Abstract
Background: Although mortality after acute coronary syndrome (ACS) has improved in the acute phase, cardiovascular events occur at a certain frequency in the chronic phase. A hospital lipid-lowering protocol (HLP) could be effective in providing optimal lipid-lowering therapy to improve long-term clinical outcomes after ACS.
Aims: This study investigated the impact of HLP on clinical outcomes in patients with ACS.
Methods: We retrospectively analysed 1,114 ACS patients who had undergone successful percutaneous coronary intervention between November 2011 and June 2021. In December 2018, we introduced a HLP that included the prescription of the maximum tolerated dose of statin, ezetimibe, and eicosapentaenoic acid after ACS treatment. We compared 2-year clinical outcomes before (control group: 791 patients) and after the HLP's introduction (HLP group: 323 patients). The primary outcome was the non-target vessel revascularisation (non-TVR) rate. A multivariate Cox proportional hazard model and inverse probability weighting (IPW) based on the propensity score were used to evaluate the effect of HLP on the outcomes.
Results: The cumulative 2-year non-TVR incidence was significantly lower in the HLP group than in the control group (8.5% vs 13.8%; p=0.019). Multivariable analysis revealed non-TVR risk was significantly lower in the HLP group than in the control group (adjusted hazard ratio [aHR]: 0.637 [95% confidence interval [CI]: 0.416-0.975]; p=0.038). The IPW analysis confirmed a significant association between the HLP and a lower non-TVR risk (aHR: 0.544 [95% CI: 0.350-0.847]; p=0.007).
Conclusions: Implementing HLP for ACS patients improved the 2-year clinical outcome.
