PH: pulmonary hypertension; PASP: pulmonary artery systolic pressure; BMI: body mass index; SBP: systolic blood pressure; FT₄: free thyroxine; FT₃: free triiodothyronine; TSH: thyroid-stimulating hormone; LVEF: left ventricular ejection fraction; CCB: calcium channel blockers; ACEI & ARB: ACE inhibitors and angiotensin II receptor antagonists. Data are presented as the mean ± standard deviation or as percentages.
