Binswanger病及Alzheimer病局部脑血流量变化的研究

LEFT VENTRICULAR REMODELING IN 4 WEEKS AFTER ACUTE MYOCARDIAL INFARCTION

测定了Ｂｉｎｓｗａｎｇｅｒ病（ＢＤ）２７例、Ａｌｚｈｅｉｍｅｒ病（ＡＤ）２１例和健康对照组２７名的局部大脑血流量的变化。发现ＢＤ、ＡＤ患者双侧大脑半球灰质、白质血流量均明显低于对照组；ＢＤ患者双侧半球白质脑血流存在不对称性分布；大脑白质动脉对ＣＯ２扩张反应能力差。

A study on left ventricular function and spatial geometry was performed in 34 patients with AMI at the 28th day,33 patients with typical myocardial ischemia and 33 normal people by transthoratic and transesophageal two dimentional color Doppler echocardiography.The results showed that obvious alterations of LV shape and spatial geometry occured in more than a half of AMI patients and the potential alterations of LV ejection function existed in about 1/4 of AMI patients.The major change of LV spatial geometry was the enlargement of middle LV ring which would change left ventricle from its cone shape toward a global one.The main functional changes were decrease of EF,decline of myocardial constractivity and alteration of LV performance.
