Mouse model of post-traumatic stress disorder negatively impacts cardiac homeostasis.

ABSTRACT: Post-traumatic stress disorder (PTSD) is a disabling psychological disorder characterized by chronic symptoms of intrusiveness, avoidance, and hyperarousal after a traumatic event. Retrospective studies have indicated PTSD increases the risk for cardiovascular disease (CVD) including arrhythmia, hypertension, and myocardial infarction. The goal of this study was to: 1) use a murine model of cued fear conditioning (inescapable foot shock, IFS) to develop a scoring method to distinguish a PTSD-like phenotype, and 2) use this model system to characterize the cardiac phenotype and function in mice with extreme PTSD-like behaviors. We compared 3 groups, controls, non-responders (NR), and PTSD-like mice at 2 time points [4-weeks and 8-weeks post-IFS] to compare left ventricular structure and fun
