  • 1. ATHEROSCLEROSIS WEEK 4 BIOCHEMISTRY
  • 2. WHAT IS ATHEROSCLEROSIS?
    • Atherosclerosis - is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body.
    • Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries, limiting the flow of oxygen-rich blood to your organs and other parts of your body. This can lead to serious problems, including heart attack, stroke, or even death.

  • 4. ETIOLOGY
    • IDIOPATHIC
    • However, studies show that atherosclerosis is a slow, complex disease that may start in childhood. It develops faster as you age.
  • 5. ETIOLOGY
    • Atherosclerosis may start when certain factors damage the inner layers of the arteries. These factors include:
    • Smoking
    • High amounts of certain fats and cholesterol in the blood
    • High blood pressure
    • High amounts of sugar in the blood due to insulin resistance or diabetes
  • 6. RISK FACTORS
    • Male gender- lack LDL-lowering effect of estrogen
    • Family history/genetics
    • Cigarette smoking- carbon monoxide-induced hypoxic injury to endothelial cells
    • Age
    • Lack of Physical Activity
    • Unhealthy Diet
  • 7. S/SX
    • Atherosclerosis usually doesn't cause signs and symptoms until it severely narrows or totally blocks an artery. Many people don't know they have the disease until they have a medical emergency, such as a heart attack or stroke.
    • Coronary artery- myocardial infarction (heart attack)
    • Cerebral artery- stroke
    • Renal vessels- renovascular HPN
    • Blood vessels of the extremities- gangrene
  • 8. HOW IS ATHEROSCLEROSIS TREATED?
    • Treatments for atherosclerosis may include lifestyle changes, medicines, and medical procedures or surgery.
    • The goals of treatment include:
    • Relieving symptoms
    • Reducing risk factors in an effort to slow or stop the buildup of plaque
    • Lowering the risk of blood clots forming
    • Widening or bypassing plaque-clogged arteries
    • Preventing atherosclerosis-related diseases
