Anger and impatience/irritability in patients of low socioeconomic status with acute coronary heart disease.

This case-control study examines the relationship between anger and impatience/irritability and acute coronary heart disease (CHD) in middle-aged men of low socioeconomic status (SES). Subjects included patients with myocardial infarction (MI) (N = 31) or unstable angina (AP) (N = 26), who were compared with hospital controls (N = 26). In separate multivariate analyses for each anger scale, MI was associated with Anger-Out and Impatience/Irritability, particularly in the subgroup of patients who did not have a previous MI. The same factors were associated with AP, but only when this acute ischemic event was not preceded by a MI. No relationship was found between Trait-Anger and Anger-In and either acute ischemic outcome. The results indicate that particularly overt behavioral expression of anger is related to CHD in lower SES patients and that there is similarity in the behavioral factors associated with acute CHD between low- and high-SES men.
