Serum-Free Thyroxine Levels Were Associated with Pulmonary Hypertension and Pulmonary Artery Systolic Pressure in Euthyroid Patients with Coronary Artery Disease

Table 2

Comparison of thyroid function parameters among subgroups with different pulmonary artery systolic pressures.

	Non-PH; ()	Mild PH; ()	Moderate-to-severe; PH ()	Model 1; value	Model 2; value
FT3	4.32 ± 0.56	4.28 ± 0.68	4.18 ± 0.74	0.40	0.38
FT4	15.30 ± 2.07	15.75 ± 2.31	16.80 ± 2.94^#	<0.01	0.01

PH: pulmonary hypertension; FT₄: free thyroxine; FT₃: free triiodothyronine; TSH: thyroid-stimulating hormone; Model 1: unadjusted; Model 2: adjusted for age, gender, BMI, and LVEF. Data are presented as the mean ± standard deviation. versus the non-PH group, ^# versus the mild PH group.
