Background: New-onset atrial fibrillation (NOAF) often complicates acute coronary syndromes (ACSs) with adverse short- and long-term consequences. However, the current risk classification model for estimating NOAF during non-ST-segment elevation myocardial infarction (NSTEMI) remains unclear. Some parameters in the CHA2DS2-VASc score are closely related to the development of atrial fibrilation (AF).
Methods: This retrospective study was conducted among 670 consecutive NSTEMI patients who applied to our cardiovascular center between June 2020 and June 2022 and underwent percutaneous coronary intervention (PCI).
Results: NOAF developed during hospitalization in 55 patients (12.5%). NOAF patients were older and had higher high sensitivity C-reactive protein (hs-CRP), left atrial volume index, Post PCI thrombolysis in myocardial infarction (TIMI) grade
Key words: NSTEMI, Atrial fibrillation, CHA2DS2-VASc
