Several studies have suggested that race might play a role in outcome of patients following acute coronary syndrome (ACS) admission.
To examine the association between patients’ race and long-term outcome after discharge following ACS admission from our hospital ACAP-PAIN registry.
The study population consisted of 5526 patients who were hospitalized with a diagnosis of ACS during the years of 2006–2010. According to our ACAP-PAIN registry all patients presented with ACS are prospectively followed in a hospital wide registry. Long-term outcomes (a composite of death, myocardial infarction (AMI), and ACS readmission) and related risk factors were assessed. Follow-up period was 4 years.
African Americans and Hispanics had higher composite endpoint (43 and 35%. respectively) compared to whites (31%; p < 0.001); (See Graph). African Americans (AA), (6%) and Hispanics (H), (5%) both had an increased risk of death compared to whites (4%). Readmission rates were highest among African Americans 31%, followed by Hispanics 26%, whites 20%, and Asians 17%, p <0.001. African Americans and Hispanics had higher prevalence of hypertension, diabetes, and heart failure.
AA and H patients presenting with ACS have significantly worse long-term outcome compared to patients of other races. This may be due in part to a higher incidence of significant co-morbidities in this patient population. More studies are needed to elucidate the mechanism of risk in these patients.
