Efficacy Of Beraprost Sodium Combined With Sildenafil And Its Effects On Vascular Endothelial Function And Inflammation In Patients Experiencing Left Heart Failure Complicated With Pulmonary Arterial Hypertension

Background: To explore the efficacy of beraprost sodium combined with sildenafil and its effects on the vascular endothelial function and inflammation in left heart failure patients complicated with pulmonary arterial hypertension.Material/Methods: A total of 80 patients with left heart failure complicated with pulmonary arterial hypertension was enrolled as the subjects of this study and assigned into an observation group (n=40) and a control group (n=40) using a random number table. The changes in pulmonary arterial hypertension-associated indicators at 3 months after treatment and the alterations in the levels of cardiac function-associated biochemical indicator brain natriuretic peptide (BNP), inflammatory factor tumor necrosis factor alpha (INF-alpha), and mean pulmonary arterial pressure during treatment were compared between the 2 groups.Results: At 3 months after treatment, the pulmonary arterial hypertension-associated indicators human urotensin II and calcitonin gene-related peptide in the observation group were lower and higher, respectively, than those in control group. Moreover, the observation group had significantly lower BNP and TNF-alpha levels and mean pulmonary arterial pressure than the control group. After intervention, the echocardiographic parameters left ventricular ejection fraction (LVEF), cardiac output (CO), and stroke volume (SV) in both groups were significantly higher than those before intervention, and the observation group had significantly higher LVEF, SV, and CO than the control group after intervention.Conclusions: Beraprost sodium combined with sildenafil for left heart failure complicated with pulmonary arterial hypertension can effectively improve pulmonary arterial hypertension, alleviate left heart failure, and reduce inflammatory responses, thereby achieving better clinical efficacy in patients.
