Abstract: Non-alcoholic fatty liver disease (NAFLD) is currently the most prevalent cause of chronic liver disease globally, affecting approximately 30% of adults worldwide. NAFLD leads to a significant number of adverse effects related to hepatic and extrahepatic diseases, burdening healthcare systems with significant utilization of medical resources. Cardiovascular disease (CVD) is the main cause of mortality in patients with NAFLD. In recent years, the incidence rate of heart failure (HF) has become the fastest growing cardiovascular disease in the world. Multiple studies have shown that non-alcoholic fatty liver disease is closely related to the occurrence and development of heart failure. This article aims to explore the correlation, possible mechanisms and treatment options between non-alcoholic fatty liver disease and heart failure, in order to gain a deeper understanding of the correlation between non-alcoholic liver disease and heart failure and to provide reference for better research on therapy options.
