The Relationship of Resting Cardiopulmonary Function to Peak and Submaximal Cardiopulmonary Exercise Testing in Older Adults with Heart Failure
Background: Heart failure (HF) is a challenging disease that affects more than five million people, half of whom are at least 75 years old. Peak oxygen consumption (VO2peak), the minute ventilation/carbon dioxide production (VE/VCO2) slope, and the 6MWT are powerful prognostic indicators of …

Unexplained Exercise Intolerance and Dyspnea in Long COVID
… by persistent dyspnea, fatigue, and exercise intolerance despite normal cardiopulmonary findings. This study examined whether peripheral impairments—specifically respiratory muscle dysfunction and endothelial impairment—contribute to these symptoms. Thirty COVID-19 convalescent adults …

CHANGES IN VE/VCO2 SLOPE OVER TIME IN LVAD RECIPIENTS
Abstract Background: Cardiopulmonary exercise testing (CPET) is essential in the evaluation of patients with heart failure (HF), including left ventricular assist devices (LVADs) recipients. Peak oxygen uptake (pVO2) and VE/VCO2 slope are key prognostic parameters, but their values after LVAD …

Obstructive Sleep Apnea Risk in Abdominal Aortic Aneurysm Disease Patients: Associations with Physical Activity Status, Metabolic Syndrome, and Exercise Tolerance
… activity (PA), metabolic syndrome (MetSyn), and exercise responses to cardiopulmonary exercise testing (CPET) in elderly patients with AAA disease. Methods: Elderly patients (n=326 for Studies 1 and 2; n=114 for Study 3) newly diagnosed with small AAAs (aortic diameter "2.5 and < 5.5 cm) were …

Cardiovascular Functional Alterations in Chronic Kidney Disease
… rather than ascertainment under the stress of exercise, may not accurately reflect the risk of premature death in CKD. The problem is that the natural history and progression of cardiovascular functional alterations across the CKD spectrum is largely unknown. Additionally, few studies have …

A Comparison of Maximal Exercise Responses among Patients with a Total Artificial Heart, a Left Ventricular Assist Device, or Advanced Heart Failure
The purpose of this study was to evaluate graded exercise responses to treadmill exercise in patients with a total artificial heat (SynCardia, Tucson, AZ). Additionally, this study sought to compare the exercise response in total artificial heart (TAH) patients to both advanced heart failure (HF) …

Auswirkung von körperlicher Belastung auf die Konzentration von 3-Nitrotyrosin im Atemkondensat
… breath condensate (EBC) caused by physical exercise testing. They were separated in 10 atopic and 10 non-atopic probands. Each group contained 5 smokers and 5 non-smokers. Eventually we got four groups of probands: 1. smoker/atopics; 2. smoker/ non-atopics; 3. non-smoker/atopics; 4. …

The Effects of Exercise Training On the Severity and Health Consequences of Obstructive Sleep Apnea
… and experimental evidence, the efficacy of exercise training has been scarcely explored for the management of OSA. These studies were designed to establish the efficacy of exercise training on (1) OSA severity and overall sleep quality, (2) daytime functioning and neurobehavioral …

Mechanisms and Management of Breathlessness in Chronic Heart Failure
… relief, but ventilation was not matched. 4) Cardiopulmonary exercise testing (CPET) produced an average VO2peak of 54±15% predicted, with a measurable anaerobic threshold in 73% of tests and raised dyspnoea to 42±19%VAS. 5) Nebulised furosemide resulted in no significant improvements in …

EFFECTS OF ACUTE NORMOBARIC HYPOXIA DURING EXERCISE AND CONCURRENT MENTAL STRESS ON THE CARDIOVASCULAR SYSTEM IN HEALTHY ATHLETES
BACKGROUND: Exercise and hypoxia are individually recognized as physiological stressors that challenge cardiovascular homeostasis through mechanisms orchestrated by medullary cardiovascular control centers. During physical exertion, the activation of the “exercise pressor reflex” facilitates …
