FIGURE 1. Pericardial and Atrial Size Interaction Across the Spectrum of AF Risk in HFpEF.

FIGURE 1

(A, B) Increasing total heart volume by both echocardiography and chest radiography was driven by atrial enlargement with increasing atrial fibrillation (AF) burden in heart failure with preserved ejection fraction (HFpEF). (C to F) Patients with greater AF burden displayed increased pericardial restraint with a higher exertional right atrial pressure (RAP), RAP/pulmonary capillary wedge pressure (PCWP) ratio, and lower left ventricular (LV) transmural pressure and enhanced diastolic ventricular interaction in the permanent AF HFpEF group. Par = paroxysmal; Perm = permanent.
