The metal scaffolding thingy is called stenting and is to allow
the blood vessel to remain intact but complications may occur such
as collapse because of poor surgical skills...
The patient must be on heparin for the rest of his life with this
stenting to prevent thrombus formation on the stent which may spoil
it...
A stent can last up to 10 years but it really depends on which one
that you use, this have to seek a cardiology's opinion...
Yes, the arteries are very flexible... though they are more
muscular than veins and has smaller lumens, but they are flexible
enough to pump the blood to the peripheral organs...
During a heart attack, the heart will go static, or more rather go
into an arrhythmic condition (beating out of rhythm or not in
rhythm with the natural pacemaker)... when the heart is in the
arrhythmic condition, it fails to pump effectively and blood in the
heart pools up and may even go all the way back towards the lung
(recall anatomy) in severe acute condition...
Ermm... breathing deeply won't help that much, the best method is
to carry out CPR and get someone to call the ambulance to initiate
Code Red in the A/E dept of the particular hospital...
Basic Life Support must be initiated no matter what, recall your DR
ABC...
(Danger Response Airway Breathing Circulation)
...while waiting for Advance Life Support...
