While the effects of instantaneous, single-bout exposure to hypoxia have been well researched, little is known about the autonomic response during, or as an adaptation to, repeated intermittent hypoxic exposure (IHE) in a sedentary population. Resting heart rate variability (HRV) and exercise capacity was assessed in 16 participants (8 receiving IHE,[Hyp] and 8 receiving a placebo treatment [C]) before and after a 4-week IHE intervention. Heart rate variability was also measured during an IHE session in the last week …

Objective: Analyze the influence of the measures body composition cardiovascular risk in elderly practitioners of physical activity. Method: This is an exploratory study, transversal and quantitative. Held from May to June 2015, in the municipality of João Pessoa/Paraíba, with elderly patrons of sport aerobics. Were selected for the study 21 people, with inclusion criteria does not own metallic structure in the body to prevent the measure through bioimpedance equipment octopolar InBody 720 and own age less than 60 years. Results …

We aimed to evaluate the associations of visceral adiposity with cardiometabolic risk factors in normal subjects with integrated 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT). A total of 58 normal subjects who underwent 18F-FDG PET/CT scan for cancer screening were included in this study. Volume and average Hounsfield unit (HU) of visceral adipose tissue (VAT) was measured from CT components of integrated PET/CT. Standardized uptake values (SUVmax) of liver, spleen …

Objective Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength, with the risk of frailty and poor quality of life. This study aimed to clarify the clinical characteristics of sarcopenia and to investigate the effects of comprehensive cardiac rehabilitation (CCR), including nutrition, physical exercise and medication, in patients with cardiovascular disease (CVD). Methods We retrospectively studied 322 inpatients with CVD (age 72±12 years). Muscle mass, muscle strength and …

The aim of this present study was to investigate if overweight individuals exhibit signs of vascular dysfunction associated with a high risk for cardiovascular disease (CVD). One hundred lean and 100 overweight participants were recruited for the present study. Retinal microvascular function was assessed using the Dynamic Retinal Vessel Analyser (DVA), and systemic macrovascular function by means of flow-mediated dilation (FMD). Investigations also included body composition, carotid intimal-media thickness (c-IMT) …

Background—Cardiac mass and volumes are often elevated in athletes, but it is not known whether moderate physical activity is also associated with cardiac dilatation and hypertrophy in a healthy adult population. Methods and Results—In total, 1096 adults (54% female, median age 39 years) without cardiovascular disease or cardiomyopathy-associated genetic variants underwent cardiac magnetic resonance imaging to determine biventricular volumes and function. Physical activity was assessed using a validated activity questionnaire. The …

Context: Although metabolic abnormalities are often developed in Asians with body mass index (BMI) of 23–25 kg/m2, the characteristics of the nonobese Asians with metabolic abnormality have not been fully understood. Objective: The aim of this study was to investigate the clinical significance of insulin sensitivity in Japanese men with BMI of 23–25 kg/m2. Design and Participants: In this study, we defined hypertension, hyperglycemia, and dyslipidemia as cardiometabolic risk factors (CMRFs). We recruited subjects who met the …

Background Both adaptive servoventilation (ASV) and nocturnal oxygen therapy improve sleep disordered breathing (SDB), but their effects on cardiac parameters have not been compared systematically. Methods and results 43 patients with chronic heart failure (CHF; left ventricular ejection fraction (LVEF)≤ 50%) with SDB were randomly assigned to undergo ASV (n= 19, apnoea hypopnoea index (AHI)= 34.2±12.1/h) or oxygen therapy (n= 24, 36.9±9.9/h) for 3 months. More than 70% of SDB events in both groups were central …

Background. Malnutrition (MN) is prevalent in cardiac surgery, but there are no specific preoperative risk factors of MN. The aim of this study is to assess the clinically relevant risk factors of MN for cardiac surgery patients. Materials and methods. The nutritional state of the patients was evaluated one day prior to surgery using a bioelectrical impedance analysis phase angle (PA). Two groups of patients were generated according to low PA: malnourished and well nourished. Risk factors of MN were divided into three clinically …
