Summary

Invasive diagnosis of heart failure with preserved ejection fraction (HFpEF) in patients with unexplained dyspnea NYHA II-III compared to other diagnostic tools

Conditions

Interventions

DIAGNOSTIC_TEST

Invasive hemodynamics of left ventricle via conductance catheter at rest, with exercise and with temporary vena cava occlusion

Invasive hemodynamics of left ventricle will be done by the conductance method. Left ventricular stiffness constant will be obtained by temporary vena cava occlusion. Right heart catherization will be done by pulmonary artery catherization and cardiac output will be estimated by thermodilution and Fick´s method.
