Anemia has been shown to be associated with a worse prognosis, especially higher mortality in various pathological conditions. However, few studies have specifically examined its impact in acute coronary syndrome (ACS) patients. The purpose of our study was to assess the association between different quartiles of hemoglobin on admission and short- and long-term prognosis in patients with ACS. ⋯ Low baseline hemoglobin is associated with more comorbidities and can accurately predict 1-year mortality after an acute coronary syndrome.
