How To Avoid Aortic Dissection

Avoiding an aortic dissection—a dangerous tear in the inner layer of the aorta—involves many of the same strategies as preventing an aneurysm, but with extra attention to blood pressure control and genetic risk.

Here’s a detailed breakdown of how to reduce your risk of aortic dissection:

🧠 What Is an Aortic Dissection?

An aortic dissection happens when a tear in the inner wall of the aorta allows blood to flow between layers of the wall, forcing them apart. This can be rapidly fatal if not treated.

✅ How To Prevent It

1. 🩺 Strict Blood Pressure Control

  • This is the #1 prevention strategy.
  • Goal: <120/80 mmHg (sometimes even lower if you’re high-risk).
  • Use medications if needed:
    • Beta-blockers (especially for those with Marfan or other connective tissue disorders)
    • ACE inhibitors or ARBs
  • Monitor at home regularly if you’re at risk.

2. 🚭 Quit Smoking

  • Smoking severely weakens the walls of arteries and increases dissection risk.
  • It’s a top modifiable risk factor—quitting is crucial.

3. 🧬 Understand Your Genetics

If you have or suspect conditions like:

  • Marfan syndrome
  • Loeys-Dietz syndrome
  • Ehlers-Danlos syndrome (vascular type)
  • Bicuspid aortic valve
  • Or a family history of dissection

👉 Get regular imaging (e.g., echocardiograms, MRIs) to monitor your aorta. 👉 Genetic counseling can help assess your risk.

4. 💊 Take Prescribed Medications

  • If you’re already diagnosed with an enlarged aorta or connective tissue disorder, take your meds exactly as prescribed.
  • Beta-blockers and ARBs can reduce aortic wall stress and slow the growth of dilation.

5. 🧘‍♂️ Avoid Sudden Exertion or Heavy Lifting

  • Especially important for high-risk people.
  • Sudden surges in blood pressure from:
    • Straining (lifting weights, constipation)
    • Intense emotional stress
    • High-intensity workouts
      …can trigger a tear in the aortic wall.

6. 🍎 Maintain Overall Heart Health

  • Follow a heart-healthy diet (DASH or Mediterranean)
  • Exercise regularly but gently—avoid extremes
  • Keep cholesterol and diabetes under control

7. 🩻 Get Imaging If You Have Symptoms or Risk

  • If you’re at risk, regular monitoring with CT angiography, MRI, or echocardiograms can help catch an aortic enlargement early before it dissects.

⚠️ Watch for Warning Signs

Seek emergency care if you experience:

  • Sudden, severe chest or upper back pain (often described as “tearing” or “ripping”)
  • Pain that radiates to the neck or jaw
  • Fainting or shortness of breath
  • Weak pulse or different blood pressures in each arm
