Initial Single-Center Experience of a Standardized Protocol for Invasive Assess...
Vaz Ferreira, V; Ramos, R; Castelo, A; Mendonça, T; Almeida-Morais, L; Pereira-da-Silva, T; Oliveira, E; Viegas, J; Garcia Brás, P; Grazina, AIntroduction: Coronary vasomotion disorders (CVDs), including microvascular angina (MVA) and vasospastic angina (VSA), account for significant morbidity among patients with non-obstructive coronary artery disease (NOCAD). However, protocols for CVD assessment in clinical practice are seldom standardized and may be difficult to implement. Purpose: To assess the safety and feasibility of a comprehensive coronary ...
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...
Validation of a Heart Failure Risk Score in a Cohort of Cardiac Resynchronizati...
Cardoso, I; Cunha, P; Laranjo, S; Grazina, A; Viegas, J; Portugal, G; Valente, B; Lousinha, A; Brás, P; Brás, M; Cruz Ferreira, R; Oliveira, MThe heart failure risk status (HFRS) is a validated dynamic tool for risk score prediction, based on the TriageHF™ algorithm (Medtronic, Minneapolis, MN, USA), for the occurrence of a heart failure (HF) event in the 30 days following a remote monitoring (RM) transmission. The aim of this study was to evaluate the accuracy of the HFRS in predicting an unplanned hospital admission due to HF decompensation in a re...
Levosimendan in Outpatients with Advanced Heart Failure: Single-Center Experien...
Ferreira Reis, J; Gonçalves, A; Ilhão Moreira, R; Pereira-da-Silva, T; Timóteo, AT; Pombo, D; Carvalho, T; Correia, C; Santos, C; Cruz Ferreira, RIntroduction: Patients with advanced heart failure (HF) have high morbidity and mortality, with only a small proportion being eligible for advanced therapies. Intermittent outpatient levosimendan infusion has been shown to provide symptomatic relief and reduce the rate of HF events. Our aim was to assess the safety and efficacy of outpatient levosimendan administration in an advanced HF population. Methods: Thi...
Non-Vitamin K Oral Anticoagulants Assessment in High Risk of Bleeding Patients ...
Silva Cunha, P; Viveiros Monteiro, A; Coutinho Cruz, M; Malveiro, P; Reis, JP; Portugal, G; Dias, A; Cruz Ferreira, R; Oliveira, MMAtrial fibrillation (AF) is commonly associated with advanced age and the presence of multiple, concomitant acute and chronic health conditions, placing this population at high risk for serious therapeutic side effects. Nonvitamin K antagonist oral anticoagulants (NOACs) are increasingly used for stroke prevention in patients with atrial fibrillation. The purpose of this study was to investigate the effectivene...
Late Gadolinium Enhancement in the Left Ventricular Wall Is Associated with Atr...
Castelo, A; Aguiar Rosa, S; Fiarresga, A; Jalles, N; Vaz Ferreira, V; Garcia Brás, P; Branco, L; Oliveira, M; Cruz Ferreira, RPurpose: Atrial fibrillation (AF) is the most common arrhythmia in patients with hypertrophic cardiomyopathy (HCM). The aim of this study was to evaluate the relation between AF and left ventricular (LV) late gadolinium enhancement (LGE). Methods: 55 patients with HCM were retrospectively included. Patients were divided in HCM with AF and HCM without AF. Baseline clinical, echocardiographic and cardiovascular m...
Cancer Patients with Acute Coronary Syndrome Have Non-Superior Bleeding Risk Co...
Mano, T; Timóteo, AT; Aguiar Rosa, S; Belo, A; Cruz Ferreira, R; ProACS Registry InvestigatorsIntroduction: The management of acute coronary syndrome (ACS) in malignancy is challenging due to higher bleeding risk. Methods: We analyzed patients with cancer (active or in the previous five years) prospectively included in the ProACS registry between 2010 and 2019. Our aim was to assess safety (major bleeding, primary endpoint) and secondary efficacy endpoints (in-hospital mortality and combined in-hospital...
Long-Term Outcomes of Non-Contact Multi-Electrode Balloon Catheter Mapping-Guid...
Almeida, I; Lousinha, A; Silva Cunha, P; Valente, B; Paulo, M; Delgado, AS; Cruz Ferreira, R; Oliveira, MMIntroduction: The outflow tract (OT) regions of the ventricles are a common location of origin for idiopathic ventricular arrhythmias (VA). Non-contact mapping (NCM) with a multi-electrode balloon catheter Ensite-Array enables three-dimensional reconstruction of the geometry of the cardiac chambers and accurate mapping of the propagation map, based on a single beat analysis, facilitating the ablation and contri...
Associations Between Perfusion Defects, Tissue Changes and Myocardial Deformati...
Brás, P; Aguiar Rosa, S; Thomas, B; Fiarresga, A; Cardoso, I; Pereira, R; Branco, G; Cruz, I; Baquero, L; Cruz Ferreira, R; Mota Carmo, MBackground: Microvascular dysfunction is an often overlooked feature of hypertrophic cardiomyopathy (HCM). Our aim was to assess the association between microvascular dysfunction, wall thickness, tissue characteristics and myocardial deformation in HCM patients, by analyzing individual myocardial segments. Methods: Prospective assessment including cardiac magnetic resonance to assess wall thickness, T1 and T2 m...
Predictive Ability of Cardiopulmonary Exercise Test Parameters in Heart Failure...
Ferreira Reis, J; Valentim Gonçalves, A; Garcia Brás, P; Ilhão Moreira, R; Rio, P; Timóteo, AT; Soares, RM; Cruz Ferreira, RBackground: There is evidence suggesting that a peak oxygen uptake (pVO2) cut-off of 10ml/kg/min provides a more precise risk stratification in cardiac resynchronization therapy (CRT) patients. Objective: To compare the prognostic power of several cardiopulmonary exercise testing (CPET) parameters in this population and assess the discriminative ability of the guideline-recommended pVO2cut-off values. Methods: ...
