Study Notes

Definition and Types

  • Arteriosclerosis: a chronic inflammatory response that leads to the thickening and hardening of arterial walls, resulting in reduced blood flow to organs and tissues.
  • Two main types:
    • Atherosclerosis: the most common form, characterized by the buildup of plaque (fatty deposits, cholesterol, and cellular waste) in the inner lining of arteries.
    • Arteriolosclerosis: affects smaller arteries, causing thickening of the vessel wall and narrowing of the lumen.

Causes and Risk Factors

  • Atherosclerosis:
    • High levels of low-density lipoprotein (LDL) cholesterol
    • Smoking
    • High blood pressure
    • Diabetes
    • Obesity
    • Physical inactivity
    • Family history
  • Arteriolosclerosis:
    • Hypertension
    • Diabetes
    • Kidney disease
    • Aging

Pathophysiology

  • Atherosclerosis:
    • Fatty streaks form in the intima (innermost layer) of the artery
    • Inflammation and immune response lead to the formation of plaque
    • Plaque rupture can cause thrombosis, leading to acute coronary syndromes
  • Arteriolosclerosis:
    • Hyaline arteriolosclerosis: deposition of hyaline material in the arteriolar wall
    • Hyperplastic arteriolosclerosis: proliferation of smooth muscle cells and thickening of the vessel wall

Symptoms and Complications

  • Atherosclerosis:
    • Chest pain (angina) or heart attack (myocardial infarction)
    • Stroke or transient ischemic attack (TIA)
    • Peripheral artery disease (PAD)
  • Arteriolosclerosis:
    • Hypertension
    • Kidney disease
    • Retinopathy
    • Cardiovascular disease

Diagnosis and Treatment

  • Diagnostic tools:
    • Imaging techniques (e.g., ultrasonography, angiography, MRI)
    • Blood tests (e.g., lipid profile, blood glucose)
  • Treatment:
    • Lifestyle modifications (e.g., diet, exercise, smoking cessation)
    • Medications (e.g., statins, antihypertensives, antiplatelet agents)
    • Angioplasty or stenting
    • Bypass surgery
