The effect of cardiac resynchronization therapy on left ventricular diastolic function assessed with speckle‐tracking echocardiography

Changes in left ventricular (LV) diastolic function after cardiac resynchronization therapy (CRT) in relation to LV reverse remodelling and heart failure aetiology have not been extensively characterized. The aims of the study were to evaluate changes in LV diastolic function with speckle‐tracking echocardiography in relation to: (i) cardiac resynchronization therapy response (LV remodelling) and (ii) heart failure aetiology.
