Abstract

- Background: We have previously discovered an unexpected high prevalence of unrecognized myocardial infarction (UMI) scars by delayed-enhanced magnetic resonance imaging (DE-MRI) in the general elderly population. We now investigated if those UMIs were associated with coronary artery disease (CAD). Methods: Eighty-eight subjects from the PIVUS study (age 75-years) who had been investigated with DE-MRI (45 with UMI and 43 without DE-MRI-detected scars) underwent coronary computed tomography angiography (CTA) to assess Agatston calcium score and coronary artery stenosis. Of those, 65 also performed an exercise ECG test. Results: No differences were found between the subjects with UMI and the group without DE-MRI-detected scars regarding the number of coronary artery segments with significant stenosis, Agatston calcium score, or degree of ST-depression at the exercise test. Conclusion: DE-MRI-detected UMI scars do not have an increased prevalence of coronary artery stenosis or signs of myocardial ischemia at exercise test when compared to a control group. These findings indicate that UMI scars in general are not related to CAD.
