冠心病合并糖尿病患者冠状动脉介入术前后血栓形成前状态分子标志物的变化

目的　观察冠心病 (CAD)合并糖尿病 (DM)患者冠状动脉介入术前后血栓形成前状态(PTS)分子标志物变化情况。方法　选择 32例CAD(A组 )及 2 4例CAD合并非胰岛素依赖性糖尿病(NIDDM ,B组 )患者行冠状动脉介入术 ,分别在术前、术后 2 0min、2 4h、7d采血测定PTS分子标志物、脂质过氧化物 (LPO)及血管内皮功能指标。结果　术后两组患者PTS分子标志物、LPO及内皮功能均较术前有明显变化 ,且B组变化更明显 ,至术后第 7d ,A组基本恢复至术前水平 ,但B组仍有明显变化。结论　CAD患者介入术后出现PTS分子标志物、脂质过氧化损伤以及内皮功能等一系列变化 ,并且这种变化在合并DM的患者更为明显。

The changes and significance of molecular markers of prethrombotic state in coronary artery patients with diabetes mellitus undergoing coronary angioplasty

Objective To observe the changes of molecular markers of prethrombotic state (PTS) in coronary artery disease (CAD) patients with diabetes mellitus (DM) undergoing coronary agioplasty. Methods Thirty-two patients with CAD (group A) and twenty-four CAD patients with noninsulin-dependent diabetes mellitus (NIDDM) (group B) were chosen as objects undergoing coronary agioplasty, and molecular markers of PTS, lipid peroxide (LPO), endothelial function were measured before and 20 minutes, 24 hours, and 7 days after the opration respectively. Results There were significant changes of molecular markers of PTS, LPO, and endothelial function in both groups after the opration, but the changes were even more pronounced in group B. It was on the 7th day that there were still the changes in group B, whereas the changes were prone to the levels of pre-opration in group A. Conclusion There was a series of significant changes of molecular markers of PTS, LPO, and endothelial function in CAD patients after the angioplasty, and the changes were even more pronounced in those with DM.
