title: Psychosocial Working Environment and Risk of Adverse Cardiac Events in Patients Treated for Coronary Heart Disease.
abstract: BACKGROUND
  During the last decades a possible association between psychosocial working environment and increased risk of coronary heart disease (CHD) has been debated and moderate evidence supports that high psychological demands, lack of social support and iso-strain (the combination of high job strain and lack of social support) is associated with primary CHD. Whether psychosocial working environment plays a role as risk factor for new cardiac events and readmissions in patients with existing cardiovascular disease is less studied.
  
  
  METHODS
  A cohort of patients <67 years treated with percutaneous coronary intervention (PCI) was established in 2006. Three months after PCI patients answered a questionnaire about their psychosocial working environment. Patients were followed in the Danish National Patient Registry and the Danish Civil Registration System for 3+ years to identify adverse cardiac events and death. We analysed the association between psychosocial working environment and adverse cardiac events by Cox Regression.
  
  
  RESULTS
  A number of 528 patients had returned to work 12 weeks after PCI, while 97 were still sick-listed. We identified 12 deaths and 211 other events during follow-up. We found no statistically significant associations between psychosocial working environment and risk of adverse cardiac events and readmissions or mortality.
  
  
  CONCLUSIONS
  The psychosocial working environment was not associated with adverse cardiac events.
