Cardiac contractility (force and velocity of contraction), ventricular performance, and myocardial oxygen requirements are determined by Preload, Afterload, Substrate availability (eg, oxygen, fatty acids, glucose), Heart rate and rhythm and Amount of viable myocardium. #congestive #heart #failure Professor Armen Astvatsatryan, MD, PhD, ScD, FESC.
