Stroke can have many causes. An atherothrombotic stroke is caused by a clot that forms from plaques that build up within blood vessels in the brain. A new study suggests that people who have this type of stroke who also have higher levels of triglycerides, a type of fat, in their blood may have a higher risk of having another stroke or other cardiovascular problems one year later, compared to people who had a stroke but have lower triglyceride levels. The study found an association even when people were taking statin drugs meant to lower triglycerides and protect against heart attack and stroke.
