Components of the Anger-hostility Complex as Risk Factors for Coronary Artery Disease Severity: A Multi-measure Study

Area of Science:

• Cardiology
• Psychosomatic Medicine
• Behavioral Medicine

Background:

• Anger and hostility are linked to coronary artery disease (CAD) pathogenesis.
• Previous research has not comprehensively assessed various anger/hostility forms in a single study.
• Understanding the specific roles of different anger expressions is crucial for CAD etiology.

Purpose of the Study:

• To evaluate the relative predictive utility of multiple anger and hostility measures in relation to CAD.
• To identify which specific anger/hostility variables are most significantly associated with coronary artery disease.
• To guide future research by pinpointing key etiological factors in CAD.

Main Methods:

• A multi-measure study involving three adult outpatient groups.
• Participants included men with angiographically confirmed CAD, men with valvular heart disorders, and men attending a fracture clinic (no CAD).
• Questionnaires assessed anger expression, anger experience, cynical hostility, 'Ho' hostility, neurotic hostility, neurotic disagreeableness, resentment, and suspiciousness.

Main Results:

• Expressed anger emerged as the most significant correlate of CAD.
• Years as a smoker and advanced age were also independently related to CAD severity.
• Seven other anger/hostility variables showed no significant predictive utility comparable to expressed anger.

Conclusions:

• Expressed anger is a primary anger-hostility correlate in coronary artery disease etiology.
• Further investigation is needed to identify the specific toxic components of expressed anger and relevant socio-occupational environments.
• Research should focus on the mechanisms linking expressed anger to CAD and contextual factors influencing its occurrence.
