Wedge Pressure Rather Than Left Ventricular End-Diastolic Pressure Predicts Outcome in Heart Failure With Preserved Ejection Fraction

This study sought to compare the prognostic power of left ventricular end-diastolic pressure (LVEDP) and pulmonary arterial wedge pressure (PAWP) in heart failure with preserved ejection fraction (HFpEF).It is broadly accepted that direct measurement of LVEDP in HFpEF more robustly reflects left ventricular hemodynamics than PAWP.A total of 173 consecutive HFpEF patients were prospectively enrolled. Of these, 152 patients fulfilled registry...
