Left atrial strain, especially left atrial reservoir strain (LASr), is an important tool in the assessment of atrial function and diastology. It changes before remodeling becomes detectable on echocardiography and contributes to a better understanding and characterization of diastolic dysfunction and left atrial–left ventricle (LA–LV) uncoupling.– In patients with preserved ejection fraction, LASr values <18% strongly suggest elevated filling pressures., In amyloid cardiomyopathy, the mean values of the atrial strain components are characteristically very reduced compared with individuals without the […]
