title: Single or multivessel percutaneous coronary intervention in ST-elevation myocardial infarction patients.
abstract: OBJECTIVE
  To evaluate clinical results of percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) in patients with multivessel disease (MVD), in relation to single or multivessel (MV)-PCI and to patients with single vessel disease (SVD).
  
  
  METHODS
  Patients treated with PCI in the setting of <24 hr STEMI in the years 2004-2007 were considered.
  
  
  RESULTS
  Seven hundred forty-five primary PCI, 346 (46%) in patients with SVD and 399 (54%) in patients with MVD were performed. Among MVD patients, 156 (39%) had infarct related artery (IRA)-only treatment and 243 had MV-PCI: 147 (37%) in a single session, 48 (12%) within 24 hr, and 48 (12%) predischarge. Revascularization was complete in 46% of MVD patients. At a median follow-up of 597 days, mortality was 6.3% in SVD and 12% in MVD (P = 0.007), new revascularization 2.9% and 9%, respectively (P < 0.001). Thirty-day mortality was 2.4% in SVD and 6.7% in MVD (P = 0.006). After exclusion of patients with cardiogenic shock or pulmonary oedema, more frequent in the MV-PCI in single session group (P = 0.006), 30-day mortality was SVD 1.3%, IRA-only 6.3%, MV-PCI 2.8% (P = 0.023), without differences if in a single (3.3%) or in staged session (2.2%). By multivariate analysis, female sex, anterior STEMI, cardiogenic shock, MVD, and procedural failure were independent predictors of 30-day mortality.
  
  
  CONCLUSIONS
  STEMI patients with MVD have a worse prognosis than those with SVD. MV-PCI in patients without hemodynamic compromise yields good short-term results, even if performed very early, with a 30-day mortality in between that of SVD patients and that of MVD patients with IRA-only treatment.
