Exercise Hemodynamics Enhance Diagnosis of Early Heart Failure With Preserved Ejection Fraction
Why the study?
Does exercise hemodynamics improve the diagnosis of early HFpEF in euvolemic patients with exertional dyspnea, normal BNP, and normal resting cardiac filling pressures?
Population
Euvolemic patients with exertional dyspnea, normal brain natriuretic peptide, and normal cardiac filling…

Implication
May support exercise hemodynamics testing in select unexplained dyspnea cases; leaves open prospective validation before practice change.
Structured PICO
Does exercise hemodynamics improve the diagnosis of early HFpEF in euvolemic patients with exertional dyspnea, normal BNP, and normal resting cardiac filling pressures?
P
Population
Euvolemic patients with exertional dyspnea, normal brain natriuretic peptide, and normal cardiac filling pressures at rest
I
Intervention
Exercise hemodynamics
O
Outcome
Diagnosis of early heart failure with preserved ejection fraction (HFpEF)
Exercise hemodynamics may enable earlier and more accurate diagnosis of HFpEF in patients with unexplained exertional dyspnea and normal resting hemodynamics.
