Young adults suffering from Prediabetes and hepatic steatosis at Increased risk of Major Adverse Cardiovascular Events: Study
A recent study found that the risk of cardiometabolic outcomes increased in young adults suffering from Prediabetes and hepatic steatosis as per the results that were published in the journal Cardiovascular Diabetology.
Prediabetes is a stage before the development of diabetes that shows increased glucose levels due to disturbances in carbohydrate metabolism. It is one of the risk factors for diabetes and cardiovascular diseases (CVD). Recent data has shown that the levels of diabetes and hepatic steatosis have increased in young adults globally. This is putting at a risk of various CVDs. It is necessary to identify the high-risk individuals who are at risk of developing CVDs due to diabetes and hepatic steatosis. As there is ambiguity in the association between hepatic steatosis, incident DM, and major adverse cardiovascular events (MACE) in young adults with prediabetes, a study was conducted to determine the impact of prediabetes and/or hepatic steatosis on the risk of incident diabetes and MACE in the young cohort.
A nationwide cohort study was carried out on 896,585 young adults under 40 years old without diabetes or previous history of cardiovascular disease. A fatty liver index of ≥ 60 was used to identify individuals with hepatic steatosis. The primary outcomes of this study were incident diabetes (DM) and composite major adverse cardiovascular events (MACE), including myocardial infarction, stroke, or cardiovascular death.
Findings:
- During a median follow-up of 11.8 years, 27,437 (3.1%) incident DM cases and 6,584 (0.7%) MACE cases were recorded.
- After adjusting for covariates, the study found a significantly higher risk of incident DM and composite MACE in Young adults with prediabetes compared to individuals with normoglycemia.
- the combination of prediabetes and hepatic steatosis also posed the highest risk for incident DM and MACE based on the Stratification of hepatic steatosis after adjusting for relevant covariates.
- For incident DM, the HRs were 3.15 for prediabetes without hepatic steatosis, 2.89 for normoglycemia with hepatic steatosis, and 6.60 for prediabetes with hepatic steatosis.
- For composite MACE, the HRs were 1.05 for prediabetes without hepatic steatosis, 1.39 for normoglycemia with hepatic steatosis, and 1.60 for prediabetes with hepatic steatosis.
Thus, the study concluded that prediabetes was associated with an increased risk of incident DM and composite MACE in young adults. Moreover, the coexistence of prediabetes and hepatic steatosis was associated with an increased risk of incident DM and composite MACE when compared to normoglycemic individuals. The researchers suggested early screening for such conditions in young adults with prediabetes. Targeted therapies with lifestyle interventions help provide positive outcomes.
