title: Complete versus culprit-only revascularization in ST-elevation myocardial infarction and multivessel disease.
abstract: In 30-60 % of patients presenting with ST-segment elevation myocardial infarction (STEMI), significant stenoses are present in one or more non-infarct-related arteries (IRA). This correlates with an increased risk of major adverse cardiac events (MACE). Current guidelines, do not recommend revascularization of non-culprit lesions unless complicated by cardiogenic shock or persistent ischemia after primary percutaneous coronary intervention (PCI). Prior observational and small randomized controlled trials (RCTs) have demonstrated conflicting results regarding the optimal revascularization strategy in STEMI patients with multivessel disease. Recently, randomized studies (PRAMI, CvLPRIT, and DANAMI 3-PRIMULTI) provide encouraging data that suggest potential benefit with complete revascularization in STEMI patients with obstructive non-culprit lesions. Differently, in the PRAGUE-13 trial there were no differences in MACE between complete revascularization and culprit-only PCI. Several meta-analyses were recently published including randomized and non-randomized clinical trials, showing different results depending on the included trials. In conclusion, the current available evidence from the randomized clinical trials, with a total sample size of only 2000 patients, is not robust enough to firmly recommend complete revascularization in STEMI patients. This uncertainty lends support to the continuation of the COMPLETE trial. This ongoing trial is anticipated to enroll 3900 patients with STEMI from across the world, and will be powered for the hard outcomes of death and myocardial infarction. Until the results of the COMPLETE trial are reported, physicians need to individualize care regarding the opportunity and the timing of the non-IRA PCI.
