Hello There, I Am Mostly Looking For Re Assurance About

Question : Hello there, I am mostly looking for re assurance about a stent I had put in recently. Over a week ago I had a heart attack at 35. After performing a XXXXXXX test they discovered that one of my arteries was 80% blocked. They put a stent in to free up the blockage but something has me quite concerned. The stent that was put in blocked off 2 of my side branch arteries. I of course asked the Drs about this and they gave me some assurance but being so young and just starting to recover from the shock of a heart attack I am extremely anxious about all of this. Am I likely to have another heart attack or future heart problems having one of my diagonals 90% blocked off now? Along with another smaller vessel on the other side of my lad? can my heart function properly long term without any flow to these vessels? I included the paperwork I received of before and after the stent. I know nothing can ever be predicted with these things but should I be worried? Thanks so much
