Introduction
A heart attack is one of the leading medical emergencies worldwide. It occurs when blood flow to part of the heart is blocked, preventing the heart muscle from receiving enough oxygen. Without prompt treatment, permanent heart damage or death can occur.
Knowing how to recognize the warning signs and provide immediate first aid can make a significant difference while waiting for emergency medical professionals.

What Is a Heart Attack?
A heart attack (also called a myocardial infarction) happens when one or more coronary arteries become blocked, usually due to fatty deposits known as plaque. When blood flow is interrupted, part of the heart muscle begins to die if treatment is delayed.
Heart attacks are different from heart failure. Heart failure is a chronic condition where the heart cannot pump blood efficiently, while a heart attack is a sudden emergency caused by blocked blood flow.
Common Causes
Several conditions increase the risk of a heart attack, including:
- Coronary artery disease
- High blood pressure (hypertension)
- High cholesterol
- Smoking
- Diabetes
- Obesity
- Physical inactivity
- Excessive alcohol consumption
- Chronic stress
- Family history of heart disease
Warning Signs
Seek emergency medical help immediately if someone experiences:
- Chest pain or pressure
- Pain spreading to the arm, neck, jaw, shoulder, or back
- Shortness of breath
- Cold sweat
- Nausea or vomiting
- Dizziness or light-headedness
- Unusual fatigue
- Rapid or irregular heartbeat
Women, older adults, and people with diabetes may have less typical symptoms such as fatigue, nausea, or shortness of breath without severe chest pain.
First Aid Steps for a Heart Attack
1. Call Emergency Medical Services Immediately
Call your local emergency number as soon as you suspect a heart attack. Early treatment greatly improves survival.
2. Help the Person Sit Comfortably
Help the person sit down in a comfortable position, usually leaning slightly back with knees bent.
Keep them calm and reassure them while waiting for medical help.
3. Loosen Tight Clothing
Loosen ties, collars, belts, or any tight clothing that may make breathing uncomfortable.
4. Assist With Prescribed Medication
If the person has been prescribed nitroglycerin (glyceryl trinitrate) for heart disease, help them take it exactly as directed by their healthcare provider.
Do not give someone else's medication.
5. Give Aspirin (If Appropriate)
If the person is conscious, not allergic to aspirin, not experiencing active bleeding, and has been advised by emergency personnel or local first aid guidance, have them chew one standard adult aspirin (typically 300–325 mg, depending on local recommendations). Chewing helps it work faster.
Do not give aspirin if they have a known allergy or another reason they should avoid it.
6. Monitor Their Condition
Stay with the person until medical professionals arrive.
Watch for:
- Changes in breathing
- Loss of consciousness
- Worsening chest pain
7. Begin CPR Only If Necessary
If the person becomes unresponsive and is not breathing normally, begin CPR immediately after calling emergency services or asking someone else to call.
- Push hard and fast in the center of the chest.
- Aim for 100–120 compressions per minute.
- Continue until emergency responders arrive or the person begins breathing normally.
- If an Automated External Defibrillator (AED) is available, use it as soon as possible by following its voice prompts.

How to Reduce Your Risk
Many heart attacks can be prevented by maintaining a healthy lifestyle.
Quit Smoking
Smoking significantly increases the risk of heart disease.
Eat a Heart-Healthy Diet

- Fruits
- Vegetables
- Whole grains
- Lean proteins
- Healthy fats
Limit:
- Salt
- Sugar
- Saturated fats
- Processed foods
Exercise Regularly
Aim for at least 150 minutes of moderate physical activity each week.
Control Blood Pressure
High blood pressure damages arteries over time.
Manage Cholesterol
Regular check-ups and healthy eating help keep cholesterol under control.
Maintain a Healthy Weight
Being overweight increases the workload on the heart.
Control Diabetes
Keeping blood sugar under control greatly reduces cardiovascular risk.
Attend Regular Medical Check-ups
Routine health screenings can detect problems before they become serious.
Recovery After a Heart Attack
Many people recover well after a heart attack, especially when treatment begins quickly.
Recovery often includes:
- Cardiac rehabilitation
- Taking prescribed medications
- Lifestyle changes
- Regular exercise
- Healthy eating
- Stress management
- Follow-up appointments with healthcare providers
With proper care, many people return to active and fulfilling lives.
