Stroke Recurrence Risk: Modifiable Factors and Prevention Strategies

After a first stroke or TIA, the 1-year recurrence risk is 5–15%; 5-year risk is 25–35%. Up to 80% of recurrent strokes are preventable.

Major Modifiable Risk Factors

• Hypertension: Target <130/80 mmHg (per AHA/ASA). Most impactful single factor.
• Atrial Fibrillation: Anticoagulation (DOAC preferred) reduces stroke by 64%.
• Dyslipidemia: High-intensity statin (atorvastatin 40–80, rosuvastatin 20–40) for all ischemic stroke/TIA.
• Diabetes: HbA1c <7%; SGLT2i/GLP-1 RA for cardio-renal benefit.
• Smoking: Cessation → risk drops to never-smoker level by 5 years.
• Physical Inactivity: 150 min/week moderate aerobic exercise.
• Diet: Mediterranean/DASH—high fiber, fish, olive oil; low sodium, saturated fat.
• Alcohol: ≤1 drink/day (women), ≤2 (men).
• Obesity: BMI <25; monitor waist circumference.
• Sleep Apnea: Screen (STOP-BANG); treat with CPAP.

Secondary Prevention Medications

• Antiplatelet: Aspirin 81 mg + clopidogrel 75 mg × 21–30 days (minor stroke/TIA), then monotherapy.
• Anticoagulant for cardioembolic source.
• Statin + BP medications as above.

Action Plan

1. Know your ABCs: A1c, BP, Cholesterol.
2. Take medications exactly as prescribed.
3. Act FAST (Face, Arm, Speech, Time) for any new symptoms.
4. Regular follow-up with neurologist/stroke clinic.

Secondary prevention is a lifelong commitment—but the most effective investment in future independence.
