Core Tip

Core Tip: Metabolic dysfunction-associated fatty liver disease (MAFLD) and type 2 diabetes mellitus (T2DM) are independent risk factors for the development of cardiovascular disease (CVD) with an exaggerated risk of cardiovascular events (CVE) when both diseases co-exist. A systematic review of fourteen studies with 370013 participants showed that the risk of CVE in T2DM was higher in the MAFLD group when compared to the non-MAFLD group [odds ratios (OR): 1.28] with follow up duration ranging between 5-6 years. The prevalence of CVD was higher (OR: 1.47) in T2DM with MAFLD when compared to T2DM without MAFLD. In conclusion, presence of MAFLD in T2DM increased the risk of CVE and CVD as compared to T2DM without MAFLD.
