This study aimed to investigate the validity of the oxygen uptake efficiency slope as an objective and submaximal indicator of cardiorespiratory fitness in elderly patients scheduled for major colorectal surgery. Patients ≥ 60 years of age, with a metabolic equivalent score using the Veterans Activity Questionnaire ≤ 7 and scheduled for major colorectal surgery participated in a pre-operative cardiopulmonary exercise test. The oxygen uptake efficiency slope was calculated up to different exercise intensities, using 100%, 90% and 80% of the exercise data...

Debate on the proper timing of pulmonary valve replacement (PVR) after repair of tetralogy of Fallot is still continuing. We aim to clarify how the different components of right ventricle (RV) changed with relieved volume overload in the remodeling process after pulmonary valve replacement and gain a clear idea of the relationship between different right ventricle components function and exercise capacity after PVR in these patients. The medical records and results of cardiac magnetic resonance imaging and cardiopulmonary exercise testing of 25 consecutive eligible patients were reviewed...

OBJECTIVES: The aim of this study was to assess the relationship between right ventricular (RV) function during pre-load augmentation and exercise tolerance. BACKGROUND: Peak oxygen uptake (VO2) is a strong predictor of mortality in chronic heart failure. Cardiac function during pre-load augmentation is an important part of the phenomenon in the evaluation of exercise capacity. METHODS: We prospectively performed echocardiographic studies in 68 chronic heart failure patients with cardiopulmonary exercise testing (mean age 60 ± 12 years; 69% male)...

Rehabilitation in patients with advanced cardiac and pulmonary disease has been shown to increase survival and improve quality of life, among many other benefits. Exercise training is the fundamental ingredient in these rehabilitation programs. However, determining the amount of exercise is not straightforward or uniform. Most rehabilitation and training programs fix the time of exercise and set the exercise intensity to the goals of the rehabilitation program and the exercise-related hurdles of the individual...

High intensity physical exercise has previously been found to lead to a decline in cognitive performance of adults. The aim of this study was to determine the effects of maximal intensity exercise on cognitive performance of children. Using a repeated-measures design, 20 children and adolescents aged 8-17 years completed a battery of tests measuring memory and attention. Forward and Backward Digit Span tests, the Rey Auditory-Verbal Learning Test (RAVLT) and the Digit Symbol Substitution Test (DSST) were performed at baseline, immediately after, and one hour after a maximal cardiopulmonary exercise test...

We aimed to develop an equation to predict peak VO2 in obese subjects undergoing CPET. In addition, we evaluated and compared three published equations. We randomized 346 obese subjects undergoing CPET into a group for developing the equation (n = 272) and a group for cross-validation (n = 74), compared through the Bland and Altman method. Height, sex and age were responsible for 85·5% of total variability of the peak VO2. Additional 1% and 0·7% of the variability were, respectively, explained by physical inactivity and diabetes...

Pulmonary arterial hypertension (PAH) is a feared complication of systemic sclerosis. In this prospective cohort study, we monitored the changes in resting and exercise pulmonary haemodynamics of scleroderma patients without initial PAH over a mean follow-up period of ∼4 years.All patients underwent exercise echocardiography and cardiopulmonary exercise testing at baseline and follow-up. A subgroup underwent exercise right heart catheter (RHC) investigations. The primary end-point was the echocardiographic systolic pulmonary arterial pressure at 50 W exercise (sPAP50)...

The approach to managing asymptomatic or questionably symptomatic patients for aortic stenosis is difficult. We aimed to determine whether cardiopulmonary exercise testing (CPET) is prognostically useful in such patients. Patients judged asymptomatic or questionably symptomatic for aortic stenosis with aortic valve area index <0.6 cm(2)/m(2) and left ventricular ejection fraction ≥0.50 were managed conservatively provided they had either (group 1) normal peak oxygen consumption and peak oxygen pulse (>83% and >95% of the predicted values, respectively) or (group 2) subnormal peak oxygen consumption or peak oxygen pulse but with CPET data pointing to pathologies other than hemodynamic compromise from aortic stenosis...

BACKGROUND: Despite the low early mortality of Fontan procedures, Fontan patients are prone to various cardiac and extra-cardiac complications in the long term. This may influence patient perception of their health and outcome. The aim of the study was to assess the relationship of multi-organ complications and physical efficiency with self-reported health-related quality of life (QOL) in adult Fontan patients. METHODS: Quality of life was assessed with the Short Form-36 questionnaire...

BACKGROUND: Revascularization appears to be beneficial only in patients with high levels of ischemia. This study examined the utility of gas analysis during the recovery phase of cardiopulmonary exercise testing (CPET) in predicting coronary artery disease (CAD) severity and prognosis. METHODS: 40 Caucasian patients (21.2% females), mean age 63.5±7.6 with significant coronary artery lesions (≥50%) were studied. Within two months of coronary angiography, CPET on a treadmill (TM) and recumbent ergometer (RE) were performed on two visits 2-4days apart; subjects were subsequently followed 32±10months...

OBJECTIVE: Many patients with congenital heart disease (CHD) require surgery to ensure survival into adulthood. But history of previous thoracotomies is associated with respiratory muscle weakness, impairments in chest wall compliance, and moderately to severely impaired lung function. This study evaluated the impact of thoracotomies on functional outcome in patients with CHD. PATIENTS AND METHODS: In total 1372 adolescents and adults with CHD (32.4±11.5 years, 624 female), who underwent spirometry and cardiopulmonary exercise testing in our institution from January 2010 to August 2015, were analyzed...
