Background and aims: Prognosis variations in patients discharged after an acute coronary syndrome (ACS) according to the professionals involved has not been clearly outlined. The aim of our study was to assess the impact on a specific outpatient clinic (SOC).
Methods: We included all consecutive patients admitted for an ACS in a single center. We performed a propensity score matching with all patients discharged from hospital according to whether they were referred to the SOC or not.
Results: From the 1822 patients discharged, 260 couples of well-balanced ACS patients were obtained after propensity score matching. Median follow-up was 43.3 months and cardiovascular mortality rate was 10.4%, all-cause mortality was 13.9% and any MACE 38.2%. Patients attended the SOC had significantly lower rates at all three endpoints. Multivariate analysis results showed how the follow-up in the SOC was associated with significantly lower risk at all endpoints. SOC patients also had significantly lower rate at hospital readmissions and the multivariate analysis identified a negative association between the first cardiovascular readmission and SOC (sHR: 0.26 95%CI 0.18-0.367; p < 0.01). Mean LDLc levels at the time of ACS admission was 99.0 (36.7) mg/dl and no difference was observed in patients referred to SOC vs. non-referred. Patients followed at the SOC achieved significantly lower LDLc and higher percentage of LDLc <70 mg/dl (56.7% vs. 36.7%; p < 0.01). SOC follow-up was associated with 44% higher probability of final LDLc <70 mg/dl.
Conclusions: An SOC for ACS patients was independently associated with higher LDLc control and long-term survival.
