A 62-year-old female with a history of hypertension and diabetes presents with discomfort in her jaw and left arm that began an hour ago. She denies typical chest pain. Her ECG shows ST depression in leads V4-V6 and T wave inversions in leads II, III, aVF. Cardiac markers are pending. Which of the following is the most appropriate initial treatment priority?
- APrepare for transcutaneous pacing
- BAdminister aspirin and transport to a PCI-capable facility
- CAdminister immediate thrombolytic therapy
- DAdminister Adenosine 6 mg IV push
Show answer & explanationAnswer & explanation
Correct answer: B. Administer aspirin and transport to a PCI-capable facility
The patient's symptoms (atypical jaw/arm discomfort) and ECG findings (ST depression, T wave inversions) are highly suspicious for an Non-ST Elevation Myocardial Infarction (NSTEMI) or Unstable Angina. Initial management includes aspirin to inhibit platelet aggregation and rapid transport to a facility capable of percutaneous coronary intervention (PCI) for definitive management, as NSTEMI is still an acute coronary syndrome.
Why the other options are wrong
- A. Transcutaneous pacing is for symptomatic bradycardia, which this patient does not have.
- C. Thrombolytic therapy is generally reserved for STEMI when PCI is not readily available, and has specific contraindications not fully assessed here.
- D. Adenosine is for narrow-complex tachycardias, not for acute coronary syndromes.
NSTEMI/Unstable Angina Management
NSTEMI and Unstable Angina are Acute Coronary Syndromes (ACS) characterized by myocardial ischemia without complete ST elevation, often presenting with atypical symptoms.
- ECG shows ST depression or T wave inversion, not ST elevation.
- Cardiac markers are elevated in NSTEMI but not Unstable Angina.
- Management includes antiplatelets, anticoagulants, and consideration of PCI.
Memory trick: Heart attack warning, act with speed, Aspirin and transport, what they need.
