Why the study?
The predictive value of the HAVOC score, originally developed for cryptogenic stroke or transient ischemic attack, had not been evaluated for new-onset AF in patients with STEMI.
Does the HAVOC score predict new-onset atrial fibrillation in patients with ST elevation myocardial infarction?
Population
1640 patients with STEMI undergoing primary PCI
Comparison
Patients with vs without new-onset AF
Design
Retrospective cohort study
Key result
A high HAVOC score was an independent predictor of new-onset atrial fibrillation in patients with STEMI (OR 1.078; 95% CI 1.022-1.258; p=0.001).

May support HAVOC for NOAF risk stratification in STEMI; hypothesis-generating and requires prospective validation before clinical adoption.

Does the HAVOC score predict new-onset atrial fibrillation in patients with ST elevation myocardial infarction?
Odds Ratio: 1.078 (95% CI 1.022–1.258)
p-value: p=0.001
The HAVOC score is an independent predictor of new-onset atrial fibrillation in patients presenting with STEMI.
Bayam et al. (2026) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=1,640). HAVOC score was evaluated on New-onset atrial fibrillation (NOAF) (OR 1.078, 95% CI 1.022-1.258, p=0.001). A high HAVOC score was an independent predictor of new-onset atrial fibrillation in patients with STEMI (OR 1.078; 95% CI 1.022-1.258; p=0.001).
