Pulmonary Hypertension Clinical Trial
Official title:
Cardiac Speckle Tracking Myocardial Strain Balance Method: a New Method to Evaluate the Effect of Pulmonary Hypertension on the Prognosis
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.
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.
