What Is a Heart Attack?

A heart attack usually occurs when a blood clot blocks a coronary artery that supplies oxygen-rich blood to the heart. Without rapid treatment, the affected heart muscle may become permanently damaged.

A heart attack is a medical emergency and requires immediate hospital treatment.

Common Heart Attack Symptoms

Warning signs may include:

• Severe chest pressure, squeezing, or heaviness
• Chest pain lasting several minutes
• Shortness of breath
• Cold sweating
• Nausea or vomiting
• Dizziness or fainting
• Pain spreading to the arm, shoulder, neck, jaw, or back

Some people, particularly women, older adults, and patients with diabetes, may experience unusual symptoms such as fatigue, indigestion, or breathing difficulty without severe chest pain.

What Causes a Heart Attack?

The most common cause is coronary artery disease. Plaque builds up inside a heart artery, ruptures, and triggers the formation of a blood clot.

Major risk factors include:

• High cholesterol
• High blood pressure
• Diabetes
• Smoking
• Obesity
• Physical inactivity
• Family history of heart disease
• Previous angina or heart attack

How Is a Heart Attack Diagnosed?

Emergency hospital testing may include:

• Electrocardiogram
• Cardiac enzyme blood tests
• Echocardiogram
• Coronary angiography
• Coronary CT or other cardiac imaging

Rapid diagnosis is essential because early restoration of blood flow can reduce heart muscle damage.

Heart Attack Treatment

Emergency treatment may include medication to prevent further clotting, coronary angioplasty and stent placement, or coronary artery bypass surgery.

After emergency treatment, ongoing cardiovascular care may involve:

• Antiplatelet medication
• Cholesterol-lowering medication
• Blood pressure management
• Diabetes control
• Heart function monitoring
• Cardiac rehabilitation
• Lifestyle and dietary guidance

Post-Heart Attack Follow-Up

Regular cardiology follow-up is important after myocardial infarction. Dr. Lim Do-Sun may monitor heart function, blood pressure, cholesterol, symptoms, medication response, and the risk of another cardiac event.

Patients should bring their hospital discharge summary, coronary angiography results, stent information, ECGs, blood tests, and current medication list.

When Should You Seek Emergency Care?

Call local emergency services immediately when chest pain:

• Is severe, new, or unexplained
• Lasts longer than a few minutes
• Occurs with sweating or nausea
• Spreads to the arm, jaw, neck, or back
• Causes breathing difficulty, weakness, or fainting

Do not travel to an outpatient clinic when an active heart attack is suspected.

Frequently Asked Questions

What is the difference between angina and a heart attack?

Angina is usually caused by temporarily reduced blood flow. A heart attack occurs when blood flow is blocked long enough to damage the heart muscle.

Can a heart attack happen without chest pain?

Yes. Some patients experience shortness of breath, fatigue, sweating, nausea, or jaw and back discomfort without typical chest pain.

What should I do when I suspect a heart attack?

Call emergency services immediately. Do not wait for symptoms to improve or attempt to visit an outpatient clinic.

Can the heart recover after a heart attack?

Recovery depends on the location and extent of heart muscle damage, how quickly treatment was received, and the patient’s overall health.

Why is follow-up necessary after a heart attack?

Follow-up helps monitor heart function, adjust medication, control risk factors, and reduce the likelihood of another cardiac event.

Can another heart attack be prevented?

The risk may be reduced through medication, smoking cessation, cholesterol and blood pressure control, diabetes management, exercise, and a heart-healthy diet.
