Hopelessness and Depression in Myocardial Infarction

描述（由申请人提供）：冠心病（CHD）和抑郁症是高度流行和共病的公共卫生问题，导致大量过高的发病率和死亡率。绝望与患有身体疾病的人的抑郁密切相关，并且已被确定为许多疾病发病率和死亡率增加的重要预测因素。然而，很少有研究描述心肌梗死后恢复期绝望症状的患病率、严重程度和影响。本研究的总体目的是描述心肌梗死后的绝望和抑郁症状，以及描述心肌梗死后绝望症状、心脏康复运动依从性和身体功能之间的关系。该项目的具体目的是：(1)描述出院后3个月心肌梗死后患者绝望症状和抑郁症状的患病率和严重程度；(2)描述出院后3个月心肌梗死后患者绝望症状、心脏康复运动依从性和身体功能之间的关系。本研究将为博士后护理干预研究奠定基础，重点研究结构化行为策略，以预防心肌梗死后绝望和抑郁症状，并促进经历绝望和/或抑郁症状的心肌梗死患者的心脏康复运动坚持性和最佳身体功能。

DESCRIPTION (provided by applicant): Coronary heart disease (CHD) and depression are highly prevalent and co-morbid public health problems that result in substantial excess morbidity and mortality. Hopelessness has been well associated with the presence of depression in individuals with physical illness, and has been identified as an important predictor of increased morbidity and mortality in a number of illnesses. However, little research has been done to describe the prevalence, severity, and impact of hopelessness symptoms among people in the post-myocardial infarction (MI) recovery period. The overall purpose of the proposed research is to describe symptoms of hopelessness and depression following an MI, and to describe the relationships among hopelessness symptoms, cardiac rehabilitation exercise adherence, and physical functioning post-Ml. Specific aims of the proposed project are: (1) to describe the prevalence and severity of hopelessness symptoms and depressive symptoms among post-MI patients at 3 months after hospital discharge, and (2) to describe the relationships among hopelessness symptoms, cardiac rehabilitation exercise adherence, and physical functioning in post- MI patients at 3 months after hospital discharge. This study will be foundational for developing a program of nursing intervention research postdoctorally, focusing on structured behavioral strategies to prevent symptoms of hopelessness and depression post-MI and to promote cardiac rehabilitation exercise adherence and optimal physical functioning of the MI patient who is experiencing hopelessness and/or depressive symptoms.
