To investigate the predictive capacity of a systemic immune-inflammation index (SII) in detecting new-onset atrial fibrillation (NOAF) following ST segment elevation myocardial infarction (STEMI). A total of 402 STEMI patients were enrolled in the study. The patients were divided into two groups according to NOAF development. A cut-off point of 1,228,000 for SII was identified with 60% sensitivity and 78.1% specificity to predict NOAF following STEMI. According to pairwise analysis of receiver operating characteristic curve analysis, the predictive power of SII in detecting NOAF following STEMI was similar to high-sensitive C-reactive protein, and better than neutrophil-to-lymphocyte ratio or platelet-to-lymphocyte ratio. SII can be used as one of the independent predictors of NOAF following STEMI.

Background: New-onset atrial fibrillation (NOAF) complicating ST-segment elevation myocardial infarction (STEMI) remains clinically challenging. The aim of this study was to assess the incidence of NOAF, identify risk factors for the development of atrial fibrillation (AF), and analyze the impact on patient care, therapy, and outcomes during long-term follow-up.

Methods: This retrospective single-center study reviewed consecutive patients undergoing coronary angiography (CAG) for acute STEMI between May 2015 and September 2023.

Background: New-onset atrial fibrillation (NOAF) is a common adverse outcome in acute ST-segment elevation myocardial infarction (STEMI) patients following percutaneous coronary intervention (PCI) and is associated with a worse prognosis. The platelet-to-albumin ratio (PAR) has been utilized to predict the severity and prognosis of cardiovascular diseases. This study aims to investigate the predictive value of PAR combined with the CHEST score for NOAF in the elderly population with STEMI undergoing PCI.

Aims: Improvement in left ventricular ejection fraction (impEF) often presents in contemporary acute myocardial infarction (AMI) patients. New-onset atrial fibrillation (NOAF) during AMI is an important predictor of subsequential heart failure (HF), while its impact on the trajectory of post-MI left ventricular ejection fraction (LVEF) and prognostic implication in patients with and without impEF remains undetermined. We aimed to investigate the prognostic impacts of NOAF in AMI patients with and without impEF.

Background And Aims: Atrial fibrillation (AF) is a common arrhythmia that occurs following ST-elevation myocardial infarction (STEMI) and can significantly impact clinical outcomes. We investigated the incidence and predictors of AF following STEMI in patients, as well as its association with major adverse cardiac and cerebrovascular events (MACCE).

Methods: We conducted a retrospective cohort study, including all STEMI patients who presented under code 247 to Tehran Heart Center between 2016 and 2020 and completed a 1-year follow-up.

Background: Lipopolysaccharide (LPS) is related to various cardiovascular diseases. However, the relationship between LPS and new-onset atrial fibrillation (NOAF) after ST-segment elevation myocardial infarction (STEMI) has yet to be elucidated. This study aimed to evaluate the impact of LPS on NOAF in STEMI patients.
