白大衣高血压对心脏结构和功能的影响

Influence of White Coat Hypertension on Cardiac Structure and Function

目的 了解白大衣高血压对左心结构和功能的影响。方法 通过诊室血压测量和 2 4h动态血压监测将患者分为白大衣高血压组和持续性高血压组 ,采用超声心动图测量比较每组患者的心脏结构、功能。结果 白大衣高血压组左房内径、左室后壁厚度和左室质量指数均低于持续高血压组 ,但高于正常对照组 (P <0 .0 5 ) ,舒张功能较对照组下降。结论 白大衣高血压可能造成心脏损害 ,但是危险性低于持续高血压。

Objective To assess the structure and function of heart in patients with white coat hypertension (WCH). Methods WCH and sustained hypertension (SH) were classified by clinical and 24 hours ambulatory blood pressure. The structure and function of heart were measured by echocardiography. Results The LAD,IVPW and LVMI in WCH patients were larger than those in normal group but less than those in SH. The diastolic function was decreased in WCH group compared with normal groups. Conclusion There were changes of left ventricular diastolic function and remodeling of left ventricle in WCH patients,and the risk of WCH was lower than SH.
