title: Acute Coronary Syndrome Treatment Costs from the Perspective of the Supplementary Health System.
abstract: BACKGROUND
  Acute coronary syndrome (ACS) is defined as a "group of clinical symptoms compatible with acute myocardial ischemia", representing the leading cause of death worldwide, with a high clinical and financial impact. In this sense, the development of economic studies assessing the costs related to the treatment of ACS should be considered.
  
  
  OBJECTIVE
  To evaluate costs and length of hospital stay between groups of patients treated for ACS undergoing angioplasty with or without stent implantation (stent+ / stent-), coronary artery bypass surgery (CABG) and treated only clinically (Clinical) from the perspective of the Brazilian Supplementary Health System (SHS).
  
  
  METHODS
  A retrospective analysis of medical claims of beneficiaries of health plans was performed considering hospitalization costs and length of hospital stay for management of patients undergoing different types of treatment for ACS, between Jan/2010 and Jun/2012.
  
  
  RESULTS
  The average costs per patient were R$ 18,261.77, R$ 30,611.07, R$ 37,454.94 and R$ 40,883.37 in the following groups: Clinical, stent-, stent+ and CABG, respectively. The average costs per day of hospitalization were R$ 1,987.03, R$ 4,024.72, R$ 6,033.40 and R$ 2,663.82, respectively. The average results for length of stay were 9.19 days, 7.61 days, 6.19 days and 15.20 days in these same groups. The differences were significant between all groups except Clinical and stent- and between stent + and CABG groups for cost analysis.
  
  
  CONCLUSIONS
  Hospitalization costs of SCA are high in the Brazilian SHS, being significantly higher when interventional procedures are required.
