Suggest Treatment For Chest And Arm Pain While On Aspirin

My husband is 57 yr old and about 3 weeks ago on a Sunday he was woke up at about 5:00 Am with Dom chest pain , arm pain. He thought he might be having a heart attack. By the I got up he had taken a aspirin and a blood pressure pill and said he felt.a litter better and did not want to go. On the following Wednesday he went to the Dr they sent him over to see the heart dr and on the following Friday he had a artergram and they put 2 stents and now he goes off at little things. Today my granddaughter called and wanted to spend the night and have 2 friends over , she has done that several times, and it has never been a problem. When she ask I had gone to the kitchen and told my husband that she was spending the night with a friend he did not say anything. When she came over about 45 min later , after they went into the bedroom where they watch tv and stuff he went off on me , he said I did not tell him he was so mad you cou,d see it in his eyes he was mad. I to,d him I did tell him her argoured I did not tell him. I said I did but maybe he did not heR me. Is this normal after having heart stents put in ???
