原发性高血压病患者心肌肥厚的三种检测方法比较

Comparison of Three Detective Methods of Myocardiohypertrophy in Essential Hypertension

用三种检测方法(超声心动图、心电图、x 线)比较46例高血压病人的心肌肥厚变化。46例中男24例,女22例。年龄在19～73岁之间。Ⅰ期高血压4例,Ⅱ期41例,Ⅲ期1例。对照组健康人53名(男33例,女20例),年龄在22～64岁之间。其检查结果:超声心动图检查室间隔和(或)左室肥厚为56.52％,不对称性室间隔肥厚为38.46％,向心性肥厚为61.54％,心电图提示左室肥厚(包括左室高电压)为26.6％,常规 x 线为40％,三种检测方法比较,有统计学意义P<0.01),提示超声心动图比心电图及 x 线敏感。

Three detective methods (Echocardiography,ECG,the routine Chest X-ray) for comparing the changes of heart structure and functions in 46 cases of systemic hypertension were reported.There were found abnormally increased ventricular septal and/or posterior wall myocardium thickness in 56.52% of the hypertensive subjects,38.46% of the patients had asymmetrical septal thinkness,61.54% had centripe-tal hypertrophy (i.e.IVS to LVPW ratio=1.3),26.6% of the patients had abnormal ECG,and 40% had abnormal chest X-ray,the echocardigram appeared to be superier to the ECG and the chest X-ray for detecting cardiac hypertrophy in essential hypertension (P<0.01).
