Preload and afterload

Topic: Anatomy & physiology

Preload is the stretch of ventricular muscle fibers at the end of diastole, set mainly by venous return. Afterload is the resistance the ventricle must overcome to eject blood, influenced by systemic vascular resistance and blood pressure. In heart failure, diuretics reduce preload and vasodilators reduce afterload, easing the work of the heart.
