| 目的观察瞬时波强（wave intensity，WI）技术评价甲亢患者左心室功能的价值。方法获取46例甲亢患者（甲亢组）及35例健康对照者（正常对照组）一般资料、常规超声心动图资料、WI参数，并比较两组间各指标有无统计学差异。结果甲亢组心率、收缩压高于正常对照组，舒张压低于正常对照组；甲亢组左室舒张末期内径（LVIDd）、左室舒张末期室间隔厚度（IVSd）、左室舒张末期容积（LVEDV）、左室收缩末期容积（LVESV）、每搏量（SV）、左室射血分数（LVEF）与正常对照组相比无明显差异，两组间其他参数均有明显差异；甲亢组瞬时加速度波强（W1）、第一峰到第二峰的时间间期（W1-W2）明显高于对照组，瞬时减速度波强（W2）、心电图的R波顶点到第一峰W1的时间间期（R-W1）明显低于对照组。结论WI技术作为一项通过动脉内血流动力学反映心脏功能的新指标，可快捷、客观、无创、有效地评价甲亢患者左心室功能。 |

| ObjectiveTo investigate the value of instantaneous wave intensity (WI) technic in respect of evaluating left ventricular function in patients with hyperthyroidism.Methods46 patients with hyperthyroidism and 35 healthy controls were divided into two groups.The general material,conventional ultrasonic cardiogram material,WI parameters were obtained and compared,and the two groups had statistical differences for each index.ResultsGeneral material:heart rate and systolic blood pressure of hyperthyroidism group was higher than that of normal control group,diastolic blood pressure was lower than normal control group,and no obvious difference was found in the rest indexes.Conventional echocardiography information:compared with the control group,in hyperthyroidism group LVIDd,LVISd,LVEDV,LVESV,SV,LVEF had no significant difference,but other parameters had significantly.WI parameters:hyperthyroidism W1,W1-W2 was significantly higher,W2,R-W1 was significantly lower than control group The difference was statistically significant.Conclusion WI technology as a new indicator to reflect cardiac function through the intra-arteries dynamic of blood flow,can be quick,objective,non-invasive,and evaluate left ventricular function of hyperthyroidism effectively. |
