Stress Related Disorders Associated With Increased Risk of Cardiovascular Disease
Stress related disorders include obsessive-compulsive disorder and post-traumatic stress disorder, and are triggered by a significant life event or trauma. According to a new study, stress related disorders may increase the risk of cardiovascular disease by up to 64%.
The researchers identified 136,637 people who had been diagnosed with a stress related disorder between January 1987 and December 2013 to participate in the study. These participants were matched with 171,314 unaffected siblings and 1,366,370 unaffected people from the general population. The participants were followed for 27 years and all cases of cardiovascular disease were recorded.
When the researchers compared rates of cardiovascular disease between the three groups, they found that participants who been diagnosed with a stress related disorder were 64% more likely to develop cardiovascular disease than their siblings. The risk was approximately the same when compared to the general population. In addition, those who were diagnosed with a stress related disorder at a younger age had an increased risk of early onset cardiovascular disease, compared to those diagnosed later in life.
The study was conducted by researchers from Karolinska Institutet, Stockholm, Uppsala University, and Karolinska University Hospital. It waspublished April 10, 2019 in The BMJ.
