title: Psychological factors and coronary heart disease.
abstract: BACKGROUND
  Although psychological factors play an important role in coronary heart diseases (CHD), it seems there is a need for more researches in this respect. The present study aimed to review psychological factors, including depression, anxiety and stress related to etiology and prognosis of CHD.
  
  
  METHODS
  This was a review on medical and psychological literatures, particularly in the years 1995-2012.
  
  
  RESULTS
  As protective factor or risk factor, psychological factors play an important role in CHD.
  
  
  CONCLUSIONS
  Given the findings of this study, it seems necessary that we pay attention to psychological factors, as independent risk factors or protective factors for CHD.
