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 research is published in the March 16, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology. The study found an association even when people were taking statin drugs meant to lower triglycerides and protect against heart attack and stroke.
