Left Ventricular Pressure Strain –Derived Myocardial Work at Rest and during Exercise in Patients with Cardiac Amyloidosis

In a recent paper, Clemmensen et  al.1 have applied left ventricular pressure strain–derived myocardial work (LVMW) indices in a cohort of cardiac amyloidosis (CA) patients and healthy controls, both at rest and during semisupine exercise.1 The authors report that CA patients have significantly lower rest longitudinal strain (LS ) along with lower LVMW and myocardial work efficiency compared with controls. In addition, during exercise, they present a lower improvement of LVMW mainly driven by apical regions and a significantly reduced energy exploitation (based on LS evaluation).
