Abstract
<p><strong>Introduction</strong>: The cardiopulmonary exercise test (CPET) allows the evaluation of peak and sub-maximal tolerance to the effort, giving us relevant information for making clinical decisions. The Cardiorespiratory Optimal Point (COP), calculated as the minimum ratio between ventilation and oxygen consumption and (VE / VO2), may be a good predictor of events and may be influenced by some factors.</p> <p><strong>Objective</strong>: The aim was to characterize the population of the cardiac rehabilitation (CR) appointment who performed CPET, determine predictive factors of the COP, and evaluate the variation of the COP with the CR program.</p> <p><strong>Methods</strong>: Retrospective analysis of CR appointment patients who underwent CEPT between 2014 and 2017 in a single center. We evaluated clinical, laboratory and echocardiographic characteristics and determined predictors of COP value.</p> <p><strong>Results</strong>: 207P (83.6% men) were included, with a mean age of 57 years. The mean COP was 23.6 +-5.8 (IC [24.06-25.66]). The majority (96.6%) had a cardiovascular disease or risk factor (diabetes in 24.6%, hypertension in 55.1%, dyslipidemia in 55.1%, excess weight or obesity in 75.4%, with mean body mass index of 27.3, family history in 16.4%, acute myocardial infarction (AMI) in 19.3%, smoking in 44.4% and other diseases in 51.2%). 99% were medicated (91.3% acetylsalicylic acid, 65.2% clopidogrel, 23.7% ticagrelor, 92.8% beta-blocker, 91.3% ACEI / ARB, 90.3% statin). The majority (87.9%) was referred for CR with isquemic cardiopathy (AMI or stable or unstable coronary disease) , 9.2% with heart failure (HF) and 9.2% with valvulopathy. The predictors of a highest value of COP were higher age (CC=0.269, p<0.0001), female sex (p = 0.001), heart failure (p = 0.017), lower ejection fraction (CC = -0.124, p = 0.011), lower haemoglobin (CC = -0.170, p <0.0001), higher BNP (CC = 0.233, p <0.0001) and higher erythrocyte sedimentation rate (CC = 0.171, p = 0.004). Of these, independent predictors of higher COP were age (p <0.0001), lower haemoglobin (p = 0.001) and higher BNP (p <0.0001).</p> <p><strong>Conclusion</strong>: The COP value is related to multiple factors, of which the age, the BNP value and the haemoglobin value are independent factors.</p>
