Abstract:【Objective】To investigate the effects of low molecular weight heparin calcium on cardiopulmonary function, BNP (brain natriuretic peptide) levels and inflammatory status in patients with COPD (chronic obstructive pulmonary disease) complicated with pulmonary heart disease. 【Methods】A total of 97 patients with COPD complicated with pulmonary heart disease who were treated in our hospital from March 2016 to March 2018 were randomly divided into the observation group (49 cases) and the control group (48 cases). The control group was treated with conventional treatment measures, and the observation group was treated with low molecular weight heparin on the basis of the control group. One week after treatment, the changes of coagulation function, lung function and blood gas index before and after treatment were observed. The BNP levels and inflammatory status of the two groups were analyzed before and after treatment. 【Results】The prothrombin time (PT), activated partial thromboplastin time (APTT), blood oxygen saturation (SpO2), arterial oxygen partial pressure (PaO2), one second forced expiratory volume (FEV1), the first-second forced expiratory volume occupancy capacity (FEV1/FVC) and one second rate (FEV1%) in the observation group were significantly higher than the control group. The D-dimer (DD) content and arterial blood carbon dioxide partial pressure were significantly lower than the control group; the difference between the two groups was statistically significant (P<0.05). Brain natriuretic peptide (BNP), interleukin 6 ( The levels of IL-6), tumor necrosis factor (TNF-α) and high-sensitivity C-reactive protein (hs-CRP) in the observation group were significantly lower than the control group, and the difference was statistically significant (P<0.05). 【Conclusion】Low molecular weight heparin calcium in patients with COPD complicated with pulmonary heart disease can improve cardiopulmonary function and reduce BNP levels and inflammatory response in patients.
