National trends in recurrent AMI hospitalizations 1 year after acute myocardial infarction in Medicare beneficiaries: 1999-2010.
The investigators evaluated changes in the incidence of 1-year recurrent acute myocardial infarction (AMI) hospitalization and mortality. In a national sample of Medicare beneficiaries hospitalized for AMI from 1999 to 2010, they found that hospitalization for recurrent AMI decreased, as did subsequent mortality, albeit to a lesser extent. The risk of recurrent AMI hospitalization declined less in black patients than in whites, increasing observed racial disparities by the end of the study period.

Claims-based algorithms for identifying Medicare beneficiaries at high estimated risk for coronary heart disease events: a cross-sectional study.
The researchers sought to develop claims-based algorithms to identify individuals at high risk for coronary artery disease (CHD) and to identify low-density lipoprotein (LDL) cholesterol among statin users at high risk for CHD events. They found that despite low sensitivity, the high predictive value of their algorithm for high risk for CHD events supports the use of claims to identify Medicare beneficiaries at high risk for CHD events.
