Survival After Varying Revascularization Strategies in Patients With ST-Segment Elevation Myocardial Infarction and Multivessel Coronary Artery Disease (original) (raw)
2016, JACC: Cardiovascular Interventions
OBJECTIVES The authors conducted a systematic pairwise and network meta-analysis to assess optimal treatment strategies in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease (MV-CAD) undergoing primary percutaneous coronary intervention (PCI). BACKGROUND Patients with STEMI and MV-CAD have a worse prognosis than those with single-vessel CAD. The optimal revascularization strategy for these patients is uncertain. METHODS Studies of revascularization strategies for MV-CAD in STEMI patients undergoing primary PCI published between 2001 and 2015 were identified using an electronic search. Pairwise and network meta-analyses were performed for 3 PCI strategies in prospective and retrospective studies: 1) infarct-related artery (IRA)-only PCI; 2) single procedure MV-PCI; and 3) staged MV-PCI. Information on study design, inclusion and exclusion criteria, and clinical outcomes was extracted. The outcomes of interest were short-term and long-term mortality. RESULTS Thirty-two studies (13 prospective and 19 retrospective) with 54,148 patients (IRA-only PCI [n ¼ 42,112], single procedure MV-PCI [n ¼ 8,138], and staged MV-PCI [n ¼ 3,898]) were included in the analysis. Pairwise metaanalyses showed that staged MV-PCI was associated with lower short-term and long-term mortality compared with both IRA-only PCI and single stage MV-PCI, whereas IRA-only PCI was associated with lower mortality compared with single stage MV-PCI. Staged MV-PCI was also associated consistently with improved survival in network analyses. CONCLUSIONS The present systematic review and meta-analysis supports the hypothesis that in patients with MV-CAD presenting with STEMI undergoing primary PCI, a staged multivessel revascularization strategy may improve early and late survival.
