Cleveland HeartLab Launches Only Clinical Test for Measuring TMAO, an important measure of Gut Dysfunction Associated with Cardiovascular Disease Risk

CLEVELAND, Feb. 16, 2016 /PRNewswire/ -- Cleveland HeartLab Inc., the premier cardiovascular disease management company, announced it has successfully developed, validated and launched a new clinical test for the assessment of TMAO (trimethylamine-N-oxide), a dietary-derived metabolite that is produced by gut bacteria and is strongly associated with cardiovascular disease. This compound may explain the link between the high incidence of heart disease and diets rich in red meat and dairy products.

Licensed from the Cleveland Clinic, TMAO has received widespread scientific and public attention since its discovery. In 2013, the American Heart Association and the American Stroke Association selected the discovery of the connection between gut flora, TMAO, and cardiovascular disease risk as one of that year's "Top 10 advances in heart disease and stroke science." TMAO has also been featured in the leading medical and scientific publications including The New England Journal of Medicine and Nature, as well as reported by NPR, Time, The New York Times, and most recently in the PBS documentary "In Defense of Food."

Discovered by researchers in Cleveland Clinic's Lerner Research and Heart & Vascular Institutes, Cleveland HeartLab's new blood test measures levels of TMAO, which is a powerful indicator of future risk for heart attack, stroke, and death in patients who may otherwise appear healthy, according to Cleveland Clinic research. TMAO offers physicians insight into whether the gut is contributing to vascular inflammation present in those patients with positive risk markers from Cleveland HeartLab. 

"This is an exciting discovery," said Nina Radford, MD, Director of Clinical Research and a cardiologist at Cooper Clinic. "Prevention is our primary focus at Cooper Clinic and we've known for decades that diets rich in animal and saturated fats are associated with increased risk of heart disease. TMAO testing has the potential to help us connect the dots between diet and cardiovascular disease for each patient. This test may identify additional targets for risk factor modification to reduce a patient's risk of serious cardiovascular disease events."

Additional research recently published in Cell investigates how the negative cardiovascular effects of TMAO can be prevented. The compound DMB (3,3-Dimethyl-1-butanol) was found to inhibit production of TMAO from the gut bacteria of laboratory animals. Many heart-healthy foods are rich in DMB, including cold-pressed olive oil, balsamic vinegars and red wines. This breakthrough may potentially lead to a dietary-based therapy through which individuals eat foods rich in DMB to prevent TMAO production in order to reduce their risk of CVD. Last year, Procter & Gamble announced it is working to develop an over-the-counter product to help people manage their TMAO levels.

"TMAO could be a major missing piece in the puzzle of our understanding of cardiovascular disease," according to Michael F. Roizen, MD, Chief Wellness Officer at the Cleveland Clinic Foundation. "For some patients, diets rich in saturated fats dramatically increase the risk of cardiovascular disease. While in others, the same diet has a marginal impact on risk. With this new information, we can better assess the heart attack risk and overall heart health of each individual patient and help guide them to make the specific lifestyle changes best suited for their unique risk."

"Launching TMAO testing in our world-class clinical lab is another example of Cleveland HeartLab's ability to bring a great clinical discovery from a leading medical institution to the market. Clinicians have come to rely on us for breakthrough innovations such as these and we are pleased that we have been able to translate world-class science into actionable results for patients with heart disease or who are at risk for heart disease or stroke," said Jake Orville, CEO of Cleveland HeartLab Inc.
