Scientists at the University of Copenhagen (Denmark) found that a sense of loneliness increases the risk of complications of cardiovascular disease and premature death in men and women.
The study involved 13,436 patients with ischemic heart disease, arrhythmia, heart failure, or heart valve disease. Volunteers filled out questionnaires that indicated the state of their physical and psychological health, lifestyle, including a tendency to bad habits, as well as living with other people.
Previous studies have shown that loneliness is associated with coronary heart disease and stroke. However, the results of the new work demonstrated that loneliness and social isolation of patients contributed to complications, regardless of the type of cardiovascular diseases that they suffered. This dependence persists with additional factors, including smoking, alcohol consumption, weight, age and educational level.
At the same time, the risk of premature death in men and women increased approximately two-fold. In addition, a sense of loneliness contributed to depression, anxiety and a deterioration in the quality of life.
