01/01/2009 - "The use of CPET in the management of chronic heart failure patients is increasing, with the understanding that resting pulmonary and cardiac function testing cannot reliably predict exercise performance and functional capacity and that, furthermore, overall health status and prognosis are better predicted by indices of exercise tolerance than by resting measurements."
02/01/2014 - "The cardiopulmonary exercise test (CPET) is considered to be the gold standard to evaluate functional capacity (FC) in patients with heart failure. "
02/01/2012 - "The study aims were to validate the cardiopulmonary exercise testing (CPET) parameters recommended by the European Society of Cardiology 2008 Guidelines for risk assessment in heart failure (HF) (ESC-predictors) and to verify the predictive role of 11 supplementary CPET (S-predictors) parameters. "
10/01/2009 - "The aim of the study is to compare the cardiorespiratory response during the 6-min walk test (6MWT) with a symptom-limited cardiopulmonary exercise test (CPET) in patients with varying degrees of heart failure. "
10/01/2007 - "Studies demonstrating prognostic value of excessive exercise ventilation in chronic heart failure (CHF) have focused on data derived from the whole cardiopulmonary exercise test (CPET). "

03/01/2012 - "The aim of this study was to identify CPET measures that might be helpful in predicting the vital capacity and diffusion capacity outcomes of patients with thoracic sarcoidosis. "
01/01/2014 - "OUES assessed in CPET may be helpful in identifying patient with cardiac involvement of sarcoidosis. "
05/01/2014 - "The aim of this study was to compare the modified shuttle walk test (MSWT) to cardiopulmonary exercise test (CPET) as a measure of peak exercise capacity in sarcoidosis. "
05/01/2014 - "Thirty-three (17 male, mean age 48 years) patients with sarcoidosis completed a standardized exponential exercise protocol cycle ergometer CPET and a single corridor MSWT in random order. "
01/01/2014 - "Patient selection for CMR may be assisted by CPET findings in patients with sarcoidosis."

09/01/2009 - "Cardiopulmonary exercise testing (CPET) using gas exchange techniques provides a global assessment of the exercise response, and it is the accepted gold-standard for the evaluation of unexplained dyspnea. "
04/01/2015 - "Cardiopulmonary exercise testing (CPET) measures physiologic parameters during exercise which can enable accurate identification of the cause of dyspnea. "
10/01/2014 - "Cardiopulmonary exercise testing (CPET) is the most comprehensive investigation for understanding the mechanisms responsible for dyspnea in patients with chronic respiratory disease. "
05/01/2014 - "Distance walked (m) was compared between the first and second ISWTs; greatest distance walked was correlated with peak load and Vo2peak obtained from CPET, steps per day, and dyspnea evaluated by the Medical Research Council (MRC) scale; and desaturation was compared between CPET and the ISWT. "
12/01/2013 - "Cardiopulmonary exercise testing (CPET) is the examination of choice to understand mechanisms responsible for dyspnea in patients without significant medical history. "

09/30/2013 - "The ST/HR hysteresis is superior to CPET-derived parameters for detecting exercise-induced myocardial ischemia in patients with equivocal ECG exercise test results."
09/30/2013 - "Because ST segment depression has limited diagnostic performance at exercise electrocardiography (ECG), ST segment depression/heart rate (ST/HR) hysteresis and cardiopulmonary exercise test (CPET)-derived parameters have been proposed as alternatives to diagnose exercise-induced myocardial ischemia. "
10/01/2010 - "This case-based concept report describes CPET abnormalities in an asymptomatic at-risk man with suspected early-stage ischemic heart disease. "
10/01/2010 - "Evidence demonstrating the potential value of noninvasive cardiopulmonary exercise testing (CPET) to accurately detect exercise-induced myocardial ischemia is emerging. "
03/01/2009 - "In conclusion, adding CPET with gas exchange measurements is likely to be of value in diagnosing and quantifying both overt and occult myocardial ischemia and its reversibility with treatment."

06/01/2012 - "We performed a maximal cardiopulmonary exercise test (CPET) with ramp protocol at sea level to evaluate patients' performance and two moderate intensity constant workload CPETs (50% of peak workload) at sea level (normoxia) and simulated altitude (hypoxia). "
03/22/2006 - "Based on gas-exchange findings as the initial diagnostic tool, the high ventilatory equivalents for CO2, low sustained end-tidal PCO2, hypoxemia, and central cardiovascular dysfunction during cardiopulmonary exercise testing (CPET) suggested that each had significant pulmonary vasculopathy with right-to-left shunting. "
12/01/2014 - "Subsequently, spirometry and CPET were performed to examine parameters of exercise-induced hypoxemia ([PaO2 slope, mmHg/L · min(-1)] = Decrease in PaO2/ΔV˙ O2 (Difference in ΔV˙ O2 between at rest and at peak exercise)), progression of acidosis ([ΔpH/ΔV˙ O2,/L · min(-1)] = Decrease in pH/ΔV˙ O2), and sympathetic overactivity ([Δnorepinephrine (NE)/ΔV˙ O2, ng/mL/L · min(-1)] = Increase in NE/ΔV˙ O2). "
12/01/2014 - "We recently identified three life-threatening pathophysiological conditions during cardiopulmonary exercise testing (CPET): (1) exercise-induced hypoxemia, (2) sympathetic overactivity, and (3) progressive respiratory acidosis at low-intensity exercise. "
06/01/2012 - "Ten patients, who lowered oxygen kinetics in hypoxia, had greater HR increase during maximal CPET suggesting lower functional beta-blockade. "
