I had a heart attack 1 year ago and had a stent fitted at the time, and another in Jan 2015. Still have 1 artery at 75% blocked but as heart pump test was 50% no further stents were fitted. On the usual tablets except statin as also have pbc. Recently I've had missed or extra heartbeats. I mentioned it to gp and he took my pulse and said it was fine. About 2 weeks ago I had a day when it was lasting most of the day, no pain just really irregular. It was sunday and I decided to wait until Monday and if no change phone my cardiac nurse. By Monday it was fine. Just wondered if anybody had this, leading to a heart attack? I know stress can do this but really don't feel that and also don't feel like I'm paying too much attention to heartbeats . Still occasionally have them but never any pain.Just a bit worried that the clogged artery is getting worse, or is it too close to my last check in January (8 months ago) to have changed a lot?
