The classification of indications for adiagnostic procedure or a specific therapy isexpressed in the standard ACC/ AHA format:
Class I Conditions for which there is evidence and/orgeneral agreement that a given procedure ortreatment is beneficial, useful, and effective.
Class II Conditions for which there is conflicting evidenceand/or a divergence of opinion about the useful-ness/efficacy of a procedure or treatment.
Class IIa Weight of evidence/opinion is in favorof usefulness/efficacy.
Class IIb Usefulness/efficacy is less well established
by evidence/opinion.
Class III Conditions for which there is evidence and/orgeneral agreement that a procedure/treatment isnot useful/effective and in some cases may beharmful.
I. Introduction
his pocket guideline is a distillation of the publica-tion AC C/A H A Guidelin es for th e M an agem en t of
Patients with Acut e Myocardial Infarction. The guidelines
were initially published in the Journal of th e Am ericanCollege of Cardiologyin 1996 (J Am Coll Cardiol 1996;28:1328-428) and updated in September 1999. Therevised text and recommendations are published in the
J Am Coll Cardiol 1999;34:890-911 and Circulation1999;100:1016-1030 (recommendations only).
The full text guidelines incorporating the updates andrevisions are available on the Web sites of both theACC (http://www.acc.org) and the AHA (http://www.americanheart.org) with deleted text indicted by strike-outs and new text presented in highlighted typeface.
This pocket guideline provides rapid prompts forappropriate patient management that is outlined inmuch greater detail in the full-text guidelines. It is notintended as a replacement for understanding thecaveats and rationales carefully stated in the full-textguidelines. Users should consult the full-text documentfor more information.

Algorithm for Initial Assessment andEvaluation of the Patient with Acute Chest Pain
Algorithm for Initial Assessment and
Evaluation of the Patient with Acute ChestPain in the Emergency Department
The em ergency department should be organized t o facilitate the
rapid triage of chest pain pat ients so that the in itial evaluation,obtaining a 12-lead electrocardiogram (ECG ), an d establishing
intravenous access and continuous m onitoring are accomplished
within 10 minutes. The path in the decision tree is determined by
the results of the 12-lead EC G. T he presence of ST-segment eleva-
tion diagnostic of AM I or of presum ptively new bu ndle branch
block (BBB ) suggestive of this diagnosis should lead to th e imm edi-
ate consideration of the suitability of the patient for reperfusion
therapy, which, if indicated, should be initiated within 30 minutes
of the patients arrival. The primary PT CA option is applicable
only in those settings in which it is imm ediately available and can
be performed by highly qualified interven tiona l cardiologists. In
general, patients should not be transferred for angioplasty if fibri-
nolysis is an option. Fibrinolysis is not in dicated in pat ients with
only S T-segmented depression.

Serum Cardiac Markers
CK-MB subforms for Dx within 6 hrs of MI onset
cTnI and cTnT efficient for late Dx of MI
CK-MB subform plus cardiac-specific troponin bestcombination
Do not rely solely on troponins because they remainelevated for 7-14 days and compromise ability to diagnoserecurrent infarction
Enzymatic Criteria forDiagnosis of Myocardial Infarction*
Serial increase, then decrease of plasma CK-MB, with achange >25% between any two values
CK-MB >10-13 U/L or >5% total CK activity
Increase in MB-CK activity >50% between any twosamples, separated by at least 4 hrs
If only a single sample available, CK-MB elevation> twofold
Beyond 72 hrs, an elevation of troponin T or I orLDH-1>LDH-2

Recommendations for theManagement of Patients with ST Elevation
III. Initial Management
All pa ti en ts wi th ST-segm en t eleva tio n on th e el ectroca rdi ogra m shou ld receiv e a sp irin(ASA ). Beta-adrenoreceptor blockers (in the absence of contraindications), and anantithrom bin (p articularly if alteplase/reteplase is u sed for fibrinolytic therapy). W hether heparin is required in patients receiving nonselective fibrinolytic agents remains a matter of
controversy; the small additional risk for intracranial hem orrhage may not be offset by th esurvival benefit afforded by add ing heparin to S K therapy. Patients treated within 1 2 hou rswho are eligible for fibrinolytics should expeditiously receive either fibrinolytic therapy or beconsidered for primar y percutaneous translumina l coronary an gioplasty (PTCA ). PrimaryPTCA is also to be considered when fibrinolytic therapy is absolutely contraindicated.Coronary artery bypass graft (CABG) may be considered if the patient is less than 6 hours from on set of sym pt om s. In divid ua ls t reat ed aft er 12 hour s s hould receiv e t he in it ial m ed-ical therapy noted above and, on an individual basis, may be candidates for reperfusiontherapy or a ngiotensin-converting enzyme (ACE) inhibitors (particularly if left ventricular fu nc tio n is im pa ired ).

Advantages of Fibrinolytic Therapy
More universal access
Shorter time to treatment
Greater clinical trial evidence of:reduction in infarct sizeimprovement of LV function
Results less dependent on physician experience
Lower system cost
Advantages of Primary PTCA
Higher initial reperfusion rates
Lower recurrence rates of ischemia/infarction
Less residual stenosis
Less intracranial bleeding
Defines coronary anatomy and LV function
Utility when fibrinolysis contraindicated
Class IIb Recommendations
1. In patients with AMI who do not present with
ST elevation but who have reduced [less than
TIMI (Thrombolysis in Myocardial Infarction)
grade 2] flow of the infarct-related artery and
when angioplasty can be performed within 12
hrs of onset of symptoms.
Class III Recommendations
1. This classification applies to patients with AMI
who
Undergo elective angioplasty in a noninfarct-related artery at the time of AMI
Are beyond 12 hrs after the onset of symptomsand have no evidence of myocardial ischemia
Have received fibrinolytic therapy and have nosymptoms of myocardial ischemia
Are fibrinolytic-eligible and are undergoingprimary angioplasty by an unskilled operator in alaboratory that does not have surgical capability.

Algorithm for the Management
of Patients with Non-ST Elevation MI
Al l p at ien ts wit hou t ST eleva tio n shou ld be trea ted wi th an
antithrombin and aspirin (ASA). Nitrates should be administered
for recu rren t epi sodes o f a ng ina. Adeq ua te bet a-a dren ocep tor
blockade should then be established; when th is is not possible or
contraindications exist, a calcium antagonist can be considered.
Current data indicate that either an invasive or non-invasive
treatment strategy is suitable for non-ST-elevation A MI p atients.

Pharmacologic Management of Patients with MI
Heparin Recommendations
Class I Recommendations
1. In patients undergoing percutaneous or surgicalrevascularization.
Class IIa Recommendations
1. Intravenously in patients undergoing reperfusion therapywith alteplase/reteplase. See table below for dosing:
Change in Heparin (Unfractionated) Dose
with alteplase/reteplase
1999 1996Recommendations Recommendations
Bolus Dose 60 U/kg 70 U/kg
Maintenance 12 U/kg/hr 15 U/kg/hr
Maximum 4000 U bolus None1000 U/h if >70 kg
aPTT 1.5-2.0 x control 1.5-2.0 x control(50-70 sec) for 48 hrs (50-70sec) for 48 hrs
2. Intravenous unfractionated heparin (UFH) or low molecu-lar weight heparin (LMWH) subcutaneously for patients withnon-ST elevation MI.
3. Subcutaneous UFH (eg, 7,500 U b.i.d.) or low molecularweight heparin (eg, enoxaparin 1 mg/kg b.i.d.) in all patientsnot treated with fibrinolytic therapy who do not have a con-traindication to heparin. In patients who are at high risk for
systemic emboli (large or anterior MI, AF, previous embolus,or known LV thrombus), intravenous heparin is preferred.
4. Intravenously in patients treated with nonselective fibri-nolytic agents (streptokinase, anistreplase, urokinase) who areat high risk for systemic emboli (large or anterior MI, AF, pre-vious embolus, or known LV thrombus).
Class IIb Recommendations
1. In patients treated with nonselective fibrinolytic agents,not at high risk, subcutaneous heparin, 7,500 U to 12,500 Utwice a day until completely ambulatory.
Class III Recommendations
1. Routine intravenous heparin within 6 hrs to patientsreceiving a nonselective fibrinolytic agent (anistreplase, strep-tokinase, urokinase) who are not at high risk for systemicembolism.
GP IIb/ IIIa InhibitorsNew Recommendations
Class IIa Recommendations
For use in patients experiencing an MI without ST segmentelevation who have some high-risk features and/or refractoryischemia, provided they do not have a contraindication dueto a bleeding risk.
