This review examines the complex interactions of the cardiohepatic axis, with a particular focus on how liver disease impacts heart function. We highlight the roles of portal hypertension, systemic inflammation, hemodynamic changes, and neurohormonal signaling to shed light on this important connection. The underlying mechanisms for impaired cardiac performance involve both molecular and structural changes. Diagnosis remains challenging because it is frequently subclinical; however, advanced imaging, biomarkers, and electrocardiographic changes have improved early detection. Clinically, this syndrome has significant implications, particularly in decompensated cirrhosis and periods of increased myocardial stress. Although no standardized treatment guidelines exist, orthotopic liver transplantation remains the most effective intervention and often results in cardiovascular recovery. A multidisciplinary approach between cardiologists, hepatologists, and transplant surgeons is crucial to improving patient outcomes and optimizing long-term management.</div></div>","PeriodicalId":14831,"journal":{"name":"JACC: Basic to Translational Science","volume":"10 7","pages":"Article 101314"},"PeriodicalIF":8.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144721930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we discuss the emerging evidence of organ crosstalk during cardiometabolic disease with an emphasis on the liver-to-heart axis. We highlight potential mechanisms by which metabolic dysfunction-associated steatotic liver disease contributes to cardiovascular complications. Metabolic dysfunction-associated steatotic liver disease, particularly its inflammatory entity, leads to the production of liver-derived secretory factors that regulate cardiac metabolism, inflammation, and remodeling. Thus, secreted hepatic factors represent an important mechanism of communication between the liver and heart during cardiometabolic disease. In addition to the direct crosstalk between organs, we argue that bone marrow reprogramming and clonal hematopoiesis of indeterminate potential are shared mechanisms of systemic inflammation that regulate the heart–liver axis during cardiometabolic disease. Thus, integrated cardiometabolic strategies hold a significant potential to bridge the gap between liver and cardiovascular health to improve patient outcomes.</div></div>","PeriodicalId":14831,"journal":{"name":"JACC: Basic to Translational Science","volume":"10 7","pages":"Article 101309"},"PeriodicalIF":8.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144721928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
