Context: Elevated plasmatic microRNAs (miRs) are observed in heart failure (HF). However, the cardiac origin of these miRs remains unclear.Objective: We calculated transcoronary gradients miR-29b, miR-133a and miR-423-5p 17 outpatients with stable systolic HF controls without structural disease.Materials methods: MicroRNAs were measured by quantitative real-time polymerase chain reaction.Results: Positive miR patients but not (p = 0.03). B-type natriuretic peptide (BNP) moderately correlated...
O presente estudo revisou as abordagens diagnósticas e diferenças entre transtorno de estresse agudo pós-traumático, utilizando uma abordagem revisão integrativa. objetivo foi compreender distinções esses dois transtornos relacionados ao causado por eventos traumáticos, além aprimorar estratégias diagnósticas. A metodologia consistiu em integrativa realizada nas bases dados Scientific Electronic Library Online (SCIELO), Cochrane Medline, descritores ciências da saúde tema, como “Stress...
The Association between Different Measurements of Obesity and the Prevalence HypertensionPurpose -To evaluate association body mass index (BMI), waist-hip ratio waist circumference with prevalence hypertension in a representative sample 1088 adults Porto Alegre (RS), Brazil.Methods -In this cross-sectional survey, subjects were considered as having if they had systolic blood pressure 160mmHg or diastolic90mmHg, obese BMI 27kg/m 2 , waist-hip-ratio 0.95cm (men) 0.80 (women) 96 92...
The presumed proarrhythmic action of caffeine is controversial. Few studies have assessed the effect high doses in patients with heart failure due to left ventricular systolic dysfunction at risk for arrhythmias.To compare high-dose or placebo on frequency supraventricular and arrhythmias, both rest during a symptom-limited exercise test.Double-blinded randomized clinical trial crossover design conducted cardiac transplant clinic tertiary-care university hospital. included chronic...
Background: Headache is usually associated with high blood pressure (BP) despite the lack of evidence such an association in most observational studies.Ambulatory BP monitoring provides opportunity to analyze this relation because it permits measurement before, during, and after episodes headache. Methods:We evaluated 76 patients mild hypertension who underwent clinical evaluation, ambulatory monitoring, questioning about occurrence headache its characteristics during monitoring.The 24-hour...
Many randomized clinical trials have demonstrated the effectiveness of implantable cardioverter-defibrillator (ICDs) in death reduction chronic heart failure (CHF) patients. Some developed countries studies evaluated its cost-effectiveness, but these data are not applicable to Brazil.To evaluate cost-effectiveness ICD CHF patients under two perspectives Brazil: public and supplementary health systems.A Markov model was analyze incremental ratio (ICER) compared conventional therapy with CHF....
ResumenTanto la rumiación como preocupación constituyen procesos cognitivos repetitivos e improductivos.Diversas investigaciones han mostrado de manera sistemática sus consecuencias negativas en el bienestar emocional.La presente investigación evaluó infl uencia depresiva (incluyendo subfactores: refl exión y negativa), desarrollo sintomatología ansiosa una muestra 226 estudiantes universitarios.Se realizaron dos mediciones con un lapso 1 mes entre primera segunda.Se observaron asociaciones...
We investigated whether the combination of β 1 -Gly389Arg and GNB3 C825T, two genetic polymorphisms strictly related to adrenergic system modulation, could act as predictors appropriate therapies in patients with heart failure (HF) using implantable cardioverter-defibrillators (ICDs). Patients HF ICD implantation for primary secondary prevention were studied. All registered classified (secondary ventricular tachycardia) or inappropriate (others). Genetic analysis was performed by polymerase...
The coronavirus disease 2019 (COVID-19) is associated with cardiovascular clinical manifestations, including cardiac arrhythmias.To assess the incidence of arrhythmias (atrial tachyarrhythmia, bradyarrhythmia, and sustained ventricular tachycardia) arrest (CA) in a cohort patients hospitalized COVID-19 tertiary university-affiliated hospital.Cohort study retrospective analysis electronic medical records. For comparison between groups, value p <0.05 was considered statistically significant.We...
Objective: To analyze the dual interference between cardiac implantable electronic devices (CIEDs) and bioelectrical impedance analysis (BIA).Methods: Forty-three individuals admitted for CIEDs implantation were submitted to a tetrapolar BIA with an alternating current at 800 microA 50 kHz frequency before after devices' implantation.During assessment, continuous telemetry was maintained device programmer in order look evidence of possible electric intracavitary signal device.Results:...
Data from the international literature have shown changes in profile of cardiologists and their medical practices. However, there is no data on this Brazilian cardiologists.
