Prayer Request

Hey guys, could y'all please be praying for my cousin Richard? He is 20 years old and had a massive heart attack on Friday. The doctors say that he is going to be fine and his heart was not damaged, but they can't figure out why he had the attack. Hospitals have a test they can administer to determine if someone has a heart attack and a normal person who hasn't will score a 0 or 1, Richards came back as a 28. My aunt was told that normally only young people on cocaine have heart attacks like this, but Richard doesn't do drugs and when the doctors tested him he was completely clean and there was absolutely no evidence he had ever done drugs at all. His cholesterol and blood pressure were really good too. There doesn't appear to be any reason what so ever that he should have had this massive attack. I don't think he's a Christian, so please pray for him. Thanks!!
