The idea that you can save yourself from a heart attack in 10 seconds by coughing heavily (often called “cough CPR”) is a **widespread internet myth**.
Major medical organizations, including the American Heart Association, explicitly state that **cough CPR does not work for a heart attack and is not recommended.**
### Why It Doesn’t Work
* **Heart Attack vs. Cardiac Arrest:** A heart attack is a plumbing problem—a blocked coronary artery cuts off blood flow to part of the heart muscle. The heart usually keeps beating, but coughing cannot clear a blocked artery. Cardiac arrest, on the other hand, is an electrical problem where the heart stops beating entirely, rendering a person unconscious and unable to cough.
* **The Origin of the Myth:** The concept stems from rare, specialized hospital settings (like a cardiac catheterization lab) where doctors might briefly instruct a fully conscious, monitored patient to cough during a sudden, specific heart rhythm glitch to maintain consciousness for a few seconds. It is **not** a treatment for a heart attack at home.
* **Risks:** Relying on coughing wastes critical time and can actually increase stress on the heart, worsening your condition.

### What You Should Actually Do If You Suspect a Heart Attack at Home
If you are alone and experience warning signs of a heart attack (such as chest pain or pressure, shortness of breath, pain radiating to the arm or jaw, cold sweats, or sudden nausea):
1. **Call Emergency Services Immediately:** Dial your local emergency number (like 911) right away. Do not try to wait it out or drive yourself to the hospital.
2. **Unlock Your Door:** If possible, unlock your front door or let someone nearby know so emergency responders can get to you quickly if you lose consciousness.
3. **Sit or Lie Down:** Rest comfortably to reduce the strain on your heart.
4. **Take Aspirin (If Advised):** If you are not allergic and have aspirin on hand, emergency dispatchers may instruct you to chew and swallow one adult aspirin, which can help keep blood from clotting further while you wait for help.
