Abstract
Primary PCI is the preferred reperfusion strategy used in patients with acute STEMI to prevent progression of myocardial necrosis. Besides the advantages of this strategy, there are situations in which myocardial reperfusion is not restored to its optimal level. Angiographic no-reflow phenomenon, a reduced coronary antegrade flow (TIMI flow grade ≤2) without mechanical obstruction after recanalization, predicts poor LV functional recovery and survival in the early phase of STEMI. The no-reflow phenomenon is critical and, if not reversed, causes a high rate of morbidity and mortality. It was demonstrated that the no-reflow phenomenon after primary PCI is a strong predictor of death extending to up to 5 years after the acute event in patients with STEMI. Although the predisposing factors of the no-reflow phenomenon were investigated, there is little data about clinical and procedural predictors of this phenomenon. The aim of this study was to evaluate the significance of some specific haematological markers (neutrophil count, red cell distribution width, mean platelet volume, neutrophil lymphocyte ratio and platelet lymphocyte ratio) as predictive factors of no-reflow phenomenon following primary PCI.
