"Triglycerides traditionally have been viewed as second-class citizens," said Dr. Michael Miller, director of preventive cardiology at the University of Maryland Medical Center and lead author of the study report, which appears in the Feb. 12 issue of the Journal of the American College of Cardiology. "LDL cholesterol has always taken center stage. We know that LDL is intimately involved in bringing cholesterol to scavenger cells, which deposit them to form plaques in the arteries. This study shows that triglycerides in and of themselves are also to blame."
When triglyceride levels rise too high, however, they may increase the risk of heart disease.
