The Diagnostic Value of Transthoracic Echocardiography Parameters Under the New Diagnostic Criteria for Pulmonary Hypertension.

ABSTRACT:

Background

In 2022, new guidelines for the diagnosis and treatment of pulmonary hypertension (PH) revised the hemodynamic definition, reducing the mean pulmonary artery pressure threshold from ≥ 25 to > 20 mmHg. The optimal threshold of transthoracic echocardiography (TTE) parameters and the predictive capability require further validation. This study aims to investigate the diagnostic value of TTE parameters under the new hemodynamic criteria.

Methods

Retrospective analysis of PH patients who underwent right heart catheterization and TTE examination between 2017 and 2022 in a single center. Logistic regression was employed to ascertain the predictive capacity of parameters across various conditions. Receiver operating characteristic curves were used to determine the optimal
