BACKGROUND: Pulmonary arterial hypertension (PAH) is a rare disease characterised by a severe impairment of functional status and quality of life (QoL). Use of rehabilitative programmes may help to improve outcomes. The aim of this pre/post test case series was to evaluate the impact of a training program, including sessions of aerobic and resistance exercise, inspiratory muscle reinforcement, slow breathing, relaxation, and psychological support, on functional outcomes. METHODS: Fifteen patients affected by PAH, in World Health Organization (WHO) Functional Class (FC) II or III and in stable clinical condition, were included in a 4-week cardiorespiratory training programme conducted in outpatient service...

Vipa Bernhardt, Tony G Babb
The purpose of cardiopulmonary exercise testing (CPET) in the obese person, as in any cardiopulmonary exercise test, is to determine the patient's exercise tolerance, and to help identify and/or distinguish between the various physiological factors that could contribute to exercise intolerance. Unexplained dyspnoea on exertion is a common reason for CPET, but it is an extremely complex symptom to explain. Sometimes obesity is the simple answer by elimination of other possibilities. Thus, distinguishing among multiple clinical causes for exertional dyspnoea depends on the ability to eliminate possibilities while recognising response patterns that are unique to the obese patient...

BACKGROUND: Exercise testing is part of the regular assessment of patients with cystic fibrosis (CF). We aimed to evaluate (1) the convergent validity of the 1-min sit-to-stand (STS) test in CF by investigating its relationships with peak oxygen uptake (peak V̇O2 ), quadriceps strength, and quality of life and (2) to compare these associations with those of the 6-min walk test (6MWT). METHODS: Twenty-five adults with CF (FEV1 = 59 ± 24%) performed the STS test, the 6MWT, quadriceps strength assessment, and cardiopulmonary exercise test (CPET)...

The incremental cardiopulmonary exercise test (CPET) is an increasingly used diagnostic method that serves to evaluate patients with chief complaint of dyspnea during exercise. Performing maximal symptom-limited CPET can show if the tested subject has a reduced exercise capacity and give clues to the mechanism of such exercise capacity reduction, cardiac, pulmonary, or pulmonary vascular source. In this review, it is suggested that the evaluation of the complex results of CPET should be performed by first determining if myocardial/circulatory insufficiency is present and second if there is gas exchange abnormality...

Increasing habitual exercise has been associated with improved cardiopulmonary exercise testing (CPET) performance, specifically maximal oxygen consumption in children with operatively corrected congenital heart disease. This has not been studied in children following Fontan palliation, a population in whom CPET performance is dramatically diminished. A single-center cross-sectional study with prospective and retrospective data collection was performed that assessed habitual exercise preceding a clinically indicated CPET in children and adolescents with Fontan palliation, transposition of the great arteries following arterial switch operation (TGA), and normal cardiac anatomy without prior operation...

Improvements in the management of patients undergoing Liver Transplantation (LT) have resulted in a significant increase in survival over recent years. Cardiac disease is now the leading cause of early mortality and the stress of major surgery, haemodynamic shifts, the possibility of haemorrhage or reperfusion syndrome require the recipient to have good baseline cardiac function. The prevalence of coronary artery disease (CAD) is increasing in liver transplant candidates, especially in those with Non-Alcohol related Fatty Liver Disease (NAFLD)...

BACKGROUND: Symptomatic non-obstructive coronary artery disease is a growing clinical dilemma for which contemporary testing is proving to be of limited clinical utility. New methods are needed to identify cardiac dysfunction. METHODS AND RESULTS: This is a prospective observational cohort study conducted from December 2013 to August 2015 in two outpatient cardiology clinics (symptomatic cohort) and 24 outpatient practices throughout the US (healthy cohort) with centralized methodology and monitoring to compare heart-rate responses during cardiopulmonary exercise testing (CPET)...

Cardiopulmonary exercise testing (CPET) is a specialized subtype of exercise testing that provides a more accurate and objective measure of cardiorespiratory fitness (CRF). CPET relies on measurement of ventilatory gases during exercise, i.e., a non-invasive procedure that involves the acquisition of expired ventilation and concentrations of oxygen (O2) and carbon dioxide (CO2) during progressive exercise. The non-invasive measurement of ventilation and expired gases permits the most accurate and reproducible quantification of CRF, a grading of the etiology and severity of impairment, and an objective assessment of the response to an intervention...

Exercise periodic breathing (EPB) is associated with exercise intolerance and poor prognosis in patients with heart failure (HF). However, EPB detection during cardiopulmonary exercise test (CPET) is difficult. The present study investigated the use of a wireless monitoring device to record the EPB during CPET and proposed quantization parameter estimates for the EPB. A total of 445 patients with HF were enrolled and underwent exercise tests. The ventilation data from the wearable device were compared with the data obtained during the CPET and were analyzed based on professional opinion and on 2 automated programs (decision tree [DT] and oscillatory pattern methods)...

BACKGROUND: Depressed heart rate variability (HRV) is usually considered a negative long-term prognostic factor after acute myocardial infarction. Anyway, most of the supporting research was conducted before the era of immediate reperfusion by percutaneous coronary intervention (PCI). Main aim of this study was to evaluate if HRV still retains prognostic significance in our era of immediate PCI. METHODS AND RESULTS: Two weeks after STEMI treated by primary PCI, time-domain HRV was assessed from 24-h Holter recordings in 186 patients: markedly depressed HRV (SDNN <70ms or <50ms) was present in 16% and in 5% of cases, respectively; patients with left ventricle ejection fraction (LVEF) <40% presented more often SDNN values in the lowest quartile...

Functional capacity has been shown to be a major determinant of surgical outcome since it is related to postoperative complications, activity and daily function, level of independence and quality of life. Anesthesiologists as "perioperative physicians", can identify those scoring systems that assess functional capacity, whether from the basic physical history and walk test to the most complex such as cardiopulmonary exercise testing (CPET), and formulate intraoperative and postoperative interventions (rehabilitation) to minimize the impact of surgery on the recovery process...

BACKGROUND: Maximal exercise capacity after heart transplantion (HTx) is reduced to the 50-70% level of healthy controls when assessed by cardiopulmonary exercise testing (CPET) despite of normal left ventricular function of the donor heart. This study investigates the role of donor heart β1 and β2- adrenergic receptor (AR) polymorphisms for maximal exercise capacity after orthotopic HTx. METHODS: CPET measured peak VO2 as outcome parameter for maximal exercise in HTx recipients ≥9 months and ≤4 years post-transplant (n = 41; mean peak VO2: 57±15% of predicted value)...

BACKGROUND: Cardiopulmonary exercise testing (CPET) can identify patients at risk of adverse post-operative outcomes following major abdominal surgery including bariatric surgery. Scoring systems that also aim to predict post-operative outcome in this group include the validated obesity surgery mortality risk score (OSMRS). This study aims to investigate if CPET has additive value to other scoring systems in predicting post-operative outcomes following bariatric surgery. METHODS: Data was collected retrospectively on 398 patients who underwent CPET between October 2008 and April 2013...

BACKGROUND: Common tests for evaluating gas exchange impairment have different strengths and weaknesses. Alveolar-to-arterial oxygen pressure difference (AaDO2) at peak exercise is a sensitive indicator but it cannot be measured repeatedly. Diffusing capacity of the lung for carbon monoxide (DLco) is measured at rest and may be too insensitive to predict the effects of exercise on gas exchange impairment. Oxygen desaturation during a 6-minute walk test (∆SpO2-6MWT) can be measured repeatedly, but its value in sarcoidosis is unknown...
