Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Heart failure with preserved ejection fraction (HFpEF) is a major public health problem that has no proven effective treatment. However, in practice, it's difficult to recognize early stage of HFpEF by resting hemodynamic study and echocardiography because the patients mainly complaint of dyspnea only during exercise but not resting condition. Accordingly, exercise stress test will be helpful to provide more information on pathophysiology, diagnosis, and severity in various cardiovascular diseases such as HFpEF, valvular heart disease, and chronic thromboembolic pulmonary hypertension. Thus, 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. Specifically, this study will 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 for patients with dyspnea on exertion referred to the catheterization lab.
