Acute Coronary Syndrome: Out-of-Hospital Evaluation and Management

Area of Science:

• Family Medicine
• Cardiology
• Emergency Medicine

Background:

• Acute coronary syndrome (ACS) diagnosis in family medicine presents unique challenges.
• Uncommon presentation and atypical symptoms complicate early identification in office settings.

Purpose of the Study:

• To outline an approach for identifying and managing potential acute coronary syndrome (ACS) in family medicine.
• To guide family physicians in evaluating patients with symptoms suggestive of ACS.

Main Methods:

• Review of patient symptoms, risk factor assessment, and electrocardiogram (ECG) interpretation.
• Guidance on emergency medical services (EMS) transport for typical and atypical ACS symptoms.
• Consideration of patient risk factors (age, sex, race, comorbidities) when ECG results are nondiagnostic.

Main Results:

• Typical ACS symptoms warrant immediate EMS transport, with pre-transport aspirin and nitroglycerin if not contraindicated.
• Atypical symptoms with concerning ECGs also require EMS transport.
• Atypical symptoms with nondiagnostic ECGs necessitate transport if ACS risk factors are present.

Conclusions:

• Family physicians must be vigilant for ACS, utilizing symptom review, risk factors, and ECGs.
• Rapid EMS transport is key for suspected ACS, especially with typical symptoms or risk factors.
• Remote or rural practices should ensure ECG capability and consider point-of-care troponin testing for enhanced ACS evaluation.
