Key result
Patients with heart failure with preserved ejection fraction had significantly greater interatrial dyssynchrony compared to non-heart failure subjects (72.7 vs 28 ms, P<0.001).
Why the study?
Is interatrial dyssynchrony increased in patients with HFPEF compared to non-HF subjects presenting with shortness of breath?

Interatrial dyssynchrony assessment should not yet change dyspnea evaluation; leaves open its mechanistic or therapeutic role in HFpEF.

Sanchís et al. (2015) conducted a cross-sectional in Heart failure with preserved ejection fraction (HFPEF) (n=66). Heart failure with preserved ejection fraction (HFPEF) vs. Non-heart failure subjects was evaluated on Interatrial dyssynchrony (interatrial time difference in ms) (p=< 0.001). Patients with heart failure with preserved ejection fraction had significantly greater interatrial dyssynchrony compared to non-heart failure subjects (72.7 vs 28 ms, P<0.001).
