脑梗死后血清甲状腺激素水平与康复预后的关系

摘要

Objective To investigate the relationship between serum thyroid hormone level and prognosis after cerebral infarction.Methods Serum thyroid hormone level was determined in 88 patients with partial anteri-or circulation infarction(PACI)and large artery atherosclerotic(LAA)cerebral infarction.After 6-months rehabili-tation,the difference of serum thyroid hormone level was compared among all groups. Results Significant differ-ences of serum free triiodothyronine(FT3)were observed in patients with different prognosis(P < 0.01). Signifi-cant correlation was found between the low level FT3and the good prognosis(P < 0.01). Conclusions The de-crease of serum thyroid hormone level after cerebral infarction is protective,and the FT3level is negatively correlat-ed with the prognosis of patients with cerebral infarction.%目的 观察脑梗死后血清甲状腺激素水平与康复预后的关系,探讨其意义.方法 检测了88例部分前循环梗死、大动脉粥样硬化型脑梗死患者血清甲状腺激素浓度,康复治疗6个月后,根据疗效分组,比较各组甲状腺激素浓度的差异.结果 康复预后不同,血清游离三碘甲状腺原氨酸(FT3)浓度差异有显著性(P<0.01),且FT3浓度越低,康复预后越佳(P<0.01).结论 脑梗死后血清甲状腺激素水平下降是机体的自我保护,FT3越低,患者康复预后越佳.
