Hostility, Coronary Heart Disease, and Ischemia: The Role of Socioeconomic Status

This study investigated (1) the role of SES in the hostility—coronary heart disease (CHD) relationship and (2) the role of socioeconomic (SES) in the hostility— exercise-induced ischemia relationship. One hundred and ninety six patients (101 men and 95 women) were recruited from among patients referred for thallium stress testing. On the basis of their medical history and thallium-stress scans, patients were categorized in the following groups: (1) normal (no CHD or ischemic response, n = 44), 2) Documented CHD (positive thallium scans or previous MI, n = 119), or (3) equivocal ( n = 33). Participants also completed the Hollingshead Index for Social Position, 1 which classified participants as “upper-class” ( n = 27.6%), “middle-class” ( n = 34.7%), or “lower-class” ( n = 37.8%) and the Cook-Medley Hostility (Ho) Scale. 2
