Pulmonary hypertension(PH)is a pathophysiological syndrome that involves a variety of clinical symptoms and may be associated with a variety of cardiovascular and respiratory diseases.Patients with PH most often die of right heart failure,so accurate evaluation of right ventricular function in patients with PH can provide effective clinical information about the severity of the condition,responsiveness to treatment,and prognosis.Echocardiography is the most commonly used clinical examination method to evaluate right ventricular systolic function and estimate pulmonary artery pressure in patients with PH.With the development of new technologies,the emergence of new ideas and indicators for evaluating right ventricular function has become inevitable.New progress in the study of ultrasound noninvasive evaluation of right ventricular systolic function in patients with PH is reviewed in this article.
