Figure 3. Subtle ST segment elevation in anteroapical wall; electrocardiogram displaying a subtle STE of approximately 1 mm in V1-V4, which does not fulfil the criteria set by the Universal Definition of Myocardial Infarction. The use of the 4-variable calculator indicated Occlusion Myocardial Infarction (OMI). Subsequent coronary angiography confirmed occlusion of the left anterior descending artery.
