Important: symptoms depend on where arteries are blocked
There is no single “10 symptom checklist.” Instead, signs depend on location:
❤️ Heart (coronary arteries)
Possible warning signs:
- Chest pain or pressure (especially with activity)
- Shortness of breath
- Fatigue with minimal exertion
- Pain spreading to arm, jaw, or back
This can indicate angina or heart disease.
🧠 Brain (carotid arteries)
Possible signs of reduced blood flow:
- Sudden weakness or numbness on one side
- Trouble speaking or understanding
- Vision changes in one eye
- Dizziness or loss of balance
These can be signs of a stroke or TIA (mini-stroke) and need emergency care.
🦵 Legs (peripheral arteries)
Often called PAD:
- Leg pain while walking (claudication)
- Cold feet or legs
- Slow-healing wounds on feet
- Weak pulse in legs
🧠 General warning signs (non-specific)
These can occur but are NOT proof of blocked arteries alone:
- Persistent fatigue
- Reduced exercise tolerance
- High blood pressure history
🚨 When to seek urgent help
Get emergency care if there is:
- Chest pain lasting more than a few minutes
- Sudden weakness, speech trouble, or facial droop
- Severe shortness of breath
🧠 Key reality check
- Atherosclerosis develops slowly over years
- Many people have no symptoms until a major event
- Diagnosis requires medical tests (ECG, blood tests, imaging), not symptom lists alone
