I never added up the symptoms. I thought maybe it was indigestion or stress anxiety as I was heading to work.

On my next visit to the doctor, I want to be prepared.

Questions to Ask Your Doctor

I'm willing to try a new treatment or medication.

Your heart muscle needs oxygen and nutrients to work as it should. A heart attack (your doctor may call it a myocardial infarction) usually occurs when blood flow to the heart is suddenly cut off. When this happens, the heart muscle is starved of oxygen-rich blood. In just a short period of time, part of the heart can be damaged or die. That’s why immediate care is critical—it can spare your heart and save your life. If you think you are having a heart attack, dial 9-1-1 immediately.

If you’ve had a heart attack, you know how scary it can be. And you’re not alone. Over a million Americans have a heart attack each year.

Unfortunately, once you’ve had a heart attack, your chance of having another one is higher. But, there are steps you can take to protect your heart. Taking prescribed medications, following an exercise program tailored to you, maintaining a healthy weight and being careful about what you eat can all help keep your heart healthy. Controlling your blood pressure and lowering cholesterol are also important steps to help prevent another heart attack.

No two heart attacks are the same. If you’ve already had a heart attack, listen to your body. A repeat attack may feel very different. Both men and women can feel the classic crushing chest pain or tightness (called unstable angina), but they often report very different symptoms. Some people might instinctively know it’s a heart attack, others have more subtle symptoms.

Knowing the symptoms of a heart attack and getting treated right away can save your life. Use this condition center to learn more.
