Impact of Left Atrial Phasic Function in Heart Failure with Preserved Ejection Fraction: Insights From Cardiac Magnetic Resonance Feature Tracking.

Impaired left atrial (LA) function is a hallmark of heart failure with preserved ejection fraction (HFpEF) ([1][1]). However, how the various phases of LA function (reservoir, conduit, and booster pump function) ([Figure 1][2]) contribute to hemodynamic changes and cardiovascular outcomes in HFpEF
