Inclusive of unstable angina and NSTEMI

These are the same clinical syndrome, with the only distinction being the objective identification of myonecrosis with NSTEMI

Neither UA or NSTEMI are necessarily associated with ischemic ECG changes Result from partial or intermittent obstruction

of epicardial vessels, or complete obstruction of distal branches

In contradistinction, STEMI is complete obstruction of larger vessel, which is associated with ECG changes

Non-ST-Segment-Elevation ACSNon-ST-Segment-Elevation ACS

UA/NSTEMI typically result from fissure or frank rupture of an atherosclerotic plaque Stimulates local activation of:

• platelets• coagulation cascade• complement

Platelet aggregate forms over site of plaque injury . . . but remains unstable and subject to shear forces from passing blood flow

No obstruction in situ, but downstream embolization can occur• perhaps resulting in ST↓ or troponin leak

Pharmacologic therapy in NSTE ACS is therefore directed at this triad of abnormal activity: Platelet activation—anti-activation and anti-

aggregation• ASA and clopidogrel• GPIs

Coagulation activation—anticoagulants Complement activation—anti-

inflammatories . . . ? statins

Guidelines for NSTE-ACS diagnosis and management

Guidelines for NSTE-ACS diagnosis and management

Very complex disease state with broad ranges of risk and a multitude of therapeutic options

Many important and pertinent clinical studies

Information overload!

Need evidence-based guidelines to promote consistency of care and resulting better outcomes

Class I Benefit >>> Risk

Procedure/ Treatment SHOULD be performed/ administered

Class IIa Benefit >> RiskAdditional studies with focused objectives needed

IT IS REASONABLE to perform procedure/administer treatment

Class IIb Benefit ≥ RiskAdditional studies with broad objectives needed; Additional registry data would be helpful

Procedure/Treatment MAY BE CONSIDERED

Class III Risk ≥ BenefitNo additional studies needed

Procedure/Treatment should NOT be per-formed/administered SINCE IT IS NOT HELPFUL AND MAY BE HARMFUL

Early invasive: diagnostic angiography with intent to perform revascularization cath anticipated within 4-24 hours follows a foundation of risk-directed medical therapy

Selectively invasive (or early conservative): invasive evaluation only if optimal medical management fails

Note: from ED perspective, both strategies involve risk-directed, evidence-based medical therapy

duration of therapy after ACS and PCI performed with DES, with 162-325mg ASA for at least 3 months after sirolimus-eluting stent and 6 months after paclitaxel-eluting stent . . . then indefinitely thereafter

75mg daily for at least 12 months (I-B)

CHARISMA showed no net benefit from long-term clopidogrel therapy to patients with cardiac risk factors but no objectively demonstrated CAD

Optimal Management of NSTE ACS ED to Cardiology — A Functional Model

Chest Pain or ACS Committee discusses: Protocols and standing orders Practice variations versus evidence Time to catheterization predictability Reduction of medical errors in ACS care DTB times QI issues (CRUSADE / NRMI / ACTION) Transfers in, transfers out New data: How should it impact our protocols?

Optimal Management of NSTE ACS ED to Cardiology — A Functional Model

ED physicians should be using optimal, evidence-based, guideline-consistent medical therapy for NSTE ACS

ED physicians must work with their colleagues in cardiology to develop pathways and approaches (EDICT for ACS) for proper use of antithrombotic and antiplatelet therapy at all levels

ED physicians should facilitate early invasive management of ACS whenever feasible and appropriate

ED physicians should address issues related to bleeding risk as well as ischemic risk.

A seamless transition of care is most likely to result in good outcomes.

Optimal Management of NSTE ACS ED to Cardiology — Summary and Game Plan

We should be using optimal medical therapy for NSTE ACS in the ED, just as in the CCU or the cath lab.

There must be cross-disciplinary collaboration (EM, CD, IM, HM, CTS, nursing throughout all levels of care) to develop pathways for proper use of antithrombotic and antiplatelet therapy at all levels, to facilitate early invasive management whenever feasible, and to address issues related to bleeding risk as well as ischemic risk.
