At the Canadian Health Care Provider Training Institute (CHCPT), we believe that education saves lives. Recognizing the early warning signs of a cardiovascular emergency is the first step in the Chain of Survival. Whether you are a healthcare professional or a concerned citizen, knowing when to act is critical.
1. Recognizing a Heart Attack
A heart attack occurs when blood flow to the heart muscle is blocked. Minutes matter. If you or someone around you experiences these symptoms, call 9-1-1 immediately.
Common Signs & Symptoms:
- Chest Discomfort: Feeling of pressure, squeezing, fullness, pain, burning, or “heaviness” in the chest.
- Upper Body Pain: Discomfort radiating to the neck, jaw, shoulders, back, or either arm.
- Shortness of Breath: Difficulty breathing, with or without chest pain.
- Physical Distress: Sudden cold sweats, nausea, or light-headedness.
Important: Heart Attack Signs in Women
Women may not always experience the classic “crushing chest pain.” Be alert for these more subtle indicators:
- Extreme fatigue or exhaustion.
- Pain or pressure in the lower chest or upper abdomen.
- Vague discomfort in the upper back.
- Dizziness or fainting.
2. Critical Action Steps: What to Do
If a heart attack is suspected, follow these life-saving steps:
- Call 9-1-1: Do not wait. State clearly that you suspect a heart attack.
- Locate an AED: Shout for an Automated External Defibrillator.
- Stop All Activity: Have the person sit or lie down in a comfortable position.
- Aspirin (ASA): If the person is not allergic or intolerant, have them chew and swallow one 325mg tablet or two 81mg tablets.
- Nitroglycerin: If the person has a personal prescription, help them take their usual dose.
- Stay Calm: Wait with the person until emergency responders arrive.
3. Cardiac Arrest: A Medical Emergency
Cardiac arrest is different from a heart attack; it is an “electrical” problem where the heart stops beating entirely. Brain injury can begin in as little as three minutes.
The Red Flags:
- Sudden Collapse: The person falls unexpectedly.
- Unresponsiveness: No response to touch or shouting.
- Abnormal Breathing: The person is not breathing or is only making occasional gasping sounds (agonal breathing).
The “Call-Push-Shock” Protocol:
- CALL: Dial 9-1-1 and send someone to find an AED.
- PUSH: Begin high-quality CPR immediately. Push hard and fast in the center of the chest (100–120 bpm).
- SHOCK: As soon as an AED arrives, turn it on and follow the voice prompts.
4. Sudden Arrhythmia Death Syndromes (SADS)
SADS refers to genetic heart conditions that can cause sudden death in young, seemingly healthy individuals. Warning signs include:
- Fainting or seizures during physical activity.
- Fainting caused by a sudden startle or emotional distress.
- A family history of sudden, unexplained death at a young age.
