JCEM:血浆同型半胱氨酸与心血管器官损害

2020-05-27 MedSci原创 MedSci原创

这项研究表明Hcy和LV质量之间以及LVH和CVE病史之间存在独立的关联,并提示LVH可能是Hcy和CV风险之间的病理生理联系之一。

尚不清楚血浆同型半胱氨酸(Hcy)是否对心血管(CV)系统具有直接有害影响,或者其与心血管事件(CVE)的关联是否由确定的危险因素所介导。近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,为了探索Hcy在CV损伤中的作用,该研究评估了血浆Hcy与CV器官损伤指标之间的横断面关系,以及这些指标与CVE病史之间的关联。

研究人员对269例糖尿病、血脂异常和高血压患者测量了颈动脉内膜中层厚度、踝臂指数(ABI)、反应性充血指数、颈股股脉搏波速度(cfPWV)、左心室(LV)质量和心脏指数。

132名患者有颈动脉斑块,31名患者ABI<0.90,126名患者内皮功能障碍,66名患者cfPWV增加,125名患者LV肥大(LVH),153名患者心脏指数降低和115名患者有CVE病史。校正协变量和肌酐后,血浆Hcy水平与LV质量和ABI有关。与LV质量和ABI在极限范围内的患者相比,LVH(8.5[4.4] vs 7.6[2.8]μmol/L;校正后的P=0.001)和ABI<0.9(10.4[3.8] vs 7.9[3.4]μmol/L;校正后的P=0.001)患者Hcy水平显著升高。在伴有和不伴有颈动脉斑块、动脉僵硬度增加、内皮和LV泵功能受损的患者中,Hcy水平相当。在CV器官损伤的标志物中,只有LVH与CVE病史相关。

由此可见,这项研究表明Hcy和LV质量之间以及LVH和CVE病史之间存在独立的关联,并提示LVH可能是Hcy和CV风险之间的病理生理联系之一。
