What are symptoms of a heart attack?

The most common symptoms of a heart attack include:

* Chest pain or discomfort. This is the most common symptom of a heart attack. The pain is often described as pressure, squeezing, or tightness in the chest. It may also feel like a burning or aching sensation. The pain can last for more than a few minutes and may come and go.

* Shortness of breath. This is another common symptom of a heart attack. You may feel like you can't catch your breath or that you're suffocating.

* Pain in the arms, neck, back, or jaw. The pain from a heart attack can sometimes spread to other parts of your body, such as your arms, neck, back, or jaw.

* Nausea, vomiting, or light-headedness. These are also common symptoms of a heart attack. You may feel sick to your stomach, vomit, or feel like you're going to faint.

* Sweating. You may also sweat during a heart attack. The sweat may be cold or clammy.

If you experience any of these symptoms, it's important to call 911 immediately. A heart attack is a medical emergency, and the sooner you get treatment, the better your chances of survival.
