ABSTRACT
Objective:To explore the correlation between right atrial function parameters and prognosis in patients with chronic obstructive pulmonary disease(COPD) complicated with pulmonary hypertension.Methods:Eighty-four patients with COPD combined with pulmonary arterial hypertension treated with bosentan combined with milrinone admitted to the First Affiliated Hospital of Xinjiang Medical University during the period of February 2020 to June 2022 were selected as the study subjects, and they were divided into the effective group (63 cases) and the ineffective group (21 cases) according to the treatment effect. Right cardiac function parameters were measured by Philips iE33 color ultrasonography before treatment and 72 h after treatment. Logistic regression was used to analyze the risk factors affecting the treatment outcome of patients, and receiver operating characteristics (ROC) curve was used to analyze the predictive value of right atrial function parameters in the poor prognosis of patients with COPD complicated with pulmonary hypertension.Results:The main pulmonary artery diameter (MPA), right ventricular base transverse diameter (RVd1), right ventricular middle transverse diameter (RVd2), right atrial diameter (RAd) and right ventricular free wall thickness (RVWT) in the effective group were lower than those in the ineffective group: (2.65 ± 0.23) cm vs. (2.90 ± 0.44) cm, (3.46 ± 0.43) cm vs. (3.76 ± 0.72) cm, (3.48 ± 0.42) cm vs. (3.88 ± 0.69) cm, (3.53 ± 0.81) cm vs. (4.03 ± 1.20) cm, (0.63 ± 0.12) cm vs. (0.72 ± 0.21) cm; end-diastolic to end-systolic tricuspid ring displacement (TAPSE) was higher than that in the ineffective group: (2.08 ± 0.32) cm vs. (1.82 ± 0.46) cm, there were statistical differences( P<0.05). Logistic regression analysis showed that RVd1 increased ( OR = 3.717, P<0.05), RVd2 increased ( OR = 2.162, P<0.05), RAd increased ( OR = 2.838, P<0.05) and TAPSE reduction ( OR = 1.704, P<0.05) were risk factors for treatment failure in patients. The results of ROC curve showed that the area under the curve of RVd1, RVd2, RAd, TAPSE in predicting the therapeutic effect of COPD patients with pulmonary hypertension were 0.820, 0.831, 0.872, 0.909, respectively. Conclusions:The independent influencing factors of ineffective patients with COPD combined with pulmonary arterial hypertension treated with bosentan combined with milrinone are the increase of structural parameters of the right heart and the decrease of systolic function parameters. The therapeutic effect of patients can be evaluated clinically according to the level of each parameter.
