Insomnia tied to higher risk of heart disease, 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.
Previous observational studies have found an association between insomnia, which affects up to 30% of the general population, and an increased risk of developing heart disease and stroke. These observational studies were unable to determine whether insomnia is a cause, or if it is just associated with them, explained Susanna Larsson, Ph.D., lead study author and associate professor of cardiovascular and nutritional epidemiology at Karolinska Institutet in Stockholm, Sweden.
