摘要
对 2 5例原发性高血压、血压≥ 16 0 /90mmHg ,且经过心电图、心脏远达距离摄片、超声心动图检查 ,其中至少一项符合左心室肥厚 (LVH)标准的患者 ,进行磁共振扫描成像 (MRI) ,并与上述检测结果对比 ,以估价MRI对高血压性心脏病LVH的诊断价值。结果表明 ,MRI对LVH的诊断率 (96 % )明显高于超声心动图(5 6 % )、X线 (40 % )和心电图 (2 8% )对LVH的诊断率 (P均 <0 .0 1)。且MRI可测定收缩及舒张期室壁厚度 ,可对LVH准确分型 ,可对比心脏大小、心室容量及心肌重量。
To explore the diagnostic value of magnetic resonance imaging(MRI) in hypertensive heart disease,25 essential hypertension patients with left ventricular hypertrophy diagnosed by X ray,electrocardiogram,or echocardiography were examined by MRI.The results showed that the diagnostic sensitivify of MRI (96%) was higher than that of echocardiography (56%,P<0.01),X ray (40%,P<0.01) and electrocardiogram (28%,P<0.01). Moreover, MRI could accurately detect the types of left ventricular hypertrophy and observe the left ventricular mass and volume,so MRI could provide a better diagnostic method for hypertensive heart disease.
