The last week I've been experiencing tension and fluttering intermittently around my heart at night. My pulse and bp are 55 and 125/86. I'm a runner who had a stent placed in my left coronary descending artery July 2013. It is a bare metal stent. I am type one diabetic too (A1C of 7.1), last check. I take 75 mg clopigogrel, 12.5 mg metrol tartrate, and baby aspirin in the morning. I take 10 mg lisinprol, 1000 units fish oil, 100 mg COQ10, and 12.5 mg metrol tartrate at night. I am pain free and energetic. Any suggestions?
