Despite the recent developments that have been made in the field of percutaneous left main (LM) intervention, the
treatment of distal LM bifurcation remains challenging. The provisional one-stent approach for LM bifurcation has
shown more favorable outcomes than the two-stent technique, making the former the preferred strategy in most
types of LM bifurcation stenosis. However, elective two-stent techniques, none of which has been proven superior
to the others, are still used in patients with severely diseased large side branches to avoid acute hemodynamic
compromise. Selecting the proper bifurcation treatment strategy using meticulous intravascular ultrasound evaluation
for side branch ostium is crucial for reducing the risk of side branch occlusion and for improving patient outcomes. In
addition, unnecessary complex intervention can be avoided by measuring fractional flow reserve in angiographically
isolated side branches. Most importantly, good long-term clinical outcomes are more related to the successful
procedure itself than to the type of stenting technique, emphasizing the greater importance of optimizing
the chosen technique than the choice of metho

This highly energetic lecture presents the pathophysiology of S-T elevation myocardial infarction in an easy to understand style to help you best identify, triage and treat patients presenting with acute coronary syndromes. Using the latest research behind the AHA Guidelines changes, AHA National Faculty Rom Duckworth will help you better coordinate with you partners along the continuum of cardiac care. Emphasis is placed on risk factors, recognizing truly sick patients and coordinating care with hospital personnel.
Learning Objectives: Students will learn:
-The pathophysiology of S-T elevation myocardial infarction.
-The difference between STEMI, NSTEMI and unstable angina.
-Differing treatment methods and priorities for different cardiac syndromes.
-The function and importance of 12 lead ECG and prehospital diagnostic testing.
-The roles and responsibilities of EMS providers as the key element in “door-to-balloon” and “door-to-needle” time for STEMI patients.
