Table 2.
Prevalence of recognized and unrecognized myocardial infarction (MI) by CMR or ECG stratified by diabetes status. UMI by CMR were observed roughly twice as often as recognized MI. The prevalence of MI with the addition of ECG was significantly higher than the prevalence without ECG, but still significantly less than the increased prevalence with the addition of CMR (p<0.01 for both).
