Relationship Between Thyroid Hormone and Atrial Fibrillation Prevalence in Patients With Chronic Heart Failure / 中国循环杂志

ABSTRACT

Objective: To investigate the impact of thyroid hormone on atrial ifbrillation (AF) prevalence in patients with chronic heart failure (CHF). Methods: A total of 322 non-valvular heart disease CHF patients treated in our hospital from 2011-0-01 to 2012-10-01 were retrospectively studied. Based on previous history and the ECG at admission, the patients were divided into 2 groups: AF group,n=187 and Sinus rhythm group,n=135. The proifle of serum levels of free thyroxine (FT4), free triiodothyronine (FT3), hyroid stimulating hormone (TSH) and LDL-C were examined within 24 hours of admission; 12 lead ECG and echocardiography were conducted to analyze the related factor for AF occurrence. Results: Compared with Sinus rhythm group, AF group had increased FT4 level as 14.52 (12.74, 15.85) pmol/L vs 13.11 (11.68, 14.85) pmol/L,P Conclusion: High serum level of FT4 may increase the risk AF occurrence in CHF patients.
