The ARIC Study
• Two research arms
–Cohort
–Community morbidity/mortality surveillance

Types of Anger
• Anger experience
–Transitory state (state anger)
–Stable and general predisposition to experience anger (trait anger)

Covariates

Results
• Compared to their low-anger counterparts, persons high in trait anger were more likely to:– be smokers and drinkers– be heavier – have less formal education

Summary
• Overall trait anger was positively associated with risk of both combined CHD and of “hard” events (acute MI/fatal CHD) among normotensive individuals.
![Page 26: Anger and Coronary Heart Disease: Epidemiologic Evidence from the Atherosclerosis Risk in Communities (ARIC) Study Janice E. Williams, PhD, MPH Centers](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d015503460f949d442d/html5/thumbnails/26.jpg)
Summary
• Similarly, trait anger-temperament was positively associated with combined CHD and with “hard” events (acute MI/fatal CHD) among normotensive individuals.
![Page 27: Anger and Coronary Heart Disease: Epidemiologic Evidence from the Atherosclerosis Risk in Communities (ARIC) Study Janice E. Williams, PhD, MPH Centers](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d015503460f949d442d/html5/thumbnails/27.jpg)
Summary
• No statistically significant association was observed between trait anger-reaction and CHD.
![Page 28: Anger and Coronary Heart Disease: Epidemiologic Evidence from the Atherosclerosis Risk in Communities (ARIC) Study Janice E. Williams, PhD, MPH Centers](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d015503460f949d442d/html5/thumbnails/28.jpg)
Conclusions
• A fiery temper predisposes middle-aged normotensive persons to a greater risk of CHD than anger aroused in reaction to frustration, criticism, or unfair treatment.
![Page 29: Anger and Coronary Heart Disease: Epidemiologic Evidence from the Atherosclerosis Risk in Communities (ARIC) Study Janice E. Williams, PhD, MPH Centers](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d015503460f949d442d/html5/thumbnails/29.jpg)
The Mechanism
• High-anger persons, compared to their low-anger counterparts, may be more likely to engage in unhealthy behaviors that place them at risk for CHD.

The Mechanism
• Direct pathophysiological effects via heightened sympathetic arousal and neuroendocrine activation.
