目的分析应用斑点追踪技术观察甲状腺功能亢进患者左心室心肌旋转及扭转运动的临床效果。方法 90例甲状腺功能亢进患者设为观察组,并依据患者的病程将其分为A组45例(病程<0.5年)和B组45例(病程≥0.5年),另选同期的45例体检健康者设为对照组,所有患者均通过超声心动图检查,分析其左心室心肌旋转及扭转运动检查结果。结果观察组患者治疗前左室短轴心底水平心内膜下心肌旋转角度峰值、左室短轴心底水平心外膜下心肌旋转角度峰值、心尖水平心内膜下心肌旋转角度峰值、心尖水平心外膜下心肌旋转角度峰值、左室心内膜扭转角度峰值、左室心外膜扭转角度峰值均明显高于对照组(P<0.05);治疗后以上指标均得到明显改善。结论应用斑点追踪技术能够较准确的观察甲状腺功能亢进患者左心室心肌旋转及扭转运动情况,具有良好的临床效果。
Objective To analyze the clinical effect of speckle tracking in left ventricular myocardial rotation and twisting in patients with hyperthyroidism. Methods Ninety patients with hyperthyroidism were divided into observation group (45 cases in group A) and group B (45 cases in group B) All healthy subjects were enrolled in the control group. All patients underwent echocardiography to analyze left ventricular myocardial rotation and torsional movement test results. Results Before treatment, the peak value of myocardial subarachnoid angle, the peak value of epicardial myocardial rotation angle, the peak value of subendocardial myocardial rotation angle, the apical level heart The peak value of epicardial rotation, the peak of left ventricular endocardial torsion angle and the peak of left ventricular epicardial torsion angle were significantly higher than those of the control group (P <0.05). The above indexes were significantly improved after treatment. Conclusion Speckle tracking technique can accurately observe left ventricular rotation and torsion in patients with hyperthyroidism and has good clinical effect.
