Can a Healthy Lifestyle Protect Your Heart Valve?
Share
Most of us know that a healthy lifestyle can help prevent heart attacks and strokes. But did you know it may also protect your heart valves—specifically, your aortic valve, one of the main valves that controls blood flow from your heart?
A new large-scale study shows that maintaining good cardiovascular health—measured by something called Life’s Essential 8—can significantly lower your risk of aortic valve calcification (AVC). Let’s break down what this means and why it matters.
What Is Aortic Valve Calcification (AVC)?
AVC is a condition where calcium builds up on the aortic valve, which can make the valve stiff and narrow. This limits how much blood can flow from the heart to the rest of the body. Over time, AVC can lead to serious problems like:
- Aortic stenosis (severe valve narrowing)
- Heart failure
- Chest pain or fainting
- Even sudden death in advanced cases
AVC is more common as people age, but lifestyle plays a big role too.
What Is Life’s Essential 8?
Life’s Essential 8 (LE8) is a tool developed by the American Heart Association to measure heart health. It includes 8 key areas:
- Diet
- Physical activity
- Nicotine exposure (smoking)
- Sleep
- Body weight
- Blood lipids (cholesterol)
- Blood glucose (sugar)
- Blood pressure
Each of these is scored from 0 to 100, and the average of all 8 gives your overall LE8 score. A higher score means better heart health.
What Did the Study Find?
Researchers followed over 30,000 adults and checked their LE8 scores and ultrasound results for AVC. They found that:
- People with high LE8 scores were 63% less likely to have AVC compared to those with low scores.
- Even moderate improvements in LE8 scores reduced AVC risk by 34%.
- For every step up in the LE8 score, the risk of AVC dropped steadily—showing a clear dose-response effect.
This means that every small lifestyle improvement can help reduce the risk of this serious heart valve problem.
Which Lifestyle Changes Made the Biggest Difference?
Not all parts of the LE8 score had the same impact. The most powerful protective factors were:
- Controlling blood pressure (18% risk reduction)
- Managing blood lipids (17%)
- Keeping a healthy weight (13%)
- Lowering blood sugar (11%)
- Exercising regularly (9%)
- Eating a healthy diet (6%)
Interestingly, sleep and smoking did not show a strong link to AVC in this study. This may be due to limitations in how those habits were measured.
Why Is This Important?
AVC is becoming more common around the world, especially as populations get older. In China alone, AVC cases have increased nearly 11 times in the last 30 years. Yet, there are very few treatments to prevent it. This study shows that lifestyle changes could be a powerful way to protect your heart valves—before problems even start.
The good news? You don’t need to be perfect. Just improving a few key areas—like lowering your blood pressure, eating better, or walking more—can make a real difference.
What You Can Do Today
Want to boost your LE8 score and protect your heart? Here are some practical tips:
1. Know Your Numbers
Check your blood pressure, cholesterol, and blood sugar regularly. Knowing your numbers is the first step toward managing them.
2. Move Your Body
Aim for at least 150 minutes of moderate activity (like walking) or 75 minutes of intense activity (like running) per week.
3. Eat Smart
Choose whole foods—fruits, vegetables, whole grains, lean proteins—and reduce salt, sugar, and high-fat processed foods.
4. Maintain a Healthy Weight
Even a small weight loss (5–10% of your body weight) can help lower blood pressure and improve cholesterol.
5. Quit Smoking and Limit Alcohol
These habits can damage your blood vessels and make heart problems worse. Seek help if you need support to quit.
Final Thoughts
This large study shows that living a heart-healthy lifestyle—as measured by the Life’s Essential 8—can do more than protect you from heart attacks. It may also reduce your risk of aortic valve calcification, a major cause of valve disease.
No matter your age, it’s never too late to start making small changes. Your heart valves—and your future self—will thank you.
