Understanding Atherosclerosis Development

Revision sheet excerpt

Atherosclerosis Revision Sheet

1. 📌 Essentials

  • Definition: Progressive buildup of LDL cholesterol-rich fatty deposits in arterial walls forming atheromatous plaques.
  • Affected arteries: Primarily coronary, carotid, peripheral arteries.
  • ** process:** Endothelial dysfunction → fatty streak → fibrous plaque → complicated lesion.
  • Major risk factors: Hypercholesterolemia (>160 mg/dl LDL), hypertension, smoking, diabetes.
  • Plaque stability: Collagen-rich → stable; Lipid-rich → vulnerable/unstable.
  • Critical stenosis: Occlusion >70-75% causes ischemia symptoms.
  • Complications: Plaque rupture → thrombosis → vessel occlusion → infarction.
  • Clinical manifestations: Asymptomatic initially; symptoms arise from chronic ischemia or acute thrombosis.
  • Progression timeline: Begins early in life, becomes symptomatic around ages 35-40.
  • Major outcomes: Chronic ischemia, acute MI, stroke, gangrene.
