Single vs multivessel treatment during primary angioplasty: results of the multicentre randomised HEpacoat™ for cuLPrit or multivessel stenting for Acute Myocardial Infarction (HELP AMI) Study

DESIGN: Prospective randomized, multicentre study. RATIONALE: Recanalisation of the culprit lesion is the main goal of primary angioplasty for acute myocardial infarction. With the exception of cardiogenic shock, staged procedures are performed in the presence of multivessel disease. The study hypothesis is that with modern non-thrombogenic stents (heparin coated) complete revascularization with multivessel treatment can be safely achieved during the primary angioplasty procedure with a lower need of subsequent revascularization procedures and at a lower cost. ENDPOINTS: PRIMARY: 12-month incidence of repeat revascularization (any revascularization, infarct related artery as well as non-infarct-related artery). SECONDARY: (1) in hospital repeat revascularization, reinfarction and death; (2) total hospital cost (including a 12 months follow-up period). METHODS: 69 patients with ST elevation Acute Myocardial Infarction (AMI), <12 hours after symptoms onset, undergoing primary angioplasty, with documented...
