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

Multivessel treatment during primary PTCA was safe in this controlled trial. However, when only the culprit lesion was initially treated, the need for subsequent clinically driven revascularization remained low and no clinical or economical advantages were obtainable with a more aggressive initial approach. In clinical practice, a staged approach to multivessel treatment during primary angioplasty avoids to treat unnecessarily non clinically relevant lesions.
