1. Introduction

A heart attack is a life-threatening medical emergency. While it can be a terrifying experience for both the person experiencing it and those around them, knowing what to do in the first few minutes can make a critical difference. Recognizing the signs of angina and myocardial infarction and taking immediate action can save a life. This guide will provide a clear, step-by-step plan for responding to a suspected heart attack, empowering you to act with confidence in a crisis.





2. Understanding the Symptoms

First, it's important to understand the difference between angina and a myocardial infarction:

     
  • Angina: This is chest pain caused by reduced blood flow to the heart muscle. It's often a warning sign of underlying heart disease. The pain is typically temporary, lasting a few minutes, and often goes away with rest.
    •  
  • Myocardial Infarction (Heart Attack): This occurs when blood flow to the heart is completely blocked, causing heart muscle tissue to die. The symptoms are similar to angina but are more severe, sudden, and do not go away with rest. Common symptoms include:   




3. Immediate Emergency Steps

If you suspect someone is having a heart attack, every second counts. Follow these steps immediately:

     
  1. Call 911 (or your local emergency number) immediately. This is the single most important step. Don't wait to see if the symptoms get better.
    2.  
  2. Keep the Person Calm: Have the person sit or lie down in a comfortable position. Reassure them that help is on the way.
    3.  
  3. Administer Medication (if available): If the person has been prescribed nitroglycerin for angina, help them take it. If they are not allergic to aspirin, and you are instructed by a dispatcher, have them chew and swallow a regular-strength aspirin (325 mg).




4. What to Do if the Person is Unconscious

If the person becomes unconscious, it is a medical emergency. Follow these steps:

     
  • Check for a Pulse: If there is no pulse, begin CPR immediately. Push hard and fast on the center of the person's chest.
    •  
  • Use an AED: If an Automated External Defibrillator (AED) is available, turn it on and follow the verbal instructions provided by the device.




5. Expert Opinion: The Importance of Quick Action

Dr. Kim, a board-certified emergency physician, stresses the importance of rapid response. "When it comes to a heart attack, we have a saying: 'Time is muscle.' The quicker you get to the hospital and receive treatment, the more heart muscle we can save. The best thing a bystander can do is call for help immediately and, if instructed, administer aspirin. Don't waste time trying to drive them to the hospital yourself, as an ambulance can provide life-saving care en route."

6. Q&A with an Emergency Physician

     
  • Q: What's the difference between angina and a heart attack?
      A: Angina is a warning sign of reduced blood flow to the heart, while a heart attack is a complete blockage. The main difference is that angina pain typically subsides with rest, while a heart attack is more severe and persistent.
    •  
  • Q: Is aspirin safe to give?
      A: Yes, for most people. Aspirin helps thin the blood, which can prevent the blood clot from getting bigger. It should be chewed for faster absorption. However, do not give it if the person is allergic or is already on blood thinners.
    •  
  • Q: Can I drive the person to the hospital myself?
      A: No, it's highly recommended to call an ambulance. Paramedics can provide life-saving care in the ambulance, such as oxygen and pain medication, which you cannot do in a car.
    •  
  • Q: What if the person says no to my help?
      A: People having a heart attack can be disoriented or in denial. The priority is to call for professional help. You can then try to keep them calm while you wait for the paramedics to arrive.
    •  
  • Q: What if the symptoms go away on their own?
      A: Even if the symptoms subside, the person should still be taken to the hospital for a medical evaluation. It could have been angina, a warning sign that needs to be addressed.



7. Conclusion

The first few moments of a suspected heart attack are a critical window for intervention. By recognizing the symptoms of angina and myocardial infarction and taking immediate action—most importantly, calling for help—you can dramatically improve a person's chances of survival. Your quick thinking and a calm, confident response can be the difference between life and death. Be prepared, and you'll be ready to act when it matters most.
