Myosteatosis: A Silent Killer

Introduction: The Risks of Myosteatosis

Myosteatosis: A Silent Killer – Research has found that individuals with myosteatosis are at higher risk.

Who are asymptomatic, had a considerably higher risk of death and serious health problems. Surprisingly, this risk can be compared to those brought on by smoking or type 2 diabetes and is unrelated to age or obesity indicators like Body Mass Index (BMI).

Myosteatosis:A silent killer;Body Composition and the Limitations of BMI

BMI is not a reliable indicator of body composition. Patients with comparable BMIs might have a wide range of comorbidities and health risks. Therefore, CT/MRI scans can provide a more detailed assessment of body composition.

Myosteatosis: Fat Accumulation in Muscles

When fat builds up inside the muscles, myosteatosis occurs. Little is known about the health hazards associated with myosteatosis in asymptomatic persons since it is often discovered in patients who are already unwell and receiving medical imaging for other reasons. Myosteatosis evaluation using medical imaging with a CT or MRI continues to be the gold standard.

Investigating the Link: Myosteatosis and Mortality Risk

Researchers examined body composition measurements from abdominal CT images of asymptomatic patients who had received standard colorectal cancer screening in a retrospective analysis using AI technology. The study also looked at other markers such as visceral fat, hepatic steatosis, myopenia (muscle atrophy), and obesity. Its goal was to determine the relationship between myosteatosis and mortality risk. Data on follow-up was gathered for an average of 8.8 years.

Independent Risk Factor: Myosteatosis vs. Other Health Factors

Among the 8,982 participants in the study, researchers found a higher risk of death and serious adverse outcomes associated with myosteatosis. Myosteatosis was present in 55% of the deceased research subjects.

Surprisingly, independent of age or indicators of obesity like BMI, the association between myosteatosis and mortality risk remained strong. It was not enough to say that aging or the buildup of fat in other parts of the body might explain myosteatosis.

Comparable Risks: Myosteatosis and Smoking or Type 2 Diabetes

Myosteatosis presented a mortality risk comparable to that of smoking and type 2 diabetes, surpassing other variables such as visceral obesity and hepatic steatosis in predicting mortality risk.

Overlooked Condition: Raising Awareness in the Medical Community

Despite mounting evidence of myosteatosis’s hazards, the medical profession continues to ignore this illness. To ascertain if myosteatosis is directly connected to an increased risk of mortality or if it is only an indicator of a poor health state, more study is required.

Future Implications: Personalized Medicine and Myosteatosis

The study highlights the potential use of personalized medicine in managing an individual’s health based on various characteristics, including myosteatosis.

Assessment of patient’s genetics, medical history, physical traits, and imaging.

Collaborative Research: University of Wisconsin-Madison’s Study

Under the direction of co-author Perry J. Pickhardt, M.D., participants were recruited for the research and scanned at the University of Wisconsin-Madison. The researchers made use of artificial intelligence (AI) software created by co-author Ronald M. Summers’ group at the National Institutes of Health Clinical Center.


The buildup of fat in muscles, known as myosteatosis, poses a concealed threat with serious health concerns. Regardless of age or the presence of obesity-related indicators, this syndrome raises the risk of serious adverse events and death. Healthcare practitioners should be aware of myosteatosis and create strategies to control it.

A metric obtained from standard medical imaging called myosteatosis has the potential to be a reliable predictor of a person’s mortality risk. To enhance patient outcomes, healthcare providers can take proactive measures.
