Statins & Stroke

Patient Education: Understanding Statins and Their Role in Preventing Secondary Strokes

What Are Statins?

Statins are a group of medications that lower cholesterol levels in the blood. By reducing “bad” LDL cholesterol, they help protect blood vessels from damage, reducing the risk of blockages that can lead to heart attacks or strokes. Commonly prescribed statins include atorvastatin, simvastatin, and rosuvastatin.

Statins in Stroke Prevention

For patients who have already experienced a stroke or transient ischemic attack (TIA), statins play a critical role in reducing the risk of another stroke. This is known as secondary stroke prevention.

Statins help by:

1. Lowering LDL Cholesterol: High LDL cholesterol contributes to plaque buildup in blood vessels, increasing stroke risk. Statins reduce this.

2. Stabilizing Plaques: Statins prevent plaques from rupturing, a major cause of strokes.

3. Reducing Inflammation: Chronic inflammation damages blood vessels, and statins’ anti-inflammatory effects protect against this.

Common Myths and Misconceptions About Statins

1. “Statins Cause Severe Muscle Problems”

• Fact: While mild muscle aches are a possible side effect, severe muscle damage (rhabdomyolysis) is extremely rare, occurring in less than 0.1% of users. Most patients tolerate statins well. If you experience muscle pain, your doctor can adjust your dose or switch to a different statin.

2. “Statins Lead to Diabetes”

• Fact: Statins can slightly increase blood sugar levels, but the risk of developing diabetes is very low and typically affects those already at high risk. The cardiovascular benefits of statins far outweigh this small risk, especially in preventing life-threatening events like strokes.

3. “I Don’t Need Statins if I Eat Healthy and Exercise”

• Fact: While a healthy lifestyle is crucial, it may not fully address high cholesterol or stroke risk. Statins work alongside lifestyle changes to provide maximum protection.

4. “Statins Harm the Liver”

• Fact: Serious liver issues from statins are extremely rare. Routine blood tests can monitor liver health, ensuring safety.

Benefits of Taking Statins

• Reduce the risk of another stroke by up to 25%.

• Lower cholesterol and stabilize blood vessels.

• Protect against cardiovascular complications.

What to Expect When Taking Statins

• Take statins as prescribed by your doctor.

• Regular follow-up appointments will monitor your cholesterol levels and overall health.

• Report any side effects promptly; adjustments can often resolve concerns.

Your Role in Preventing Strokes

Statins are a powerful tool, but they work best when combined with:

• A balanced diet low in saturated fats.

• Regular exercise, such as walking or swimming.

• Quitting smoking and limiting alcohol intake.
