Hostility in asymptomatic men with angiographically confirmed coronary artery disease

Area of Science:

• Cardiology
• Psychosomatic Medicine
• Epidemiology

Background:

• Coronary artery disease (CAD) is a leading cause of mortality worldwide.
• The role of psychological factors, such as hostility, in CAD pathogenesis requires further investigation.
• Aircrew members offer a unique cohort for studying cardiovascular disease due to structured health monitoring.

Purpose of the Study:

• To investigate the association between hostility and coronary artery disease in a sample of asymptomatic aircrew members.
• To explore potential interactions between hostility and other cardiovascular risk factors, specifically smoking.

Main Methods:

• A case-control study design was employed.
• Participants were referred for coronary angiography based on noninvasive tests or risk factor status.
• Hostility was assessed through behavioral observations during a standard interview; self-reported hostility was also measured.

Main Results:

• Cases with coronary artery disease (n=24) exhibited higher hostility scores than controls (n=25) among non-smokers (p=0.004).
• This association between hostility and CAD was not observed in smokers.
• Self-reported hostility did not differentiate between cases and controls.

Conclusions:

• Observed hostility, not self-reported, is associated with coronary artery disease in non-smokers.
• Findings suggest an interaction between hostility and smoking in the development of coronary atherosclerosis.
• Hostility may be a significant factor in the pathogenesis of cardiovascular disease, particularly when interacting with other risk factors.
