According to the U.S. Centers for Disease Control and Prevention (CDC), every 40 seconds, someone has a heart attack in this country. Every year, about 805,000 people have a heart attack. Of that number, 605,000 are first heart attacks. And 1 in 5 heart attacks is a silent one, meaning the person isn’t aware that it’s even happening.

So, what should you do if someone is having a heart attack? Interventional cardiologist Leslie Cho, MD, offers some helpful advice that can save a life.

Symptoms of a heart attack

Heart attack symptoms can range from shortness of breath to a feeling of impending doom. Some other common symptoms of a heart attack include:

  • Anxiety.
  • Chest pain or pressure (angina).
  • Discomfort in your arms, neck, back or jaw.
  • Heart palpitations.
  • Feeling lightheaded, dizzy or passing out.
  • Nausea or stomach discomfort.
  • Shortness of breath or trouble breathing.
  • Sweating.

While women have chest pain/pressure like men, they’re more likely to experience shortness of breath, nausea/vomiting and back or jaw pain.

Steps to take during a heart attack

In an emergency, it’s easy to panic. But staying calm helps ensure that your family member or friend (or even yourself) gets help — fast.

Step 1: Call 911

“A heart attack is a serious medical emergency and calling 911 is the fastest way to get lifesaving treatment,” stresses Dr. Cho. “This is because the emergency medical service workers can begin interventions immediately when they arrive and on the way to the hospital.”

Step 2: Take chest pain medicine

If you, or the person having the heart attack, have been prescribed chest pain medications, like nitroglycerin, use it. For those who don’t have chest pain medication, some healthcare providers recommend slowly chewing 325 milligrams of aspirin to help to minimize heart damage or prevent the development of a dangerous blood clot. But only do this if there isn’t a prior history of an aspirin allergy or a medical condition that could worsen because of it.

Step 3: Stay calm

As you’re waiting for emergency care, try to remain calm, loosen any clothing and rest. If you suspect you’re having a heart attack, don’t eat or drink anything outside of medication, and if someone else is having a heart attack, don’t allow them to do so either.

Start CPR if necessary

In the event the person you’re observing becomes unconscious and unresponsive, call 911 and check for a pulse. If there is no pulse, start CPR.

If it’s a child or infant, always do one minute of CPR before calling 911.

Why it’s so important to get help immediately

Again, if you have the slightest suspicion that someone (or even you) is having a heart attack, the first and most important thing to do is to call 911. Don’t call your healthcare provider or drive to the hospital. This can waste precious time for treatment. And certainly don’t wait and hope symptoms will disappear on their own. There’s no penalty if it turns out to be a false alarm.
