Novel Imaging Biomarkers for Mechanical Complications in Acute Myocardial Infarction

WSI Ratio as a Biomarker for Mechanical Complication of Hemorrhagic MI

Hemorrhagic Myocardial infarctions are at high risk for mechanical complications including cardiac rupture. Prediction of vulnerable myocardial segments is an important step for the stratification of hemorrhagic MI patients. Wall motion index ratio is an important parameter to determine regions of high vulnerability within the 17-segment LV model of hemorrhagic MI.
