Components of hostility and the severity of coronary artery disease.

Previous research has linked various measures of hostility to the prevalence and incidence of coronary heart disease (CHD). The present study sought to determine whether some dimensions of hostility are differentially related to angiographically documented severity of coronary artery disease (CAD). Specifically, a hostility measure that correlates with indices of neuroticism was compared with a hostility measure unrelated to neurotic tendencies. For patients 60 years and younger, results were significant, revealing that neurotic hostility was inversely associated with severity of CAD whereas nonneurotic hostility scores were positively related to extent of disease. Overall hostility scores derived from the combination of the two kinds of hostility measures were unrelated to CAD severity. Results suggest that the multidimensional nature of the hostility construct should be appreciated in attempts to associate measures of hostility with manifestations of CHD.

Expressive vocal behavior and the severity of coronary artery disease.

This study sought to ascertain the relationship of expressive vocal behavior in a structured interview and the severity of coronary artery disease in a group of 79 patients referred for coronary angiography. One half of the structured interview was administered in a nonchallenging manner, the other half in a moderately challenging manner. In patients age 60 and younger, two speech measures derived from the nonchallenging interview, a computer-scored index of the frequency of simultaneous speech and judged loudness level, accounted for 38% of the variance in the patients' severity of stenosis scores, when the latter was indexed by the Gensini method. The same speech indices derived from the challenging interview segment accounted for only 18% of the variance on the patients' Gensini scores. In the older patient group, only one speech variable, speech rate in the nonchallenging interview segment, contributed to the patients' Gensini scores. The findings suggest a) that in younger patients objective, computer-scorable, speech variables correlate significantly with severity of coronary occlusion, and b) that is not essential that these speech indices be derived from a structured interview that is administered in a challenging and provocative manner. In the present study, there were no significant correlations between the participants' global TABP scores and their occlusion scores.

The angry voice: its effects on the experience of anger and cardiovascular reactivity.

The results of two studies show that expressive vocal behavior, specifically, speech rate and loudness, influences the experience of anger and cardiovascular reactivity. In both studies, participants spoke about anger-arousing and neutral events using three different voice styles: fast and loud, slow and soft, and normal (personal rate and loudness level). In describing the anger-arousing events, both male and female participants reported feeling significantly more angry and showed significantly greater blood pressure and heart rate reactivity in the fast-loud compared with the normal speaking condition. They also reported feeling significantly less angry and showed significantly lower blood pressure reactivity in the slow-soft compared with the normal voice condition. For males only, the voice manipulation also had significant effects on the participants' anger self-ratings and cardiovascular responses during the neutral communications, but these effects were clearly weaker and less pervasive than those occurring during the angry communications. The results are discussed in terms of their implications for (1) the role of expressive vocal behavior in emotions, and (2) the modification of coronary-prone behavior.

Antagonistic behavior, dominance, hostility, and coronary heart disease.

PURPOSE: This study investigated the relationship between antagonistic behavior, dominance, attitudinal hostility, and coronary heart disease (CHD). METHODS: One hundred one men and 95 women referred for thallium stress testing were administered the Structured Interview and the Cook-Medley Hostility Scale. The Hostile Behavior Index, derived from the Structured Interview and developed by Haney et al., served as an index of antagonism, and the frequency with which interviewees interrupted their interviewer served as a measure of dominance. On the basis of their medical history and thallium stress test results, patients were classified as having (N = 44) or not having (N = 99) CHD. RESULTS AND CONCLUSIONS: Multivariate logistic regressions (with age, gender, disease, and lifestyle risk factors in the model) revealed that both the Hostile Behavior Index and dominance were significant independent risk factors for CHD (relative risk [RR] = 1.22 and 1.47, p < .03). Of the two Hostile Behavior Index component scores, indirect challenge and irritability, only the latter correlated significantly with CHD (RR = 1.27, p < .03). Separate logistic regressions for men and women suggest that subtle, indirect manifestations of antagonism confer CHD risk in women and that more overt expressions of anger confer risk in men. A significant univariate correlation between hostility scale scores and CHD became not significant when we adjusted for socioeconomic status.
