分析血塞通，硝酸甘油，多巴胺联合治疗慢性肺源性心脏病心力衰竭的临床价值

Objective To investigate the application effect of combined treatment with Xuesaitong, nitroglycerin, and dopamine for chronic pulmonary heart disease with heart failure. Methods A total of 80 patients with chronic pulmonary heart failure who were treated in the Department of Cardiology of Luodian County Traditional Chinese Medicine Hospital in Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province from December 2022 to December 2024 were enrolled. The patients were divided into two groups using the random number table method, with 40 cases in each group. The control group received conventional treatment, while the study group received combined treatment with Xuesaitong, nitroglycerin, and dopamine on the basis of conventional treatment. The disappearance time of clinical symptoms such as cough, sputum, and dyspnea was compared between the two groups, as well as the cardiac function indicators of left ventricular ejection fraction, 6-minute walking test, and N-terminal pro-B-type natriuretic peptide (NT-proBNP), and the pulmonary function indicators of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and FEV1/FVC. Results The improvement time of clinical symptoms such as cough, sputum, and shortness of breath in the study group was shorter than that in the control group (P＜0.05). After 2 weeks of treatment, left ventricular ejection fraction and 6-minute walking test results increased significantly in both groups (P＜0.05), and the study group achieved better outcomes than the control group (P ＜0.05) ; The NT-proBNP of both groups decreased (P＜0.05), and the study group was lower than the control group (P＜0.05). After 2 weeks of treatment, the FVC, FEV1, and FEV1/FVC of both groups were improved (P＜0.05), and the study group was higher than the control group (P＜0.05). Conclusion Combined treatment with Xuesaitong, nitroglycerin, and dopamine can effectively shorten the improvement time of clinical symptoms of chronic pulmonary heart disease with heart
