Abstract

WENNEBERG and colleagues, Maharishi University of Management, Fairfield, Iowa USA studied the relationships between increased platelet aggregability and the psychological traits hostility and anger.

Background

Methodology

This study was part of a larger intervention study investigating the potential efficacy of stress reduction techniques. Study participants performed 6-minute mental arithmetic tests under time pressure. Blood was taken during the first minute and whole blood platelet aggregation measured. Anger and hostility were assessed using Spielberger's State-Trait Anger, Anger Expression and Cook-Medley Hostility scales.

Results

There were positive correlations between collagen-induced platelet aggregation and outwardly expressed anger, as measured by the Anger Expression Scale. These results suggested that modes of anger expression may be association with increased platelet aggregation.

Conclusion

These findings may provide a mechanism for the putative connection between anger/hostility and coronary heart disease.
