Physical and psychological correlates of severe heart disease in men

Area of Science:

• Cardiology
• Psychology
• Behavioral Medicine

Background:

• Coronary artery bypass graft (CABG) surgery patients often exhibit psychological morbidity.
• Understanding the interplay between psychological factors and coronary heart disease (CHD) extent is crucial for comprehensive patient care.

Purpose of the Study:

• To investigate the association between psychiatric morbidity, personality traits, emotional expression, and functional capacity in men undergoing CABG surgery.
• To explore the relationship between psychological measures and the severity of coronary atherosclerosis.

Main Methods:

• Seventy-eight men awaiting CABG surgery were assessed using standardized measures of psychiatric morbidity, personality, and emotional expression (Coping Experiences and Coping Strategies Scale - CECS).
• Functional capacity was evaluated via exercise treadmill time.
• Coronary atherosclerosis severity was assessed angiographically.

Main Results:

• Younger age, shorter symptom duration, and less severe angina were primary predictors of exercise treadmill time.
• Fear expression (measured by CECS) was the only psychological variable significantly associated with atherosclerosis.
• Type A behavior (Bortner score) correlated with exercise capacity but not with CHD indices; its validity is questioned.

Conclusions:

• Emotional expression, particularly fear, shows a significant association with atherosclerosis, suggesting its potential role in CHD.
• The Bortner scale for Type A behavior lacks validity; more robust measures like the CECS are recommended for future research.
• Future studies must account for sex differences and include patients without significant CHD to avoid confounding psychological trait-atherosclerosis relationships.
