Abstract

Pulmonary hypertension due to left heart disease (PH‑LHD) is caused by left ventricular (LV) systolic and/or diastolic dysfunction and left heart valve disease. LV diseases lead to left ventricular filling pressure increases, pulmonary venous obstruction and pulmonary venous pressure increases, and thus to secondary PH. Exercise tolerance is lower and fatality rates are higher in patients with PH‑LHD than those in subjects with normal pulmonary arterial pressure. In spite of the progress in the study of the mechanisms of PH‑LHD in recent years, no specific treatment is currently available. The efficacy and safety of targeted therapies for pulmonary arterial hypertension remain to be fully established. In the present study, PH‑LHD patients were treated with milrinone injection. It was concluded that milrinone significantly reduces pulmonary artery systolic pressure (PASP) in patients with PH‑LHD, and significantly improves the cardiac structure, cardiac function and biochemical indexes. PASP was significantly correlated with the left atrial diameter, LV end diastolic diameter, LV ejection fraction, tricuspid annular plane systolic excursion, right ventricular fractional area change, N‑terminal pro‑B‑type natriuretic peptide and hypersensitive C‑reactive protein.
