The aim of the present study was to investigate the association of neutrophil/lymphocyte ratio (NLR) with coronary artery calcium score (CACS) and obstructive coronary artery disease (CAD) detected by multislice computed tomography (MSCT) angiography in type 2 diabetes mellitus (T2DM) patients.
Two hundred and ninety-two T2DM patients, who were either asymptomatic or symptomatic (but noncharacteristic) for coronary artery disease (CAD) and underwent MSCT angiography in our clinic between May 2009 and June 2014, were enrolled. All patients were divided into two groups according to their mean NLR values. Patients with NLR ≤2.05 were assigned to Group 1 and patients with NLR >2.05 were assigned to Group 2. The association of NLR with CACS and obstructive CAD, which were detected by MSCT angiography, was investigated in T2DM patients.
According to the Agatston scoring method, the mean CACS was 129.5±209.8 Au in Group 1 and 290.3±399.6 Au in Group 2 (P<0.001). Obstructive CAD was detected in 40 (26.8%) patients in Group 1 and in 56 (39.2%) patients in Group 2 (P<0.05, P<0.021).
The rate of obstructive CAD was significantly higher in the T2DM patients with NLR >2.05 than that in the T2DM patients with NLR ≤2.05. In addition, the CACS was also significantly higher in the T2DM patients with NLR >2.05 than that in the T2DM patients with NLR ≤2.05.
本研究旨在探讨2型糖尿病(T2DM)患者中性粒细胞/淋巴细胞比值(NLR)与多层螺旋计算机断层扫描(MSCT)血管造影检测的冠状动脉钙化积分(CACS)及阻塞性冠状动脉疾病(CAD)之间的关联。
纳入292例T2DM患者,这些患者无症状或有冠状动脉疾病(CAD)的症状(但不典型),于2009年5月至2014年6月在我院接受MSCT血管造影检查。所有患者根据其平均NLR值分为两组。NLR≤2.05的患者被分配到第1组,NLR>2.05的患者被分配到第2组。在T2DM患者中研究NLR与MSCT血管造影检测的CACS及阻塞性CAD之间的关联。
根据阿加斯顿评分法,第1组的平均CACS为129.5±209.8 Au,第2组为290.3±399.6 Au(P<0.001)。第1组有40例(26.8%)患者检测到阻塞性CAD,第2组有56例(39.2%)患者检测到阻塞性CAD(P<0.05,P<0.021)。
NLR>2.05的T2DM患者阻塞性CAD的发生率显著高于NLR≤2.05的T2DM患者。此外,NLR>2.05的T2DM患者的CACS也显著高于NLR≤2.05的T2DM患者。
