6 Possible Warning Signs Your Body May Give Before a Heart Attack
A heart attack can sometimes happen suddenly, but many people experience warning symptoms days, weeks, or even longer beforehand. These signs are not always obvious, and they can be caused by many other conditions, but they should not be ignored—especially if they are new, worsening, or occur together.
1. Chest discomfort or pressure
- A feeling of squeezing, fullness, heaviness, burning, or pressure in the chest.
- It may come and go or occur during activity or stress.
2. Unusual shortness of breath
- Feeling out of breath during normal activities.
- It may occur with or without chest discomfort.
3. Unexplained fatigue
- Extreme tiredness that is unusual for you.
- Some people, especially older adults and women, may notice fatigue before a heart event.
4. Pain or discomfort in other areas
Heart-related discomfort can sometimes spread to:
- One or both arms
- Shoulder
- Back
- Neck
- Jaw
- Upper stomach area
5. Dizziness, lightheadedness, or fainting
- Reduced blood flow to the heart or abnormal heart rhythms can sometimes cause these symptoms.
6. Sweating, nausea, or indigestion-like symptoms
- Cold sweating
- Nausea or vomiting
- A feeling similar to severe indigestion
When to seek emergency help
Call emergency services immediately if you experience:
- Chest pressure or pain lasting more than a few minutes
- Chest discomfort that returns or worsens
- Shortness of breath with chest symptoms
- Fainting, severe weakness, or signs of stroke
