Exercise Haemodynamics May Unmask the Diagnosis of Diastolic Dysfunction Among Patients with Pulmonary Hypertension

Abstract

In symptomatic patients with pulmonary hypertension, preserved left ventricular ejection fraction and PAWP ≤15 mmHg, exercise during right heart catheterization may unmask diastolic dysfunction. This is especially true for obese patients and patients with borderline resting PAWP.
