About This Trial
The purpose of this study is to evaluate whether pulmonary blood volume (PBV) derived from contrast echocardiography can serve as a non-invasive surrogate for invasive pulmonary artery wedge pressure (PAWP) during exercise. Also, to compare changes in PBV with exercise in patients with and without heart failure and pulmonary vascular disease.
