Abstract: Background Repeat hospitalizations for recurrent acute coronary syndrome (ACS) or unplanned revascularization after acute myocardial infarction (MI) are common, costly and potentially preventable. We aim to describe 10-year trends and identify independent risk factors of these repeat hospitalizations. Methods We analyzed data from 9615 patients from the Melbourne Interventional Group registry (2005–2014) who underwent percutaneous coronary intervention (PCI) for their index MI and survived to discharge. Patients with ≥1 hospitalization for recurrent ACS events and/or unplanned revascularization in the year after discharge were included in the recurrent coronary hospitalization group. We assessed yearly trends of recurrent coronary events and identified independent predictors using multivariate analysis. Results Recurrent coronary hospitalization occurred in 1175 (12.2%) patients. There was a significant decrease in the rate of recurrent ACS hospitalization (15.3%-7.6%, P for trend <.001) and unplanned revascularization (4.2%-2.1%, P for trend = .01), but not in all-cause re-hospitalizations (P for trend = .28). On multivariate analysis, female gender, diabetes mellitus, previous coronary bypass surgery, previous PCI, reduced ejection fraction, heart failure, multi-vessel coronary disease and obstructive sleep apnea were independent predictors of recurrent coronary hospitalizations (all P < .05). Conclusions Recurrent hospitalization for ACS or unplanned revascularization has decreased significantly over the past decade. Risk factors for such events are numerous and largely non-modifiable, however they identify a cohort of patients in whom non-culprit vessel PCI in multi-vessel disease, optimization of left ventricular dysfunction and diabetes management may improve outcomes.
