What Is a Heart Attack?

A heart attack, also called myocardial infarction, happens when the heart muscle doesn’t get enough oxygen-rich blood. This usually occurs due to a blocked coronary artery caused by a blood clot or buildup of plaque. Unlike a mild chest pain or discomfort, a heart attack can be life-threatening and requires immediate medical attention.

Acting quickly and knowing what to do can make a critical difference.

Symptoms of a Heart Attack

Heart attack symptoms can vary from person to person. Common signs include:

• Chest pain or pressure — often described as tightness, squeezing, or heaviness

• Pain or discomfort in other areas — arms, neck, jaw, back, or stomach

• Shortness of breath

• Cold sweat, nausea, or vomiting

• Lightheadedness or dizziness

• Fatigue or unusual weakness

Some people, especially women, may experience less obvious symptoms, like nausea, shortness of breath, or jaw pain.

First Aid Steps During a Heart Attack

Immediate first aid can save lives and reduce heart damage. Follow these steps carefully:

1. Call emergency services immediately (911 or your local number). Time is critical.

2. Keep the person calm and seated. Encourage slow, steady breathing.

3. Chew one aspirin (if the person isn’t allergic and has no bleeding disorders) — this helps reduce blood clotting.

4. Monitor vital signs. If the person becomes unresponsive and isn’t breathing normally, begin CPR.

5. Use an AED (Automated External Defibrillator) if available and follow the device instructions.

Never wait for symptoms to subside. Acting fast is key to survival. For medically verified guidance, visit the Mayo Clinic Heart Attack First Aid Guide.

Prevention Tips

While first aid is essential during an attack, preventing a heart attack is equally important. Healthy habits include:

• Maintain a heart-healthy diet — limit salt, saturated fats, and processed foods

• Exercise regularly — at least 30 minutes most days

• Avoid smoking and limit alcohol

• Manage stress — stress can increase blood pressure and risk of heart disease. 

• Monitor blood pressure and vital signs regularly to detect risks early. 

Prevention reduces the risk and severity of heart attacks.

When to Seek Medical Help

Even if symptoms are mild or unusual, call emergency services immediately if you suspect a heart attack. Seek help if you notice:

• Severe chest pain or pressure

• Shortness of breath

• Pain spreading to arms, neck, jaw, or back

• Nausea, vomiting, or lightheadedness

Quick action is crucial. Don’t try to drive yourself — wait for professional help.

Complications

If untreated, a heart attack can lead to:

• Heart failure or reduced heart function

• Irregular heartbeats (arrhythmias)

• Cardiogenic shock

• Permanent heart muscle damage

Early first aid and prompt medical care reduce these risks significantly.
