Participants consisted of 184 patients (160 males, 24 females) with positive angiograms or prior myocardial infarctions who displayed at least 1 mm of ST segment depression on a standardized treadmill test. Mean scores on the Reward Dependence subscale of the Tridimensional Personality Questionnaire were higher in patients displaying ischemia during mental stress. Patients who reported higher levels of irritability/anger in response to the Speech stressor were also more likely to display ischemia. However, this result was primarily a result of the females in the sample whose ratings of interest and irritability were associated with ischemia during the Speech task. Psychometric measures previously found in prospective studies to predict acute cardiac events were unrelated to mental stress-induced ischemia in the laboratory.
参与者包括 184 名患者（160 名男性，24 名女性），他们的血管造影或先前的心肌梗死呈阳性，并且在标准化的跑步机测试中显示至少 1 毫米的 ST 段压低。在精神压力下显示缺血的患者在三维人格问卷的奖励依赖分量表上的平均得分更高。对言语应激源反应报告更高水平的易怒/愤怒的患者也更有可能显示缺血。然而，这一结果主要是由于样本中的女性，她们的兴趣和易怒评分与言语任务期间的缺血有关。以前在前瞻性研究中发现的预测急性心脏事件的心理测量指标与实验室中精神压力引起的缺血无关。
