Heart Attack Signs and Symptoms The descriptions of heart attacks in the popular media are deceptive: Chest pain is not the only sign of a heart attack. There are a wide variety of heart attack symptoms. Experiencing any of these discomforts might mean your heart and life may be in immediate danger: 1 Upper abdominal pain or upper back pain, especially prevalent in women 2 Shortness of breath 3 Dizziness 4 Left shoulder pain or numbness; an ache down the left arm or into the jaw 5 Chest heaviness, tightness, squeezing, burning, pressure or discomfort 6 Palpitations of the heart (beating fast or irregularly) 7 Tight throat or a lump in the throat 8 Cold sweat 9 Nausea 10 Sense of impending doom 11 Weakness. Be especially wary if any of these discomforts begin in a subtle manner but intensify over several minutes. It is a bad sign if your pain or discomfort is NOT worsened by deep breaths, pressing on your chest or movement of the body area where the discomfort is taking place. In all of those cases, you should seek medical help immediately.
