Lemor A, et al. - In non-ST-elevation acute coronary syndrome (NSTE-ACS) researchers investigated the predictive factors and etiologies of 30-day readmissions. The participants included patients with a primary diagnosis of NSTE-ACS identified using ICD9 code in the National Readmission Database 2014. This study included overall 300,269 patients. A total of 13.4% of patients sought readmission within 30 days. According to the findings, a high readmission rate at 30 days was noted among NSTE-ACS patients. Heart failure (HF) and recurrent myocardial infarction (MI) were found to be responsible for the majority of the readmissions. The most significant predictors for readmission were a Charlson Comorbidity Index (CCI) more than 3 and ESRD. Lower odds of readmission were reported in those undergoing PCI.
