 Systolic function will be measured as an improvement in average longitudinal peak systolic strain rate SR and longitudinal end systolic strain S assessed at the base, mid wall and apex of the IVS, lateral, inferior and anterior wall on cardiac TDI. Improvement in diastolic function will be measured by early peak E and late peak A, trans-mitral flow and annulus motion, isovolumetric relaxation time IVRT and deceleration time DT on transthoracic echocardiogram.
