ASC Stroke Prevention & Risk Management 2

Question 1

A 68-year-old patient with a recent TIA has a CHADS2 score of 3. Which anticoagulation strategy is most appropriate?

Accepted Answer

Anticoagulation with a direct oral anticoagulant or warfarin

Answer

A CHADS2 score of 3 indicates high stroke risk in atrial fibrillation, making anticoagulation the preferred stroke prevention strategy.

Question 2

Which lipid-lowering target is recommended for patients with ischemic stroke or TIA of atherosclerotic origin to reduce recurrent stroke risk?

Accepted Answer

LDL <70 mg/dL

Answer

High-intensity statin therapy targeting LDL <70 mg/dL is recommended for atherosclerotic ischemic stroke or TIA to reduce recurrence.

Question 3

A patient with symptomatic ipsilateral carotid stenosis of 75% is medically stable. What is the recommended timeframe for carotid revascularization?

Accepted Answer

Within 2 weeks of the index event

Answer

Early carotid revascularization within 2 weeks of a TIA or minor stroke provides the greatest reduction in recurrent stroke risk for high-grade symptomatic stenosis.

Question 4

Which blood pressure target is recommended for long-term secondary stroke prevention in a non-lacunar ischemic stroke patient?

Accepted Answer

<140/90 mmHg or lower

Answer

Guidelines recommend achieving BP <140/90 mmHg (and ideally lower) for most ischemic stroke survivors to reduce recurrent event risk.

Question 5

Patent foramen ovale (PFO) closure is most appropriate in which stroke patient population?

Accepted Answer

Younger patients (<60) with cryptogenic stroke and high-risk PFO features

Answer

PFO closure is recommended for younger cryptogenic stroke patients with high-risk anatomic features (large shunt, atrial septal aneurysm) after ruling out other etiologies.
