Residual Inflammatory Risk of Heart Failure and Atherosclerotic Cardiovascular Disease (CVD) in Diabetes

  • Secondary analysis of the Look AHEAD randomised trial

Authors' conclusion

Among adults with T2D and overweight/obesity, IL-6 identified residual inflammatory risk of incident HF, particularly among adults with no CVD history. An ILI targeting weight loss reduced IL-6 over 1-year of follow-up.
