A risk score based on simple angiographic characteristics to aid in choosing the optimal revascularization strategy for patients with multivessel disease presenting with ST-elevation myocardial infarction

Schamroth Pravda N, Witberg G, Zusman O, et al. - To recognize patients with ST-elevation myocardial infarction with multivessel disease (MV-STEMI) for whom a multivessel percutaneous coronary intervention (MV-PCI) might be beneficial than a PCI for only the infarct-related artery (IRA-PCI), researchers sought to construct a simple angiographic risk score in this retrospective analysis utilizing data from a single-center STEMI registry. A score was devised relied on three features of non-culprit lesions earlier documented to predict overall death (proximal left anterior descending artery involvement, maximal % stenosis, and number of involved vessels). The high-risk vs the low-risk group had higher risk of MACE (major adverse cardiac event). Relative to MV-PCI, IRA-PCI was shown to be related to less MACE in the low-risk group, and more MACE in the high-risk group. Overall, experts concluded that patients carrying a high risk of future adverse events could be identified using a simple risk score based on three angiographic characteristics, in a population of MV-STEMI patients that receive primary PCI. The selection of the optimal revascularization strategy might be facilitated using this score.
