Heart Attack/Failure: Heart attack is referring to damage to the heart muscle due to lack of blood flow. Heart failure means the heart muscle doesn't work right. Heart failure can certainly occur as a consequence of damage from a heart attack. Heart failure can also occur because of damage from a viral illness, long-term damage from high blood pressure, and other reasons too lengthy to go into here.

Acute vs chronic: A heart attack [myocardial infarction (MI)] is the death of a portion of the heart muscle that occurs when the artery supplying blood closes. It happens iin minutes to hours. Heart failure is a chronic condition where the heart cannot pump enough blood for the body due to weakness from prior MIs valve disease, chemotherapy or viral infection and fluid backs up into the lungs due to failing pump.
