The effect of 6-month treatment with coenzyme Q10 on endothelial, vascular and myocardial function in patients with nonalcoholic fatty liver disease
Abstract
Background
Patients with Non-alcoholic fatty liver disease (NAFLD) hold an increased cardiovascular risk and present impaired markers of vascular, endothelial and myocardial function. Coenzyme Q10 (CQ10) is a powerful antioxidant that enhances mitochondrial function.
Patients/methods: 52 patients (52±10 years old) with NAFLD were randomized to 240 mg CQ10 (n=25) or placebo (n=27). We measured at baseline and at six months post-treatment: i) Perfused boundary Region (PBR) of the sublingual arterial microvessels (Microscan, Glycocheck), ii) Carotid femoral pulse wave velocity - PWV (Complior ALAM), iii) Flow-mediated dilation (FMD) of the brachial artery, iv) Global left ventricular longitudinal strain (GLS) by speckle tracking imaging, v) Controlled attenuation parameter (CAP) measurement (FibroScan, Echosens).
