An 82-year-old female after a stress event, with no past medical history of cardiovascular diseases, was referred for emergency coronary angiography. She was suffering from chest pain, with a blood pressure of 124/67 mmHg and a heart rate of 76 b.p.m. Prominent ST-segment elevation in V1–V5 and increased troponin I level (14.82 ng/mL) suggested anteroseptal acute myocardial infarction. Urgent angiography documented no coronary artery disease (Panel A). Bedside echocardiography revealed abnormal left ventricular (LV) contraction with an ‘apical ballooning’ pattern; LV ejection fraction was 55% (Panel B). The bull's-eye parametric image of the peak longitudinal systolic strain indicated dyskinesis of the apical segments, not pathognomonic for acute myocardial infarction (Panel B).
