Prognostic Impact of Age and Hemoglobin in Acute ST-Segment Elevation Myocardial Infarction Treated With Reperfusion Therapy

Abstract Advanced age and low hemoglobin levels have been associated with a poor prognosis in ST segment elevation myocardial infarction (STEMI). We studied 1111 STEMI patients that received reperfusion treatment (1032 [92.9%] primary angioplasty and 79 [7.1%] fibrinolysis without rescue percutaneous coronary intervention). Mean age was 64.1±14.0 years, 23.2% were women. Patients in the last age quartile (>76 years) were more frequently female, presented more risk factors (except smoking), received thrombolysis less frequently, had less complete revascularization, and presented more complications and higher mortality. Hemoglobin level at admission was associated with age and ranged from 14.8±1.5 g/dL in the first quartile to 13.2±1.8 g/dL in the last, p
