery disease.

    In a randomised, double-blind trial among patients receiving antihypertensive medication, the effects of the oral treatment with coenzyme Q10 (60 mg twice daily) were compared for 8 weeks in 30 (coenzyme Q10: group A) and 29 (B vitamin complex: group B) patients known to have essential hypertension and presenting with coronary artery disease (CAD). After 8 weeks of follow-up, the following indices were reduced in the coenzyme Q10 group: systolic and diastolic blood pressure, fasting and 2-h plasma insulin, glucose, triglycerides, lipid peroxides, malondialdehyde and diene conjugates. The following indices were increased: HDL-cholesterol, vitamins A, C, E and beta-carotene (all changes P<0.05). The only changes in the group taking the B vitamin complex were increases in vitamin C and beta-carotene (P<0.05). These findings indicate that treatment with coenzyme Q10 decreases blood pressure possibly by decreasing oxidative stress and insulin response in patients with known hypertension receiving conventional antihypertensive drugs.

    Coenzyme Q in cardiovascular disease.

    Coenzyme Q10 or ubiquinone normally present in many plant and animal cells is an antioxidant. Coenzyme Q10 deficiency has been observed in patients with congestive heart failure, angina pectoris, coronary artery disease, cardiomyopathy, hypertension, mitral valve prolapse and after coronary revascularization. Coenzyme Q10 is involved in the synthesis of ATP and hence is useful in preventing cellular damage during ischaemia-reperfusion injury. The clinical benefits are mainly due to its ability to improve energy production, antioxidant activity, and membrane stabilizing properties. Several studies showed that coenzyme Q could be useful in patients with congestive heart failure, angina pectoris, cardiomyopathy, coronary artery disease and in the preservation of myocardium. Coenzyme Q10 is normally present in the low density lipoprotein cholesterol fraction and inhibits its oxidation. It can also regenerate vitamin E. Coenzyme Q10 is known for producing minor gastrointestinal discomfort and elevation in SGOT and LDH when used.

    What happens if you take too much COQ10? i only have 100mg caplets here at home, and the recommended dosage is 60mg/day....

    It won't hurt you. In various studies they used dosaes as high as 1000mg. It's an enzyme needed for the body to make ATP (muscle energy). I usually pop a couple 150 mg tablets an hour or so before my work out.
