Current literature lacks a comprehensive analysis of phenotypic heterogeneity within NAFLD-T2DM-CVD clusters and fails to address sex-specific and ethnic variations in disease progression patterns adequately. A systematic literature search was conducted across PubMed, Medline, Embase, Web of Science, and Google Scholar databases from inception to June 2024, employing various combinations of terms including NAFLD, NASH, T2DM, and CVDs, with emphasis on identifying mechanistic pathways, epidemiological trends, and therapeutic innovations. This review identifies novel pathophysiological mechanisms linking hepatic steatosis, insulin resistance, and cardiovascular dysfunction, including previously underexplored roles of gut microbiome dysbiosis, advanced glycation end products, and epigenetic modifications. Emerging evidence suggests distinct molecular signatures that could facilitate precision medicine approaches. The intricate interplay between diabetes, hepatic dysfunction, and cardiovascular complications represents a global health challenge requiring integrated management strategies.
