Primary PCI is superior to thrombolysis for STEMI treatment, with lower mortality and reinfarction rates. Stents provide better outcomes than balloon angioplasty alone. Door-to-balloon times under 120 minutes are optimal. For facilities without PCI capabilities, rapid transfer for primary PCI within 2 hours is recommended over thrombolysis if possible. Facilitated PCI, using drugs to establish early reperfusion before angioplasty, combines benefits of early reperfusion and easier intervention. Pre-procedural TIMI flow grade is a determinant of PCI success and outcomes.
Six angiographic indicators of large thrombus burden by
Yip and colleagues,depending upon the angiographic morphology are
features indicated “high-burden thrombus formation”:
1. A cut-off pattern of occlusion
2. Accumulated thrombus proximal to the occlusion
3. A reference lumen diameter of the IRA of >4.0 mm
4. An incomplete obstruction with an angiographic thrombus with
the greatest linear dimension more than 3 times the reference
lumen diameter
5. The presence of floating thrombus proximal to the lesion
6. A persistent dye stasis distal to the occlusion

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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

27. After 12 hours??? BRAVE-2 Rationale: While thrombolysis has been shown to produce no benefit after 12 hours, no similar studies have looked at primary PCI in this group. Study: 365 patients randomized to in an invasive arm or a conservative arm. The invasive group underwent angiography and then PCI if necessary, while the conservative group was treated with conventional medical therapy. The primary end point was infarct size determined by SPECT at five to 10 days. Results: Infarct size (%LV) was significantly reduced in the invasive arm (8.0 vs 13%; p=0.002). No clinical differences. Kastrati ACC 2005

Editor's Notes
A review of several randomized trials evaluating the relative efficacy of primary PCI in STEMI revealed that further improvement in procedural outcomes, myocardial salvage, preservation of ventricular function, and survival may be obtained in patients undergoing primary PCI, by improving TIMI flow in the culprit infarct vessel before angioplasty is performed. These observations, along with the results of DANAMI-2, suggest a combined approach of early aggressive pharmacologic therapy, targeted to optimize coronary flow prior to angiography, followed by primary or facilitated PCI, in patients presenting with STEMI to tertiary care hospitals or community-based hospitals without invasive capabilities, may be particularly advantageous.
A grading system (left panel) for coronary perfusion was developed to carefully compare fibrinolytic agents in the TIMI 1 trial. As shown in the right panel, the TIMI flow grade showed a striking inverse correlation with mortality at 6 weeks.
