摘要(Abstract)：

目的前期研究发现生长分化因子15(growth-differentiation factor-15,GDF-15)与左室内径变化以及心肌缺血/再灌注损伤密切相关,旨在探讨GDF-15与接受急诊冠状动脉介入治疗的ST段抬高型心肌梗死(STEMI)患者远期左室内径及舒张功能变化的相关性。方法连续入选因STEMI于北京大学第三医院接受急诊冠状动脉介入治疗的患者87例,介入治疗前检测GDF-15水平,并于入院后完善基线超声心动图检查。出院后定期门诊随访和冠心病二级预防。平均随访时间18个月,复查超声心动图,分别计算左心室舒张末内径(LVEDD)和二尖瓣E峰速度与二尖瓣环舒张早期峰值速度比值(E/Em)的变化率。统计分析基线GDF-15与心室重构的相关性。结果患者的平均GDF-15水平为(986.48±322.99)pg/ml。超声心动图检查显示随访患者LVEDD较基线平均增加(2.68±8.82)%,E/Em较基线平均增加了(4.51±33.50)%。GDF-15与LVEDD变化率存在负相关(r=-0.514,P<0.01),与E/Em变化率存在负相关(r=-0.501,P<0.01)。以964.67pg/ml作为界值,GDF-15预测LVEDD改善趋势的敏感性为77.4%,特异性为67.9%;预测E/Em改善趋势的敏感性为76.5%,特异性为69.8%。结论 GDF-15水平可能部分预测早期完全再血管化的STEMI患者远期LVEDD及舒张功能的改善趋势。
