Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as a public health threat as it affects approximately 38% of the adult population worldwide, with its prevalence rising in step with that of obesity and type 2 diabetes. Beyond the implications of MASLD for liver health, it is also associated with cardiovascular and vascular dysfunction. Although the many shared risk factors and common metabolic milieu might indicate that cardiovascular disease and MASLD are discrete outcomes from common systemic pathogeneses, a growing body of evidence has identified a potential causal relationship between MASLD and coronary artery disease, which is the leading cause of morbidity and mortality in people with MASLD and all-cause mortality worldwide. This Review takes an interdisciplinary approach, drawing on hepatology, cardiology, endocrinology, and metabolic and internal medicine specialists to help to delineate the intricate interplay between MASLD and coronary artery disease. It sheds light on novel opportunities for targeted interventions and personalised management strategies.
