Coronary Heart Disease

If a person has a lot of saturated fats in their diet, they run the risk of developing Coronary Heart Disease:

  • Cholesterol (sat-fats) build up on the lining of the coronary artery 
  • The fat narrows the lumen of the artery and redcues blood flow to the heart. This in turn, interferes with oxygen for aerobic respiration. This is a thrombus.
  • Anaerobic respiration is insufficient, so muscles can fatigue and die, including the heart muscle. 
  • The cholesterol build up causes an increase in blood pressure. 
  • The fat build up can califcy and become plaque, which weakens the rtery walls, forming an anuerysm.
  • Atherosclerosis increases tendency of blood clots. In this process, fatty substances called atehroma, become laid down under the endothelial lining of the artery.
