General Medicine · Cardiology: reperfusion in STEMI
Sample itemA 52-year-old man arrives at a district hospital without a catheterisation laboratory, 2 hours after the onset of chest pain, with ST elevation in the anterior leads. He has no contraindication to fibrinolysis. The nearest PCI-capable centre is about 3 hours away by road. What is the best strategy?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Give a fibrinolytic now, then transfer to the PCI centre for angiography
Primary PCI is preferred only when it can be done within about 120 minutes of first medical contact. When this is not achievable, prompt fibrinolysis followed by transfer to a PCI-capable centre (the pharmaco-invasive strategy) is recommended, with rescue PCI if it fails and angiography within 24 hours if it succeeds. ST elevation with typical pain is itself sufficient to act; troponin should not delay treatment.
Option by option
A. Give a fibrinolytic now, then transfer to the PCI centre for angiography (correct)
A pharmaco-invasive approach saves myocardium when PCI delay is too long.
B. Withhold reperfusion and transfer for primary PCI regardless of delay
A transfer taking 3 hours or more would leave the artery occluded for too long.
C. Give a fibrinolytic and discharge him if the pain settles
Even after successful fibrinolysis, patients need transfer for angiography and risk stratification.
D. Give aspirin and heparin only, and wait for the troponin result
STEMI is diagnosed on ECG and symptoms; waiting for troponin wastes myocardium.
