Resumo Fundamento: A citocina fator de necrose tumoral alfa (TNF-α) é elevada na hipertensão resistente (HAR), mas os efeitos dos inibidores de TNF-α nessa população ainda são desconhecidos. Objetivos: O objetivo deste estudo foi avaliar se uma única dose de infliximabe controlada por placebo reduz a pressão arterial (PA) de forma aguda em pacientes com HAR. Métodos: Realizamos um estudo cruzado, randomizado, d...
Resumo Fundamento O fenômeno de no-reflow após a intervenção coronária percutânea está associado a um pior prognóstico em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST). O escore SYNTAX é um bom preditor de no-reflow. Objetivo Nosso objetivo foi avaliar se a carga aterosclerótica (escore Gensini) e a carga trombótica na artéria coronária culpada melhorariam a capacidade do e...
Abstract Background: There is evidence that subclinical systemic inflammation is present in resistant hypertension (RHTN). Objective: The aim of the study was to develop an integrated measure of circulating cytokines/adipokines involved in the pathophysiology of RHTN. Methods: RHTN (n = 112) and mild to moderate hypertensive (HTN) subjects (n=112) were studied in a cross-sectional design. Plasma cytokines/adipo...
Abstract Background: Metabolic syndrome (MetS) is widespread among hypertensive patients. Clinical features and potential biomarkers of MetS in the presence of hypertension and resistant hypertension (RHTN) represent a great area of interest for investigation. Objective: The purpose of this study was to evaluate the prevalence of MetS and the clinical features associated with it in resistant and mild to moderat...
Abstract Background: Balloon post-dilatation (BPD) is often needed for optimizing transcatheter heart valve (THV) implantation, since paravalvular leak (PVL) after transcatheter aortic valve implantation is associated with poor outcome and mortality. Quantitative assessment of PVL severity before and after BPD is mandatory to properly assess PVL, thus improving implantation results and outcomes. Objective: To i...
Abstract Background: Hypertension is a chronic, low-grade inflammation process associated with the release of cytokines and development of target organ damage. Deregulated monocyte chemoattractant protein-1 (MCP-1) levels have been associated with high blood pressure and cardiovascular complications; however, the mechanisms involved are complex and not fully understood. Objective: This study aimed to compare th...
Resistant hypertension (RHTN) is a multifactorial disease characterized by blood pressure (BP) levels above goal (140/90 mmHg) in spite of the concurrent use of three or more antihypertensive drugs of different classes. Moreover, it is well known that RHTN subjects have high prevalence of left ventricular diastolic dysfunction (LVDD), which leads to increased risk of heart failure progression. This review gathe...
