本文对左房增大和左房正常的两组高血压病人进行对比观察,以多普勒超声心动图测定左室舒张功能,表明左房增大的高血压病人左室舒张功能受损,是高血压心脏病的早期表现。对象和方法一、观察对象选原发性高血压病人40例,均按WHO诊断标准(收缩压≥21.3kPa(160mmHg)和/或舒张压≥12.7kPa(95mmHg)]确诊。按超声探查结果分为两组:(1)左房增大组:20例,其中男9例,女11例;年龄29～66岁(平均54.5±8.7岁);高血压Ⅰ期4例,Ⅱ期16例;血压波动在20.52±1.32/13.2±0.92kPa;病程9.1±5.4年。
In this paper, left atrial enlargement and left atrial normal hypertensive patients were compared observed by Doppler echocardiography measured left ventricular diastolic function, suggesting that left atrial hypertrophy in patients with impaired left ventricular diastolic function is high Early manifestation of blood pressure heart disease. Subjects and methods First, the observation object selected 40 cases of patients with essential hypertension, according to WHO diagnostic criteria (systolic blood pressure ≥ 21.3kPa (160mmHg) and / or diastolic blood pressure ≥ 12.7kPa (95mmHg)] confirmed by ultrasound findings (1) left atrial enlargement group: 20 cases, including 9 males and 11 females; aged 29 to 66 years (mean 54.5 ± 8.7 years); stage Ⅰ hypertension in 4 cases, stage Ⅱ in 16 cases; Blood pressure fluctuations in 20.52 ± 1.32 / 13.2 ± 0.92kPa; duration of 9.1 ± 5.4 years.
