Early and late new-onset of atrial fibrillation in acute coronary syndromes: Their differences in mortality and cardiac event.

ABSTRACT:

Background

In a stressful situation like acute coronary syndrome (ACS), the occurrence of the first episode of atrial fibrillation is more frequent. The impact of the timing occurrence of AF new-onset (nAF) in the setting of ACS is still debatable.

Methods

Multicenter retrospective study based on the Acute Coronary Syndrome Portuguese National Registry, including 29 851 patients admitted for ACS between 1/10/2010 and 4/09/2019. The group with early nAF - nAF in the first 48 h of hospitalization; and late nAF - patients with nAF after the first 48 h of in-hospital admission.

Results

New-onset AF was identified in 1067 patients, nonetheless, just 38.1% had late nAF. The group with late nAF presented more cardiovascular comorbidities and worse left ventricular ejection f
