Peak oxygen consumption (pVO2) measured by cardiopulmonary exercise test (CPET) predicts mortality in adults with a Fontan circulation. The purpose of this study was to assess the additive prognostic value of change in pVO2 over time. METHODS: We analyzed a cohort of adults (≥18 years old) with a Fontan circulation who underwent at least 2 maximal CPETs separated by 6-30 months at Boston Children's Hospital between 2000 and 2015. Survival analysis was performed to determine whether changes in CPET variables, including pVO2 between consecutive tests, were associated with subsequent clinical events...

OBJECTIVES: The aim was to investigate whether cardiopulmonary exercise testing (CPET) variables derived from cycle and arm ergonometry correlate, and whether CPET variables and pre-operative N-terminal pro-brain natriuretic peptide (NT-proBNP) have prognostic significance and if the combination of the two has incremental value. METHODS: A prospective observational pilot study was conducted; 70 patients who underwent infra-inguinal bypass surgery were recruited...

Tetralogy of Fallot is the most common form of cyanotic congenital heart disease. As a result of the surgical strategies employed at the time of initial repair, chronic pulmonary regurgitation (PR) is prevalent in this population. Despite sustained research efforts, patient selection and timing of pulmonary valve replacement (PVR) to address PR in young asymptomatic patients with repaired tetralogy of Fallot (rToF) remain a fundamental but as yet unanswered question in the field of congenital heart disease...

Cardiopulmonary exercise testing (CPET) aids in clinical assessment of patients with Fontan circulation. Effects of persistent fenestration on CPET variables have not been clearly defined. Associations between fenestration and CPET variables at anaerobic threshold (AT) and peak exercise were explored in the Pediatric Heart Network Fontan Cross-Sectional Study cohort. Fenestration patency was associated with a greater decrease in oxygen saturation from rest to peak exercise (fenestration -4.9 ± 3.8 v. nonfenestration -3 ± 3...

BACKGROUND: Exercise and statins reduce cardiovascular disease (CVD). Exercise capacity may be assessed using cardiopulmonary exercise testing (CPET). Whether statin medication is associated with CPET parameters is unclear. We investigated if statins are related with exercise capacity during CPET in the general population. METHODS: Cross-sectional data of two independent cohorts of the Study of Health in Pomerania (SHIP) were merged (n = 3,500; 50% males). Oxygen consumption (VO2) at peak exercise (VO2peak) and anaerobic threshold (VO2@AT) was assessed during symptom-limited CPET...

BACKGROUND: Cardiopulmonary exercise testing (CPET) is the gold standard in the evaluation of patients with chronic heart failure (CHF). However, this test is relatively expensive, assessment of its results requires experience, and in Poland it is available only in tertiary health care centers. Many heart rate (HR) parameters taken during a standard electrocardiographic (ECG) exercise test also shows prognostic values. Thus, the aim of this study is to compare prognostic values of ventilatory and HR parameters in exercise testing in CHF patients, and to find out if HR parameters can be used instead of ventilatory in the evaluation of a prognosis...

G551D , a mutation of the cystic fibrosis transmembrane conductance regulator (CFTR) gene, results in impaired chloride channel function in cystic fibrosis (CF) with multiple end-organ manifestations. The effect of ivacaftor, a CFTR-potentiator, on exercise capacity in cystic fibrosis (CF) is unknown. Twenty G551D-CF patients were recruited to a single-centre, double-blind, placebo-controlled, 28-day crossover study of ivacaftor. Variables measured included percentage change from baseline (%Δ) of VO2max (maximal oxygen consumption, primary outcome) during cardiopulmonary exercise testing (CPET), relevant other CPET physiological variables, lung function, BMI, sweat chloride, and disease specific health related quality of life (QOL) measures (CFQ-R and Alfred Wellness (AWEscore))...

Cardiopulmonary exercise testing (CPET) in hyperoxia and hypoxia has several applications, stemming from characterization of abnormal physiological response profiles associated with exercise intolerance. As altered oxygenation can impact on the performance of gas-concentration and flow sensors and pulmonary gas exchange algorithms, integrated CPET system function requires validation under these conditions. Also, as oxygenation status can influence peak O2 uptake, care should be taken in the selection of work-rate incrementation rates when CPET performance is to be compared with sea-level...

The six minute walk test (6MWT) is a standardized test that provides information on exercise capacity in patients with COPD. It is considered a submaximal test in opposition to incremental cardiopulmonary exercise tests (CPET) that provide valuable information on all the systems involved in exercise. OBJECTIVES: 1. To compare the perceptive, physiological responses and degree of dynamic hyperinflation during two exercise tests: the 6MWT and the incremental CPET on a treadmill. 2. To evaluate how dyspnea is related to dynamic hyperinflation (DH) and other functional parameters in both tests...

The aim of the current study was to compare 2 equations to predict peak oxygen uptake (V̇O2peak) in obese women, according to their obesity class. 92 maximal cardiopulmonary exercise testing sets (CPET with initial and subsequent increments set to achieve an exercise duration between 8-12 min) were retrospectively analysed. These CPET were divided into 3 groups according to the women body mass indexes (BMI): class 1 (30 kg.m(-2)≤BMI<35 kg.m(-2), n=22), class 2 (35 kg.m(-2)≤BMI<40 kg.m(-2), n=36) or class 3 (BMI≥40 kg...

Cardiopulmonary exercise testing (CPET) has been used for prognosis in idiopathic pulmonary arterial hypertension (IPAH). We explored whether sex differences had an impact on prognostic assessments of CPET in IPAH. Data were retrieved from 21 male and 36 female incident IPAH patients who underwent both right heart catheterization and CPET from 2010 to 2016 at Shanghai Pulmonary Hospital. Cox proportional hazards analysis was used to assess the prognostic value of CPET. The mean duration of follow-up was 22±15 months...

Cardiopulmonary exercise testing (CPET) is useful for the evaluation of patients with suspected or confirmed pulmonary hypertension (PH). End-tidal carbon dioxide pressure (PETCO2) during exercise is reduced with elevated pulmonary artery pressure. However, the utility of ventilatory parameters such as CPET for detecting PH remains unclear. We conducted a review in 155 patients who underwent right heart catheterization and CPET. Fifty-nine patients had PH [mean pulmonary arterial pressure (mPAP) ≥25 mmHg]...

BACKGROUND: The Glittre activities of daily living (ADL) test is supposed to evaluate the functional capacity of COPD patients. The physiological requirements of the test and the time taken to perform it by COPD patients in different disease stages are not well known. The objective of this work was to compare the metabolic, ventilatory, and cardiac requirements and the time taken to carry out the Glittre ADL test by COPD subjects with mild, moderate, and severe disease. METHODS: Spirometry, Medical Research Council questionnaire, cardiopulmonary exercise test, and 2 Glittre ADL tests were evaluated in 62 COPD subjects...

PURPOSE: Arterial hypertension (aHT) is the leading risk factor for morbidity and mortality worldwide. Blood pressure (BP) deviation at rest is well defined and accompanies risk for cardiovascular events and cardiovascular mortality. A growing body of evidence emphasises that an exaggerated blood pressure response (EBPR) in cardiopulmonary exercise testing (CPET) could help to identify seemingly cardiovascular healthy and normotensive subjects, who have an increased risk of developing aHT and cardiovascular events in the future...

Background: Cardiopulmonary exercise testing (CPET) measures peak exertional oxygen consumption ( V˙O2peak ) and that at the anaerobic threshold ( V˙O2 at AT, i.e. the point at which anaerobic metabolism contributes substantially to overall metabolism). Lower values are associated with excess postoperative morbidity and mortality. A reduced haemoglobin concentration ([Hb]) results from a reduction in total haemoglobin mass (tHb-mass) or an increase in plasma volume. Thus, tHb-mass might be a more useful measure of oxygen-carrying capacity and might correlate better with CPET-derived fitness measures in preoperative patients than does circulating [Hb]...

OBJECTIVE: The diagnostic yield of combined cardiopulmonary exercise testing (CPET) and myocardial perfusion imaging (MPI) in patients referred for stress testing has received limited study. METHODS: We evaluated consecutive patients who underwent combined CPET-MPI at a single tertiary referral center between 2011 and 2015. An abnormal CPET was defined as any of the following: reduced oxygen consumption, cardiac output impairment, or pulmonary impairment. Normal MPI was defined as the absence of resting or stress perfusion defect...

BACKGROUND: The need for additional research on symptomatic smokers with normal spirometry has been recently emphasized. Albeit not meeting criteria for Chronic obstructive pulmonary disease (COPD) diagnosis, symptomatic smokers may experience activity limitation, evidence of airway disease, and exacerbations. We, therefore, evaluated whether symptomatic smokers with borderline spirometry (post-bronchodilator FEV1/FVC ratio between 5th to 20th percentile of predicted values) have pulmonary function abnormalities at rest and ventilatory constraints during exercise...

INTRODUCTION: Maximum Voluntary Ventilation (MVV), a surrogate marker of maximum ventilatory capacity, allows for measuring ventilatory reserve during Cardiopulmonary Exercise Stress Testing (CPET) which is necessary to assess ventilatory limitation. MVV can be measured directly during a patient maneuver or indirectly by calculating from FEV1 (FEV1 X 40). We investigated for a potential difference between calculated MVV and measured MVV in pediatric subjects, and which better represents maximum ventilatory capacity during CPET...
