AMI Core Measures Inclusion Criteria for STEMI

Is there documentation of ST-segment elevation or left bundle branch block (LBBB) on the electrocardiogram (ECG) performed closest to hospital arrival?

Inclusion Guidelines for Abstraction:

ST-segment elevation

• Myocardial infarction (MI), with any mention of location or combinations of locations (e.g., anterior, apical, basal, inferior, lateral, posterior, or combination, IF DESCRIBED AS ACUTE/EVOLVING (e.g., “posterior AMI”)

• Q wave MI, IF DESCRIBED AS ACUTE/EVOLVING

• ST ↑

• ST, ST abnormality, or ST changes consistent with injury or acute/evolving MI

• ST-elevation (STE)

• ST-elevation myocardial infarction (STEMI)

• ST-segment noted as greater than or equal to 10mV

• ST-segment noted as greater than or equal to 1 mm

• Transmural MI, IF DESCRIBED AS ACUTE/EVOLVING

Left bundle branch block (LBBB)

• Intraventricular conduction delay of LBBB type

• Variable LBBB
