🔍 Quick Summary
A heart attack happens when blood flow to part of the heart becomes blocked, reducing oxygen supply to heart muscle.
Symptoms may include chest pressure, shortness of breath, sweating, nausea, or pain spreading to the arm, jaw, or back.
Fast recognition and emergency treatment can help reduce heart damage and improve survival.
1️⃣ Introduction
A heart attack is a medical emergency affecting the heart.
• the heart needs constant oxygen-rich blood to function properly
• blocked blood flow can damage heart muscle
• symptoms may range from mild discomfort to severe chest pain
👉 Not every heart attack looks dramatic. Some symptoms can be subtle, especially in women, older adults, and people with diabetes.
2️⃣ How it happens
The heart receives blood through coronary arteries.
• fatty plaque can build up inside these blood vessels over time
• a sudden blockage may stop blood flow to part of the heart
• lack of oxygen can injure or destroy heart muscle tissue
👉 Early treatment aims to restore blood flow before permanent damage becomes severe.
3️⃣ Types
• ST-elevation myocardial infarction (STEMI)
- severe artery blockage
- often causes significant heart muscle damage if untreated
• Non-ST-elevation myocardial infarction (NSTEMI)
- partial blockage or reduced blood flow
- symptoms may still be serious and need urgent care
• Silent heart attack
- mild or unusual symptoms
- more common in people with diabetes or older adults
👉 Some people mistake heart attack symptoms for indigestion, stress, or muscle pain.
4️⃣ Common causes
• Cardiovascular risk factors
• Lifestyle factors
- smoking
- physical inactivity
- obesity
• Other contributing factors
- chronic stress
- family history of heart disease
👉 Heart disease often develops gradually over many years before symptoms appear.
5️⃣ Symptoms
• chest pressure, tightness, or pain
• pain spreading to the arm, jaw, shoulder, or back
• shortness of breath, sweating, or nausea
👉 Heart attack symptoms happen because heart muscle is not receiving enough oxygen-rich blood.
6️⃣ Associated symptoms
• dizziness
• fainting
• unusual fatigue
• anxiety or feeling of impending doom
• cold sweats
👉 Symptoms may differ between individuals and may not always include severe chest pain.
7️⃣🩺 When it becomes dangerous 🚨
• severe or persistent chest pain
• difficulty breathing
• collapse, confusion
• loss of consciousness
👉 These may indicate:
• active heart attack
• life-threatening heart rhythm problems or cardiac arrest
8️⃣ Management / treatment
• call emergency services immediately
• keep the person calm and seated if possible
• emergency teams may provide oxygen, medications, or urgent heart procedures
👉 Do not delay medical care hoping symptoms will simply pass.
9️⃣ Diagnosis
• medical history and physical examination
• ECG (electrocardiogram) to assess heart activity
• blood tests and heart imaging investigations
👉 Blood tests can help identify damage to heart muscle cells.
🟢 Important message
Heart attacks are medical emergencies, but early recognition and treatment can save lives and reduce long-term heart damage.
Many people recover better when they seek help quickly instead of ignoring symptoms.
👉 Sudden chest discomfort or unexplained breathing difficulty should never be ignored.
