Abstract: The article presents the study which examines the ability of cardiopulmonary exercise testing (CPX) variables to reflect resting hemodynamics in patients with nonobstructive hypertrophic cardiomyopathy (NHCM). Researchers performed CPX and right heart catheterization on 83 subjects with NHCM and compared the peak oxygen consumption and minute ventilation/carbon dioxide ration at peak exercise to resting hemodynamics. Results showed that CPX can accurately identify abnormal resting hemodynamics in patients with NHCM.
