Rest Up: Insomnia Linked to Future Heart Failure

theheart.org

Trondheim, Norway — Insomnia symptoms in middle age are strongly associated with the subsequent development of heart failure, a large Norwegian cohort study has found. The analysis, which considered over 54,000 men and women, linked insomnia symptoms and heart failure, even in subjects who had never experienced a coronary event.

Speaking with heartwire, (Dr. Lars E.) Laugsand stressed that the findings do not have immediate implications for physicians, beyond the fact that sleep is important to good health generally.

“That would be the ultimate goal, to do a randomized controlled trial This study is an observational study and saying anything too firm about causality is difficult,” he cautioned. “But from the studies done in insomnia and other sleep problems, we know that sleep problems affect the physiology of the heart.”
