本研究运用门控平衡法心血池显象(MGBP)观察了心肌梗塞组(MI)30例,原发性高血压组(EH)20例及对照组(N)15例三组的左室局部射血分数(EF_(1～5)及局部轴缩短率(RS_(1～5)的变化.结果示MI组的局部EF及RS变化与梗塞部位基本一致;与N组比较各部位EF与RS均有显著差异(P<0.05～0.001)、EH组与N组比较除EF_4、RS_4的差异有显著性意义(P<0.05)以外,两级的其余EF、RS之间差异无显著性意义(P>0.05),提示左室局部EF及RS改变对判断MI及EH的病变部位和病情变化有一定的应用价值.
In this study, 30 cases of myocardial infarction (MI), 20 cases of essential hypertension (EH) and 15 cases of control (N) 15 cases of left ventricular regional The results showed that the changes of EF and RS in local group were basically the same as those in infarction group. Compared with group N, EF and RS (P <0.05 ~ 0.001). There were no significant differences between the two groups except for EF_4 and RS_4 in EH group and N group (P <0.05) P> 0.05), suggesting that changes in left ventricular EF and local changes in the determination of MI and EH lesions and disease has some value.
