Learned helplessness reveals a population at risk for depressive‐like behaviour after myocardial infarction in mice

Aims Myocardial infarction (MI) and heart failure (HF) are risk factors for the development of depression, additionally worsening the quality of life and patient outcome. How HF causes depression and how depression promotes HF remain mechanistically unclear, which is at least partly caused by the difficulty of in vivo modelling of psychosomatic co‐morbidity. We aimed to study the potential sequence of events with respect to different depression aspects upon HF.
