Abstract Background: Recent epidemiological studies have shown that alterations in microbiota and its metabolites are associated with systemic arterial hypertension. Helicobacter pylori (H. pylori) is one of the most common bacterial pathogens, and the potential association between H. pylori infection and hypertension are controversial. Objective: This study aimed to clarify their association and provide a new theoretical basis for uncovering the pathogenesis of hypertension. Methods: Case-control and cross-sectional studies on the association between H. pylori and hypertension published from 1996 […]

Abstract Background In recent years, the incidence of infections related to cardiac implantable electronic devices (CIED) has increased sharply, impacting mortality. Objective To verify the proportion of patients with CIED infection; to analyze their clinical profile and the variables related to the infection and its progression. Methods Retrospective and longitudinal observational study including 123 patients with CIED infection among 6406 procedures. Parametric tests and a level of significance of 5% were used in the statistical analyses Results The mean age […]

Introduction In the midst of so many uncertainties that permeate the new coronavirus disease 2019 (COVID-19), the evidence relating the presence of dyslipidemia to disease severity and consequent prognostic implications are still scarce. In May 2020, a retrospective Chinese study investigated the association between changes in cholesterol levels and prognosis in approximately 600 patients with COVID-19, who were paired by age and sex with healthy controls. First, it was observed that low-density lipoprotein cholesterol (LDL-C) and total cholesterol levels were […]

Abstract Background The incidence of myocardial injury (MI) in patients with COVID-19 in Brazil and the prognostic impact of MI have not been elucidated. Objectives To describe the incidence of MI in patients with COVID-19 in the intensive care unit (ICU) and to identify variables associated with its occurrence. The secondary objective was to assess high-sensitivity troponin I as a predictor of in-hospital mortality. Methods Retrospective, observational study conducted between March and April 2020 with cases of confirmed COVID-19 admitted […]

Abstract Background Transvenous lead extraction (TLE) of cardiac implantable electronic devices (CIED) is an uncommon procedure and requires specialized personnel and adequate facilities. Objectives To evaluate the effectiveness and safety of the removal of CIED leads and to determine risk factors for surgical complications and mortality in 30 days. Methods Prospective study with data derived from clinical practice. From January 2014 to April 2020, we included 365 consecutive patients who underwent TLE, regardless of the indication and surgical technique used. […]
