BB H 432 Lecture 9: Exam 2: Cardiovascular Disease notes
Document Summary
Foods high in trans fat and saturated fat increase serum cholesterol when you eat them. Atherosclerosis = athere (mush) + sclerotic (bony) Cholesterol gets stuck but immune system plays an important role. Good fibrous cap: less likely to rupture. Diet: affects how much cholesterol is there or changes how susceptible the artery is. Arterial susceptibility some people with very high cholesterol may not progress to atherosclerosis. Less dangerous if blood clot is close is ischemic area (may not even know that a heart attack occurred) Angioplasty: use of a balloon to open a blocked artery. Can create a widen channel by pushing plaque back into the walls. Stent: metal structure left in artery to keep it open. Multiple stents can be placed in one procedure. New data have shown that for people who are stable, stents don"t seem to improve cvd risk or quality of life. However, stents for some are a life-saving intervention.
