New study on heart attack death rates

This came this afternoon from NIH. "Ninety days after acute myocardial infarction (AMI) — or heart attack — death rates for African Americans and white patients were found to be significantly higher in hospitals that disproportionately serve African-American patients than in hospitals that serve mainly white patients, according to a major new study led by researchers at Dartmouth Medical School. The researchers suggest that quality of care, more than racial differences per se, determines AMI outcomes." Unlike some studies, this had a huge sample -- more than 1 million people in Medicare over several years. Could be great way into racial/ethnic differences in health care quality. For those, like me, who believe you need to read the actual study, you can find it here, in Circulation.
