title: Association of acute coronary syndrome-induced posttraumatic stress disorder symptoms with self-reported sleep.
abstract: BACKGROUND
  Symptoms of posttraumatic stress disorder (PTSD) after acute coronary syndrome (ACS) are associated with recurrent ACS events and mortality. Poor sleep may be a mechanism, but the association between PTSD and sleep after ACS is unknown.
  
  
  OBJECTIVE
  This study aims to estimate the association between ACS-induced PTSD symptoms and self-reported sleep.
  
  
  METHODS
  ACS-induced PTSD symptoms were assessed 1-month post-ACS in 188 adults using the Impact of Events Scale-Revised. Sleep was assessed using the Pittsburgh Sleep Quality Index. Linear and logistic regression models were used to determine whether PTSD symptoms were associated with self-reported sleep, independent of sociodemographic and clinical covariates.
  
  
  RESULTS
  In adjusted models, ACS-induced PTSD symptoms were associated with worse overall sleep (β = 0.22, p = 0.003) and greater impairment in six of seven components of sleep (all p values <0.05).
  
  
  CONCLUSIONS
  ACS-induced PTSD symptoms may be associated with poor sleep, which may explain why PTSD confers increased cardiovascular risk after ACS.
