Unveiling a J-shaped association between the triglyceride-glucose index and in-hospital major adverse cardiovascular events in patients with acute myocardial infarction: a retrospective cohort study of 1,065 patients.

This study demonstrates a significant J-shaped nonlinear association between the triglyceride-glucose index and the risk of in-hospital major adverse cardiovascular events, with an identified inflection point at 9.05.

Notably, patients with a medium triglyceride-glucose level (T2 group) exhibited the highest major adverse cardiovascular events risk, which was significantly greater than that of patients with a low triglyceride-glucose level (T1 group).

This finding challenges the conventional linear perception that a higher triglyceride-glucose index consistently correlates with greater risk.
