Microvascular Dysfunction Is Associated With Impaired Myocardial Work in Obstru...
Garcia Brás, P; Aguiar Rosa, S; Cardoso, I; Branco, L; Galrinho, A; Valentim Gonçalves, A; Thomas, B; Viegas, JM; Fiarresga, A; Branco, G; Pereira, RBackground Two-dimensional speckle tracking echocardiography has been shown to correlate with microvascular dysfunction, a hallmark of hypertrophic cardiomyopathy (HCM). We hypothesized that there is an association between myocardial work and left ventricular ischemia, with incremental value to global longitudinal strain, in patients with HCM. Methods and Results We performed a prospective assessment of patient...
Myocardial Work Brings New Insights into Left Ventricular Remodelling in Cardio...
Vaz Ferreira, V; Mano, T; Cardoso, I; Coutinho Cruz, M; Branco, LM; Almeida-Morais, L; Timóteo, AT; Galrinho, A; Castelo, A; Garcia Brás, P; Simão, DSerial transthoracic echocardiographic (TTE) assessment of 2D left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) are the gold standard screening methods for cancer therapeutics-related cardiac dysfunction (CTRCD). Non-invasive left ventricular (LV) pressure-strain loop (PSL) provides a novel method of quantifying myocardial work (MW) with potential advantages to evaluate the impact o...

Impact of Repaired Aortic Coarctation in Left Ventricular Myocardial Work
Timóteo, AT; Branco, L; Galrinho, A; Rio, P; Sousa, L; Cruz Ferreira, RAims: 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...
Blunted Coronary Flow Velocity Reserve is Associated With Impairment in Systoli...
Aguiar Rosa, S; Rocha Lopes, L; Branco, L; Galrinho, A; Fiarresga, A; Thomas, B; Brás, P; Gonçalves, A; Cardoso, I; Papoila, A; Alves, M; Rio, PBackground Coronary microvascular dysfunction constitutes an important pathophysiological feature in hypertrophic cardiomyopathy (HCM). We aimed to assess the association between impaired coronary flow velocity reserve (CFVR) and ventricular systolic function and functional capacity. Methods Eighty-three patients with HCM were enrolled in this prospective cohort study. Patients underwent echocardiogram to evalu...
Prevalence and Prognostic Impact of Apical Sparing Contractility Pattern in Pat...
Ferreira, V; Aguiar Rosa, S; Pereira-da-Silva, T; Rodrigues, I; Gonçalves, A; Mendonça, T; Castelo, A; Branco, LM; Galrinho, A; Fiarresga, A; Ramos, RIntroduction: Prolonged afterload increase in aortic stenosis (AS) may alter left ventricular (LV) contractility, irrespective of LV ejection fraction (LVEF). The prevalence and morbimortality associated with the apical sparing strain pattern (ASP), a typical finding of cardiac amyloidosis (CA), are not fully understood in patients with AS. We assessed the prevalence of the ASP in patients with severe AS and it...
Three-Dimensional Speckle-Tracking Echocardiography for the Global and Regional...
Coutinho Cruz, M; Branco, LM; Portugal, G; Galrinho, A; Timóteo, AT; Rio, P; Ilhão Moreira, R; Mendonça, T; Leal, A; Gameiro, F; Duarte Oliveira, SBackground: Assessment of 2D/3D left ventricular ejection fraction (LVEF) and 2D global longitudinal strain (GLS) is the gold standard for diagnosing cancer therapeutics-related cardiac dysfunction (CTRCD). Although 3D speckle-tracking echocardiography (STE) has several advantages, it is not used in this setting. Methods: 105 breast cancer patients who underwent serial echocardiographic assessment during anthra...
Maximal Oxygen Uptake and Ventilation Improvement Following Sacubitril-Valsarta...
Valentim Gonçalves, A; Pereira-da-Silva, T; Galrinho, A; Rio, P; Soares, RM; Feliciano, J; Ilhão Moreira, R; Silva, S; Alves, S; Capilé, EBackground: Sacubitril/valsartan had its prognosis benefit confirmed in the PARADIGM-HF trial. However, data on cardiopulmonary exercise testing (CPET) changes with sacubitril-valsartan therapy are scarce. Objective: This study aimed to compare CPET parameters before and after sacubitril-valsartan therapy. Methods: Prospective evaluation of chronic heart failure (HF) patients with left ventricular ejection frac...
Antiarrhythmic Effect of Sacubitril-Valsartan: Cause or Consequence of Clinical...
Valentim Gonçalves, A; Pereira-da-Silva, T; Galrinho, A; Rio, P; Branco, LM; Soares, R; Feliciano, J; Ilhão Moreira, R; Cruz Ferreira, RSacubitril/Valsartan (LCZ696) reduced sudden cardiac death in the PARADIGM-HF trial. However, the mechanism by which LCZ696 reduces ventricular arrhythmias remains unclear. The aim of this study was to compare electrocardiographic (ECG) parameters and mechanical dispersion index, assessed by left ventricular (LV) global longitudinal strain (GLS), before and after LCZ696 therapy. We prospectively evaluated chron...
