    The Type A behavior pattern, characterized by competitiveness and hostility, is linked to more severe coronary atherosclerosis. This association persists even when accounting for traditional risk factors like age and cholesterol.

    Area of Science:

    • Cardiology
    • Psychosomatic Medicine
    • Behavioral Medicine

    Background:

    • Previous studies linked Type A behavior pattern to increased clinical coronary heart disease (CHD) events.
    • The relationship between Type A behavior and the underlying coronary atherosclerotic process required further investigation.

    Purpose of the Study:

    • To determine if the association between Type A behavior and CHD extends to the coronary atherosclerotic process.
    • To assess the correlation between behavior patterns and the severity of coronary atherosclerosis.

    Main Methods:

    • 156 patients undergoing coronary angiography were assessed using a structured interview for behavior pattern (Type A, Type B, Type X).
    • Coronary atherosclerosis severity was evaluated, and traditional risk factors (age, sex, cholesterol, smoking) were recorded.

    Main Results:

    • Traditional risk factors like age, sex, cholesterol, and smoking correlated with atherosclerotic disease.
    • Type A patients showed increasing proportions with moderate to severe coronary occlusions.
    • This association remained significant after controlling for traditional risk factors.

    Conclusions:

    • Behavior pattern Type A independently contributes to the risk of coronary heart disease.
    • Type A behavior may influence the atherosclerotic process, increasing the risk of clinical CHD events.
