Abstract

The present investigation, performed in 1,122 consecutive STEMI patients treated with primary coronary intervention, was aimed at evaluating: (1) the prevalence of prior anemia and its prognostic significance in the short term; and (2) the prevalence of new anemia and its impact in the short term. The prevalence of prior anemia was 27. 4%. Patients with a prior anemia were older and exhibited a higher incidence of chronic diseases and comorbidities. They showed a higher intra-hospital mortality rate (p <0. 001), a higher incidence of PCI failure (p <0. 001) and major bleedings (p <0. 001). Prior anemia was an independent predictor for intra-hospital mortality (OR 2. 12; 95% CI 1. 21-3. 70, p = 0. 009). Patients with a new anemia account for 46. 8% of our series, and showed a higher early mortality rate and incidence of major bleedings in respect to those who maintained normal Hb values (p <0. 05 and
