Can Anger and Stress Kill?

Andrew Breitbart, a prominent conservative commentator, died yesterday of a suspected heart attack, at only 43 years old. Could the high stress nature of his work and his angry, bombastic persona that made him famous have played a key role in his untimely death? 
Increasing evidence shows that chronic stress can be damaging to our health. However, emotional stress is a normal part of everyone's lives, so doctors and researchers are trying to figure out how and why stress leads to cardiovascular disease for some people. The data suggest that people who struggle to deal with stress in healthy ways are at a higher risk for heart problems. Unhealthy ways to deal with stress include smoking, overeating and anger, according to WebMd.

High levels of anger in young men are linked to developing premature cardiovascular disease. (Symptoms are considered premature if they are diagnosed before age 55.) The exact mechanisms for how anger can lead to cardic disease is unclear, but data suggests that angry people have increased levels of chemicals called catecholamines, as well as elevated heart rates and blood pressure. Research shows that high levels of catecholamines can contribute to the build up of heart- and arter- clogging deposits.
