Insomnia tied to higher risk of heart disease and stroke
People suffering from insomnia may have an increased risk of coronary artery disease, heart failure and stroke, according to new research in the American Heart Association's journal Circulation.

In this first-of-its-kind study on insomnia, Susanna Larsson, Ph.D., lead study author at Karolinska Institutet in Stockholm, Sweden and a colleague applied Mendelian randomization, a technique that uses genetic variants known to be connected with a potential risk factor, such as insomnia, to reduce bias in the results. The 1.3 million participants with or without heart disease and stroke were drawn from four major public studies and groups.

Researchers found genetic variants for insomnia were associated with significantly higher odds of coronary artery disease, heart failure and ischemic stroke - particularly large artery stroke, but not atrial fibrillation.

"It's important to identify the underlying reason for insomnia and treat it," Larsson said. "Sleep is a behavior that can be changed by new habits and stress management."
