Race, Bleeding, and Outcomes in STEMI Patients Treated with Fibrinolytic Therapy.

Journal Article

BACKGROUND: studies have shown higher bleeding and mortality rates among African Americans who receive fibrinolytic therapy for ST-segment elevation myocardial infarction (STEMI) compared with whites; however, the relationship of bleeding risk to mortality has not been evaluated. METHODS: we studied data from 32,260 STEMI patients receiving fibrinolysis enrolled in the US in 5 clinical trials. Bleeding was defined according to criteria from the Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries study. Main outcome measure was adjusted 1-year mortality. RESULTS: despite younger age (median: 57 years vs 61 years) and fewer comorbidities, moderate or severe bleeding occurred more frequently among African-Americans than whites (16.3% vs 14.1%; P=.0147, adjusted OR 1.36; 95% confidence interval [CI], 1.14-1.62; P=.0006) as did 1-year mortality (11.5% vs 9.4%). African-American race and moderate or severe bleeding were independently related to 1-year mortality (χ(2) 9.02, P=.0003 and 148.58, P<.0001, respectively). Mortality was highest among African Americans with bleeding (hazard ratio [HR] 2.83; 95% CI, 2.08-3.86) followed by whites with bleeding (HR 1.99; 95% CI, 1.78-2.22) and African Americans without bleeding (HR 1.33; 95% CI, 1.02-1.73) (referent whites without bleeding). CONCLUSIONS: in STEMI patients receiving fibrinolysis, moderate or severe bleeding and mortality were significantly higher in African Americans compared with whites. Bleeding was associated with similarly increased mortality risk in both groups.
