Evidence supports the contribution of depression, anxiety, and poor social support to mortality of hospitalized myocardial infarction (MI) patients. The contribution of depression to survival is independent of disease severity. Pet ownership, a non-human form of social support, has also been associated with one year survival of post-MI patients. The current study addresses whether pet ownership contributes independently to long term survival beyond the contributions of depression, anxiety, or low social support in post-MI patients who have already survived at least 6 months. Data from patients (N = 460) enrolled in the "Psychosocial Responses in the Home Automated External Defibrillator Trial (PR-HAT)"were used. Seventeen patients died during a median follow-up of 2.8 years. In Cox proportional hazards regression model that included depression, lack of pet ownership, and the interaction between depression and lack of pet ownership, not owning a pet was the only significant independent predictor of mortality (p = 0.036). The interaction between pet ownership and depression tended to be significant indicating that the effect of pet ownership on survival in this group of people who have supportive spouses/companions living with them may relate to depression.
有证据表明，抑郁、焦虑和社会支持不足会影响住院心肌梗死（MI）患者的死亡率。抑郁对患者生存的影响独立于疾病严重程度。养宠物作为一种非人类形式的社会支持，也与心肌梗死后患者的一年生存率相关。本研究探讨在至少已存活6个月的心肌梗死后患者中，养宠物是否能在抑郁、焦虑或社会支持不足之外，独立对长期生存产生影响。研究采用了“家庭自动体外除颤器试验的心理社会反应（PR-HAT）”中460名患者的数据。在中位随访2.8年期间，有17名患者死亡。在包含抑郁、未养宠物以及抑郁与未养宠物之间相互作用的Cox比例风险回归模型中，未养宠物是唯一显著的死亡率独立预测因素（p = 0.036）。养宠物与抑郁之间的相互作用趋于显著，这表明在有支持性配偶/伴侣陪伴的人群中，养宠物对生存的影响可能与抑郁有关。
