Pseudomyocardial Infarction: An Atypical Presentation of Chest Wall Necrotizing Fasciitis

Abstract

A 75-year-old woman was admitted because of acute chest pain for one day. The electrocardiogram (ECG) showed progressive decreasing R wave amplitudes with new QS waves at precordial leads in three hours (Figure 1 A, B). Serial high-sensitivity cardiac troponin testing at baseline and three hours after admission were within normal range (8.8 pg/mL and 11.1 pg/mL respectively. Upper reference limit: 17.5 pg/mL). The white-cell count was 6800 /µL (reference range: 4800 to 10,800). The contrast-enhanced computer tomography of chest showed no aortic dissection or pulmonary embolism (Figure 3A).
