High triglycerides linked to increased likelihood of stroke.
Most stroke-prevention guidelines focus on cholesterol levels, but a recent study suggests it may be levels of a type of fat called triglycerides that more accurately reflect increased risk for brain-damaging strokes. Triglyceride fats may be indicators of the presence of fat particles similar to "bad" low-density lipoproteins (LDL) that build up on the walls of blood vessels. The plaques can break loose and interfere with blood flow in brain blood vessels, causing a stroke that injures or destroys brain tissue. Statin medications lower both LDL ("bad") cholesterol and triglyceride fats, which may explain why they are associated with lower stroke risk. In a three-decade study of almost 14,000 men and women, researchers found that participants with higher non-fasting triglyceride levels were more likely to suffer a stroke. Women whose mean triglyceride levels were 443 mg/dL had four times the risk of a stroke as women whose mean levels were 89 mg/dL, according to a report in the Feb. 21, 2011 Annals of Neurology. Men with the highest triglyceride levels had more than twice the risk of a stroke as those with the lowest levels. Levels of triglycerides considered normal are lower than 150 mg/dL, according to the American Heart Association.
