Abstract

BACKGROUND: Heart failure is one of the leading causes of mortality, is a final common pathway of several cardiovascular diseases, and its treatment is a major concern in the science of cardiology. The aim of the present study was to compare the effect of addition of the coenzyme Q10 (CoQ10)/atorvastatin combination to standard congestive heart failure (CHF) treatment versus addition of atorvastatin alone on CHF outcomes. METHODS: This study was a double-blind, randomized placebo-controlled trial. In the present study, 62 eligible patients were enrolled and randomized into 2 groups. In the intervention group patients received 10 mg atorvastatin daily plus 100 mg CoQ10 pearl supplement twice daily, and in the placebo group patients received 10 mg atorvastatin daily and the placebo of CoQ10 pearl for 4 months. For all patients echocardiography was performed and blood sample was obtained for determination of N-terminal B-type natriuretic peptide, total cholesterol, low density lipoprotein, erythrocyte sedimentation rate, and C-reactive protein levels. Echocardiography and laboratory test were repeated after 4 months. The New York Heart Association Function Class (NYHA FC) was also determined for each patient before and after the study period. RESULTS: Data analyses showed that ejection fraction (EF) and NYHA FC changes differ significantly between intervention and placebo group (P = 0.006 and P = 0.002, respectively). Changes in other parameters did not differ significantly between study groups. CONCLUSION: We deduce that combination of atorvastatin and CoQ10, as an adjunctive treatment of CHF, increase EF and improve NYHA FC in comparison with use of atorvastatin alone.   Keywords: Coenzyme Q10, Atorvastatin, Clinical Trial, Congestive Heart Failure
