title: Long-term survival after coronary bypass surgery and percutaneous coronary intervention.
abstract: To assess whether there exists a long-term difference in survival after treatment with coronary bypass surgery or percutaneous coronary intervention in patients with coronary disease as judged by all-cause mortality.
  
  
  
  Retrospective study from the Feiring Heart Clinic database of survival in 22 880 patients-15 078 treated with percutaneous coronary intervention and 7802 with bypass surgery followed up to 16 years.
  
  
  
  Cox regression and propensity score analysis showed no difference in survival for one-vessel and two-vessel disease during the whole study period. In three-vessel disease, however, the analysis revealed a consistent and highly significant survival benefit in the first 8 years with an HR of 0.76 (95% CI 0.69 to 0.84, p<0.001) in favour of bypass surgery with similar survival rates in the two treatment strategies after that time period.
  
  
  
  Treatment strategy did not affect survival in one-vessel and two-vessel disease, but bypass surgery offered an improved survival in the first 8 years in patients with three-vessel disease. These results are consistent with most previous reports and the survival benefit should be taken into account when selecting a strategy for this patient group.
