13
Identification of Patients at Risk of STEMI
The presence and status of control of major risk
factors for CHD should be evaluated approximately
every 3 to 5 years.
10-year risk of developing symptomatic CHD should
be calculated for all patients with 2 major
risk factors to assess the need for primary
prevention strategies.
14
Identification of Patients at Risk of STEMI
Patients with established CHD or a CHD risk
equivalent (diabetes mellitus, chronic kidney
disease, gt 20 10-year Framingham risk) should be
identified for secondary prevention.
15
Onset of STEMI
  • ACC/AHA Guidelines for the Management of Patients
    with
  • ST-Elevation Myocardial Infarction

16
Patient Education for Early Recognition and
Response to STEMI
Patients should understand their risk of STEMI
and how to recognize symptoms of STEMI.
Patients should understand the advisability of
calling 9-1-1 if symptoms are unimproved or
worsening after 5 minutes.
17
ACT in TIME
If you have any heart attack symptoms, CALL
9-1-1 immediately. Dont wait for more than a
few minutes 5 at most to call 9-1-1.
http//www.nhlbi.nih.gov/actintime/index.htm.
Accessed December 20, 2004.
18
Patient Education for Early Recognition and
Response to STEMI
Healthcare providers should instruct patients
previously prescribed nitroglycerin (NTG) on use
for chest discomfort or pain and to call 9-1-1 if
symptoms do not improve or worsen 5 minutes after
ONE sublingual NTG dose. ( Nitroglycerin Dose
0.4 mg sublingually)
19
Prehospital Chest Pain Evaluation and Treatment
Prehospital EMS providers should administer 162
to 325 mg of aspirin (chewed) to chest pain
patients suspected of having STEMI unless
contraindicated or already taken by the patient.
Although some trials have used enteric-coated
aspirin for initial dosing, more rapid buccal
absorption occurs with nonenteric-coated
formulations.
It is reasonable for all 9-1-1 dispatchers to
advise patients without a history of aspirin
allergy who have symptoms of STEMI to chew
aspirin (162 to 325 mg) while awaiting arrival of
prehospital EMS providers. Although some trials
have used enteric-coated aspirin for initial
dosing, more rapid buccal absorption occurs with
nonenteric-coated formulations.

Prehospital Issues
  • ACC/AHA Guidelines for the Management of Patients
    with
  • ST-Elevation Myocardial Infarction

23
Prehospital Issues
  • All public safety first responders trained and
    equipped to provide early defibrillation with
    AEDs.
  • Prehospital aspirin 162 to 325 mg (chewed)
    administration
  • By prehospital providers
  • Advice by dispatchers

24
Prehospital Issues
  • Prehospital 12-lead ECG by ACLS
  • Prehospital fibrinolysis
  • Reperfusion checklist by ACLS providers that is
    relayed with the ECG to a predetermined medical
    control facility and/or receiving hospital

25
Prehospital Issues
Prehospital destination protocols Patients with
STEMI who have cardiogenic shock and are lt75 yrs
old should be brought immediately or secondarily
transferred to facilities capable of cardiac
catheterization and rapid revascularization with
18 hrs of shock
26
Prehospital Issues
Prehospital destination protocols Patients with
STEMI who have contraindications to fibrinolytic
therapy should be brought immediately or
secondarily transferred promptly
(primary-receiving hospital door-to-departure
time less than 30 min.) to facilities capable of
cardiac catheterization and rapid
revascularization

  • Patients receiving fibrinolysis should be
    risk-stratified to identify need for further
    revascularization with percutaneous coronary
    intervention (PCI) or coronary artery bypass
    graft surgery (CABG).
  • All patients should receive late hospital care
    and secondary prevention of STEMI.

34
Electrocardiogram
If the initial ECG is not diagnostic of STEMI,
serial ECGs or continuous ST-segment monitoring
should be performed in the patient who remains
symptomatic or if there is high clinical
suspicion for STEMI.
35
Electrocardiogram
Show 12-lead ECG results to emergency physician
within 10 minutes of ED arrival in all patients
with chest discomfort (or anginal equivalent) or
other symptoms of STEMI.
In patients with inferior STEMI, ECG leads should
also be obtained to screen for right ventricular
infarction.
36
Laboratory Examinations
Laboratory examinations should be performed as
part of the management of STEMI patients, but
should not delay the implementation of
reperfusion therapy.
  • Serum biomarkers for cardiac damage
  • Complete blood count (CBC) with platelets
  • International normalized ratio (INR)
  • Activated partial thromboplastin time (aPTT)
  • Electrolytes and magnesium
  • Blood urea nitrogen (BUN)
  • Creatinine
  • Glucose
  • Complete lipid profile

37
Biomarkers of Cardiac Damage
Cardiac-specific troponins should be used as the
optimum biomarkers for the evaluation of patients
with STEMI who have coexistent skeletal muscle
injury. For patients with ST elevation on the
12-lead ECG and symptoms of STEMI, reperfusion
therapy should be initiated as soon as possible
and is not contingent on a biomarker assay.

39
Imaging
Patients with STEMI should have a portable chest
X-ray, but this should not delay implementation
of reperfusion therapy (unless a potential
contraindication is suspected, such as aortic
dissection). Imaging studies such as a high
quality portable chest X-ray, transthoracic
and/or transesophageal echocardiography, and a
contrast chest CT scan or an MRI scan should be
used for differentiating STEMI from aortic
dissection in patients for whom this distinction
is initially unclear.
40
Oxygen
Supplemental oxygen should be administered to
patients with arterial oxygen desaturation (SaO2
lt 90). It is reasonable to administer
supplemental oxygen to all patients with
uncomplicated STEMI during the first 6 hours.
41
Nitroglycerin
Patients with ongoing ischemic discomfort should
receive sublingual NTG (0.4 mg) every 5 minutes
for a total of 3 doses, after which an assessment
should be made about the need for intravenous
NTG. Intravenous NTG is indicated for relief
of ongoing ischemic discomfort that responds to
nitrate therapy, control of hypertension, or
management of pulmonary congestion.
42
Nitroglycerin
Nitrates should not be administered to patients
with Nitrates should not be administered
to patients who have received a phosphodiesterase
inhibitor for erectile dysfunction within the
last 24 hours (48 hours for tadalafil).
  • systolic pressure lt 90 mm Hg or to 30 mm Hg
    below baseline
  • severe bradycardia (lt 50 bpm)
  • tachycardia (gt 100 bpm) or
  • suspected RV infarction.

43
Analgesia
Morphine sulfate (2 to 4 mg intravenously with
increments of 2 to 8 mg intravenously repeated at
5 to 15 minute intervals) is the analgesic of
choice for management of pain associated with
STEMI.
44
Aspirin
Aspirin should be chewed by patients who have not
taken aspirin before presentation with STEMI. The
initial dose should be 162 mg (Level of Evidence
A) to 325 mg (Level of Evidence C)
Although some trials have used enteric-coated
aspirin for initial dosing, more rapid buccal
absorption occurs with nonenteric-coated
formulations.
45

Beta-Blockers
Oral beta-blocker therapy should be administered
promptly to those patients without a
contraindication, irrespective of concomitant
fibrinolytic therapy or performance of primary
PCI. It is reasonable to administer
intravenous beta-blockers promptly to STEMI
patients without contraindications, especially if
a tachyarrhythmia or hypertension is present.

47
Reperfusion
  • Given the current literature, it is not possible
    to say definitively that a particular reperfusion
    approach is superior for all pts, in all clinical
    settings, at all times of day
  • The main point is that some type of reperfusion
    therapy should be selected for all appropriate
    pts with suspected STEMI
  • The appropriate timely use of some reperfusion
    therapy is likely more important than the choice
    of therapy

48
Reperfusion
The medical system goal is to facilitate rapid
recognition and treatment of patients with STEMI
such that door-to- needle (or medical
contactto-needle) time for initiation of
fibrinolytic therapy can be achieved within 30
minutes or that door-to-balloon (or medical
contactto- balloon) time for PCI can be kept
within 90 minutes.

  • Data span 1015 years
  • Selection bias of pts enrolled
  • 2 mortality benefit with PCI depends on lytic

  • Composite endpoint is driven by reMI potential
    biases against lytic arms Hard to diagnose
    peri-PCI MI UFH used in lytic arms--? Better

  • Fibrinolysis generally preferred
  • Early presentation ( 3 hours from symptom
  • onset and delay to invasive strategy)
  • Invasive strategy not an option
  • ? Cath lab occupied or not available
  • ? Vascular access difficulties ? No
    access to skilled PCI lab
  • Delay to invasive strategy
  • ? Prolonged transport ? Door-to-balloon
    more than 90 minutes
  • ? gt 1 hour vs fibrinolysis (fibrin-specific
    agent) now

61
Reperfusion Options for STEMI Patients Step 2
Select Reperfusion Treatment.
If presentation is lt 3 hours and there is no
delay to an invasive strategy, there is no
preference for either strategy.
  • Invasive strategy generally preferred
  • Skilled PCI lab available with surgical backup
    ? Door-to-balloon lt 90 minutes
  • High Risk from STEMI ? Cardiogenic shock,
    Killip class 3
  • Contraindications to fibrinolysis, including
  • increased risk of bleeding and ICH
  • Late presentation ? gt 3 hours from symptom
    onset
  • Diagnosis of STEMI is in doubt

62

    increasing delay PCI Fibrin spec lytic with
    60 min delay RR 1.08 for every 30 min from
    onset of sx The earlier patient is seen PCI
    Lysis in lt 3 h from sx
  • Outcomes with PCI are influenced by time of day
    and operator/institution volume and experience
  • Trials of transfer for PCI Had very short
    transport and D-B times PCI mortality higher
    than prehospital lysis in pts treated early
    (2h)

JACC 200444 671Circ 2004110 588
63
Fibrinolysis
In the absence of contraindications, fibrinolytic
therapy should be administered to STEMI patients
with symptom onset within the prior 12 hours.
In the absence of contraindications, fibrinolytic
therapy should be administered to STEMI patients
with symptom onset within the prior 12 hours and
new or presumably new left bundle branch block
(LBBB).
64
Fibrinolysis
In the absence of contraindications, it is
reasonable to administer fibrinolytic therapy to
STEMI patients with symptom onset within the
prior 12 hours and 12-lead ECG findings
consistent with a true posterior MI.
In the absence of contraindications, it is
reasonable to administer fibrinolytic therapy to
patients with symptoms of STEMI beginning in the
prior 12 to 24 hours who have continuing ischemic
symptoms and ST elevation gt 0.1 mV in 2
contiguous precordial leads or 2 adjacent limb
leads.
65
Fibrinolysis
Fibrinolytic therapy should not be administered
to asymptomatic patients whose initial symptoms
of STEMI began more than 24 hours earlier.
Fibrinolytic therapy should not be administered
to patients whose 12-lead ECG shows only
ST-segment depression, except if a true posterior
MI is suspected.

Primary PCI for STEMI General Considerations
  • Patient with STEMI (including posterior MI) or MI
    with new or presumably new LBBB
  • PCI of infarct artery within 12 hours of symptom
    onset
  • Balloon inflation within 90 minutes of
    presentation
  • Skilled personnel available (individual performs
    gt 75 procedures per year)
  • Appropriate lab environment (lab performs gt 200
    PCIs/year of which at least 36 are primary PCI
    for STEMI)
  • Cardiac surgical backup available

68
Primary PCI for STEMI Specific Considerations
Medical contactto-balloon or door-to-balloon
should be within 90 minutes.
PCI preferred if gt 3 hours from symptom onset.
Primary PCI should be performed in patients with
severe congestive heart failure (CHF) and/or
pulmonary edema (Killip class 3) and onset of
symptoms within 12 hours.
69
Primary PCI for STEMI Specific Considerations
Primary PCI should be performed in patients less
than 75 years old with ST elevation or LBBB who
develop shock within 36 hours of MI and are
suitable for revascularization that can be
performed within 18 hours of shock.
70
Primary PCI for STEMI Specific Considerations
Primary PCI is reasonable in selected patients 75
years or older with ST elevation or LBBB who
develop shock within 36 hours of MI and are
suitable for revascularization that can be
performed within 18 hours of shock.
71
Primary PCI for STEMI Specific Considerations
It is reasonable to perform primary PCI for
patients with onset of symptoms within the prior
12 to 24 hours and 1 or more of the following a.
Severe CHF b. Hemodynamic or electrical
instability c. Persistent ischemic symptoms.
72

Rescue PCI
Rescue PCI should be performed in patients less
than 75 years old with ST elevation or LBBB who
develop shock within 36 hours of MI and are
suitable for revascularization that can be
performed within 18 hours of shock. Rescue PCI
should be performed in patients with severe CHF
and/or pulmonary edema (Killip class 3) and onset
of symptoms within 12 hours.
73

Rescue PCI
Rescue PCI is reasonable for selected patients 75
years or older with ST elevation or LBBB or who
develop shock within 36 hours of MI and are
suitable for revascularization that can be
performed within 18 hours of shock. It is
reasonable to perform rescue PCI for patients
with one or more of the following a.
Hemodynamic or electrical instability b.

PCI for Cardiogenic Shock
Primary PCI is recommended for patients less than
75 years with ST elevation or LBBB or who develop
shock within 36 hours of MI and are suitable for
revascularization that can be performed within 18

PCI After Fibrinolysis
  • In patients whose anatomy is suitable, PCI should
    be
  • performed for the following
  • Objective evidence of recurrent MI
  • Moderate or severe spontaneous/provocable
    myocardial ischemia during recovery from STEMI
  • Cardiogenic shock or hemodynamic instability.

79

PCI After Fibrinolysis
It is reasonable to perform routine PCI in
patients with left ventricular ejection fraction
(LVEF) 0.40, CHF, or serious ventricular
arrhythmias.
It is reasonable to perform PCI when there is
documented clinical heart failure during the
acute episode, even though subsequent evaluation
shows preserved LV function (LVEF gt 0.40).
Routine PCI might be considered as part of an
invasive strategy after fibrinolytic therapy.
80

Assessment of Reperfusion
  • It is reasonable to monitor the pattern of ST
    elevation,
  • cardiac rhythm and clinical symptoms over the 60
    to 180
  • minutes after initiation of fibrinolytic therapy.
  • Noninvasive findings suggestive of reperfusion
    include
  • Relief of symptoms
  • Maintenance and restoration of hemodynamic and/or
    electrical instability
  • Reduction of 50 of the initial ST-segment
    elevation pattern on follow-up ECG 60 to 90
    minutes after initiation of therapy.

81
Ancillary Therapy to Reperfusion
  • Unfractionated heparin (UFH) should be given
  • intravenously in
  • Patients undergoing PCI or surgical
    revascularization
  • After alteplase, reteplase, tenecteplase
  • After streptokinase, anistreplase, urokinase in
    patients at high risk for systemic emboli.

82

Ancillary Therapy to Reperfusion
Platelet counts should be monitored daily in
patients taking UFH.
Low molecular-weight heparin (LMWH) might be
considered an acceptable alternative to UFH in
patients less than 75 years who are receiving
fibrinolytic therapy in the absence of
significant renal dysfunction. Enoxaparin used
with tenecteplase is the most comprehensively
studied.
83

Aspirin
A daily dose of aspirin (initial dose of 162 to
325 mg orally maintenance dose of 75 to 162 mg)
should be given indefinitely after STEMI to all
patients without a true aspirin allergy.
84

Thienopyridines
In patients for whom PCI is planned, clopidogrel
should be started and continued
  • 1 month after bare-metal stent
  • 3 months after sirolimus-eluting stent
  • 6 months after paclitaxel-eluting stent
  • Up to 12 months in absence of high risk for
    bleeding.

85

Thienopyridines
In patients taking clopidogrel in whom CABG is
planned, the drug should be withheld for at least
5 days, and preferably for 7 days, unless the
urgency for revascularization outweighs the risk
of excessive bleeding.
86

Thienopyridines
Clopidogrel is probably indicated in patients
receiving fibrinolytic therapy who are unable to
take aspirin because of hypersensitivity or
gastrointestinal intolerance.
87

Glycoprotein IIb/IIIa Inhibitors
It is reasonable to start treatment with
abciximab as early as possible before primary PCI
(with or without stenting) in patients with STEMI.
Treatment with tirofiban or eptifibatide may be
considered before primary PCI (with or without
stenting) in patients with STEMI.

An intravenous ACE inhibitor should not be given
to patients within the first 24 hours of STEMI
because of the risk of hypotension (possible
exception refractory hypotension).
94

Strict Glucose Control During STEMI
An insulin infusion to normalize blood glucose is
recommended for patients and complicated courses.
It is reasonable to administer an insulin
infusion to normalize blood glucose even in
patients with an uncomplicated course.

  • ST-Elevation Myocardial Infarction

116
Goals Recommendations
  • Assess tobacco use.
  • Strongly encourage patient and family to stop
    smoking and to avoid secondhand smoke.
  • Provide counseling, pharmacological therapy
    (including nicotine replacement and bupropion),
    and formal smoking cessation programs as
    appropriate.

Smoking Goal Complete Cessation
117
Goals Recommendations
If blood pressure is 120/80 mm Hg or
greater Initiate lifestyle modification
(weight control, physical activity, alcohol
moderation, moderate sodium restriction, and
emphasis on fruits, vegetables, and low-fat dairy
products) in all patients. If blood pressure is
140/90 mm Hg or greater or 130/80 mm Hg or
greater for individuals with chronic kidney
disease or diabetes Add blood
pressure-reducing medications, emphasizing the
use of beta-blockers and inhibitors of the
renin-angiotensin-aldosterone system.
Blood pressure control Goal lt 140/90 mm Hg or
lt130/80 mm Hg if chronic kidney disease or
diabetes
118
Goals Recommendations
  • Assess risk, preferably with exercise test, to
    guide prescription.
  • Encourage minimum of 30 to 60 minutes of
    activity, preferably daily but at least 3 or 4
    times weekly (walking, jogging, cycling, or other
    aerobic activity) supplemented by an increase in
    daily lifestyle activities (e.g., walking breaks
    at work, gardening, household work).
  • Cardiac rehabilitation programs are recommended
    for patients with STEMI.

Physical activity Minimum goal 30 minutes 3 to
4 days per week Optimal daily
119
Goals Recommendations
  • Start dietary therapy in all patients (lt 7 of
    total calories as saturated fat and lt 200 mg/d
    cholesterol). Promote physical activity and
    weight management. Encourage increased
    consumption of omega-3 fatty acids.
  • Assess fasting lipid profile in all patients,
    preferably within 24 hours of STEMI. Add drug
    therapy according to the following guide

Lipid management (TG less than 200
mg/dL) Primary goal LDL-C ltlt than 100 mg/dL
LDL-C lt 100 mg/dL (baseline or on
treatment) Statins should be used to lower
LDL-C. LDL-C 100 mg/dL (baseline or
on treatment) Intensify LDL-Clowering therapy
with drug treatment, giving preference to statins.
120
If TGs are 150 mg/dL or HDL-C is lt 40
mg/dL Emphasize weight management and physical
activity. Advise smoking cessation. If TG is 200
to 499 mg/dL After LDL-Clowering therapy,
consider adding fibrate or niacin. If TG is
500 mg/dL Consider fibrate or niacin before
LDL-Clowering therapy. Consider omega-3 fatty
acids as adjunct for high TG.
Lipid management (TG 200 mg/dL or
greater) Primary goal NonHDL-C ltlt 130 mg/dL
121
Weight management Goal BMI 18.5 to 24.9
kg/m2 Waist circumference Women lt 35 in. Men
lt 40 in.
Calculate BMI and measure waist circumference as
part of evaluation. Monitor response of BMI and
waist circumference to therapy. Start weight
management and physical activity as appropriate.
Desirable BMI range is 18.5 to 24.9 kg/m2. If
waist circumference is 35 inches in women or
40 inches in men, initiate lifestyle changes and
treatment strategies for metabolic syndrome.
122
Goals Recommendations
Appropriate hypoglycemic therapy to achieve
near-normal fasting plasma glucose, as indicated
by HbA1c. Treatment of other risk factors (e.g.,
physical activity, weight management, blood
pressure, and cholesterol management).
Diabetes management Goal HbA1c lt 7
123
Goals Recommendations
  • In the absence of contraindications, start
    aspirin 75 to 162 mg/d and continue indefinitely.
  • If aspirin is contraindicated, consider
    clopidogrel 75 mg/day or warfarin.
  • Manage warfarin to INR 2.5 to 3.5 in post-STEMI
    patients when clinically indicated or for those
    not able to take aspirin or clopidogrel.

Antiplatelet agents/ anticoagulants
124
Goals Recommendations
Renin-Angiotensin-Aldosterone System Blockers
ACE inhibitors in all patients indefinitely
start early in stable, high-risk patients (ant.
MI, previous MI, Killip class 2 S3 gallop,
rales, radiographic CHF, LVEF lt 0.40).
Angiotensin receptor blockers in patients who
are intolerant of ACE inhibitors and with either
clinical or radiological signs of heart failure
or LVEF lt 0.40. Aldosterone blockade in patients
without significant renal dysfunction or
hyperkalemia who are already receiving
therapeutic doses of an ACE inhibitor, have LVEF
0.40, and have either diabetes or heart failure.
125
Goals Recommendations
Start in all patients. Continue indefinitely.
Observe usual contraindications.

estrogen plus progestin at the time of STEMI
should not continue hormone therapy. However,
women who are beyond 1 to 2 years after
initiation of hormone therapy who wish to
continue such therapy for another compelling
indication should weigh the risks and benefits.

Antioxidants
Antioxidant vitamins such as vitamin E and/or
vitamin C supplements should not be prescribed to
patients recovering from STEMI to prevent
cardiovascular disease.
131

Psychosocial Impact of STEMI
The psychosocial status of the patient should be
evaluated, including inquiries regarding symptoms
of depression, anxiety, or sleep disorders and
the social support environment.
Treatment with cognitive-behavioral therapy and
selective serotonin reuptake inhibitors can be
useful for STEMI patients with depression that
occurs in the year after hospital discharge.
132

Cardiac Rehabilitation
Cardiac rehabilitation/secondary prevention
programs, when available, are recommended for
patients with STEMI, particularly those with
multiple modifiable risk factors and/or those
moderate- to high-risk patients in whom
supervised exercise training is warranted.
