Stopping a heart attack in 30 seconds is not realistically possible on your own, but immediate actions can significantly improve survival chances and reduce heart damage while waiting for emergency medical help.
What to Do Immediately If Someone Is Having a Heart Attack
- Call emergency services (911 or local emergency number) immediately. This is the most crucial step
- Have the person sit down, rest, and stay calm. Sitting with knees bent and supported reduces strain on the heart and lowers the risk of injury if they collapse
- Loosen tight clothing to help comfort and breathing
- Give aspirin if the person is conscious and not allergic. Chewing a standard dose (usually 300 mg) helps thin the blood and improve blood flow to the heart
- Assist with nitroglycerin if prescribed. Only give if the person has a prescription for it
- Monitor the person closely, reassure them, and be ready to act if they become unresponsive.
If the Person Becomes Unresponsive and Stops Breathing
- Start CPR immediately. Place hands on the center of the chest and push hard and fast at a rate of 100–120 compressions per minute, compressing the chest about 2 inches deep
- Use an Automated External Defibrillator (AED) if available. It can deliver a shock to restore normal heart rhythm
Important Notes
- There is no proven way to stop a heart attack instantly by yourself in 30 seconds.
- Quick medical treatment with clot-busting drugs or procedures is essential to stop the heart attack and limit heart damage
- Avoid delaying calling emergency services to try other interventions.
In summary, the best immediate response involves calling for emergency help, keeping the person calm and seated, administering aspirin if appropriate, and performing CPR if they lose consciousness and stop breathing. These steps maximize the chance of survival until professional care arrives
