Should I Continue Taking Plavix And Metropolol Given My History Of Heart Issues And Peripheral Vascular Disease In My Leg?

Hello. I am diabetic; My AIC is about 6.7. I take metformin, 500 mg, twice/day. I have MS; I have trouble walking due to footdrop. I had a heart attack in January 2017 due to blockages. I now have 4 stents. I had congestive heart failure in March 2017. I have been taking 75 mg of Plavix and 25 mg of metropolol since the heart failure. Since the heart failure, I lost 40 lbs (I am 6 tall, I went from 230 to 185-190), and I exercise. My heart is stronger than it used to be, ejection fraction is consistently 60 to 65. I have peripheral vascular disease in my leg. Should I keep taking the plavix and metrpolol?
