First-year acute coronary event rates in patients with acute myocardial infarction evaluated 5-7 days post-MI for ST depression in an ambulatory monitored ECG.
BACKGROUND
To present rates for fatal and non-fatal acute coronary events (ACE) in patients monitored 5-7 days after acute myocardial infarction, for abnormal ST depression in a continuous ambulatory ECG, with follow-up to the end of the first year after hospital admission. Comparative first-year mortality rates are also derived.


RESULTS
The comparative mortality in the ischemic group is at an excess death rate of 92 per 1,000 per year as opposed to the nonischemic group where it was 15 per 1,000 per year. Nonfatal ACE rates were 346 and 154 per 1,000 per year, respectively, in the two groups.


CONCLUSIONS
The risk of death is extremely high in the first few minutes and the first hour after the onset of an acute MI, and the risk diminishes steadily over the ensuing days weeks and months.
