Abstract
Methods Eighty consecutive patients with first presentation of TnI+ chest pain underwent ceMRI at a mean (SD) of 64 (23) hours from chest pain on a Siemens Sonata 1.5 T system using a phased array chest coil during breath-holds. Cinematographic images were acquired using a steady state free precession sequence. CeMRI was performed > 15 minutes after peripheral injection of 0.2 mmol/kg gadolinium-DTPA using a segmented gradient-echo inversionrecovery sequence for DE. Scans were assessed by 2 experienced observers and DE was planimetered manually. CA was performed at the discretion of the Cardiologist in charge of patients care, minimal disease is defined as < 25% maximal stenosis. Patients were divided by pattern of DE into AMI (subendocardial) and cardiomyopathy (subendocardial sparing).
Highlights
International guidelines recommend early coronary angiography (CA) and revascularization in all patients diagnosed with acute myocardial infarction (AMI)
Patients were divided by pattern of delayed hyperenhancement (DE) into AMI and cardiomyopathy
One patient was negative for DE and had a TnI of 4.4 ng/ ml; a final diagnosis of Takotsubo cardiomyopathy was made by characteristic cinematographic images
