高血压病患者的左室功能受损来自二个途径:后负荷增加的直接作用,即血流动力学因素,以及左室肥厚的作用,即结构因素。本文旨在研究高血压病患者左室舒张功能与24h 动态血压及心率之间可能存在的相关关系。由于年龄与左室肥厚均可使左室功能受损,因此本文根据年龄及左室壁厚度进行分组研究。对象与方法 235例轻-中度高血压病患者,行24h动态血压及心率监测及 Doppler 超声心动图检查。轻-中度高血压的定义是:收缩压(SBP)≥140mmHg(18.7kPa.
Left ventricular dysfunction in hypertensive patients comes from two pathways: a direct effect of increased post-load, hemodynamic factors, and the role of left ventricular hypertrophy, structural factors. This article aims to study the possible relationship between left ventricular diastolic function and ambulatory blood pressure and heart rate in patients with essential hypertension. Because of age and left ventricular hypertrophy can make left ventricular function impaired, this article based on age and left ventricular wall thickness group study. Subjects and Methods 235 cases of mild to moderate essential hypertension, 24h ambulatory blood pressure and heart rate monitoring and Doppler echocardiography. Light - moderate hypertension is defined as: systolic blood pressure (SBP) ≥ 140mmHg (18.7kPa.
