LDL transports cholesterol to cells
HDL transports cholesterol to liver
LDL + cholesterol can form thrombus = clot
Hemorheologic–hemodynamic theory:
Slowed blood flow = mechanism for cholesterol buildup on arterial walls
Acute Myocardial Infarction (AMI)Delivery of oxygen by the coronary arteries
LESS THAN
Oxygen demand of the myocardial cell
~ 200-250 ml/min
Excercising
200 ml/minRest
Exercise 1000 ml/min~ 1000 ml/min
NORMAL
Myocardium uses > 75% of oxygen delivered to it!!!!!!!
Acute Myocardial Infarction (AMI)Delivery of oxygen by the coronary arteries
LESS THAN
Oxygen demand of the myocardial cell
~ 200-250 ml/min
Blockage of coronary = reduced flow….but there is no margin for reduced flow
