type A behavior

 
a behavior pattern associated with the development of coronary heart disease, characterized by excessive competitiveness and aggression and a fast-paced life style. Persons exhibiting type A behavior are constantly struggling to accomplish ill-defined goals in the shortest possible time. In several studies this type of behavior has been shown to be as significant as other risk factors, such as smoking and hypertension, in the development of coronary artery disease and myocardial infarction. The opposite type of behavior exhibited by individuals who are relaxed, unhurried, and less aggressive is called type B.
