Complications of Atherosclerosis
Atherosclerosis can lead to life-threatening complications if the artery becomes severely narrowed or a plaque ruptures, triggering a blood clot. Learn more about the complications of atherosclerosis below.
1. Heart Attack (Myocardial Infarction)
- Occurs when blood flow to part of the heart is blocked
- Symptoms: Chest pain, shortness of breath, sweating, nausea
2. Stroke
- Caused by reduced or blocked blood supply to the brain
- Symptoms: Sudden numbness, slurred speech, vision loss, confusion
3. Peripheral Artery Disease (PAD)
- Poor circulation in the legs causes:
- Cramping, pain when walking
- Slow-healing wounds
- Cold or pale legs/feet
4. Aneurysm
- A bulge in an artery that may rupture and cause internal bleeding
- Common in the aorta (abdominal or thoracic)
5. Chronic Kidney Disease
- Narrowed renal arteries reduce kidney function over time
6. Sudden Cardiac Death
- A ruptured plaque may trigger fatal arrhythmias
Prevention of Complications
- Control blood pressure, sugar, and cholesterol
- Take medications as prescribed
- Keep regular follow-ups and lab checks
- Recognise emergency symptoms early (e.g. stroke or chest pain)
With proper treatment and lifestyle changes, many people with atherosclerosis can live full, active lives and prevent serious events like heart attacks or strokes.
