Fatty liver disease may pose a greater threat to cardiovascular health than previously recognized, according to new research suggesting the condition is associated with a significantly increased risk of heart attacks and other major cardiac events.
The findings add to growing evidence that fatty liver disease affects more than just the liver, highlighting its potential role in the development of serious heart-related complications.
Researchers Identify Strong Heart Disease Connection
In the study, researchers examined health data from more than 3,600 adults across the United States who were undergoing evaluation for stable chest pain and had no previous history of cardiovascular disease.
Using advanced imaging technology, investigators assessed both liver health and coronary artery conditions during the same scan. The results showed that approximately one-quarter of participants had fatty liver disease.
Individuals with the condition were more likely to have diabetes and showed higher levels of plaque buildup inside their coronary arteries compared with those who did not have fatty liver disease. Researchers also found a greater presence of unstable plaque, which is considered more likely to rupture and trigger a heart attack.
Increased Risk of Major Cardiovascular Events
Participants were monitored for two years following their initial assessment. During that period, people with fatty liver disease experienced higher rates of major cardiovascular events, including heart attacks, hospitalization for severe chest pain, and cardiovascular-related deaths.
Even after accounting for traditional risk factors such as obesity, diabetes, and the extent of arterial blockage, fatty liver disease remained independently associated with a substantially higher likelihood of serious heart complications.
The findings suggest that the condition may contribute directly to cardiovascular risk rather than simply occurring alongside other health problems.
Why Fatty Liver Disease Matters
Fatty liver disease develops when excess fat accumulates in the liver, often as a result of obesity, insulin resistance, poor dietary habits, or metabolic disorders. While the condition may not cause noticeable symptoms in its early stages, it can progress to liver inflammation, scarring, and other complications if left untreated.
Researchers believe the disease may also promote chronic inflammation and metabolic changes that negatively affect blood vessels and heart health.
Early Detection Could Improve Outcomes
The study highlights the potential value of screening individuals with fatty liver disease for cardiovascular risk factors. Advanced imaging techniques may help healthcare providers identify patients who are at increased risk and require closer monitoring or earlier intervention.
Experts say recognizing the connection between liver health and heart health could improve prevention strategies and reduce the likelihood of future cardiac events.
Steps to Lower Risk
Although the findings are concerning, fatty liver disease is often reversible, particularly when identified early. Lifestyle measures that can help improve liver health and reduce cardiovascular risk include:
- Maintaining a healthy weight
- Engaging in regular physical activity
- Limiting processed foods and added sugars
- Following a balanced, nutrient-rich diet
- Managing blood pressure, cholesterol, and blood sugar levels
- Avoiding excessive alcohol consumption
Health professionals emphasize that improving liver health may also provide important benefits for the heart, making early diagnosis and treatment a key part of long-term disease prevention.
