If you have heart disease, you might wonder what else could put your heart at risk. A new study looked at 3,872 patients with coronary artery disease to see if certain obesity-metabolic indices—like triglyceride glucose (TyG) and a score called METS-IR—could signal heart failure risk.
The study found all four indices were linked to heart failure, and the connection got stronger when the numbers crossed certain thresholds. METS-IR was the best at identifying people who already had heart failure. The research also suggested these measures might affect heart failure partly through kidney function.
This was an observational study, so it can't prove these indices cause heart failure—only that they're associated with it. The study was retrospective, meaning it looked back at past data, which limits how certain we can be. No safety issues were reported, but the findings need more validation before changing care.
For now, these indices might help doctors spot higher-risk patients with heart disease, but they shouldn't be used alone to guide treatment.
