ATHEROSCLEROSIS

  • ENDOTHELIUM IS DAMAGED
  • INFLAMMATORY RESPONSE, WHITE BLOOD CELLS ACCUMULATE ON ARTERY WALL
  • ATHEROMA  (FATTY STREAKS) ARE FORMED
  • CALCIUM AND FIBROUS TISSUE BUILDS UP AND FORMS A PLAQUE
  • MAKES THE ARTERY WALL INFLEXIBLE AND UNABLE TO PERFORM ELASTIC RECOIL
  • ARTERIES NARROW FURTHER, CREATING HIGH BLOOD PRESSURE
  • MORE CHANCE OF MORE PLAQUES FORMING IN THE FUTURE

CONSEQUENCES

MORE PLAQUES MAY FORM

LEAD TO CORONARY HEART DISEASE (CHD) AND STROKES

BLOCKS THE ARTERY WITH FATTY DEPOSITS
