According to them, there is a personality type, A , that predisposes to heart problems . Individuals who have it are very impatient and show great urgency in everything. They like things to be done quickly, they are obsessed with being on time, and they get irritated when they are delayed. They move, walk and eat quickly; They speak fast and are very time conscious: they like to set deadlines and stick to them. They tend to be competitive at work and at leisure. They always play to win, even if the rivals are children or friends.

The type A individual performs various unconscious physical actions to release tension: blinking, drumming with fingers, moving knees … They are people who try to multitask, are easily irritated by people or events, and They show anger when they relate past events that caused them outrage.

The relationship between this hostility and the risk of cardiovascular disease has been confirmed by many subsequent studies, but therapists know that helping to change these subjects is difficult, because type A behavior is associated in our society with professional prestige , high income and job promotion, in short, to the stereotype of the winner .
