Possible warning signs (depend on location)
❤️ Heart-related arteries (coronary arteries)
- Chest pain or pressure (especially during activity)
- Shortness of breath
- Fatigue with mild exertion
- Pain spreading to arm, jaw, or back
🧠 Brain-related arteries (carotid arteries)
- Sudden weakness or numbness on one side
- Trouble speaking or understanding speech
- Vision problems in one eye
- Dizziness or loss of balance
These may indicate a stroke or mini-stroke (TIA) and require urgent care.
🦵 Leg arteries (peripheral circulation)
- Leg pain when walking (claudication)
- Cold feet or legs
- Slow-healing wounds on feet
- Weak pulses in lower limbs
🌿 General (non-specific) signs
- Unexplained fatigue
- Reduced exercise tolerance
- High blood pressure history
These alone are NOT proof of blockage.
🚨 Important warning
Seek emergency care if you experience:
- Chest pain lasting more than a few minutes
- Sudden speech difficulty or facial droop
- Sudden weakness on one side of the body
🧠 Key reality check
Atherosclerosis develops over years. Many people have no symptoms until a serious event occurs. Diagnosis requires medical tests like ECG, blood tests, ultrasound, or angiography—not symptom lists alone.
