Changing the Calculation Assessing Adherence to Guidelines Anderson HV, Bach RG, J Am Coll Cardiol 2005;46: We need to invert the current equation to calculate an opportunity score for ACS patients rather than a risk score. Patients with higher baseline risks, such as the elderly, would have higher opportunity scores for benefit, even allowing for some of the greater risks from the treatment.

Big Picture: Early Invasive Vs. Initial Conservative Therapy An early invasive strategy (i.e., diagnostic angiography with intent to perform revascularization) is indicated in initially stabilized UA/NSTEMI patients (without serious comorbidities or contraindications to such procedures) who have an elevated risk for clinical events. In initially stabilized patients, an initially conservative (i.e., a selectively invasive) strategy may be considered as a treatment strategy for UA/NSTEMI patients (without serious comorbidities or contraindications to such procedures) who have an elevated risk for clinical events, including those who are troponin positive. The decision to implement an initial conservative (vs. initial invasive) strategy in these patients may be made by considering physician and patient preference. Big Picture: Early Invasive Vs.

In general, based on my interpretation of the current evidence for selecting anticoagulation therapy in ACS patients, therapy is best guided by: A. Ischemic risk (reduction of ischemic endpoints) B. Bleeding risk (reduction of bleeding endpoints) C. Balance of ischemic and bleeding risk, and selection of a strategy that optimizes net clinical benefit (optimizes aggregate reduction of both ischemic and bleeding endpoints) * Concluding Questions

1) How do ED specialists incorporate new streams of care for NSTEMI introduced by Year 2007 ACC/AHA Guidelines for NSTEMI - Bivaliridion for initial invasive strategy? Fondaprinux for initial conservative therapy? 2) How do new guidelines affect clopidogrel treatment at front lines of ED care? 3) How do ED specialists and cardiologists synchronize on new GLs and newly introduced options? 4) Questions * Discussion Points
