The early use of primary angioplasty in patients with ST-segment myocardial infarction (STEMI) results in a significant reduction in mortality and morbidity. The earlier primary coronary intervention is provided, the more effective it is (Brodie, 1998 and DeLuca, 2004). National guidelines recommend the prompt initiation of PCI in patients presenting with ST-elevation myocardial infarction (O'Gara, 2013; and Levine 2011).
Clinical Recommendation Statement
National guidelines recommend the prompt initiation of PCI in patients presenting with ST-elevation myocardial infarction.

To identify the ECG closest to hospital arrival, the denominator will identify the most recent ECG performed that starts less than 1 hour prior to the emergency department (ED) or inpatient encounter  OR the first ECG performed starts after the ED or inpatient encounter started.

PCI procedures analyzed in this measure must be primary procedures. Primary includes emergent or urgent PCI procedures and not those described by the physician/APN/PA anywhere in the record as elective, not emergent, not immediate, not primary, not urgent, or secondary.

From a clinical standpoint, Primary PCI is loosely defined as percutaneous coronary intervention performed in the acute setting in patients with ST segment elevation MI which is intended to restore perfusion in the infarct-related artery. There is currently no way to explicitly express this in QDM, however, using 'FIRST' will likely capture the intent the majority of cases.
Transmission Format
Initial Population
Patients age 18 and older at the time of hospital admission with a principal diagnosis of Acute Myocardial Infarction (AMI) with hospital stays <= 120 days during the measurement year
Initial population with an ECG (result: Acute or Evolving MI) and a primary PCI procedure closest to the inpatient admission that does not start after fibrinolytic therapy
Denominator Exclusions
Patients who transferred from another hospital's inpatient, outpatient, or emergency department and ambulatory surgery center facilities are excluded
AMI patients whose time from hospital arrival to primary PCI is 90 minutes or less
Numerator Exclusions
Not applicable
Denominator Exceptions
Patients who did not receive PCI within 90 minutes and has a documented reason. Documented reasons include:
"Diagnosis: Cardiopulmonary arrest"
"Procedure, Performed: Endotracheal Intubation"
"Procedure, Performed: Aortic balloon pump insertion"
"Procedure, Performed: Ventricular Assist Device placement"
Supplemental Data Elements
For every patient evaluated by this measure also identify payer, race, ethnicity, and sex
