Sykes RA, Mohamed MO, Kwok CS, et al. - Most, but not all, patients exhibit improvement in anginal chest pain after undergoing percutaneous coronary intervention (PCI). Correlation has been observed between PCI and unplanned readmission for angina and non‐specific chest pain within 30‐days of index PCI. From the United States Nationwide Readmissions Database, researchers assessed 2,723,455 patients with an index hospitalization for PCI. The 30‐day unplanned readmission rate was 7.2% (n = 196,581, 42.3% female), which included 9.8% (n = 19,183) with angina and 11.1% (n = 21,714) with non‐specific chest pain. Patients in the unplanned readmission group were relatively younger (62.2 vs 65.1 years), more frequently females (41.0% vs 34.2%), from the lowest quartile of household income, have higher prevalence of cardiovascular risk factors or have index PCI performed for non‐acute coronary syndromes (ACS). Following factors were noted to be linked with angina readmissions: female gender, history of ischemic heart disease (IHD), coronary artery bypass grafts, anemia, hypertension, and dyslipidemia. Relative to those with angina readmissions, those with non‐specific chest pain were younger, more likely to be females and have undergone PCI for non‐ACS. Likelihood of readmission with angina or non‐specific chest pain at 30‐days was greater in correlation with indications for PCI other than ACS. Patients with modifiable risk factors, previous history of IHD and anaemia, were more commonly readmitted.
