Heart Attack Warning Signs Some heart attacks are sudden and intense — the movie heart attack, where no one doubts what s happening. But most heart attacks start slowly, with mild pain or discomfort. Often people affected aren t sure what s wrong and wait too long before getting help. Here are signs that can mean a heart attack is happening: Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain. Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach. Shortness of breath with or without chest discomfort. Other signs may include breaking out in a cold sweat, nausea or lightheadedness. As with men, women s most common heart attack symptom is chest pain or discomfort. But women are somewhat more likely than men to experience some of the other common symptoms, particularly shortness of breath, nausea/vomiting, and back or jaw pain. Learn the signs, but remember this: Even if you re not sure it s a heart attack, have it checked out (tell a doctor about your symptoms). Minutes matter! Fast action can save lives — maybe your own. Don’t wait more than five minutes to call 9-1-1. Yes, it is possible to have one in your 30 s but usually a pre-existing condition exists and/or a family history of heart disease. If you are having chest pain you should make sure you do regular breast exams at home and discuss your concerns with your doctor.
