Summary

This study found no significant link between hostility and coronary artery disease in hospitalized patients. Hostility, measured by the Cook-Medley Hostility Inventory, did not predict coronary occlusion, challenging previous findings.

Area of Science:

  • Cardiology
  • Psychosomatic Medicine
  • Behavioral Medicine

Background:

  • Inconsistent findings exist regarding the association between Type A behavior and coronary heart disease (CHD).
  • Hostility, a component of Type A behavior, has been proposed as a potential CHD predictor, but research results are mixed.
  • Previous studies suggest hostility may be a marker for other CHD-related behaviors, necessitating further investigation.

Purpose of the Study:

  • To investigate the predictive power of hostility for coronary occlusion in a population undergoing coronary angiography.
  • To assess the association between hostility, measured via the Cook-Medley Hostility Inventory and the Behavior Pattern Hostility Index, and coronary occlusion.

Main Methods:

  • A study population of 118 men and 40 women scheduled for coronary angiography was recruited.
  • Hostility was assessed using the Cook-Medley Hostility Inventory and the Behavior Pattern Hostility Index.
  • Coronary occlusion was evaluated during coronary angiography; potential coronary risk behaviors were also assessed.

Main Results:

  • No significant positive associations were found between either measure of hostility (Cook-Medley or Behavior Pattern Hostility Index) and coronary occlusion.
  • Observed associations were predominantly in the opposite direction of the hypothesis, though not statistically significant.
  • Replication of cutpoints from previous studies reporting positive associations also yielded null findings.

Conclusions:

  • The study failed to confirm previous reports suggesting a positive association between hostility and coronary artery disease.
  • Hostility, as measured in this study, does not appear to be a significant predictor of coronary occlusion.
  • Further research is needed to clarify the complex relationship between behavioral factors and cardiovascular health.
