Validation of a cardiopulmonary exercise test score in heart failure.
BACKGROUND Cardiopulmonary exercise test (CPX) responses are strong predictors of outcomes in patients with heart failure. We recently developed a CPX score that integrated the additive prognostic information from CPX. The purpose of this study was to validate the score in a larger, independent sample of patients. METHODS AND RESULTS A total of 2625 patients with heart failure underwent CPX a...
متن کاملHeart Rate Dynamics During A Treadmill Cardiopulmonary Exercise Test in Optimized Beta-Blocked Heart Failure Patients
BACKGROUND Calculating the maximum heart rate for age is one method to characterize the maximum effort of an individual. Although this method is commonly used, little is known about heart rate dynamics in optimized beta-blocked heart failure patients. AIM The aim of this study was to evaluate heart rate dynamics (basal, peak and % heart rate increase) in optimized beta-blocked heart failure p...
متن کاملCardiopulmonary Exercise Testing in Heart Failure.
Exercise intolerance, indicated by dyspnea and fatigue during exertion, is a cardinal manifestation of heart failure (HF). Cardiopulmonary exercise testing (CPET) precisely defines maximum exercise capacity through measurement of peak oxygen uptake (VO2). Peak VO2 values have a critical role in informing patient selection for advanced HF interventions such as heart transplantation and ventricul...
متن کاملA cardiopulmonary exercise testing score for predicting outcomes in patients with heart failure.
OBJECTIVE The aim of this study is to evaluate the predictive accuracy of a cardiopulmonary exercise test (CPX) score. BACKGROUND Cardiopulmonary exercise test responses, including peak VO(2), markers of ventilatory inefficiency (eg, the VE/VCO(2) slope and oxygen uptake efficiency slope [OUES]), and hemodynamic responses, such as heart rate recovery (HRR) and chronotropic incompetence (CRI) ...
متن کاملCardiopulmonary Exercise Testing in Patients With Heart Failure
A recent issue of the Journal included two articles (1,2) involving cardiopulmonary exercise testing in patients with heart failure. Despite the clinical consequences of this test, there is no standardization of the compilation of results from the raw data. Interestingly, there is a great deal of literature involving the determination of ventilatory threshold but little standardization within o...
