Systemic immune inflammation index predicts new onset atrial fibrillation after ST elevation myocardial infarction.
Aim: 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) Patients methods: A total of 402 STEMI patients were enrolled in the study. The patients were divided into two groups according to NOAF development. Results: 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. Conclusion: SII can be used as one of the independent predictors of NOAF following STEMI.
