Résumé
We sought to determine national trends and long term outcomes of post myocardial infarction (MI) heart failure. An MI can be complicated by heart failure; there are limited data describing the contemporary patterns and clinical implications of post-MI heart failure. We studied patients with an MI aged 65 years or older from 2000 to 2013 in a Medicare database. New-onset heart failure after an MI was defined as either heart failure during the index MI admission or a hospitalization for heart failure within 1 year of the index MI event. A trend analysis of the incidence of heart failure was performed, and differences were examined by Gray tests. The 5-year mortality rates were evaluated and differences among heart failure cohorts were ascertained by Gray tests. There were a total of 1,531,638 patients with an MI and 565,291 patients had heart failure (36.0%). The rate of heart failure during index admission was 32.3% and the frequency of heart failure hospitalization within 1 year was 10.4%. Patients with heart failure were older (81 years vs 77 years). The temporal trend from 2001 to 2012 suggested a decrease in the incidence of heart failure during index admission (2001: 34.7%, 2012: 31.2%, P Post-MI heart failure in older adults occurs in 1 in 3 patients within 1 year; heart failure portends significantly higher long-term mortality.

BACKGROUND
We sought to determine national trends and long term outcomes of post myocardial infarction (MI) heart failure. An MI can be complicated by heart failure; there are limited data describing the contemporary patterns and clinical implications of post-MI heart failure.
METHODS AND RESULTS
We studied patients with an MI aged 65 years or older from 2000 to 2013 in a Medicare database. New-onset heart failure after an MI was defined as either heart failure during the index MI admission or a hospitalization for heart failure within 1 year of the index MI event. A trend analysis of the incidence of heart failure was performed, and differences were examined by Gray tests. The 5-year mortality rates were evaluated and differences among heart failure cohorts were ascertained by Gray tests. There were a total of 1,531,638 patients with an MI and 565,291 patients had heart failure (36.0%). The rate of heart failure during index admission was 32.3% and the frequency of heart failure hospitalization within 1 year was 10.4%. Patients with heart failure were older (81 years vs 77 years). The temporal trend from 2001 to 2012 suggested a decrease in the incidence of heart failure during index admission (2001: 34.7%, 2012: 31.2%, P
CONCLUSIONS
Post-MI heart failure in older adults occurs in 1 in 3 patients within 1 year; heart failure portends significantly higher long-term mortality.
