AIMS: To evaluate the incidence and causes of rehospitalization within 1-year after percutaneous coronary intervention (PCI) in a country where the National Health Service provides universal tax-supported health care, guaranteeing residents free hospital access.

METHODS AND RESULTS: Between January 2010 and September 2014, 17,111 patients were treated with PCI in two University Hospitals in Western Denmark. Patients who were readmitted within 1-year after PCI were identified. Overall 1-year readmission rate was 50.4%. The cause was angina/myocardial infarction (MI) in 4,282 patients (49.7%), and other reasons in 4,334 (50.3%). Predictors for angina/MI-related readmissions were female gender (odds ratio (OR) 1.15;95% confidence interval (CI) 1.07-1.25), diabetes (OR 1.14;95% CI 1.04-1.26), age (per 10-year increase) (OR 0.86;95% CI 0.83-0.88), and indication for index PCI (stable angina pectoris as reference): ST-segment elevation myocardial infarction (OR 1.34;95% CI 1.23-1.47) and non-ST-segment elevation myocardial infarction (OR 1.18;95% CI 1.08-1.29). Predictors for other readmissions were female gender (OR 1.09;95% CI 1.01-1.18), diabetes (OR 1.29;95% CI 1.18-1.42), age (OR 1.30;95% CI 1.26-1.34) and Charlson Comorbidity Index ≥ 3 (OR 3.03;95% CI 2.71-3.27) Conclusions: In an unselected patient cohort treated with PCI, half of the patients were rehospitalized within 1-year, illuminating the impact of comorbidity in patients with ischemic heart disease.
