Heart failure can result from many types of heart disease, notes Mayo Clinic. Heart failure occurs when the pumping action of the heart is no longer able to supply enough blood to meet the oxygen needs of all the tissues of the body.

Heart attacks can happen when part of the heart muscle does not receive the oxygen it needs to function because of a clot in the blood vessels of the heart, adds the National Heart, Lung, and Blood Institute. Strokes occur when blood vessels of the brain are narrowed and blocked, which results in insufficient blood to the brain, reports Mayo Clinic.

An aneurysm is the bulging of an artery caused by weakened blood vessel walls. When aneurysms rupture, this can result in massive blood loss, explains MedlinePlus. Sudden cardiac arrest occurs when there is abrupt loss of heart functioning, respiration and consciousness. If medical attention is not sought immediately, this condition is likely to be fatal, according to Mayo Clinic.
