Deadly Trio: High Blood Pressure, Diabetes, and Low HDL Cholesterol Identified as Key Killers in Fatty Liver Disease
A groundbreaking study from Keck Medicine of USC reveals that high blood pressure, diabetes, and low HDL cholesterol are the most lethal cardiometabolic risk factors for patients with metabolic dysfunction-associated steatotic liver disease (MASLD). Surprisingly, high blood pressure poses a greater mortality risk than diabetes, challenging conventional medical understanding. The research, published in Clinical Gastroenterology and Hepatology, also shows that obesity and accumulating risk factors significantly worsen survival outcomes for the over one-third of global population affected by MASLD.
Metabolic dysfunction-associated steatotic liver disease (MASLD) represents one of the most significant public health challenges of our time, affecting more than a third of the global population. This common chronic liver condition, characterized by fat accumulation in the liver, has now been linked to specific cardiometabolic risk factors that dramatically increase mortality risk according to recent research from Keck Medicine of USC.

The Deadly Trio of Risk Factors
The comprehensive study published in Clinical Gastroenterology and Hepatology identified three primary cardiometabolic risk factors that carry the greatest mortality risk for MASLD patients. High blood pressure emerged as the most dangerous, increasing death risk by 40%, followed by pre-diabetes or Type 2 diabetes at 25%, and low HDL cholesterol at 15%. These findings remained consistent regardless of patients' gender, race, or ethnicity, highlighting their universal significance.
What makes these findings particularly noteworthy is the surprising revelation that high blood pressure poses a greater threat than diabetes, contrary to previous medical assumptions. As noted by Dr. Matthew Dukewich, the study's lead author, this discovery challenges conventional thinking about which health problems require the most urgent attention in MASLD patients.

Obesity and Cumulative Risk Factors
The research also shed light on the significant role of obesity in MASLD mortality. As the most common cardiometabolic risk factor associated with MASLD, obesity demonstrated a clear dose-response relationship with mortality risk. The study found that higher body mass index (BMI) measurements correlated directly with increased death risk, emphasizing the importance of weight management in MASLD treatment.
Perhaps most alarming is the compounding effect of multiple risk factors. The study revealed that each additional cardiometabolic risk factor present in MASLD patients increased mortality risk by 15%. This cumulative effect underscores the importance of comprehensive risk factor management rather than focusing on individual conditions in isolation.
Research Methodology and Implications
The groundbreaking findings emerged from analysis of data from the National Health and Nutrition Examination Survey (NHANES), which collected health information from 1988-2018. From over 134,515 participants aged 20 years or older, researchers identified approximately 21,000 patients meeting MASLD criteria and tracked all-cause mortality rates by individual cardiometabolic risk factors.
According to Dr. Norah A. Terrault, senior author of the study, these insights provide crucial guidance for healthcare providers. Understanding which aspects of MASLD contribute most significantly to poor outcomes enables more targeted and effective patient care strategies. The findings suggest that blood pressure management may deserve greater emphasis in MASLD treatment protocols than previously recognized.

Future Research Directions
The study authors indicate plans for further investigation into additional factors that may influence MASLD outcomes. Future research will examine genetic backgrounds, dietary habits, and alcohol use in relation to MASLD progression and mortality. As Dr. Terrault explains, deeper understanding of disease drivers will help identify patients most in need of interventions and optimize resource allocation for improved outcomes.
This research represents a significant step forward in understanding MASLD mortality risks and provides practical guidance for healthcare providers managing this increasingly common condition. The findings emphasize the need for comprehensive risk factor assessment and management in MASLD patients, with particular attention to blood pressure control, diabetes management, and cholesterol optimization.
