title: Primary percutaneous coronary intervention for ST-segment elevation acute myocardial infarction in nonagenarian patients: results from a Spanish multicentre registry.
abstract: OBJECTIVE
  Data on primary percutaneous coronary intervention for ST-segment elevation in nonagenarian patients are very limited. Our aim was to evaluate the results of primary percutaneous coronary intervention in patients ≥ 90 years old with ST-segment elevation acute myocardial infarction.
  
  
  RESULTS
  We conducted a multicentre registry focused on nonagenarians treated with percutaneous coronary interventions, gathering data from five tertiary centres in Spain. We included 38 patients with ST-segment elevation acute myocardial infarction who presented within 12 hours after symptoms onset and who were treated with primary percutaneous intervention. Mean age was 91.5 (90-98). Angiographic success was achieved in 90%, and TIMI 3 flow in 76% of cases. In-hospital mortality was 34.2%, concentrated in patients with major bleeding (100% vs. 31.4%), final TIMI flow grade <3 (71.4% vs. 22.7%), and Killip class > I at admission (53.3% vs. 21.7%).
  
  
  CONCLUSIONS
  Primary percutaneous coronary intervention in nonagenarians with ST-segment elevation acute myocardial infarction is associated with high rate of successful recanalisation of the infarct-related artery. Mortality is concentrated in patients with severe bleeding during hospitalisation, heart failure at admission, and final TIMI flow <3.
