Ndrepepa G, et al. - Whether the established markers of reperfusion in ST-segment elevation myocardial infarction (STEMI), ie, Thrombolysis in Myocardial Infarction (TIMI) flow, myocardial perfusion grade (MPG) and infarct size, provide long-term prognostic information was investigated. These markers were assessed by scintigraphy at 7-14 days post-reperfusion in 1406 patients with STEMI who underwent primary percutaneous coronary intervention (PCI). The primary outcome was 8-year mortality. Researchers noted that although long-term mortality after primary PCI in STEMI patients was independently predicted by these markers, they offered limited incremental prognostic value to evaluation of baseline cardiovascular risk factors and clinical data.
