Stress cardiomyopathy (SCM) can be triggered by emotional events. Recently, type D personality has been established as an independent predictor of acute cardiac adverse events.
We sought to examine whether type D personality can be identified in SCM patients.
A case-control study with 37 SCM patients, 37 myocardial infarction (AMI) patients, who both experienced emotional triggering, and 37 SCM patients without emotional triggers was performed. The DS14 and Interview for Recent Life Events were administered.
Twenty-eight (76 %) SCM emotional trigger patients were categorized as type D compared with 13 (43 %) SCM patients without emotional trigger and 12 (32 %) AMI patients (p < 0.001). SCM patients with emotional triggers had higher scores on the social inhibition subscale than the other patient groups.
The present study highlights the possible link between type D, with a specific key role for social inhibition component, and increased biological reactivity to acute emotional stress.
应激性心肌病（SCM）可由情绪事件引发。最近，D 型人格已被确定为急性心脏不良事件的独立预测因子。
我们旨在研究 D 型人格是否可在 SCM 患者中识别。
采用病例对照研究，纳入 37 例 SCM 患者（有情绪诱因）、37 例心肌梗死（AMI）患者（有情绪诱因）和 37 例无情绪诱因的 SCM 患者。采用 DS14 和近期生活事件访谈进行评估。
28 例（76%）有情绪诱因的 SCM 患者被归类为 D 型，而 13 例（43%）无情绪诱因的 SCM 患者和 12 例（32%）AMI 患者为 D 型（p<0.001）。有情绪诱因的 SCM 患者在社会抑制分量表上的得分高于其他患者组。
本研究强调了 D 型人格与对急性情绪应激的生物学反应增强之间可能存在关联，且社会抑制成分可能起关键作用。
