Antagonistic behavior, dominance, hostility, and coronary heart disease

Area of Science:

• Psychosomatic Medicine
• Cardiology
• Behavioral Science

Background:

• Coronary heart disease (CHD) is a leading cause of mortality globally.
• Psychological factors, including hostility and antagonism, are increasingly recognized as contributors to cardiovascular disease.
• Understanding the interplay between behavior and heart health is crucial for prevention strategies.

Purpose of the Study:

• To examine the association between antagonistic behavior, dominance, attitudinal hostility, and the presence of coronary heart disease (CHD).
• To identify specific behavioral components that may confer risk for CHD.
• To explore potential gender differences in the relationship between behavioral factors and CHD risk.

Main Methods:

• 196 participants (101 men, 95 women) undergoing thallium stress testing were assessed.
• The Structured Interview and Cook-Medley Hostility Scale were administered.
• Antagonism was measured by the Hostile Behavior Index, and dominance by interviewer interruptions. CHD status was determined by medical history and stress test results.

Main Results:

• Both the Hostile Behavior Index (antagonism) and dominance were significant independent risk factors for CHD.
• Irritability, a component of the Hostile Behavior Index, showed a significant association with CHD.
• Gender-specific effects were noted: indirect antagonism posed risk for women, while overt anger posed risk for men.

Conclusions:

• Antagonistic behaviors and dominance are significant predictors of coronary heart disease.
• Specific manifestations of antagonism, like irritability, are linked to CHD risk.
• Behavioral risk factors for CHD may differ between men and women, highlighting the need for tailored interventions.
