I had a stent put in about 8-9 years ago. My right coronary artery was 95% blocked. Immediatley after, they put me on Lipitor, Toprol and Plavix. That remained the same until I moved from NY back to MN.
Since I moved back to MN, I've been going to get my blood drawn and visiting the doc about every 3-4 months. They've changed my meds and doses regularily. I can't even remember what all I take now but there's a staten, a blood thinner, a beta blocker, SloNiacin, Fish Oil and something else i think.
My total Cholesterol is good and has been for quite a while but my HDL never seems to move up to where it's supposed to be. My triglycerides went from over 600 at the time of my stent to now under 200.
I eat a reasonably low fat, low cholesterol, low sugar diet. I met with a dietition and she really couldn't find anything in my diet to correct. I exercise most days.
I guess people react differently to different meds, thus all the experimentation and trial and error I've been through the past few years with this. My Dr. is really intent on getting all my numbers fixed even if it kills one of us.
[EDIT] BTW, I get those fluttering sensations in my chest too. It's an arythmia in the upper heart chamber and that's what the beta blockers are for. Both the Doc in NY and the one in MN say it's nothing to worry about.
