Objective: To explore the application value of myocardial work (MW) technique in evaluating right ventricular systolic function in patients with severe pulmonary hypertension (sPH). Methods: A total of 30 patients diagnosed with sPH and 30 healthy people from November 2020 to April 2022 in our hospital were selected and divided in to the sPH group (n=30) and the control group(n=30). Routine echocardiography data were collected for right ventricular myocardial work analysis. The parameters included right ventricular global work index (RVGWI), right ventricular global active work index (RVGCW), right ventricular global idle work index (RVGWW), and right ventricular global work efficiency (RVGWE). The differences of MW parameters between the two groups were compared. Results: RVGWE in the sPH group was significantly lower than that in the control group (P＜0.01), RVGWI and RVGCW increased (P＜0.01), RVGWW increased significantly (P＜0.01). Conclusion: MW technology can accurately evaluate the right ventricular systolic function in patients with sPH, which could provide innovative and reliable data for clinical practice.
