If your doctor has told you that smoking, high blood pressure or cholesterol, an unhealthy diet, or your weight has put you at risk of a heart attack, it's time to familiarize yourself with the warning signs. While some of the symptoms related to a heart attack are well known, there are others you may not be familiar with—and these vary between men and women.

Warning signs for women

According to the American Heart Association, women are less likely than men to have chest pressure when a heart attack strikes. Females should look out for the following warning signs if they are at risk of a heart attack:

• Shortness of breath
• Jaw, neck, stomach, or back pain
• Nausea or vomiting
• Lightheadedness
• Breaking out in a cold sweat
• Pain or discomfort in one or both arms
• Shortness of breath

That being said, women may still have the uncomfortable chest pressure that is often associated with heart attacks. If experienced, this shouldn't last for more than a few minutes before subsiding and eventually returning. It's important that you not dismiss these symptoms, especially if your doctor has classified you as "at risk." Call 911 immediately.

Symptoms in men

Males are most likely to experience that "elephant-on-the-chest" type feeling when they have a heart attack, according to Healthline. In addition, look for these warning signs:

• Squeezing, pressure, or pain sensation in the upper body
• Pain in the jaw, neck, stomach, back, and arms
• Cold sweats, nausea, shortness of breath, and lightheadedness

If you're in danger of heart disease and have any of these symptoms, be sure to ask for emergency help at onset.
