Cholesterol subfraction analysis in patients with acute coronary syndrome
Abstract
There is a close relationship between lipid metabolism disorders and atherosclerosis. Guidelines focus on lowering low density lipoprotein cholesterol (LDL-C) levels. However, it should be kept in mind that LDL and high density lipoprotein (HDL) consist of subfractions which can affect the progression of atherosclerosis. We assessed the concentration of LDL and HDL subfractions in patients with acute coronary syndromes (ACS). The influence of the presence of type 2 diabetes mellitus on LDL and HDL subfractions was also analysed. The study group consisted of 127 patients (62 men, 65 women) with ACS. All patients had coronary angiography and coronary angioplasty and stenting when necessary. Medical history was collected during 12 months of follow-up. HDL and LDL subfraction distribution was measured using Lipoprint (Quantimetrix). No differences in LDL nor HDL subfractions were observed between ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina (UA) patients. However, those with restenosis and the necessity of repeated revascularization had higher levels of intermediate-density lipoprotein C (IDL-C) (p=0.055) and LDL3 (p=0.048) compared with patients wit...Continue Reading
