Abstract:
Objective To investigate the diagnostic efficacy of multimodal echocardiography on right heart function in patients with pulmonary hypertension.Methods A total of 80 patients with pulmonary hypertension treated in Jinhua Municipal Center Hospital from January 2022 to August 2023 were selected into observation group,and they were divided into mild group[40-50mmHg(1mmHg=0.133kPa),36 cases],moderate group(51-70mmHg,20 cases)and severe group(>70mmHg,24 cases)according to their pulmonary artery systolic blood pressure.A total of 80 healthy subjects were included in control group.All subjects underwent multimodal echocardiography.The diagnostic efficacy of multimodal echocardiography on right ventricular systolic function in patients with pulmonary hypertension was evaluated by comparing the data of subjects.Results Right ventricular end diastolic volume(RVEDV),right ventricular end systolic volume(RVESV),right ventricular global waste work(RVGWW)in observation group were significantly higher than those in control group,while right ventricular stroke volume(RVSV),right ventrical ejection fraction(RVEF),tricuspid annular plane systolic excusion(TAPSE),global longitudinal strain(GLS),right ventricular global work efficiency(RVGWE),right ventricular global work index(RVGWI),right ventricular global constructive work(RVGCW)were significantly lower than those in control group(P<0.05).RVEDV,RVESV and RVGWW in severe group were significantly higher than those in moderate and mild groups,while RVSV,RVEF,RVGWE,RVGWI and RVGCW were significantly lower than those in moderate and mild groups(P<0.05).The area under the curve of TAPSE,GLS,RVSV,RVEF and RVGWI in combined diagnosis of right heart function in patients with pulmonary hypertension was 0.911,the sensitivity was 92.23%and the specificity was 96.45%.Conclusion Multimodal echocardiography can effectively evaluate right ventricular systolic function in patients with pulmonary hypertension and is worthy of clinical application.
