[Relationship between type A behavior and the other risk factors in chronic disease].

The relationship between psychological features and coronary heart disease (CHD) have long been investigated. Type A behaviour consists of psychological, behavioral and cognitive features and represents an important risk factor for CHD. The present report is a review of the international literature on the subject. In particular we have taken into account the relationships among type A and other risk factors and the possible biological mechanisms through which type A behaviour may promote CHD.
