Heart attacks don’t always look dramatic—but ignoring early warning signs can be deadly. Quick recognition and immediate first aid can limit heart damage and save lives.

Knowing these signs and how to respond is a critical part of CPR and first aid certification and emergency preparedness.

What Is a Heart Attack?

A heart attack (myocardial infarction) occurs when blood flow to part of the heart muscle is blocked, usually by a clot. Without oxygen, heart tissue begins to die.

Early action can:

  • Reduce heart damage
  • Improve survival rates
  • Prevent cardiac arrest

Warning Signs You Should Never Ignore

Chest Discomfort

  • Pressure, squeezing, fullness, or pain
  • May last more than a few minutes or come and go

Upper Body Pain

  • Pain in arms, back, neck, jaw, or stomach

Shortness of Breath

  • May occur with or without chest pain

Other Common Symptoms

  • Cold sweat
  • Nausea or vomiting
  • Lightheadedness or dizziness

⚠️ Women, older adults, and people with diabetes may experience subtler symptoms such as fatigue or indigestion-like discomfort.

Step 1: Call Emergency Services Immediately

If you suspect a heart attack:

  • Call emergency services right away
  • Do not wait to see if symptoms improve
  • Early medical care saves heart muscle

Time is the most critical factor.

Step 2: Keep the Person Calm and Resting

While waiting for help:

  • Have the person sit or lie down
  • Loosen tight clothing
  • Keep them warm and calm

Avoid physical exertion.

Step 3: Assist With Medication (If Prescribed)

If the person has been prescribed heart medication:

  • Help them take nitroglycerin if directed
  • If not allergic and advised by emergency services, aspirin may be recommended

Never give medication unless appropriate.

Step 4: Be Ready for CPR

A heart attack can suddenly lead to cardiac arrest. If the person:

  • Becomes unresponsive
  • Is not breathing normally

Begin CPR immediately and use an AED if available. These lifesaving skills are taught in CPR certification and basic life support certification programs.
