Definition

ST elevation myocardial infarction (STEMI) is a syndrome defined by symptoms of myocardial ischemia (sudden chest pain and pressure, shortness of breath) associated with persistent ECG ST elevation and subsequent release of cardiac enzymes.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. STEMI is a life-threatening condition and must be treated as such irrespective of the causes.

Common Causes

Management

Diagnostic Approach

Shown below is an algorithm summarizing the diagnostic approach to STEMI based on the 2013 ACCF/AHA Guideline for the Management of ST-Elevation Myocardial Infarction[1]


 
 
 
 
 
Characterize the symptoms:

Chest pain

❑ Sudden onset
❑ Described as a sensation of tightness, pressure, or squeezing
❑ Radiation to the jaw or left arm
❑ No relief with medications or rest
❑ Worse with time
❑ Shortness of breath (Dyspnea)

Diaphoresis
Light-headedness

Nausea and/or vomiting
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Obtain a detailed history:

❑ Age
❑ Previous MI
❑ Previous PCI or CABG
❑ Cardiac risk factors:

Hypertension
Diabetes
Hypercholesterolemia
Smoking
Obesity
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Examine the patient:

❑ Measure the blood pressure
❑ Measure the heart rate
❑ Auscultate the heart searching for murmurs
❑ Search for signs of CHF

❑ Decreased air entry in the lungs
❑ Edema in the extremities
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Rule out life threatening alternative diagnoses:

Aortic dissection
Pulmonary embolism
Cardiac tamponade
Tension pneumothorax

Esophageal rupture
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Order labs and tests:
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
EKG
❑ New ST elevation at the J point in at least 2 contiguous leads of 2 mm (0.2 mV) in men or 1.5 mm (0.15 mV) in women in leads V2–V3 and/or of 1 mm (0.1 mV) in other contiguous chest leads or the limb leads
❑ For EKG examples click here
 
Cardiac Enzymes
Troponin I (preferred biomarker)
CK-MB
 
Other labs:

Creatinine
Glucose

Hemoglobin
 
 

Therapeutic Apporach

Shown below is an algorithm depicting the therapeutic approach to STEMI based on the 2013 ACCF/AHA Guideline for the Management of ST-Elevation Myocardial Infarction.[1]

 
 
 
 
 
 
Initial Treatment
❑ Administer 300 mg aspirin[2]

❑ Administer oxygen in patients with saturation <90%[3]
❑ Administer sublingual nitroglycerine, (0.4-0.8 mg)[4]
❑ Administer morphine IV (initial dose 2-4 mg with increments of 2-8 mg every 5 to 15 minutes)
❑ Administer beta-blockers (unless contraindicated)[5] [6]
❑ Administer statins (atorvastatin, 80 mg)[7]
❑ Administer antithrombotic treatment

Fondaparinux, or
UFH in case of renal failure[8]
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Determine the risk of adverse coronary event:

TIMI Score, or
HEART Risk Score, or

GRACE Risk Score
