CORRECT ANSWERS!!

What is CAD (coronary artery disease)?

Narrowing of the coronary arteries limits blood supply to the heart muscle causing
angina

-is a deposit of fatty tissue that hardens over time

development of CAD

1. fatty streaks on the vessel wall

2. raised fibrous plaque that starts to constrict blood flow

3. complicated lesions that create RBC traffic jams




Plaque rupture

when the covering of the plaque opens exposing the underlying plaque

can be due to a change in biochemistry or blood flow



Thrombosis

The plaque ruptures and the lipid core begins to hemorrhage. platelets collect and a
thrombus forms



occlusion of the artery

Obstruction or narrowing of an artery leading to reduced blood flow
