目的 :探讨小剂量甲状腺素片对老年充血性心衰的治疗效果。方法 :30例老年充血性心衰在常规治疗的基础上加用甲状腺素片 ,2 0 - 4 0mg/d ,并以 30例作对照 ,观察 4个月 ,对比治疗前后的功能改善情况 ,甲状腺素水平、左室舒张未期内径 (LVEDD)、左心室射血分数 (LVEF)、(CO)心排出量 ,E/A观察 ,心率、心律失常情况。结果 :两组的心功能均有改善 ,观察组优于对照组 (P <0 .0 1) ,血T3 、T4恢复至正常范围 ,观察组升高更明显 (P <0 .0 1)心功能均改善 ,观察组优于对照组 (P <0 .0 1)。结论 :小剂量甲状腺素长期治疗老年充血性心衰能显著改善心功能 ,无甲亢表现 ,不增加病死率
Objective: To investigate the therapeutic effect of low-dose thyroxine tablets on senile congestive heart failure. Methods: Thirty cases of senile congestive heart failure were treated with thyroxine (20-40 mg / d) on the basis of routine treatment. Thirty cases were used as control to observe the improvement of function before and after treatment. Thyroid (LVEDD), left ventricular ejection fraction (LVEF), (CO) cardiac output, E / A observation, heart rate and arrhythmia. Results: The heart function of both groups improved, the observation group was superior to the control group (P0.01), the blood T3 and T4 returned to the normal range, the observation group increased more obviously (P0.01) Function were improved, the observation group was better than the control group (P <0.01). Conclusion: Long-term treatment of low-dose thyroxine congestive heart failure can significantly improve cardiac function, no hyperthyroidism performance, does not increase the mortality
