摘要
目的了解高血压前期人群的左心室结构和功能特点。方法依据美国预防、检测、评估与治疗高血压联合委员会第7次报告对高血压进行的重新分类,按血压水平分为:血压正常组(normotension,NTN 组)75例,高血压前期组(pre—hypertension,PHT组)124例,高血压组(hypertension,HTN组)195例,应用超声心动图检测他们的左心室结构和功能。结果 HTN组与NTN组和PHT组舒张末期室间隔厚度、舒张末期左心室后壁厚度、左心室壁相对厚度、左心室质量及左心室质量指数的差异有统计学意义,其中HTN组与NTN组之间的差异有统计学意义(P<0.01),而PHT组与NTN组的差异无统计学意义;左心室功能随血压水平的升高而减退,但3组之间舒张功能的差异无统计学意义(P>0.05),而收缩功能的差异有统计学意义(P<0.05),其中HTN组与NTN组之间的差异有统计学意义(P<0.01)。结论高血压前期人群可出现心脏结构和功能的改变,随血压水平的升高,其收缩功能的损害更为突出,左心室结构的改变更为明显。
