Abstract

Background: High-density lipoprotein (HDL) particles exert many beneficial actions that may help protect against cardiovascular disease. However, recent work has demonstrated that HDL can be oxidized and glycated under certain circumstances and may become pro-atherogenic. The present study investigated the impact of oxidized high-density lipoprotein (ox-HDL) and glycated apolipoprotein A-I (gly-ApoA-I) in patients presenting with ST-elevation myocardial infarction (STEMI).

Methods: We assessed 55 consecutive patients with STEMI. Patients were divided into: (1) a stress hyperglycaemia (SH) and a no SH group; and (2) a high thrombus burden (HTB) group and a low thrombus burden (LTB) group. Meanwhile, 48 healthy volunteers were recruited as controls. Plasma ox-HDL and gly-ApoA-I concentrations were measured on admission and 7 days after admission.

Results: Higher concentrations of ox-HDL and gly-ApoA-I were found in the STEMI group than in the control group on admission and at d7. Further subgroup analysis showed that ox-HDL and gly-ApoA-I were higher in the SH group than in the no SH group at both time points; the HTB group had higher ox-HDL and ox-HDL/HDL-C levels than the LTB group on admission and at d7. However, gly-ApoA-I and the relative intensity of ApoA-I glycation showed no significant differences between the HTB and LTB groups.

Conclusions: The present data indicate that: (1) SH is associated with increased plasma concentrations of ox-HDL and gly-ApoA-I and therefore aggressive treatment is recommended; and (2) that ox-HDL and ox-HDL/HDL-C were higher in the HTB group and may be used to quantify thrombus burden.
