Fat around heart promotes atherosclerosis, reveals study published in the journal Radiology.
New results from the Multi-Ethnic Study of Atherosclerosis (MESA) show that pericardial fat is more strongly related to coronary artery plaque than either body mass index (BMI) or waist circumference.
When plaque forms in the arteries, it deposits in an irregular manner, causing thickening of the artery wall on one side, but not the other. The ratio of the thick side to the thin side is referred to as plaque eccentricity and is a strong indicator of heart disease.
According to the American Heart Association, heart disease is the leading cause of death in theU.S. U.S.
While previous studies have looked at the relationship of pericardial fat to atherosclerosis in patients with severe coronary disease, this is the first study to determine the association of pericardial fat on coronary artery plaque burden in asymptomatic individuals.
"The individuals in this study had no symptoms and were otherwise healthy," said senior author David A. Bluemke, M.D., Ph.D., director of Radiology and Imaging Sciences at the National Institutes of Health (NIH) Clinical Care. "They did not have significant coronary artery narrowing. Yet, despite this, they had coronary plaque that could be detected by MRI."
