title: HRQoL after coronary artery bypass grafting and percutaneous coronary intervention for stable angina.
abstract: OBJECTIVE
  To assess the health related quality of life (HRQoL) and the change in the NYHA class after coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in the management of stable coronary artery disease (CAD). The study was non-randomized. CABG group consisted of 240 patients and 229 patients were treated with PCI. HRQoL was measured prospectively by the 15D instrument.
  
  
  RESULTS
  Three-year survival was 95.0 and 95.6% (NS). The HRQoL improved statistically in both groups until 6 months after treatment but deteriorated towards the end of the follow-up of 36 months. Clinically evident improvement of the HRQoL and decrease of the NYHA class took place more frequently among CABG patients.
  
  
  CONCLUSIONS
  Despite initially more serious preoperative state and more demanding procedure CABG patients achieve equal level of HRQoL when compared with PCI patients. CABG patients may also obtain better relief from symptoms in mid-term follow-up. HRQoL cannot be the only factor to determine outcome after invasive treatment of CAD but it has to be placed in the context of the overall situation.
