The C-reactive protein-triglyceride-glucose index predicts new-onset atrial fibrillation after ST-segment elevation myocardial infarction

Key Points

New-onset atrial fibrillation (NOAF) is predicted by the C-reactive protein-triglyceride-glucose index (CTI) after myocardial infarction.
CTI shows superior predictive value over hs-CRP and TyG index alone, facilitating improved patient care.

Structured PICO

Does the C-reactive protein-triglyceride-glucose index (CTI) predict new-onset atrial fibrillation in STEMI patients undergoing primary PCI better than hs-CRP or TyG index alone?

Population

STEMI patients undergoing primary PCI

Intervention

C-reactive protein-triglyceride-glucose index (CTI)

Comparator

hs-CRP or TyG index alone

Outcome

New-onset atrial fibrillation (NOAF)hard clinical

The C-reactive protein-triglyceride-glucose index (CTI) is a superior predictor for new-onset atrial fibrillation after primary PCI in STEMI patients compared to its individual components.

Abstract

CTI is an independent risk factor for post-primary PCI NOAF in STEMI patients. It exhibits superior predictive value for NOAF compared to hs-CRP or TyG index alone, making it a clinically useful tool for risk stratification in this patient population.
