The hostility complex, a component of Type A personality, is more prevalent in men who have experienced myocardial infarction. This behavioral trait is linked to increased risk of coronary atherosclerosis.

Area of Science:

  • Cardiology
  • Psychology
  • Behavioral Medicine

Background:

  • The hostility complex, characterized by aggression and impatience, is linked to coronary atherosclerosis.
  • Type A personality traits are increasingly recognized for their impact on cardiovascular health.

Purpose of the Study:

  • To compare hostility levels in men post-myocardial infarction versus healthy controls.
  • To investigate the association between hostility and cardiovascular risk factors.

Main Methods:

  • Compared 50 post-myocardial infarction men with 50 age-matched healthy male subjects.
  • Measured blood pressure, total cholesterol, and quantified hostility using standardized questionnaires.
  • Utilized sphygmomanometric measurements and the Cook and Medley questionnaire for hostility assessment.

Main Results:

  • Post-myocardial infarction patients exhibited significantly higher diastolic blood pressure (82 vs 77 mmHg) and total cholesterol (231 vs 197 mg/dL).
  • Hostility scores were significantly elevated in the post-myocardial infarction group (16 vs 13).
  • Hostility scores correlated with myocardial infarction occurrence (p < 0.02).

Conclusions:

  • Post-myocardial infarction patients demonstrate higher levels of hostility compared to control subjects.
  • The hostility complex is a common trait among patients with coronary atherosclerosis.
  • Further research is needed to clarify the direct relationship between hostility, blood pressure, cholesterol, and coronary events.
