WebLA variables measured by 2D-STE The peak systolic LA strain (LA-Res), peak LA strain just before atrial contraction (LA-Pump) and peak LA strain rate during atrial contraction (LA-SRA ) were lower in the NAFLD group than in the control group (P = 0.007, P = 0.006 and P = 0.018 respectively) (Table 3). WebFor a pulsatile flow, a representative normal carotid artery bifurcation wave form is imposed at the carotid artery (CCA) inlet of the model with mean and peak flow rates 6.0 - 23.8 m/sec. Peak systolic and diastolic pressure are compared with varying cardiac cycle (< 70 and > 70 beats per min).
