Participants who had a heart attack, stroke or died during the study period had higher average TMAO levels than those who didn't experience a cardiovascular event. People with high TMAO levels and no cardiovascular risk factors were 1.8 times more likely to experience a cardiovascular event than those with low levels. "This is going to be a landmark observation," said Dr. Scott Wright, a cardiologist at Mayo Clinic in Rochester, Minn., who was not involved in the study. If the findings are confirmed by future studies, it may result in a shift in dietary recommendations away from foods that may cause gut bacteria to produce TMAO.
