Pulmonary hypertension(PH)is a hemodynamic disease characterized by persistently elevated pulmonary artery pressure.The clinical manifestations of PH patients are related to the severity of abnormal right ventricular function and right heart failure.Echocardiography has the advantages of convenience and non-invasiveness,and can be used to evaluate cardiac structure and function,and measure pulmonary artery pressure.It has become the preferred examination method for PH.With the continuous development of echocardiography technology,real-time three-dimensional echocardiography,three-dimensional speckle tracking technology,and echocardiography contrast have all played important roles in the diagnosis of PH.Echocardiography combined with other auxiliary examination methods can obtain more effective information in the examination of PH patients,providing evaluation basis for the diagnosis,treatment,curative effect evaluation and prognosis of PH patients.
