Appendix A. Continued 26 Short Title: PM-11: Time to Primary PCI Among Transferred Patients PM-11: Acute STEMI: Time From FMC (at or Before ED Arrival at STEMI Referral Facility) to Primary PCI at STEMI Receiving Facility Among Transferred Patients Measure Description: Percentage of patients, age 18 y, with acute STEMI, or its equivalent, whose median time from FMC (at or before ED arrival to the STEMI referral facility [eg, non PCI-capable facility]) to primary PCI at the STEMI receiving facility (PCI-capable facility) is 120 min. Numerator Patients with acute STEMI (or its equivalent*) defined by characteristic symptoms of myocardial ischemia with diagnostic ST elevation on ECG, who are transferred to a PCI-capable hospital and have received primary PCI 120 min from FMC *Patients with STEMI equivalent on ECG may have: hyperacute T-wave changes, true posterior MI, multilead ST depression with coexistent ST elevation in lead aVR, characteristic diagnostic criteria in the setting of LBBB.
