Excerpt

Red blood cell distribution width (RDW), a measurement of the variability in size of circulating erythrocytes, has emerged as a strong prognostic factor in patients with heart failure1,2 and coronary disease,3,4 although the value considered as a risk factor is not yet known. Its relationship with the necrosis area in patients with ST-segment elevation acute myocardial infarction (STEMI) has not been previously evaluated. The aim of this study was to determine whether the prognostic impact of RDW in cardiovascular event rate in patients with STEMI was associated with the extent of myocardial necrosis.
