subject: Causes Of Heart Failure [print this page] A past heart attack will have a very negative and damaging effect on your heart, which means that your heart's ability to pump blood will be greatly diminished. Usually, when a person experiences a heart attack, the heart will not be able to receive less oxygen and nutrients, thereby damaging the muscle tissue of the heart. This part that is damaged basically dies, thereby forcing the heart to try and compensate for the loss, making it harder for the heart to maintain its function for a long time.
