Never Ignore These 11 Heart Symptoms

3. Pain that Spreads to the Arm

Another classic heart attack symptom is pain that radiates down the left side of the body.

"It almost always starts from the chest and moves outward," Chambers says. "But I have had some patients who have mainly arm pain that turned out to be heart attacks."

4. You Feel Dizzy or Lightheaded

A lot of things can make you lose your balance or feel faint for a moment. Maybe you didn’t have enough to eat or drink, or you stood up too fast.

But if you suddenly feel unsteady and you also have chest discomfort or shortness of breath, call a doctor right away.

"It could mean your blood pressure has dropped because your heart isn't able to pump the way it should," Bufalino says.

5. Throat or Jaw Pain

By itself, throat or jaw pain probably isn't heart related. More likely, it's caused by a muscular issue, a cold, or a sinus problem.

But if you have pain or pressure in the center of your chest that spreads up into your throat or jaw, it could be a sign of a heart attack. Call 911 and seek medical attention to make sure everything is all right.

6. You Get Exhausted Easily

If you suddenly feel fatigued or winded after doing something you had no problem doing in the past -- like climbing the stairs or carrying groceries from the car -- make an appointment with your doctor right away.

"These types of significant changes are more important to us than every little ache and pain you might be feeling," Bufalino says.

Extreme exhaustion or unexplained weakness, sometimes for days at a time, can be a symptom of a heart attack, especially for women. 

7. Snoring

It’s normal to snore a little while you snooze. But unusually loud snoring that sounds like a gasping or choking can be a sign of sleep apnea. That’s when you stop breathing for brief moments several times at night while you are still sleeping. This puts extra stress on your heart.

Your doctor can check whether you need a sleep study to see if you have this condition. If you do, you may need a CPAP machine to smooth out your breathing while you sleep.
