Abstract:

ObjectiveTo explore the correlation of circulating lipoproteinassociated phospholipase A2 (LpPLA2) and hemoglobin A1c (HbA1c) levels with the severity of coronary artery stenosis in patients with type 2 diabetes mellitus (T2DM). MethodsA total of 241 inpatients with suspected coronary artery disease (CHD) admitted in our department between July, 2017 and December, 2017 were enrolled in this study. According to the findings in coronary angiography, the patients were divided into CHD, T2DM, CHD with T2DM and healthy control groups. The patients were also stratified according to their left ventricular ejection fraction (LVEF) into LVEF <50% group and LVEF≥50% group. For all the participants, circulating HbA1c level was determined with chemiluminescence detection and LpPLA2 level with enzymelinked immunosorbent assay (ELISA). ResultsLpPLA2 level was significantly higher in diabetic patients with CHD than in those with T2DM and the healthy control subjects (P<0.05). The diabetic patients with CHD also showed a significantly higher level of HbA1c than those with CHD and the control subjects (P<0.05). Multivariate linear regression analysis showed that LpPLA2 (r=0.189, P<0.05) and HbA1c (r=0.138, P<0.05) levels were both positively correlated with the severity of coronary stenosis (Gensini score). Multivariate logistic regression analysis identified LpPLA2 (OR=1.012, P<0.05) and HbA1c (OR=0.097, P<0.05) as independent risk factors for coronary stenosis. The patients with a LVEF <50% had a significantly higher LpPLA2 level than those with a LVEF ≥50% (P<0.05), but their HbA1c level did not differ significantly (P>0.05). ConclusionIn diabetic patients with CHD, LpPLA2 and HbA1c levels are positively correlated with the severity of coronary artery stenosis, and the combined detection of LpPLA2 and HbA1c can be clinically informative for predicting the severity of coronary artery stenosis.
