Introduction Obstructive sleep apnea (OSA) is a common condition characterized by recurrent upper airway obstructions during sleep, promoting intermittent hypoxia and sleep fragmentation. Traditional risk factors for OSA include male gender and obesity. Overall, patients with severe OSA presented longer events and more severe hypoxemia. Supine sleep is consistently associated with more severe OSA rates in adults. However, the relationship between OSA indices and prone position is inconsistent. Here, we reported a very peculiar presentation of OSA characterized by very […]

Abstract Background: Higher body mass index (BMI) has been associated with improved outcomes in heart failure with reduced ejection fraction. This finding has led to the concept of the obesity paradox. Objective: To investigate the impact of exercise tolerance and cardiorespiratory capacity on the obesity paradox. Methods: Outpatients with symptomatic heart failure and left ventricular ejection fraction (LVEF) ≤ 40%, followed up in our center, prospectively underwent baseline comprehensive evaluation including clinical, laboratorial, electrocardiographic, echocardiographic, and cardiopulmonary exercise testing parameters. […]

Abstract Background The proportion of arterial hypertension (AH) has increased in children and adolescents and is associated with several comorbidities. Objective To verify the association of arterial hypertension with central and general obesity as well as according to the level of physical activity in schoolchildren. Methods 336 children and adolescents aged 11 to 17 participated in the study. Height, body weight, waist circumference (WC) and blood pressure (BP) were measured. The body mass index z-score (BMI-z) was calculated. The level […]

Background: Prosthesis-patient mismatch (PPM) is associated with worse outcomes. Objective: Determine the frequency and evaluate preoperatory variables independently associated with severe PPM in a tertiary hospital focused on Public Health Care. Methods: A total of 316 patients submitted to aortic valve replacement, who had echocardiography performed within the first 30 days after surgery, were retrospectively analyzed. The indexed effective orifice area (iEOA) of the prosthesis was used to classify the patients into three groups, according to PPM, considering body mass […]
