In recent years, scientists have learned more about how
triglycerides contribute to atherosclerosis, the clogged arteries
that raise the risk of heart attack, stroke, and other

High triglyceride levels are also a component of another heart
disease risk factor — metabolic syndrome, a condition that occurs
in most people with type 2 diabetes and includes high blood

The American Heart Association (AHA) issued a scientific
statement about triglycerides and cardiovascular disease that
sets a new, lower optimal level of triglycerides and recommends
