Several studies have associated the hostility complex (part of type A personality) to the development of coronary atherosclerosis. The complex is composed by aggressive behavior, frequent rage outbursts, intolerance to waiting lines and sense of urgency. To investigate the occurrence of this behavioral trait, 50 post-myocardial infarction men were compared against 50 normal male subjects of the same age. In all of them sphygmomanometric blood pressure was obtained, total blood cholesterol was measured and hostility was quantified by means of the Cook and Medley's questionnaire and an arbitrary ad hoc scale. Diastolic blood pressure was significatively higher in post-infarction patients (82 +/- 10 vs 77 +/- 9, p < 0.001), as well as the cholesterol level (231 +/- 55 vs 197 +/- 43, p < 0.001). Also, hostility score was higher in the post-infarcted men (16 +/- 4 vs 13 +/- 5, p < 0.001). The hostility score showed correlation with the occurrence of myocardial infarction (p < 0.02). These results establish that post-myocardial infarction patients express more hostility than control subjects. It was not possible to establish the true nature of the relationship among hostility and diastolic blood pressure, total cholesterol and the occurrence of coronary events. Nevertheless, this study confirms that the hostility complex is frequently present in atherosclerotic patients.
多项研究已将敌意情结（A型人格的一部分）与冠状动脉粥样硬化的发展联系起来。该情结由攻击性行为、频繁的愤怒爆发、无法忍受排队和紧迫感组成。为了调查这种行为特征的发生率，将50名心肌梗死后男性与50名同龄正常男性受试者进行了比较。对所有受试者都测量了血压，测定了总胆固醇，并通过库克和梅德利问卷以及一个任意的特设量表对敌意进行了量化。心肌梗死后患者的舒张压明显更高（82±10对77±9，p<0.001），胆固醇水平也是如此（231±55对197±43，p<0.001）。此外，心肌梗死后男性的敌意得分更高（16±4对13±5，p<0.001）。敌意得分与心肌梗死的发生率相关（p<0.02）。这些结果表明，心肌梗死后患者比对照组表达出更多的敌意。无法确定敌意与舒张压、总胆固醇和冠状动脉事件发生率之间关系的真正性质。然而，这项研究证实，敌意情结在动脉粥样硬化患者中经常出现。
