NASH-FITTER: Nonalcoholic Steatohepatitis Fitness Intervention Treatment Targeting Endothelial Dysfunction Reversal

Preliminary studies show universally low cardiorespiratory fitness (CRF) in Nonalcoholic steatohepatitis (NASH) patients was dependent on body composition. The proposed work is based on the hypothesis that gains in cardiorespiratory fitness and improved endothelial function achieved through exercise can arrest or reverse progression of hepatic fibrosis, lessen cardiovascular disease risk (CVD), and improve all-cause mortality in patients with NASH. The aims of this research proposal are designed to characterize and better understand the effects of physical activity (PA) on CRF and endothelial function in patients with NASH. The goal is to arrest progression of fibrosis and reduce CVD risk. This proposal includes a cross-sectional study and a small pilot clinical trial in a high-risk subgroup of NASH most likely to benefit from PA.
