I found this article, which is relavant to men and some women of 50 yrs or older. Not a Moment Too Soon, I Thought of Tim Russert Tim Russert, a well-known TV journalist died suddenly of a heart attack at the young age of 58. He was being treated for some heart/coronary disease, but when he died it came on suddenly without warning. Edit: I changed the title to "Early warning signs of heart attack", from "Asypmtomatic heart attack" to be more accurate. As is pointed out, some symptoms may be associated with other ailments and people may too often dismiss them. Russert apparently didn't know he was about to have a massive heart attack.
