Acute Ischemia Index of Hassell et al and the Percentage of the Myocardial Area at Risk Following an Inferior Myocardial Infarction

Description

Hassell et al used the acute ischemia index to determine the percentage of the myocardial area at risk (MaR) following an inferior ST-elevated myocardial infarction. The authors are from AMC Medical Center of Amsterdam, Maastricht University, Duke University, Catharina Hospital (Eindhoven), and the University of Washington.


 

Patient selection: inferior ST-segment elevated acute myocardial infarction

 

Parameters:

(1) Aldrich score for an inferior AMI (see 07.03.05) at the time of admission

(2) Selvester score (see 07.03.02, maximum score 32) at the time of admission

 

acute ischemia index =

= (Aldrich score) / ((Aldrich score) + (Selvester score)) * 100%

 

Interpretation:

• The acute ischemia index indicates the percentage of the myocardial area at risk that is ischemic on admission.
