Popis: It is unknown if acute coronary syndrome (ACS) patients presenting with advanced Killip class (III/IV) would benefit from early statin therapy. Therefore, we aimed to explore the relationship between statin therapy within the first 24 h of medical contact and in-hospital outcomes in this patient population in a nationwide registry.In the Improving Care for Cardiovascular Disease in China-ACS project, among ACS patients presenting with Killip class III/IV, we performed the following three analyses: (i) the associations between early statin therapy and risks for in-hospital mortality and ischaemic events; (ii) the dose effect of statins on mortality and (iii) the interaction between low-density lipoprotein cholesterol (LDL-C) levels and statins on mortality.Among 104,516 ACS patients, 12,149 presented with advanced Killip class and 89.3% received early statins. Multivariable-adjusted logistic regression models revealed a 69% reduction in mortality in the statin group (adjusted odds ratio [OR] 0.31; 95% confidence interval [CI] 0.25-0.39), parallel with a reduction in ischaemic events (adjusted OR 0.50, 95% CI 0.33-0.74), compared with those not receiving early statins, which was consistent in multiple sensitivity analyses. Additionally, the protective association of early statins on in-hospital mortality was observed even among patients that received a low-to-moderate dose. Finally, the short-term survival benefit of early statins was independent of LDL-C.In a nationwide ACS registry, statin therapy initiated within the first 24 h of medical contact was associated with a reduced risk of in-hospital mortality in ACS patients presenting with advanced Killip class.
