Overview
Brief Summary
The investigators intend to evaluate the function of left heart and right heart and the motion balance between four chambers of the heart by speckle tracking technique during the follow-up of patients with pulmonary hypertension, and explore the relationship between the balance and prognosis of patients.
Detailed Description
Pulmonary hypertension is a fatal disease with progressive progressive vascular resistance that leads to the loss of right heart function. Right heart failure is the cause of death in most patients with end-stage pulmonary hypertension, and right heart function is also an important factor in determining the prognosis of patients. Echocardiography speckle tracking technology is a noninvasive technique for evaluating global and local cardiac function by tracking myocardial ultrasonic spots through computer image analysis technology and quantifying myocardial deformation. The investigators intend to evaluate the function of left heart and right heart and the motion balance between four chambers of the heart by speckle tracking technique during the follow-up of patients with pulmonary hypertension, and explore the relationship between the balance and prognosis of patients.
