Eitel Risk Score of Stiermaier et al for ST-Segment Elevation Myocardial Infarction (STEMI) Using Cardiac Magnetic Resonance Imaging (MRI)

Description

Stiermaier et al reported a risk score for a patient with ST-segment elevation myocardial infarction (STEMI) using cardiac magnetic resonance. The authors are from University Hospital Schleswig-Holstein and the German Center for Cardiovascular Research in Germany.


The score is named for the last author on the paper.

 

Patient selection: ST-segment elevation myocardial infarction (STEMI)

 

Evaluation used cardiac magnetic resonance imaging, using intravenous contrast to evaluate infarct size and microvascular obstruction.

 

Outcome: MACE (major adverse cardiac events)

 

Parameters:

(1) left ventricular ejection fraction (LVEF) in percent

(2) infarct size in percent

(3) microvascular obstruction in percent
