Angioplasty

I resently had an angioplasty to correct a 90% blockage.  My cardiologist told me that dispite the blockage, I was at low risk for an MI at this time.  How can that be?  Also, the balloon
broke during the procedure, tearing the artery.  A second stint had to be placed in the artery.  Does this happen often?  What can cause the balloon to break?  Will I have any increased risks
with the second stint.  The artery is now open and my Cardiologist tells me I did myself a favor in the prevention area.
Thanks

tech,

Thanks for the post. Having coronary disease certainly puts you in a category for a risk of a coronary event greater then the general population.  

While noone can completely see the future, there are some ways to predict your overall risk. These factors would include your ability to exercise or do you daily activities without symptoms, your cholesterol, your smoking status, and your CRP. The latter is a test that reflects how active the inflammation causing your coronary blockages is.

All of the factors you can modify you should strive to do so.

Complications during angioplasty and stenting are not common, but they certainly are not rare. Most of the times the complications can be fixed by the person performing the procedure. Dissection (the tear) is one of the more common ones, these can be severe enough to need surgical coorection, but most of the time can be fixed by the cardiologist performing the procedure.
