OBJECTIVE: This study describes results of iCPET from the past, which used submaximal stress and multisensor high-fidelity catheters to exclude heart disease in a unique population of young adults. BACKGROUND: There has been resurgence in comprehensive hemodynamic evaluation of complex cardiovascular patients. Although dynamic assessments during cardiac catheterization have become commonplace, there remains limited information regarding left and right heart hemodynamic changes during supine exercise in young adults...

BACKGROUND: Patients with advanced liver disease may develop portal hypertension that can result in variceal haemorrhage. Beta-blockers reduce portal pressure and minimise haemorrhage risk. These medications may attenuate measures of cardiopulmonary performance, such as the ventilatory threshold and peak oxygen uptake measured via cardiopulmonary exercise testing. AIM: To determine the effect of beta-blockers on cardiopulmonary exercise testing variables in patients with advanced liver disease...

Longitudinal strain (LS) has been shown to be predictive of outcome in hypertrophic cardiomyopathy (HC). Percent predicted peak oxygen uptake (ppVO2), among other cardiopulmonary exercise testing (CPX) metrics, is a strong predictor of prognosis in HC. However, there has been limited investigation into the combination of LS and CPX metrics. This study sought to determine how LS and parameters of exercise performance contribute to prognosis in HC. One hundred and thirty-one consecutive patients with HC who underwent CPX and stress echocardiography were included...

Left-sided coronary revascularization with bilateral internal thoracic artery (BITA) graft is performed usually either with an in situ (double source) or Y-graft configuration (single source). Two hundred fifty-three (mean age, 67.1 ± 9.5 years) patients underwent isolated left-sided coronary revascularization with BITA graft alone at the present authors' institution (2000-2015). Skeletonized BITA grafts were used either in an in situ (n = 199) or Y-graft configuration (n = 54). Forty pairs were identified with the propensity score-matching...

Objective: To test whether women with metabolic syndrome (MS) have impairments in the on- and off-transients during an incremental test and to study whether any of the MS components are independently associated with the observed responses. Research Design and Methods: Thirty-six women aged 35-55 years were divided into a group with MS (MSG, n = 19) and a control group (CG, n = 17). R-R intervals (RRi) and heart rate variability (HRV) were calculated on a beat-to-beat basis and the heart rate (HR) at the on- and off-transient were analyzed during an incremental cardiopulmonary exercise test (CPET)...

BACKGROUND: Patient-reported dyspnea plays a central role in assessing cardiopulmonary disease. There is little evidence, however, that dyspnea correlates with objective exercise capacity measurements. If the correlation is poor, dyspnea as a proxy for objective assessment may be misleading. OBJECTIVE: To compare patient's perception of dyspnea with maximum oxygen uptake (MaxVO2) during cardiopulmonary exercise testing (CPET). METHODS: Fifty patients undergoing CPET for dyspnea evaluation were studied prospectively...

Chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD) are 2 major pulmonary comorbidities of primary lung cancer patients. The COPD patients are at risk for respiratory failure after a major lung resection when lung resection exceeds the patient's pulmonary reserve. It is important to assess a postoperative risk based on the patient's cardiopulmonary function. Cardiac risks are initially evaluated for all the candidates for lung resection, then, ppoFEV1% and ppoDLco% are calculated...

Good quality of life correlates with a good exercise capacity in daily life in patients with tetralogy of Fallot (ToF). Patients after correction of ToF usually develop residual defects such as pulmonary regurgitation or stenosis of variable severity. However, the importance of different hemodynamic parameters and their impact on exercise capacity is unclear. We investigated several hemodynamic parameters measured by cardiovascular magnetic resonance (CMR) and echocardiography and evaluated which parameter has the most pronounced effect on maximal exercise capacity determined by cardiopulmonary exercise testing (CPET)...

INTRODUCTION: The application of expiratory positive airway pressure (EPAP) in patients with COPD during exercise may reduce dynamic hyperinflation, while, on the other hand, it can increase the resistive work of breathing. Therefore, we evaluated the effects of 2 intensities of EPAP during exercise on tolerance, dynamic hyperinflation, and dyspnea in subjects with moderate to very severe COPD. METHODS: We performed a cross-sectional, experimental, 4-visit study...

AIM: to assess effect of interval hypoxic-hyperoxic training (IT) on exercise tolerance and quality of life of patients with ischemic heart disease (IHD) receiving optimal medical therapy, as well as the safety of IHHT use. METHODS: Patients with stable IHD with functional class II and III angina (n=46) were randomized into two groups: IHHT (n=27, 15 treatments in 3 weeks), and IHHT imitation (n=19). Cardiopulmonary stress test was performed to evaluate the following parameters of exercise tolerance: peak oxygen consumption (VO2peak, VO2peak/kg), % of predicted peak oxygen consumption (%VO2 peak) and anaerobic threshold (VO2AT)...

INTRODUCTION: The most widely used instrument to measure perceived exertion or exercise intensity is the Borg's Rating of Perceived Exertion (RPE) Scale. Panic attacks are aversive experiences that may be triggered by bodily sensations such as palpitations, breathlessness or dizziness due to increasing autonomic distress, prior sensitisation to panic and fear conditioning. The consequence is catastrophic interpretation of bodily sensations of arousal in general, which can lead to misinterpretation of exertion or exercise intensity...

Short-term and long-term reproducibility of the cardiopulmonary (CPX) exercise test have been established. Though short and mid-term reproducibility of the walk test has been ascertained, this was not extensively done for the long-term reproducibility. The aim of the study was to examine the long-term reproducibility of distance walked in an allotted time and to check the stability of the relationship between walked distance and exercise peak VO2 (pVO2). METHODS: Forty six subjects (33 men; 57 ± 14 years), referred for functional capacity assessment, were studied twice by CPX and walking test...

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...
