摘要 心血管疾病是严重危害人类健康的疾病之一,冠状动脉粥样硬化性心脏病、高血压、心肌肥厚、心力衰竭等疾病的发病率呈逐年上升趋势,临床上,正确地对心血管疾病进行风险分层具有重大意义。相较于正常左心室质量的人群而言,并非所有的左心室肥厚均会增加患者心血管不良事件(心肌梗死、卒中、室性心律失常、心力衰竭、心源性死亡等)的发生率。不适宜的左心室质量(i LVM),是指某一个体的左心室质量超过个人血流动力学负荷所能代偿部分的一种状态。i LVM不仅与左心室构型异常及心脏收缩及舒张功能障碍密切相关,而且预示了较高的心血管疾病风险。评估i LVM能够提高对患者潜在心血管疾病的识别能力并及时提示医生采取干预措施,有利于减缓及逆转左心室肥厚的发展,一定程度上减少不良心血管事件的发生,对于降低患者的心血管疾病的发病率和病死率,改善长期预后具有重要的临床意义。现就i LVM的研究进展进行综述。
