摘　　要：本文采用M型超声心动图对112例原发性高血压患者和104例正常对照者作了观察。超声测量值经年龄和体表面积校正后,患者中73%示左室后壁或室间隔厚度增加,12%呈非对称性室间隔肥厚;58%呈左室心肌重量指数异常增加,反映左室收缩功能的喷血分数和平均周径纤维缩短率及反映左室舒张功能的二尖瓣EF速度和舒张早期径纤维伸长速度也显著低于正常对照。多因素逐步回归分析显示原发性高血压患者的左室心肌重量和形态改变是影响左室收缩功能的主要因素。结果提示:超声心动图对左室肥厚的估计较心电图或X线优越,使早期检出率大大提高,并可通过对左室收缩和舒张功能的定量测定提高临床对高血压性心脏损伤的估计能力。M-mode ultrasound scan was applied to investigate the structural and iunctionat changes of the heart in 112 cases of essential hypertension,with 104 age and sex matched normotensives as control group.After correcting the age and body surface area,the abnormal increase in thickness of posterior left ventricular wall and of the ventricular septum was found in 73%of the patients,and an increase in left ventricular myocardial mass in 58%.Systolic and diastolic functional indices—ejection fraction,mean eireumferen tial fiber shortening rate,mitral valve early diastolic closure rate and early diastolic circumferential fiber lengthening rate—all decreased significantly in hypertensive group,Multiple continued regressional analysis showed that the left ventricular myocardial mass which reflected the degree of left ventrieular hypertrophy was the important factor influencing the systolic function in essential hypertension.The results suggest that the echocardiographic exam may be helpful in early detection and quantitative estimation of the cardiac abnormalities in essential hypertension.
