Angina is a symptom, whereas a heart attack is a health condition. Angina is pain experienced by people when there is a decrease in oxygen supply to the heart. A heart attack is the consequent damage to the heart. Decreased oxygen supply occurs due to blocked flow of blood to the heart, which further causes the damage. With no blood, tissues lose oxygen and are unable to function normally. This condition induces angina pain. The more time that passes with no oxygen to the tissues, the greater the damage that occurs to the heart muscle resulting in a heart attack.
An angina attack comes with a set of symptoms very similar to a heart attack. It is not always easy for a person to differentiate between the two. If you experience any pain around your heart, consult your doctor immediately. Do not try to differentiate between angina and heart attack or self-diagnose your condition. This may cause loss of crucial treatment time and endanger your life.
