- The broad objective of this proposal is to characterize the dynamic changes in cardiopulmonary mechanics during stress in patients with exertional dyspnea, establishing a comprehensive multimodality diagnostic approach to the evaluation of exercise intolerance.
- The specific objective is to prospectively compare established and novel parameters derived from echocardiography and CPX with simultaneous, gold standard invasive measures of cardiovascular hemodynamics at rest and with exercise stress to define the role of noninvasive testing in the diagnostic workup.
- The primary hypothesis is that combined ExE and CPX can noninvasively identify HFpEF.
