FIRE: Focused Initial Rapid Evaluation

A Focused Initial Rapid Evaluation (FIRE) should be performed to identify patients in need of immediate intervention.

Boxes in the salmon color signify that an urgent management is needed.

Abbreviations:

Identify cardinal findings that increase the pretest probability of chest pain ❑

Does the patient have any of the findings that require urgent management? ❑ Tachycardia ❑ Hypotension ❑ Severe dyspnea ❑ ❑

Yes

No

❑ Immediately order an ECG

ECG findings

Complete Diagnostic Approach

A complete diagnostic approach should be carried out after a focused initial rapid evaluation is conducted and following initiation of any urgent intervention.

Abbreviations:

Characterize the symptoms: ❑ ❑ ❑ ❑ ❑ Activity prior to ❑

Inquire about past medical history: ❑ Previous episodes ❑ Cardiovascular disease ❑ Neurological diseases

Identify possible triggers:

Examine the patient: Vitals ❑ Heart rate ❑ Blood pressure ❑ Respiratory rate Cardiovascular Respiratory ❑ Rales (suggestive of HF) Neurologic

Order labs and tests: ❑ EKG (most important initial test) ❑ Electrolytes ❑ Glucose (rule out hypoglycemia) ❑ ABG

Order imaging studies: ❑ Echocardiography

Treatment

Shown below is an algorithm summarizing the therapeutic approach to chest pain based on the

Abbreviations:

Do's

• Consider a tilt test:
  • To differentiate between reflex syncope and orthostatic hypotension (Class IIa; Level of Evidence: C)
  • If syncope is due to a psychiatric disease (Class IIb; Level of Evidence: C)
  • To differenciate syncope with jerking movements from epilepsy (Class IIb; Level of Evidence: C)
  • If syncope happened after standing up from a seated position due to possible orthostatic hypotension(Class IIb; Level of Evidence: C)
• Consider implantable loop recorder before cardiac pacing in patients with suspected or confirmed reflex syncope presenting with frequent or traumatic syncopal episodes.
• Perform exercise testing in patients who experience syncope during or after exertion (Class I; Level of Evidence: C).

Don'ts

• Don't perform carotid sinus massage in patients with previous TIA or stroke within the past 3 months and in patients with carotid sinus bruits unless carotid sinus doppler studies excluded significant stenosis (Class III; Level of Evidence: C).
• Don't perform tilt testing for the assessment of response to treatment. (Class III; Level of Evidence: B).
• Don't perform isoproterenol tilt test in patients with ischemic heart disease (Class III; Level of Evidence: C).
• Don't use adenosine stress test as a diagnostic test to select patients for cardiac pacing due to the lack of correlation with spontaneous syncope (Class III; Level of Evidence: B).
• Don't perform electrophysiologic study if there is already indication for implantable cardioverter defibrillator in patients with ischemic heart disease with suspected arrhythmic cause.
• Don't perform electrophysiologic study in patients with normal ECG, no heart disease and no palpitations unless non-syncopal LOC is suspected (Class III; Level of Evidence: B).
• Don't give beta blockers for patients with reflex syncope (Class III; Level of Evidence: A).
