The 7 Major Signs of a Heart Attack (Seek Emergency Care NOW)

A heart attack can present in varied and subtle ways. If you experience any combination of the following, do not hesitate—call emergency services immediately.

1. Chest Pain, Pressure, or Discomfort: This is the most common symptom, often described as an intense pressure, tightness, squeezing, or burning sensation. It signals that a part of your heart muscle is being starved of oxygen due to a blocked artery.

2. Numbness or Discomfort in Other Areas: Pain can radiate to your upper body. The classic sign is an ache or numbness down your left arm, but it can also appear in the jaw, back, neck, or stomach.

3. Nausea and Vomiting: Feeling intensely sick to your stomach is a very common heart attack symptom, particularly in women. The stress on your heart can affect the vagus nerve, which influences digestion.

4. Dizziness or Lightheadedness: An ineffective heart cannot pump enough oxygen-rich blood to the brain, causing you to feel dizzy, unsteady, or like you’re about to faint.

5. Breaking Out in a Cold Sweat: Suddenly sweating profusely when you are not exercising or in a hot environment is a significant red flag. Your nervous system is triggered into "fight-or-flight" mode, causing a cold, clammy sweat.

6. A Feeling of Intense Anxiety: Many heart attack patients report a sudden, overwhelming, and unexplainable sense of impending doom or intense anxiety.

7. Shortness of Breath: Feeling like you can’t catch your breath, even when you are at rest. This occurs because the heart's inability to pump efficiently causes fluid to back up and leak into the lungs.

The Single Most Important Warning Sign: Understanding Angina

This is the single most crucial warning your heart can give you, and it's frequently ignored because the pain subsides.

Angina is chest pain or discomfort that is reliably triggered by physical activity or stress and goes away completely with rest.

Why It's Deadly to Ignore

Angina is your heart screaming for help. It signals a partially blocked artery. When you exert yourself, your heart demands more oxygen, but the blockage prevents sufficient blood flow, causing pain. When you rest, the heart's demand drops, and the pain disappears.

People mistakenly think, "The pain is gone, so I'm fine." In reality, angina means you have significant underlying coronary artery disease and are at high risk for a full-blown heart attack where the artery becomes completely blocked.

If you experience pain that consistently follows this pattern, you must see a doctor immediately.

Your health is in your hands. By understanding these emergency signs and proactively managing your risk factors, you can build a strong foundation for long-term cardiovascular health and ensure you never ignore the one warning sign that could save your life.
