There are many reasons your doctor may recommend a heart stent. In my case, I had a sore jaw and I noticed that my hand was twitching and was struggling to do what I needed it to do. I had a coronary stent procedure that opened up -- and kept open -- the narrowed places in my heart artery. Here's what I've learned after having a heart stent put in a few years ago, plus what it was like to have an angiogram and angioplasty.
