In addition, significant correlations were observed between VP and relative wall thickness (r: 0.45 p: 0.03),VE/VCO2 intercept and Mitral E/e’ ratio (r: 0.70 p: 0.003) in the CHF group. Significant correlations were found between indexed left ventricle mass and RPP (r: − 0.47; p: 0.02) and relative VO2 and right ventricle diameter (r: − 0.62; p: 0.001) in the CHF+COPD group.Conclusion: Compared to a diagnosis of CHF alone, a combined diagnosis of CHF+COPD induced further impairments in cardiorespiratory fitness. Moreover, echocardiographic measures of cardiac function are related to cardiopulmonary exercise performance and therefore appear to be an important therapeutic target when attempting to improve exercise performance and functional capacity.Keywords: heart failure, chronic obstructive pulmonary disease, eccentric hypertrophy, ventricular dysfunction, cardiopulmonary exercise testing, echocardiography |
