Over the long term, your quality of life is tied to how severe your heart attack was and how it was treated. Beyond that, any change will depend largely on you.

The Framingham risk-assessment tool is used to evaluate a person's risk of heart attack, but it does not consider the influence of inflammation. Researchers have developed a new tool that uses three additional factors to evaluate your heart attack risk.

Discussion of what constitutes a heart attack and new ways to treat them.It’s a story that is played out countless times every day. A 58-year-old man develops chest pain while watching a playoff game on TV. He’s always been pretty healthy, but he hasn’t had a check-up for years. He’s had some heartburn from time to time, but this pain is different: a heavy pressure just below his breastbone with an ache in his jaw. He feels sweaty, nauseated, and a bit lightheaded. Probably the chips and garlic dip, he thinks, reaching for an antacid. But his wife knows better; she calls 911 and gives him an aspirin to chew. The EMTs arrive in a few minutes, but by then the pain is gone. Feeling foolish, he agrees to an IV, oxygen, and a trip to the hospital. In the emergency ward there are questions, EKGs, chest x-rays, and blood tests. And then the big question: Did I have a heart attack?
