Low-density lipoprotein cholesterol target achievement in patients surviving an acute coronary syndrome in Hong Kong and Taiwan - findings from the Dyslipidemia International Study II

Abstract

Background: Individuals are at increased risk for cardiovascular events following an acute coronary syndrome (ACS). Effective management of hyperlipidemia, an associated risk factor, is essential for improving outcomes. We aimed to quantify the extent of hyperlipidemia and its treatment in ACS survivors in Hong Kong and Taiwan.

Methods: The multinational, observational Dyslipidemia International Study (DYSIS) II included patients hospitalized for an ACS. Lipid levels and use of lipid-lowering therapy (LLT) were evaluated at baseline and 4 months post-discharge. The proportions of patients attaining the recommended LDL-C target for individuals at very high cardiovascular risk (<70 mg/dL) was assessed and potential predictors of this outcome evaluated.

Results: In total, 270 patients were enrolled, 125 (46.3%) of which were being treated with LLT prior to hospitalization. Of these, 28.8% had an LDL-C level < 70 mg/dL, compared to only 6.9% of those not being treated. Statin monotherapy was the most commonly employed LLT, with a mean atorvastatin-equivalent dosage of 14 mg/day. By 4-month follow-up, target attainment had risen to 45.1% for patients treated with LLT at baseline, and 43.3% for those who had not been treated. LLT was being used by 88.4% of patients at follow-up, with a mean atorvastatin dosage of 18 mg/day. Use of statins in combination with ezetimibe/other non-statin was scarce. No predictors of LDL-C target attainment were identified.

Conclusions: In patients hospitalized with an ACS, rates of LDL-C target achievement were poor. While LLT was widely employed, statin intensity was low and combination therapy underused, indicating scope for improvement.
