(STUDY FINDS) -- STOCKHOLM, Sweden — Insomnia is an incredibly frustrating, and common, condition all over the world. An estimated 30% of the general population deals with the condition regularly, and for many people difficulty falling asleep tends to run in their family. Now, a study finds an association between genetic predisposition to insomnia and an increased risk of coronary artery disease, stroke, and heart failure.
According to Dr. Susanna Larsson, the study’s lead author and a professor at the Karolinska Institute in Sweden, previous research had already established a connection between insomnia and increased risk of stroke and heart disease. However, this earlier work had failed to determine if insomnia was the cause of these heart problems, or just associated with them.
