heart attack
"Had a quintuple bypass surgery in August 2015 following a massive heart attack in May of 2015, during which I "died" for three minutes immediately after arriving at the ER. I had suffered severe chest pain for two hours before going to the ER, which was stupid of me.

I have been on Metoprolol Tartrate for 2.5 years now. 25 mg. twice daily. It seems to work fine, as my blood pressure is consistently around 116 over 64, and my heart rate is 54 BPM at last check-up two months ago. Before my heart attack, it was around 150 over 80, so a vast improvement there. I also am on a low dose (10 mg. daily) of Lisinopril, so that may help as well.

The only side effect I am experiencing is severe exhaustion following a 10-hour shift at work. Age 57."
