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.

Influence of healthy candidate bias in assessing clinical effectiveness for implantable cardioverter-defibrillators: cohort study of older patients with heart failure.
This study assessed the potential contribution of unmeasured general health status to patient selection in assessments of implantable cardioverter-defibrillator (ICD) therapy. In a group of heart failure patients, those who received ICD therapy were younger and had lower ejection fraction and more cardiac admissions to hospital but fewer non-cardiac admissions. The lower risks of measured outcomes likely reflect unmeasured differences in comorbidity and frailty.
