摘要 目的探讨老年脑血管病患者血浆溶血磷脂酸(LPA)水平的变化。方法采用紫外比色法检测血浆LPA含量。结果TIA组、脑梗死组、脑出血组及对照组初查时血浆LPA浓度分别为3.96±1.44umol/L、2.75±1.05umol/L、1.87±0.82umol/L、1.82±0.81umol/L。TIA组、脑梗死组两组间LPA结果差异显著(P<0.01),且均高于脑出血组及对照组(P<0.01)脑出血组及对照组之间LPA浓度差异无显著性意义(P>0.05)。TIA组、脑梗死组经临床抗凝抗血小板治疗2周后,LPA浓度明显降低(P<0.001)。而脑出血组,复查时LPA浓度水平却无明显改变(P>0.05)。结论血浆中LPA为体内凝血和血栓形成过程中早期释放的分子标记物,其浓度测定可作为短暂性脑缺血、脑死诊断的重要指标。在预测脑血管病的发生,转归及指导合理应用抗血小板及抗凝药物方面有重要的临床应用价值。
