Intensive early and sustained lowering of non–high-density lipoprotein cholesterol after myocardial infarction and prognosis: the SWEDEHEART registry

Summary

BACKGROUND AND AIMS: Non-HDL-C provides an estimate of lipid-associated risk and is a secondary treatment target after myocardial infarction (MI). The aim was to study the relationship between non-HDL-C levels after MI and risk of adverse outcomes. METHODS: From the SWEDEHEART registry, 56 262 patients with MI were included. Outcomes were major adverse cardiovascular event (MACE: death, MI, and ischaemic stroke), death, and non-fatal MI. Non-HDL-C was assessed at admission, 2 months, and 1 year. Target achievement (<2.2 mmol/L) of non-HDL-C, timing thereof, and outcomes were assessed. RESULTS: During median follow-up of 5.4 years, 9549 had MACE, 5427 died, and 3946 had MI. Long-term hazard ratio (HR) for MACE in the lowest vs. the highest quartile of achieved non-HDL-C at 1 year was 0.76 [
