| 目的 观察峰值应变离散度（PSD）评估131I治疗前出现急性甲状腺功能减退（甲减）的分化型甲状腺癌（DTC）患者左心室功能和收缩同步性的价值。方法 纳入52例DTC 131I治疗前急性甲减患者为甲减组，以55名健康志愿者为对照组；获取常规超声心动图参数，应用二维斑点追踪成像技术获取左心室整体纵向应变（GLS）和峰值应变离散度（PSD），基底段、中间段和心尖段纵向收缩峰值应变（LPS）和纵向峰值应变达峰时间（TTPLS），比较组间超声参数差异。结果 甲减组室间隔舒张末期厚度、左心室后壁舒张末期厚度、左心室相对室壁厚度、PSD、基底段、中间段和心尖段TTPLS均大于，而E峰、e'、GLS、基底段、中间段及心尖段LPS均低于对照组（P均<0.05）。结论 PSD可早期定量、准确评估131I治疗前急性甲减DTC患者左心室功能和收缩同步性。 |

| Objective To explore the value of peak strain dispersion (PSD) for evaluating left ventricular function and systolic synchronicity in differentiated thyroid cancer (DTC) patients with acute hypothyroidism before 131I treatment. Methods A total of 52 DTC patients with acute hypothyroidism before 131I treatment were enrolled (hypothyroidism group), while 55 healthy volunteers were recruited as control group. Parameters of conventional echocardiography were obtained, and global longitudinal strain (GLS), peak strain dispersion (PSD), longitudinal peak strain (LPS) in basal, middle and apical segments and time to peak longitudinal strain (TTPLS) in basal, middle and apical segments were acquired on two-dimensional speckle tracking imaging, and the ultrasonic parameters were compared between groups. Results Interventricular septal thickness at end-diastole, left ventricular posterior wall thickness at end-diastole, relative wall thickness, PSD and TTPLS in basal, middle and apical segments in hypothyroidism group were higher, while E peak, e', GLS and LPS in basal, middle and apical segments were lower than those in control group (all P<0.05). Conclusion PSD could be used for early quantitative and accurate assessment of left ventricular function and systolic synchronicity in DTC patients with acute hypothyroidism before 131I treatment. |
