hi dear
i am sorry for your accident
coronary artery blockage is a complex phenomenon
many theories have been proposed for it
some of them are
When the arterial endothelium(inner lining of artery) encounters risk factors as diverse as
dyslipidemia, vasoconstrictor hormones invollved in
hypertension, the products of glycoxidation associated with hyperglycemia(
diabetes ), or proinflammatory cytokines derived from excess adipose tissue(obesity), these cells augment the expression of adhesion molecules that promote the sticking of blood
leukocytes to the inner surface of the arterial wall. which in long term is associated with formation of plaques in blood vessels, this process begins at a age of 10 years and progresses with time.
as per your query i am sorry but coronary artery blockage s a result of forces of accuident is not yet proved ,nor there is any article documented that coronary artery blockes as a result of external trauma to the body, however certain conditions like pericarditis(inflammation ) of heart as a result of injury or
pericardial effusion etc can accelerate this process
but direct relation of external trauma to coronary occlusion is yet to be proved
thanks
