Transcript of "Atherosclerosis"

  1. 1. ATHEROSCLEROSIS WEEK 4 BIOCHEMISTRY
  2. 2. WHAT IS ATHEROSCLEROSIS? <ul><li>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. </li></ul><ul><li>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. </li></ul>
  3. 3. ATHEROSCLEROSIS
  4. 4. ETIOLOGY <ul><li>IDIOPATHIC </li></ul><ul><li>However, studies show that atherosclerosis is a slow, complex disease that may start in childhood. It develops faster as you age. </li></ul>
  5. 5. ETIOLOGY <ul><li>Atherosclerosis may start when certain factors damage the inner layers of the arteries. These factors include: </li></ul><ul><li>Smoking </li></ul><ul><li>High amounts of certain fats and cholesterol in the blood </li></ul><ul><li>High blood pressure </li></ul><ul><li>High amounts of sugar in the blood due to insulin resistance or diabetes </li></ul>
  6. 6. RISK FACTORS <ul><li>Male gender- lack LDL-lowering effect of estrogen </li></ul><ul><li>Family history/genetics </li></ul><ul><li>Cigarette smoking- carbon monoxide-induced hypoxic injury to endothelial cells </li></ul><ul><li>Age </li></ul><ul><li>Lack of Physical Activity </li></ul><ul><li>Unhealthy Diet </li></ul>
  7. 7. S/SX <ul><li>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. </li></ul><ul><li>Coronary artery- myocardial infarction (heart attack) </li></ul><ul><li>Cerebral artery- stroke </li></ul><ul><li>Renal vessels- renovascular HPN </li></ul><ul><li>Blood vessels of the extremities- gangrene </li></ul>
  8. 8. HOW IS ATHEROSCLEROSIS TREATED? <ul><li>Treatments for atherosclerosis may include lifestyle changes, medicines, and medical procedures or surgery. </li></ul><ul><li>The goals of treatment include: </li></ul><ul><li>Relieving symptoms </li></ul><ul><li>Reducing risk factors in an effort to slow or stop the buildup of plaque </li></ul><ul><li>Lowering the risk of blood clots forming </li></ul><ul><li>Widening or bypassing plaque-clogged arteries </li></ul><ul><li>Preventing atherosclerosis-related diseases </li></ul>
