First of all, if you or a loved one have been told that you have heart failure, don’t panic. Your doctor did not mean that your heart has stopped working completely and there is nothing he or you can do about it. It means that your heart is weaker and pumping with less power than normal. The pressure in your heart has increased and your heart is not pumping all the oxygen and nutrients your body needs. Your body depends on your heart to pump oxygen and nutrient-rich blood to the cells in your body. Your cells must receive proper nourishment for your body to function normally. But with heart failure, your heart is weak and it can’t supply enough oxygen and nutrients to your blood.
