Is a Feeling of Impending Doom a Sign of a Heart Attack?
The phrase “impending doom” may sound dramatic, but it’s a real sensation experienced by many during medical emergencies. It refers to a sudden and overwhelming sense that something terrible is about to happen. While it can occur during panic attacks or moments of high anxiety, it’s also reported by people having heart attacks. So, is a feeling of impending doom an actual warning sign of a heart attack?
In this article, we explore the science behind this ominous sensation, its connection to cardiac events, and when to seek emergency help.
What Is the Feeling of Impending Doom?
The feeling of impending doom is often described as a deep, instinctive sense that something life-threatening is imminent. People experiencing it may say:
- “I feel like I’m going to die.”
- “Something is terribly wrong, I just know it.”
- “I can’t shake this horrible feeling.”
This reaction can occur even when there are no obvious physical symptoms at first. It’s commonly associated with anxiety disorders, panic attacks, severe allergic reactions, and yes—heart attacks.
The Link Between Impending Doom and Heart Attacks
Many people who survive heart attacks report a sensation of impending doom just before or during the event. This isn't just psychological—it’s a legitimate clinical symptom recognised in emergency medicine.
Why it happens:
- The body enters a state of extreme stress as the heart struggles to pump blood.
- Oxygen deprivation to the brain can heighten fear and anxiety.
- The autonomic nervous system triggers a fight-or-flight response.
Medical professionals consider a report of “feeling of doom” seriously, especially when accompanied by physical symptoms.
Heart Attack Symptoms to Watch Alongside Impending Doom
The sensation alone isn’t proof of a cardiac event—but when paired with other symptoms, it can be a red flag. Be alert if the feeling occurs with:
- Chest pain or pressure (like an elephant sitting on your chest)
- Shortness of breath
- Pain radiating to arms, neck, jaw, or back
- Nausea or vomiting
- Cold sweats
- Light-headedness or dizziness

How Common Is It?
Studies show that up to 17% of heart attack patients reported a sudden sense of doom before or during the event. This symptom is more likely to be reported by women, who also tend to experience “atypical” heart attack symptoms that differ from the classic chest pain model.
Why Women Should Take This Sign Seriously
Women often experience subtler heart attack symptoms, which can delay diagnosis and treatment. A feeling of dread or doom may be one of the few early signals.
Other atypical symptoms in women:
- Fatigue
- Indigestion
- Sleep disturbances
- Upper back or jaw pain

Other Conditions That Cause This Feeling
Not every sense of doom means a heart attack. Other conditions may produce this symptom too, including:
1. Panic Attack
Sudden onset of fear, rapid heartbeat, hyperventilation, dizziness, and chest tightness can mimic a heart attack.
2. Anaphylaxis
This severe allergic reaction often begins with a sense of impending doom, followed by swelling, rash, difficulty breathing, and drop in blood pressure.
3. Pulmonary Embolism
A blood clot in the lungs may cause chest pain, shortness of breath, and intense fear or dread.
4. Stroke
Though less common, strokes can also cause cognitive changes that trigger a profound sense of distress or doom.
5. Sepsis or Septic Shock
When the body responds severely to infection, it may result in mental confusion and fear, including the feeling of doom.
Should You Go to A&E If You Feel This Way?
Yes. If the sensation of impending doom appears suddenly and is accompanied by physical symptoms—especially chest pain, shortness of breath, or numbness—it’s a medical emergency.
When to call 999 or visit A&E:
- Unexplained chest pain or tightness
- Shortness of breath or dizziness
- Pain in the jaw, shoulder, or arm
- Nausea and cold sweat
- Sudden and severe sense that something is very wrong
Time is muscle in heart attacks—the faster you seek help, the better your chance of survival and recovery.
How Is It Diagnosed?
If you visit A&E with a feeling of impending doom and other symptoms, doctors may conduct several tests:
- ECG (electrocardiogram)
- Blood tests (e.g. troponin levels)
- Chest X-ray
- Blood pressure and oxygen monitoring
They will also ask about your medical history, risk factors, and the exact nature of your symptoms.
How Can You Tell If It’s Anxiety or Something Worse?
This can be very difficult—even experienced clinicians sometimes struggle to differentiate. However, anxiety and heart attacks have a few key differences:
| Feature | Heart Attack | Anxiety/Panic Attack |
|---|---|---|
| Chest Pain | Pressure, tightness, heavy sensation | Sharp or stabbing, may shift position |
| Duration | More than 10 minutes | Usually peaks within 10 minutes |
| Breathing | Laboured, short breath with exertion | Hyperventilation (rapid breathing) |
| Relief | Rest may not relieve symptoms | Breathing techniques may help |
| Other signs | Nausea, sweating, pain in other areas | Tingling, dizziness, fear of losing control |
If you’re unsure, always err on the side of caution and seek medical attention.
