ECC Risk Assessment & Management 3

Question 1

A patient on warfarin presents with NSTEMI. Which bleeding risk score is most commonly applied in this setting before antithrombotic therapy?

Accepted Answer

CRUSADE score

Answer

The CRUSADE score was developed specifically to estimate in-hospital major bleeding risk in NSTEMI patients receiving antithrombotic therapy.

Question 2

Which ECG finding in the context of chest pain represents the highest immediate risk for adverse outcomes?

Accepted Answer

New left bundle branch block (LBBB)

Answer

New LBBB in the setting of chest pain is treated as a STEMI equivalent because it obscures ischemic changes and indicates large territory at risk.

Question 3

In the Wellens syndrome pattern on ECG, what does the characteristic T-wave morphology indicate about risk?

Accepted Answer

High risk; critical LAD stenosis with recent near-occlusion

Answer

Wellens pattern (biphasic or deeply inverted T-waves in V2-V3 during pain-free period) signals critical proximal LAD stenosis at high risk for massive MI.

Question 4

Which patient characteristic MOST significantly increases the risk of adverse outcomes during cardiac arrest resuscitation?

Accepted Answer

Non-shockable initial rhythm (PEA or asystole)

Answer

Non-shockable rhythms (PEA/asystole) have far lower survival rates than shockable rhythms (VF/pVT) because they lack the depolarization amenable to defibrillation.

Question 5

A post-ROSC patient has a MAP of 55 mmHg and SpO2 of 91%. Which post-cardiac arrest risk factor is being poorly managed?

Accepted Answer

Hypotension and hypoxia

Answer

Post-ROSC hypotension (MAP <65) and hypoxia (SpO2 <94%) are both independently associated with worse neurological outcomes and must be corrected urgently.
