Prehospital statin use and low-density lipoprotein cholesterol levels at admission in acute coronary syndrome patients with history of myocardial infarction or revascularization: Findings from the Improving Care for Cardiovascular Disease in China (CCC) project
2019
Background Lowering low-density lipoprotein cholesterol (LDL-C) by statins is a key strategy for secondary prevention of acute coronary syndrome (ACS). However, few studies have examined prehospital statin use and admission LDL-C levels in ACS patients with history of myocardial infarction (MI) or revascularization. This study aimed to assess use of prehospital statins and LDL-C levels at admission in ACS patients with history of MI or revascularization. Methods Improving Care for Cardiovascular Disease in China project was a nationwide registry, with 192 participating hospitals reporting details of clinical information of ACS patients from November 2014. By May 2018, 80,282 patients with ACS were included. LDL-C levels were obtained from the initial admission lipid testing. Results Of the 80,282 ACS patients, 6,523 with a history of MI or revascularization were enrolled. Among them, 50.8% were receiving lipid-lowering therapy before hospitalization (statin monotherapy in 98.4%, combination in 1.2%). A total of 30.1% of patients had LDL-C P Conclusions Among ACS patients with history of MI or revascularization, half were not being treated with statin therapy prior to admission, and most had not attained LDL-C
