Abstract

Acute myocardial infarction (AMI) has a high incidence rate and is one of the leading causes of mortality among cardiovascular diseases. In some cases of inferior AMI, electrocardiograms (ECG) show ST-segment elevation in both inferior and anterior leads, which may be due to occlusion of a wrapped left anterior descending artery (LAD). Patients with wrapped LAD occlusion tend to have higher rates of complications and mortality. In this article, we describe three clinical cases of AMI confirmed by coronary angiography to have wrapped LAD occlusion. Post-coronary intervention echocardiograms revealed severe hypokinesia and akinesia in the apical region, along with heart failure due to reduced ejection fraction following the infarction. Although current ECG criteria for predicting wrapped LAD occlusion are not yet sufficiently reliable for diagnosis, they do raise awareness for early revascularization interventions to reduce the risk of complications and mortality in these patients.
