Association of Anemia With Outcomes Among ST-Segment-Elevation Myocardial Infarction Patients Receiving Primary Percutaneous Coronary Intervention.
Anemia may confer a poor prognosis among patients with the acute coronary syndrome. However, few data exist on the association of anemia with in-hospital outcomes, including bleeding, among ST-segment-elevation myocardial infarction patients receiving primary percutaneous coronary intervention. ⋯ In a contemporary ST-segment-elevation myocardial infarction cohort receiving primary percutaneous coronary intervention, nearly 1 in 5 patients were anemic. Anemia was associated with increased comorbidities and higher-risk features on presentation and was independently associated with subsequent major in-hospital bleeding but not all-cause mortality. These results suggest that anemic ST-segment-elevation myocardial infarction patients may safely receive timely primary percutaneous coronary intervention but with particular consideration for bleeding avoidance strategies.
