目的：我们检验了一种假设，即控制知觉可以调节急性心肌梗死（AMI）患者的焦虑与院内并发症（即复发性缺血、再梗死、持续室性心动过速或纤颤以及心源性死亡）之间的关系。背景：焦虑在AMI患者中很常见，但它是否与较差的预后相关仍有争议。关于焦虑与心脏发病率和死亡率关系的相互矛盾的发现可能是由于未能考虑感知控制的调节作用。方法：对536例AMI住院患者的焦虑、感知控制和随后的院内并发症之间的关系进行前瞻性研究。结果：患者的平均焦虑水平是公布的平均标准的两倍。感知控制水平较高的患者焦虑程度显著降低（p = 0.001）。共有145例（27%）患者出现了一种或多种院内并发症。焦虑水平较高的患者发生室性心动过速、心室颤动、再梗死和缺血的次数明显增加
Objectives: We tested the hypothesis that perception of control moderates any relationship between anxiety and in-hospital complications (i.e., recurrent ischemia, reinfarction, sustained ventricular tachycardia or fibrillation, and cardiac death) in patients with acute myocardial infarction (AMI). Background: Anxiety is common among patients with AMI, but whether it is associated with poorer outcomes is controversial. Conflicting findings about the relationship of anxiety with cardiac morbidity and mortality may result from failure to consider the moderating effect of perceived control. Methods: This was a prospective examination of the association among anxiety, perceived control, and subsequent in-hospital complications among patients (N = 536) hospitalized for AMI. Results: Patients' mean anxiety level was double that of the published mean norm. Patients with higher levels of perceived control had substantially lower anxiety (p =.001). A total of 145 (27%) patients experienced one or more in-hospital complications. Patients with higher levels of anxiety had significantly more episodes of ventricular tachycardia, ventricular fibrillation, and reinfarction and ischernia (p
