What Happens During a Heart Attack? Symptoms & Emergency Care

What Is a Heart Attack?

A heart attack happens when blood flow to part of the heart muscle is suddenly blocked, often by a clot formed over a fatty buildup in the arteries. Without enough oxygen, that section of the heart begins to suffer damage within minutes. Doctors call this event a myocardial infarction. What’s important to understand is that the heart doesn’t stop instantly; it struggles as the muscle cells start dying. How quickly someone gets help determines how much of the heart can be saved. That’s why knowing what happens during a heart attack can make all the difference in recovery.

Causes of a Heart Attack

One of the main causes of a heart attack is reduced blood flow to the heart muscle. Over the years, fatty deposits known as plaque slowly line the artery walls, a process doctors call atherosclerosis. When one of these plaques breaks open, a blood clot can suddenly form and block the artery, cutting off oxygen to part of the heart.

Sometimes, even without a blockage, a brief spasm in the coronary artery can stop blood flow for a few moments and trigger an attack.

A few everyday factors make this more likely:

• Smoking or high blood pressure.

• High cholesterol or diabetes.

• Obesity, inactivity, and stress.

• A family history of heart disease.

Key Symptoms and Warning Signs

Recognizing heart attack symptoms early can save a life. The discomfort isn’t always sudden or dramatic; it can start mildly and build up over minutes. What matters is not ignoring what your body is trying to tell you.

Common signs of a heart attack include:

• Chest pressure, tightness, or a heavy, squeezing pain that lasts more than a few minutes.

• Pain that spreads to the arm, shoulder, neck, jaw, or back.

• Shortness of breath, sometimes even without chest pain.

• Breaking into a cold sweat, feeling sick, dizzy, or faint.

This type of chest pain in a heart attack is the body’s way of signalling an emergency. When these heart attack symptoms appear, it’s important to seek medical help immediately instead of waiting for them to pass.

Early Symptoms and Gender Differences

Sometimes the body gives subtle clues before a major attack. These early symptoms of a heart attack can appear hours or even days in advance. Many people dismiss them as tiredness or indigestion, but they often signal that blood flow to the heart is already reduced.

Men

In men, the warning signs tend to be more typical and easier to recognize:

• Crushing or squeezing pain in the center of the chest.

• Pain spreading to the left arm or shoulder.

• Shortness of breath, especially with activity.

• Sudden sweating or lightheadedness.

Women

In women, the pattern of heart attack symptoms can look quite different, which is why many delay seeking help:

• Unusual fatigue or weakness.

• Dizziness or nausea.

• Vomiting or a feeling of indigestion.

• Pain in the jaw, neck, upper back, or shoulders.

Recognising these heart attack symptoms or warning signs and understanding that heart attack pain location isn’t always limited to the chest can help people get help before severe damage occurs.

Heart Attack vs Cardiac Arrest

People often mix up the two, but they are not the same. The table below shows how they differ and why both need urgent care.

What to Do in a Heart Attack: First Aid and Emergency Response

When someone shows signs of a heart attack, every minute counts. Knowing what to do in a heart attack can keep blood flowing and improve their chances of survival before medical help arrives.

Step-by-step response:

• Call the emergency helpline immediately: Do not try to drive yourself or wait for symptoms to fade. (Manipal MARS No. 080 2222 1111).

• Sit down and stay calm: resting reduces the strain on the heart while waiting for help.

• Give first aid for a heart attack: if advised by a doctor, chew one regular aspirin to help thin the blood and improve circulation.

• Avoid eating, drinking, or moving around: Any physical activity can worsen the heart’s oxygen demand.

• If the person collapses and isn’t breathing, start CPR: Push hard and fast in the centre of your chest until emergency responders take over.

Diagnosis and Treatment

When someone reaches the hospital with chest pain or related symptoms, doctors move fast to confirm a heart attack diagnosis. It involves finding the blockage and restoring blood flow as quickly as possible.

How doctors confirm it:

Once confirmed, heart attack treatment starts immediately.

• Medicines like antiplatelets and beta-blockers help prevent further clotting and reduce the heart’s workload.

• In more serious cases, angioplasty may be done to open the blocked artery or bypass surgery to create a new route for blood to reach the heart.

Recovery After a Heart Attack

Life after a heart attack can feel different at first, but it’s also the beginning of getting stronger and learning how to care for your heart in a new way. Recovery after a heart attack is about healing both the body and mind, with steady progress over time.

After discharge, here’s what usually follows:

• You’ll likely join a cardiac rehab program, where a team helps you build strength safely through gentle exercise and guidance.

• Your doctor will talk about a few lifestyle changes. You will have to quit smoking, eat balanced, heart-friendly meals, stay active, and take medicines exactly as prescribed.

• Emotional recovery is just as important. Feeling anxious, worn out, or even scared is normal. Support from family, friends, or a counsellor can make it easier.

Conclusion

Recognizing symptoms early, acting quickly, and staying committed to recovery can save a life, sometimes your own. If you ever notice chest discomfort, shortness of breath, or unusual fatigue, don’t wait to see if it passes.
