Heart failure is not a disease but a syndrome, a cluster of signs and symptoms caused by the impairment of the heart's function as a pump to support the circulatory system, at rest or during exercise. It develops when the heart fails to properly fill up with blood during diastole leading to an increase in intracardiac pressures or in ejecting it during systole, thereby reducing cardiac output to the rest of the body. Filling dysfunction and high intracardiac pressure may result in the buildup of fluid in the veins and tissues. This manifests as water retention and swelling due to the buildup of liquid<unk> , collectively referred to as congestion. Impaired ejection can cause inadequate perfusion of the body tissues with blood leading to ischemia.
