EVIDENCE-BASEDPERFORMANCE MEASURES

- 1. ST-segment elevation 2.5mm in men < 40 years, in leads V2–
V3
- 2. 2mm in men > 40 years in leads V2–V3
- 3. 1.5mm in women in leads V2–V3
- 4. 1mm in the other leads [in the absence of left ventricular (LV)
hypertrophy or left bundle branch block LBBB)].

SLIDE 66 FIBRINOLYTICS
tenecteplase tissue plasminogen activator (TNK-tPA) is equivalent to accelerated tPA in reducing 30 day mortality, but is safer in preventing non-cerebral bleeds and blood transfusion, and is easier to use in the pre-hospital setting
SLIDE 67
- 1. Tenecteplase tissue plasminogen activator (TNK-
tPA) is equivalent to accelerated tPA in reducing 30 day mortality,
- 2. TNK is safer compared to TPA in preventing non-
cerebral bleeds and blood transfusion, and is easier to use in the pre-hospital setting

SLIDE 81 IN SUMMARY
- 1. Have an institutional approach to chest pain
- 2. Exclude other possible fatal causes
- ACS and the differential diagnosis as discussed
- 3. Electrocardiogram within 10m minutes of arrival
- 4. Biomarkers and repeat at 3 hours to confirm or exclude a
rise/fall.
- 5. If unsure, then pick up the phone and call
- 6. If suspecting an ACS, commence AspIrin loading and
activate the ACS network
- 7. STEMI: time is muscle. If no PCI Lysis
