  20. 20. Variables Used in the TIMI Risk Score • Age ≥ 65 years =1 point • At least 3 risk factors for CAD =1 point • Prior coronary stenosis of ≥ 50% =1 point • ST-segment deviation on ECG presentation =1 point • At least 2 anginal events in prior 24 hours =1 point • Use of aspirin in prior 7 days =1 point • Elevated serum cardiac biomarkers =1 point The TIMI risk score is determined by the sum of the presence of the above 7 variables at admission. 1 point is given for each variable. Primary coronary stenosis of 50% or more remained relatively insensitive to missing information and remained a significant predictor of events. Antman EM, et al. JAMA 2000;284:835–42.

  24. 24. UA/NSTEMI Hospital Care Let’s Start with the Basics! Assuming the NSTEMI has been our diagnosis
  25. 25. ACC/AHA Guidelines ACS Treatment Overview: UA/NSTEMI Diagnosis of UA or NSTEMI is likely or definite Aspirin or clopidogrel (if patient is aspirin intolerant) Initial conservative management Initial invasive management Medical therapy Evaluation of LV Function in pt with ischemia aIf Diagnostic angiography PCI or CABGa Long-term medical management: Clopidogrel, aspirin, β-blocker, ACEI, statin possible, clopidogrel should be withheld for 5-7 days prior to the procedure. Anderson JL, et al. Circulation. 2007;116:803-877.
  26. 26. Selection of Initial Treatment Wright RS et al. Circ 2011;123;2022-2060.
  27. 27. Early Treatment Class I Indications     Bed rest with continuous ECG Monitoring O2 therapy if saturation <90%, respiratory distress, or other high-risk features for hypoxemia SL NTG 0.4 mg q5min x3 then assessment of need for IV NTG IV NTG indicated first 48 hours for treatment of persistent ischemia, CHF or HTN; should not preclude Rx with beta-blockers or ACE Wright RS et al. Circ 2011;123;2022-2060.
  28. 28. Early Treatment Class I Indications   Oral Beta-Blocker in first 24 hours for pt who do not have  Signs of CHF  Low out-put state  Increased risk of cardiogenic shock  Contraindication to Beta blockers/heart block/COPD If Beta-Blockers are contraindicated a nondihydropyridine calcium channel blocker may be used if no LV dysfunction Wright RS et al. Circ 2011;123;2022-2060.
  29. 29. Early Treatment (Cont.) ACE inhibitor within 24 hours with pulmonary congestion or LVEF < 40% in the absence of hypotension or contraindication  Because of the increased risk of mortality, reinfarction, HTN, CHF, and myocardial rupture NSAIDS except for ASA should be discontinued at presentation Class II indications:  It is reasonable to admin O2 to all UA/NSTEMI pts in first 6 hours. IIa  Morphine (1-5 mg IV) remains Class I for STEMI although may increase adverse events in UA/NSTEMI (1,2)  It is reasonable to administer morphine sulfate IV if there is uncontrolled ischemic Chest Pain despite NTG.

  30. 30. Rx for all NSTEMI Early Hospital Care 2011 Focused update Antiplatelet therapy   ASA should be administered to USA/NSTEMI as soon as possible after hospital presentation and continued indefinitely (LOE A) Clopidogrel (loading dose followed by maintenance dose) should be administered to USA/NSTEMI patients who are unable to take ASA because of hypersensitivity or major gastrointestinal intolerance (LOE B) Wright RS et al. J Am Coll Cardio 2011; 57;e215-e367
  31. 31. Look who is sleeping
  32. 32. Conservative Rx Hospital Care 2011 Focused update Antiplatelet therapy  For USA/NSTEMI patients in whom an initial conservative strategy is selected clopidogrel (loading dose followed by maintenance dose) should be added to ASA and anticoagulant therapy as soon as possible after admission and administered for at least 1 month and ideally up to 1 year Wright RS et al. J Am Coll Cardio 2011; 57;e215-e367
  33. 33. Conservative Rx Hospital Care Initial Conservative Strategy: Anticoagulant Therapy   Anticoagulant therapy should be added to antiplatelet therapy in UA/NSTEMI patients as soon as possible after presentation. For patients in whom a conservative strategy is selected, regimens using either enoxaparin* or UFH (LOE A) or fondaparinux (LOE: B) have established efficacy.  In patients in whom a conservative strategy is selected and who have an increased risk of bleeding, fondaparinux is preferable. Wright RS et al. J Am Coll Cardio 2011; 57;e215-e367 *Limited data are available for the use of other lowmolecular-weight heparins (LMWHs), e.g., dalteparin.
