The impact of heart failure on clinical and economic outcomes among older adults with acute myocardial infarction

HF after an AMI is a major contributor to cardiovascular mortality.


Study Design

The study included 468,654 patients admitted for AMI between January 1, 2000 and December 31, 2016. Investigators identified AMI admission using the primary diagnosis and incidence of HF using any secondary diagnosis. Outcomes of the study included overall mortality as well as length of hospital stay. 

Results and Conclusions

HF was common among AMI patients, with 42,946 (9%) study participants diagnosed with HF during their AMI admission. The overall mortality rate for patients with HF was 12%, the median hospital length of stay was 5 days, and only a quarter of patients were discharged home. 

A larger proportion of patients were discharged to rehabilitation or hospice if they had AMI and HF compared to AMI alone. The average adjusted cost of an AMI hospitalization increased by $1075 for patients with HF in comparison to AMI patients without HF.
