Decoding the genetic roots of stroke and heart attack

In a new study published in the European Heart Journal, researchers at Karolinska Institutet show that genetic traits influence the cellular composition of atherosclerotic plaques, which over time will affect the risk of such lesions to cause a stroke or heart attack. The new knowledge can be used to improve the risk assessment and treatment of patients with atherosclerosis in the future.
