- for the Myocardial Infarction Data Acquisition System (MIDAS) Study Group
Background: The case fatality of myocardial infarction (MI) has been decreasing for several decades. However, scant data are available on whether the improvement in in-hospital and at one year mortality is magnified, diminished, or remains stable over the recent 15 year period.
Methods: Using the Myocardial Infarction Data Acquisition System (MIDAS), a statewide database of all cardiovascular hospital admissions in New Jersey, we identified 201,571 patients with a primary diagnosis of MI. We examined time trends in MI case fatality from the year 2000 to the year 2014.
Results: In the oldest age group (70-84), in-hospital case fatality decreased from 12.0 % to 7.0 %, a decline of 41.7%, from 2000 to 2014. The case fatality at one year decreased from 21.0 % to 18.9 %, a decline of 10.0%. Thus, more than 55% of the reduction in case fatality at discharge was lost at one year (5.1 % vs. 2.2%). This effect was also observed in the other two age groups (40 to 54 and 55 to 69) but was not as pronounced.
Conclusions: A decline in in-hospital and one year MI case mortality was observed in all age groups but was more pronounced in absolute terms in the oldest age group. More than 50% of the reduction in case fatality in the age group 70-84 at discharge was lost at one year. This may be due to competing risk with non-cardiovascular causes of death.
