Acute Myocardial Infarction on Contrast-Enhanced Computed Tomography
Journal Title: Imaging Journal of Clinical and Medical Sciences - Year 2016, Vol 3, Issue 1
Abstract
A 79-year-old man presented to our emergency department with sudden back pain. Laboratory results showed CK 2836 U/L (normal range 30-160), CK-MB 393 U/L (<25), D-dimer 1.4 µg/mL (<1), BNP 37.9 pg/mL (<19.5), cTnl 0.133ng/mL (<0.028) and electrocardiogram showed ST elevation in V1~6. Acute myocardial infarction (AMI) was suspected. Because of the back pain, acute aortic dissection (AAD) and pulmonary thromboembolism (PE) needed to be ruled out and contrast-enhanced computed tomography (CECT) was performed. CECT images showed no findings of AAD or PE. Instead, the images revealed the decreased enhancement in the interventricular septum and apex of the left ventricle (Figure A,B, arterial phase, Figure C,D, delayed phase). With the diagnosis of ST elevated MI (STEMI), emergent invasive coronary angiography was carried out to reveal total occlusion of LAD, corresponding to the CT findings.
