A heart attack can happen suddenly, but in many cases, the body sends warning signs hours, days, or even weeks beforehand. Unfortunately, many people dismiss these symptoms as stress, indigestion, or fatigue until it is too late.
Recognising the early signs of a heart attack could save your life or the life of someone you love.
What Is a Heart Attack?
A heart attack occurs when blood flow to part of the heart muscle is blocked, usually by a blood clot. Without enough oxygen-rich blood, part of the heart begins to die if treatment is delayed.
Heart disease is one of the leading causes of death worldwide, but prompt medical attention significantly improves survival.
Warning Signs You Should Never Ignore
Chest Pain or Discomfort
This is the most common symptom. You may feel pressure, squeezing, heaviness, tightness, or pain in the centre or left side of your chest. The discomfort may last several minutes or come and go.
Pain That Spreads
Pain may spread from the chest to the arms—especially the left arm—as well as the shoulders, neck, jaw, back, or upper stomach.
Shortness of Breath
Difficulty breathing may occur before or during chest pain. Some people experience breathlessness even while resting.
Cold Sweats
Breaking out into an unexplained cold sweat, especially when combined with chest discomfort, should be treated as a medical emergency.
Nausea or Vomiting
Some heart attacks begin with nausea, vomiting, indigestion, or stomach discomfort, making them easy to mistake for food poisoning or acid reflux.
Extreme Fatigue
Feeling unusually tired for several days or weeks without a clear reason—especially in women—can be an early warning sign.
Dizziness or Lightheadedness
Feeling faint, weak, or suddenly dizzy may indicate that the heart is struggling to pump enough blood.
Irregular Heartbeat
A racing, pounding, or irregular heartbeat accompanied by chest discomfort or breathlessness requires immediate medical attention.
Symptoms Can Be Different in Women
Women are more likely than men to experience symptoms such as:
Unusual fatigue
Shortness of breath
Nausea
Back pain
Jaw pain
Neck pain
Lightheadedness
Because these symptoms can be less obvious, women sometimes delay seeking treatment.
Who Is Most at Risk?
You may have a higher risk of a heart attack if you:
Have high blood pressure
Have diabetes
Smoke cigarettes
Are overweight or obese
Have high cholesterol
Rarely exercise
Eat an unhealthy diet
Drink excessive alcohol
Have a family history of heart disease
Experience chronic stress
What Should You Do If You Think You’re Having a Heart Attack?
If you experience chest pain lasting more than a few minutes or several of the symptoms above:
Call emergency medical services immediately or get someone to take you to the nearest hospital.
Do not attempt to drive yourself if possible.
Stay calm and sit down while waiting for help.
If advised by a healthcare professional and you are not allergic, chewing an aspirin may help reduce blood clotting while awaiting emergency care.
Every minute counts during a heart attack.
How to Protect Your Heart
The good news is that many heart attacks are preventable through healthy lifestyle choices. You can lower your risk by:
Exercising for at least 30 minutes most days of the week.
Eating more fruits, vegetables, whole grains, and lean proteins.
Limiting salt, sugar, and unhealthy fats.
Avoiding smoking and second-hand smoke.
Maintaining a healthy weight.
Controlling blood pressure, cholesterol, and blood sugar levels.
Limiting alcohol intake.
Managing stress through relaxation, sleep, and physical activity.
Going for regular medical check-ups, especially if you have risk factors.
Final Thoughts
A heart attack rarely happens without warning. Learning to recognise the signs and acting quickly could mean the difference between life and death. Never ignore persistent chest pain, unexplained shortness of breath, or sudden severe fatigue.
Protecting your heart starts with healthy daily habits and taking any warning signs seriously.
