The writings/articles/scribbles are my collection of what is stumbled or read somewhere on the net (I try to give credit where it is due). Most of the time I forgot where I read something, hopefully this will compile all those in one site and along the way we hope not to compromise or infringe any law.

in the Coronary Care Unit CCU after Angioplasty
http://en.wikipedia.org/wiki/Angioplasty
Angioplasty is the technique of mechanically widening narrowed or obstructed arteries, the latter typically being a result of atherosclerosis. An empty and collapsed balloon on a guide wire, known as a balloon catheter, is passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure (6 to 20 atmospheres). The balloon forces expansion of the inner white blood cell/clot plaque deposits and the surrounding muscular wall, opening up the blood vessel for improved flow, and the balloon is then deflated and withdrawn. A stent may or may not be inserted at the time of ballooning to ensure the vessel remains open.
