Patient follow-up after acute coronary syndrome: the Apulia PONTE-SCA program

Background. Patients who suffered from acute coronary syndrome (ACS) need a tight follow-up in order to optimize therapy and prevent adverse events. The aim of the PONTE-SCA Puglia program was to evaluate the impact of an integrated management of patients between hospital and local territorial outpatient facilities on adherence and outcome of patients discharged after ACS event. Methods. This was a prospective, longitudinal, cohort study which enrolled patients who suffered ACS and/or coronary revascularization in a Hub hospital of ASL Bari. Patients underwent clinical and laboratory evaluation at 30 days, 3 months, 6 months, and 1 year after the index event. The following endpoints were considered: all-cause mortality, ACS recurrence/cardiac ischemia/angina, restenosis/intrastent thrombosis, stroke/transient ischemic attack, heart failure, all-cause bleeding. We evaluated persistence on therapies and the percentage of patients who attained therapeutic goals. Results. A total of 2476 patients (mean age 67.2 +/- 12.0 years, 77.4% male) were enrolled. At 1-year follow-up, 99.5% of patients (p<0.05) were on statin therapy, 16.1% (p<0.01) on ezetimibe, and 9.9% (p<0.01) on proprotein convertase subtilisin/kexin type 9 inhibitors. All-cause mortality was 3.1% at 1-year follow-up, whereas recurrence of ACS/cardiac ischemia/angina and restenosis/stent thrombosis were 3% and 1.3%, respectively. The prevalence of all bleeding complications was 2.2%. Conclusions. The PONTE-SCA Puglia program allowed to implement a dedicated taking in charge of patients after an ACS/coronary revascularization event, to manage a dedicated follow-up route for them, to ameliorate persistence on recommended therapies, and to keep lower the incidence of major adverse cardiovascular events and bleedings.
