Read the first 7 Stroke Prevention & Risk Management flashcards as text
A 68-year-old patient with a recent TIA has a CHADS2 score of 3. Which anticoagulation strategy is most appropriate?
Answer: Anticoagulation with a direct oral anticoagulant or warfarin
A CHADS2 score of 3 indicates high stroke risk in atrial fibrillation, making anticoagulation the preferred stroke prevention strategy.
Which lipid-lowering target is recommended for patients with ischemic stroke or TIA of atherosclerotic origin to reduce recurrent stroke risk?
Answer: LDL <70 mg/dL
High-intensity statin therapy targeting LDL <70 mg/dL is recommended for atherosclerotic ischemic stroke or TIA to reduce recurrence.
A patient with symptomatic ipsilateral carotid stenosis of 75% is medically stable. What is the recommended timeframe for carotid revascularization?
Answer: Within 2 weeks of the index event
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.
Which blood pressure target is recommended for long-term secondary stroke prevention in a non-lacunar ischemic stroke patient?
Answer: <140/90 mmHg or lower
Guidelines recommend achieving BP <140/90 mmHg (and ideally lower) for most ischemic stroke survivors to reduce recurrent event risk.
Patent foramen ovale (PFO) closure is most appropriate in which stroke patient population?
Answer: Younger patients (<60) with cryptogenic stroke and high-risk PFO features
PFO closure is recommended for younger cryptogenic stroke patients with high-risk anatomic features (large shunt, atrial septal aneurysm) after ruling out other etiologies.
A diabetic patient post-stroke has an HbA1c of 9.2%. What is the primary glycemic management goal for stroke prevention?
Answer: Moderate glycemic control targeting HbA1c <7–8% while avoiding hypoglycemia
Moderate glycemic control (HbA1c <7–8%) is recommended for diabetic stroke survivors, balancing cardiovascular benefit against hypoglycemia risk.
Which non-pharmacologic intervention has the strongest evidence for primary stroke prevention in adults with hypertension?
Answer: Salt restriction combined with the DASH diet
The DASH diet combined with sodium restriction consistently lowers blood pressure and is among the most evidence-based lifestyle interventions for primary stroke prevention.
