An important and useful article has been published that deserves our attention.
Rokos IC, French WJ, Mattu A, Nichol G, Farkouh ME, Reiffel J, Stone GW (December 2010). “Appropriate Cardiac Cath Lab activation: Optimizing electrocardiogram interpretation and clinical decision-making for acute ST-elevation myocardial infarction“. Am Heart J 160 (6): 995–1003.e8
Here are some comments from the lead author Ivan Rokos, MD that I received in an email.
You may recall that I published an article with Dr. Rokos entitled “The emergency medical systems-to-balloon (E2B) challenge: building on the foundations of the D2B Alliance.”
Here’s what Dr. Rokos had to say in his email:
“A big issue for STEMI receiving centers is false positives or inappropriate Cath Lab activations and my goal is to prevent this from becoming the Achilles heel of STEMI systems. Thus we propose a benchmark of less than 5% rate of inappropriate Cath Lab activations in a STEMI system.
Other key points from our recent AHJ paper:
- Perhaps of primary interest is our group’s efforts to provide a terminology outline that is comprehensive and precise….”classic” STEMI, STEMI-equivalents, STE-mimics, and semi-STEMI
- Table 1 compares 2004 ACC/AHA guideline recommendations with our group’s proposed updates (note: topic not updated in 2007 or 2009 GL).
- We have also raised concern regarding “new LBBB” as a Class I-A recommendation….and this manuscript provides the supporting rationale in detail.
- Isolated Posterior MI is also reviewed….and highlights huge opportunities from improved diagnostic sensitivity.
- We also describe some esoteric but real conditions….De Winter ST/T waves and STE in lead AVR for acute Left Main occlusion
- We attempted to provide a strong supporting rationale to bridge STEMI and out-of-hospital cardiac arrest (OHCA) systems and regional networks.
- Beyond the ECG, clinical decision making is emphasized for “appropriateness” before Cath lab activation.
- Lastly, SPEED has been a key focus of STEMI systems and much has been accomplished regarding D2B and E2B times. However, I believe the next big challenge is EFFICIENCY and optimizing resource utilization, and that is a primary focus of our AHJ manuscript.”
