Gene found to push back heart life by 10 years.

Bristol: Scientists have discovered a gene that pushes the heart back by 10 years.




Heart disease is the leading cause of death globally, with over 17 million deaths reported each year. While lifestyle factors such as diet and exercise play a significant role in the development of heart disease, genetics also play a crucial role. In a recent study, researchers discovered a gene that appears to protect individuals from heart disease, potentially extending their heart lifespan by up to 10 years. In this blog post, we will explore the findings of this study and how it could impact heart disease prevention and treatment.


What is the gene that protects against heart disease?

The study, published in the journal Nature Communications, identified a gene called PNPLA3 that appears to protect individuals from heart disease. The gene is involved in the metabolism of fats in the liver and has previously been linked to liver disease and type 2 diabetes.

However, this study is the first to link PNPLA3 to heart disease. The researchers found that individuals with a specific variant of the gene had a significantly lower risk of developing heart disease, potentially extending their heart lifespan by up to 10 years.


How was the study conducted?

The study involved a large-scale analysis of genetic data from over 500,000 individuals of European descent. The researchers used a technique called Mendelian randomization, which uses genetic variants as proxies for potential causal factors, to assess the relationship between PNPLA3 and heart disease.

The researchers found that individuals with the protective variant of the PNPLA3 gene had a lower risk of heart disease and a longer heart lifespan compared to those without the variant. The effect of the gene was independent of other known risk factors for heart disease, such as high blood pressure and high cholesterol levels.


What does this mean for heart disease prevention and treatment?

The discovery of this gene has significant implications for heart disease prevention and treatment. By identifying individuals with the protective variant of PNPLA3, healthcare professionals could potentially screen for those at lower risk of heart disease and provide targeted prevention strategies.

Additionally, the researchers suggest that the PNPLA3 gene could be a potential therapeutic target for heart disease treatment. By developing drugs that mimic the effects of the gene, it may be possible to reduce the risk of heart disease and extend the heart's lifespan.


What other factors contribute to heart disease risk?

While genetics play a significant role in heart disease risk, lifestyle factors also play a crucial role. Diet, exercise, smoking, and stress all contribute to the development of heart disease.

A diet high in saturated and trans fats, salt, and sugar can increase blood pressure and cholesterol levels, leading to heart disease. Regular exercise can improve heart health by reducing blood pressure and cholesterol levels, and reducing the risk of obesity and diabetes.

Smoking is a significant risk factor for heart disease, as it damages the lining of the blood vessels, leading to the buildup of plaque and increasing the risk of heart attack and stroke. Stress also contributes to heart disease risk by increasing blood pressure and cholesterol levels.


How can you reduce your risk of heart disease?

Reducing your risk of heart disease involves making lifestyle changes that promote heart health. Here are some tips to help reduce your risk of heart disease:

  • Maintain a healthy diet: Eat a diet high in fruits, vegetables, whole grains, and lean proteins, and low in saturated and trans fats, salt, and sugar.
  • Exercise regularly: Aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week.
  • Don't smoke: If you smoke, quit. If you don't smoke, don't start.
  • Manage stress: Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.
  • Maintain a healthy weight: Aim for a body mass index (BMI) between 18.5 and 24.9.
  • Monitor your blood pressure and cholesterol levels: High blood pressure and high cholesterol levels are significant risk factors for heart disease. Regularly monitoring these levels and taking appropriate action to lower them can reduce your risk of heart disease.
  • Limit alcohol intake: Excessive alcohol consumption can increase blood pressure and cholesterol levels, leading to heart disease. Limiting alcohol intake can help reduce your risk of heart disease.
  • Get enough sleep: Poor sleep quality and duration can increase the risk of high blood pressure, obesity, and diabetes, all of which are risk factors for heart disease. Aim for 7-8 hours of sleep per night.
  • Manage underlying health conditions: If you have underlying health conditions such as diabetes or high blood pressure, work with your healthcare professional to manage them effectively.
  • Get regular check-ups: Regular check-ups with your healthcare professional can help detect and treat any underlying health conditions and monitor your heart health.


In conclusion, the discovery of the PNPLA3 gene has significant implications for heart disease prevention and treatment. By identifying individuals with the protective variant of the gene, targeted prevention strategies can be provided, and potential therapeutic targets can be explored. However, genetics is only one factor that contributes to heart disease risk, and lifestyle factors such as diet, exercise, smoking, and stress also play a crucial role. By making lifestyle changes that promote heart health, individuals can reduce their risk of heart disease and live longer, healthier lives.
