My husband had two stents put in the LAD this Jan two years ago. I am told by his supervisor that he changed at work in that he was in a dazz. In July of that same year one of the stents had collapsed and another was placed inside the collapsed stent. Last year in Feb I lost my father to a sudden heart attack, then two weeks later my husband lost a buddy that he played golf with to a sudden heart attack. On March 27th, his best friend whom he worked side by side with for 25 years died of a sudden heart attack. He cry for a solid week. Then on April 11th my husband moved out of our bedroom into our oldest daughter's bedroom. He does not talk to me. He will not talk to his daughters. He is now not talking to his mother or sister. It is like he does not care about his family anymore. My question could the stents in his LAD have caused a chemical imbalance or what is going on? I would love to help him but he will not let me get close to him.
