Left ventricular global longitudinal strain is associated with filling pressure...

Publisher Copyright: © 2024 Sociedade Portuguesa de Cardiologia; Introduction and objectives: Left ventricular global longitudinal strain (LVGLS) is an indicator of myocardial function in patients with heart failure with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). Nevertheless, it is not clear whether LVGLS correlates with filling pressures and cardiac output (CO) in an ambulatory...

Global left ventricular myocardial work index and medium-term adverse cardiovas...

Publisher Copyright: © 2024 The Author; Background: Left ventricular global longitudinal strain (GLS) has incremental prognostic value over ejection fraction (EF) in patients with ST-segment-elevation myocardial infarction (STEMI), but it is also load dependent. It has been recently demonstrated that Myocardial work (MW), integrating blood pressure with GLS, predicts long-term all-cause mortality. We aimed to f...

Sacubitril/Valsartan Improves Left Atrial and Ventricular Strain and Strain Rat...

Background: Data on the impact of sacubitril/valsartan (SV) therapy on phasic left atrial (LA) and left ventricular (LV) strain in heart failure with reduced ejection fraction (HFrEF) are limited. The aim of this study was to evaluate changes in two-dimensional speckle tracking (2D-STE) parameters with SV therapy in HFrEF patients. Methods: Prospective evaluation of HFrEF patients receiving optimized medical th...

Cardiopulmonary Exercise Testing in the Age of New Heart Failure Therapies

Background: New therapies with prognostic benefits have been recently introduced in heart failure with reduced ejection fraction (HFrEF) management. The aim of this study was to evaluate the prognostic power of current listing criteria for heart transplantation (HT) in an HFrEF cohort submitted to cardiopulmonary exercise testing (CPET) between 2009 and 2014 (group A) and between 2015 and 2018 (group B). Method...

Age Differences in Cardiopulmonary Exercise Testing Parameters in Heart Failure...

Background and Objectives: Cardiopulmonary exercise testing (CPET) is a cornerstone of risk stratification in heart failure with reduced ejection fraction (HFrEF). However, there is a paucity of evidence on its predictive power in older patients. The aim of this study was to evaluate the prognostic power of current heart transplantation (HTx) listing criteria in HFrEF stratified according to age groups. Materia...

Cardiopulmonary Exercise Testing in Patients with Heart Failure

BACKGROUND: Exercise testing is key in the risk stratification of patients with heart failure (HF). There are scarce data on its prognostic power in women. Our aim was to assess the predictive value of the heart transplantation (HTx) thresholds in HF in women and in men. METHODS: Prospective evaluation of HF patients who underwent cardiopulmonary exercise testing (CPET) from 2009 to 2018 for the composite endpo...

Impacto da coartação da aorta reparada no trabalho miocárdico ventricular esquerdo

Aims: Myocardial strain analysis enables more precise assessment of cardiac performance but is relatively load dependent. New tools have been developed with afterload adjustment. Our objective was to assess myocardial work (MW) in patients with repaired aortic coarctation (rACo). Methods: Prospective study of consecutive patients with rACo who underwent a routine transthoracic echocardiogram in 2018 and 2019 at...

Preditores de resposta à terapêutica de ressincronização cardíaca

Funding: This work was supported by research grant PTDC/DES/120249/2010 from the Foundation for Science and Technology (FCT).; Introduction Cardiac resynchronization therapy (CRT) has modified the prognosis of chronic heart failure (HF) with left ventricular systolic dysfunction. However, 30% of patients do not have a favorable response. The big question is how to determine predictors of response. Aims To ident...
