It mainly reflects how much blood fills the ventricles (the main pumping chambers) at the end of filling. Clinicians use Preload to describe volume status and to interpret blood pressure, shortness of breath, and heart failure physiology. It is discussed in everyday cardiology, intensive care, anesthesia, and echocardiography."}
