Cardiac Catheterization, how's your perspective on it, experience?

I had a Cardiac Cath 2 years ago, went to E.R. just was feeling "weird" well turned out I was having a heart attack, I was rushed to the Cath Lab & had 2 stents put in LAD, the Cath I barely remember, I must have been put under conscious sedation, I have to take heart med. & blood thinners forever, I have damage to my heart, I feel my heart skips a beat off and on now, but I made it! Good luck w/ your project.
