Signs & Symptoms: Heart Failure

The symptoms may get worse as the buildup of plaque continues to narrow the coronary arteries. Chest pain or discomfort that does not go away or happens more often or while you are resting might be a sign of a heart attack. If you do not know whether your chest pain is angina or a heart attack, call 9-1-1 right away. All chest pain should be checked by a doctor.
