Abstract:Objective To investigate the therapeutic value of Fasudil combined with noninvasive positive pressure ventilation in the treatment of acute exacerbation of chronic pulmonary heart disease. Methods A total of 98 hospitalized cases with acute exacerbation of chronic pulmonary heart disease were randomly divided into two groups. The control group (n = 48) received the conventional treatment of anti-infection, oxygen inhalation, airway dilation and expectorant together with noninvasive positive pressure ventilation. The observation group (n = 50) used Fasudil combined with the above treatment. The therapeutic effects were observed in the two groups. And the clinical parameters were compared before and after treatment between the two groups which included the arterial blood gas indexes (PaO2, SaO2, PaCO2, pH), respiratory rate (RR), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), pulmonary arterial pressure (PASP), endothelin-1 (ET-1), hypersensitive C-reactive protein (hs-CRP), tumor necrosis factor alpha (TNF-α) and N-terminal brain natriuretic peptide (NT-proBNP). Results The levels of pH, PaO2 and SaO2 significantly increased after treatment in the two groups (P < 0.05), and were significantly higher in the observation group (P < 0.05). After thetreatment, the levels of PaCO2, RR, HR, PASP, ET-1, hs-CRP and NT-proBNP significantly decreased in both groups (P < 0.05); the level of PASP decrease was significantly different between the two groups (P < 0.05). The clinical therapeutic effect of the observation group was better than that of the control group (P < 0.05). Conclusions Fasudil combined with noninvasive positive pressure ventilation therapy has certain therapeutic value in patients with acute exacerbation of chronic pulmonary heart disease, because the combined treatment can significantly improve the level of arterial blood gas indexes and reduce pulmonary artery pressure and inflammatory factor level.
