应用二维超声心动图,采用双平面面积长度法,测定65例高血压病患者及40例正常人的左房最大容积(MAXV)、左房容积指数(MAXVI)。结果显示,高血压病患者MAXV和MAXVI较正常人显著增大(P<0.001)。对导致高血压病患者左房容积改变的可能因素进行研究分析,发现高血压病患者左房容积增大与左室重量指数(LVMI)、年龄、体循环舒张压有关。
The left atrium volume (MAXVI) and left atrium volume index (MAXVI) were measured in 65 hypertensive patients and 40 normal subjects by using two-dimensional echocardiography and bi-plane area length method. The results showed that the MAXV and MAXVI in hypertensive patients were significantly higher than those in normal controls (P <0.001). To study the possible causes of the change of left atrium volume in hypertensive patients, we found that the increase of left atrium volume in patients with hypertension is related to left ventricular mass index (LVMI), age and systolic diastolic pressure.
