That message is a common viral claim, but it is not medically reliable.
If you think you’re having a heart attack at home, the most important actions are:
- Call your local emergency medical services immediately (or have someone else call). Don’t try to wait it out.
- Sit down and rest while waiting for help.
- If you’ve been prescribed nitroglycerin, take it as directed.
- If you’re not allergic to aspirin and have been told it’s safe for you, emergency guidelines often recommend chewing one regular-strength (325 mg) or four low-dose (81 mg) aspirin tablets while waiting for emergency services, unless a healthcare professional has advised you not to take aspirin (for example, because of certain bleeding disorders or allergies).
- Unlock your door if possible and let someone nearby know what’s happening.
About the “10 seconds” or “cough CPR” claim
You may see messages claiming you can save yourself by coughing repeatedly every few seconds. This is known as “cough CPR,” but it is not an appropriate self-treatment for a heart attack. It is only used in very limited, monitored hospital situations under the direction of medical professionals—not by someone alone at home.
Common heart attack symptoms
- Chest pain, pressure, tightness, or heaviness
- Pain spreading to the arm, jaw, neck, back, or shoulder
- Shortness of breath
- Cold sweat
- Nausea or vomiting
- Lightheadedness or fainting
Some people, especially women, older adults, and people with diabetes, may have less typical symptoms such as unusual fatigue, indigestion-like discomfort, or back or jaw pain.
