中老年人群甲状腺激素与血清 NT-proBNP 的相关性研究分析

Correlation Analysis of Serum Thyroid Hormone NT-proBNP in Older Adults

目的：探讨中老年人群 N 端-脑钠肽前体（N-terminal pro-B-type natriuretic peptide，NT-proBNP）在甲状腺功能紊乱疾病中的变化及其相关性。方法采用电化学发光分析仪检测38例甲状腺功能亢进性心脏病（甲亢心组）、68例甲状腺功能亢进症（甲亢组）、31例甲状腺功能减退症（甲减组）患者及43例健康对照者血清 NT-proBNP 水平；对比分析各组别老年人群与中年人群血清 NT-proBNP 水平的差异，并分析其相关性。结果甲亢心组、甲亢组、甲减组与正常对照组血清 NT-proBNP 结果分别是827.61±626.13，107.18±54.46，162.94±134.14和68.76±39.21 pg／ml。甲亢心组、甲亢组、甲减组与正常对照组比较，血清 NT-proBNP 水平差异均有统计学意义（t ＝7.458，4.312，3.794；P ＝0.000，0.000，0.001）；甲亢心组、甲减组与甲亢组血清 NT-proBNP 水平比较差异有统计学意义（t＝7.078，2.232；P ＝0.000，0.032）。甲亢心组、甲减组、正常对照组老年人群血清 NT-proBNP 水平高于中年人群，差异有统计学意义（t ＝－3.216，－2.510，－2.653；P ＝0.007，0.016，0.014）；甲亢组老年人群血清 NT-proBNP 水平高于中年人群，但差异无统计学意义（t＝－0.140， P ＝0.890）。多元回归分析示甲亢组血清 NT-proBNP 水平与 FT4（r ＝0.224，P ＝0.033）存在正相关；甲减组血清 NT-proBNP 水平与 T3（r＝－0.363，P ＝0.022）存在负相关。结论中老年人群甲状腺功能紊乱对血清 NT-proBNP 的水平有显著性影响，血清 NT-proBNP 水平对不同甲状腺功能状态人群的辅助诊断和疗效观察具有一定临床价值。

Objective To discuss the aged people N-terminal pro-B-type natriuretic peptide （NT-proBNP）changes in thyroid function disorder and its correlation.Methods With electrochemical luminescence analyzer,detected serum NT-proBNP lev-el 38 patients with hyperthyroid heart disease,68 patients with hyperthyroidism,31 patients with hypothyroidism,and 43 ca-ses of healthy controls.Compared each groupserum NT-proBNP level of older population with middle-aged people,and anal-ysied the correlation.Results The serum NT-proBNP level of Hyperthyroidism heart group,hyperthyroidism,hypothyroid-ism group and normal control group were 827.61±626.13,107.18±54.46,162.94±134.14,68.76±39.21 pg/ml,respec-tively.The serum level of HT-pro BNP.Hyperthyroidism group,hyperthyroidism,hypothyroidism group compared with nor-mal control group,there were statistically significan（t = 7.458,4.312,3.794,P = 0.000,0.000,0.001）.Hyperthyroidism heart,hypothyroidism with hyperthyroidism group serum level of NT-proBNP comparison there was statistical significance（t=7.078,2.232;P = 0.000,0.032）.Hyperthyroidism heartgroup,hypothyroidism group and normal control group older population was higher than the level of serum NT-proBNP middle-aged,difference was statistically significant （t=-3.216,-2.510,-2.653;P =0.007,0.016,0.014）.Hyperthyroidism group of elderly serum NT-proBNP level higher than that of middle-aged people,but there was no statistically significant difference （t=-0.140,P =0.890）.Multiple regression analy-sis in hyperthyroidism group serum levels of NT-proBNP and FT4 had positive correlation （r=0.224,P =0.033）and hypo-thyroidismgroup serum levels of NT-proBNP and T3 had negative correlation （r=-0.363,P =0.022）.Conclusion Thy-roid dysfunction in elderly people for the level of serum NT-proBNP had significant influence.Auxiliary disgnosis and cura-tive effect observation of the serum level of NT-proBNP in people with different thyroid functional status has certain clinical value.
