For both women and men, the most common heart attack symptom is pain or discomfort in the center of the chest. The pain or discomfort can be mild or strong. It can last more than a few minutes, or it can go away and come back.

The more heart attack symptoms that you have, the more likely it is that you are having a heart attack.¹ Also, if you've already had a heart attack, your symptoms may not be the same for another one. Even if you are not totally sure you are having a heart attack, call 911 right away.

Women are more likely than men to have a different symptom of heart attack than chest pain or discomfort. These symptoms include:

• Pain in the back, neck, jaw, or throat
• Indigestion
• Heartburn
• Nausea (feeling sick to the stomach)
• Vomiting
• Extreme fatigue (tiredness)
• Problems breathing (shortness of breath)

Women are more likely than men to have heart attacks that do not show obvious symptoms. These are called silent heart attacks. All women should know and talk about their risk factors for heart attack with their doctor or nurse.

If you think you, or someone else, may be having a heart attack, call 911 right away. Do not drive yourself to the hospital, and do not let a friend drive you. You may need medical help on the way to the hospital. Ambulance workers are trained to treat you on the way to the emergency room.

Getting to the hospital quickly is important. Treatments for opening clogged arteries work best within the first hour after a heart attack starts.

If you think you're having a heart attack, get emergency help right away. Don't let anyone tell you that you are overreacting or to wait and see. Get tips on how best to describe your symptoms and how to ask for tests that can show whether you're having a heart attack.

A silent heart attack is a heart attack that does not cause obvious symptoms. Your doctor may discover a silent heart attack days, weeks, or months later on an electrocardiogram test used to diagnose a heart problem.

Silent heart attack:

• Is more common in women than in men
• Can happen to women younger than 65. Younger women who have silent heart attacks without chest pain are more likely to die compared to younger men who have silent heart attacks without chest pain.²
• Is more likely to happen in women with diabetes. Diabetes can change how you sense pain, making you less likely to notice heart attack symptoms.³
