What is heart failure?

Heart failure is a condition in which your heart is unable to pump enough blood around your body because of damage to the heart tissue. This can be due to heart attacks leading to scarring, high blood pressure and faulty heart valves. It can cause blood to dam up or congest behind the heart, causing fluid to collect in your lungs or other body tissue.
