Type A personality traits do not appear to cause cardiovascular disease through abnormal sympathetic responses to stress. This study found no significant differences in stress reactivity among individuals with varying Type A characteristics.

Area of Science:

  • Cardiovascular Physiology
  • Behavioral Medicine
  • Psychosomatic Medicine

Background:

  • Psychosocial factors like Type A personality, anger, hostility, and anxiety are linked to cardiovascular disease.
  • Abnormal sympathetic nervous system responses to stress may mediate this link.
  • Type A personality is characterized by competitiveness, impatience, and aggression.

Purpose of the Study:

  • To test if Type A personality characteristics are associated with exaggerated cardiovascular and sympathetic nerve responses to mental and physical stress in healthy individuals.
  • To investigate the relationship between Type A behavior patterns and physiological stress reactivity.

Main Methods:

  • 45 healthy subjects (19 men, 26 women) without chronic diseases or medications were studied.

  • Heart rate, blood pressure, and muscle sympathetic nerve activity were measured at rest and during stress.
  • Subjects were categorized into tertiles based on Type A personality scores, anger, and cynicism scales.

    • Main Results:

    • No significant differences in sympathetic or hemodynamic reactivity were observed among the three Type A intensity levels.
    • Baseline measures and responses to stress tests were similar across all Type A groups.
    • Sympathetic and hemodynamic changes during stress were also similar when stratified by anger and cynicism scales.

    Conclusions:

    • Sympathetic nerve and hemodynamic measurements at rest and during stress did not differ in normal subjects with Type A characteristics.
    • Abnormalities in sympathetic or cardiovascular reactivity are unlikely to explain excess cardiovascular disease risk in individuals with Type A personality traits.
