Abstract

BACKGROUND:

Asian-Americans represent an important United States minority population, yet there are limited data regarding the clinical care and outcomes of Asian-Americans following acute myocardial infarction (AMI). Using data from the American Heart Association Get With The Guidelines-Coronary Artery Disease (GWTG-CAD) program, we compared use of and trends in evidence-based care AMI processes and outcome in Asian-American versus white patients.

METHODS AND RESULTS:

We analyzed 107,403 AMI patients (4412 Asian-Americans, 4.1%) from 382 United States centers participating in the Get With The Guidelines-Coronary Artery Disease program between 2003 and 2008. Use of 6 AMI performance measures, composite "defect-free" care (proportion receiving all eligible performance measures), door-to-balloon time, and in-hospital mortality were examined. Trends in care over this time period were explored. Compared with whites, Asian-American AMI patients were significantly older, more likely to be covered by Medicaid and recruited in the west region, and had a higher prevalence of diabetes, hypertension, heart failure, and smoking. In-hospital unadjusted mortality was higher among Asian-American patients. Overall, Asian-Americans were comparable with whites regarding the baseline quality of care, except that Asian-Americans were less likely to get smoking cessation counseling (65.6% versus 81.5%). Asian-American AMI patients experienced improvement in the 6 individual measures (P≤0.048), defect-free care (P<0.001), and door-to-balloon time (P<0.001). The improvement rates were similar for both Asian-Americans and whites. Compared with whites, the adjusted in-hospital mortality rate was higher for Asian-Americans (adjusted relative risk: 1.16; 95% confidence interval: 1.00-1.35; P=0.04).

CONCLUSIONS:

Evidence-based care for AMI processes improved significantly over the period of 2003 to 2008 for Asian-American and white patients in the Get With The Guidelines-Coronary Artery Disease program. Differences in care between Asian-Americans and whites, when present, were reduced over time.
