It is shown that people who are "chronically angry and hostile have a greater likelihood for heart attack, people who "live in anxious, stressed out lifestyles have greater blockages of their coronary arteries", and people who are "chronically depressed have a two times greater change of heart disease. According to a 2006 article on WebMD, studies at the University of Maryland found that when a group of people were shown a comedy, after the screening their blood vessels performed normally, whereas when they watched a drama, after the screening their blood vessels tended to tense up and restricted the blood flow.
