Abstract Background Impaired left ventricular (LV) and right ventricular functions are important predictors of cardiovascular risk. Global longitudinal strain (GLS) provides superior sensitivity for assessing systolic function compared to traditional parameters, enhancing diagnostic accuracy in various cardiac conditions. However, GLS reference values in diverse populations are lacking. Objectives To establish reference values for LVGLS and right ventricular free wall longitudinal strain (RVFWLS) in a Brazilian multiethnic population without cardiovascular risk factors or disease. We also explore how clinical and echocardiographic […]

Abstract Background: In pulmonary hypertension (PH), the identification of easily obtainable prognostic markers associated with right ventricular (RV) dysfunction and survival is needed. Objective: To evaluate the association of red cell distribution width (RDW) with clinical, echocardiographic parameters and survival in patients with pre-capillary PH, with the development of a mortality prediction model. Methods: Observational, longitudinal, and prospective study conducted from May 2019 to December 2022. Thirty-four patients with pre-capillary PH underwent two-dimensional echocardiography and complete blood count. A cutoff […]
