Here we sought to determine whether anxiety disorders or their symptoms spanning a non-clinical to clinical spectrum are associated with stronger relations with HRV. Although reductions in HRV may provide a link between anxiety and ill health, past studies on anxiety disorders have reported contradictory findings. Reductions in resting-state heart rate variability (HRV) reflect cardiac autonomic dysfunction, which plays a key role in the development of cardiovascular diseases. Anxiety disorders carry a three to four-fold increased risk of cardiovascular disease (CVD) after accounting for gender, substance use, and depression, and a two-fold increased risk for cardiac mortality. These results enhance understanding of the relationship between the cardiac autonomic nervous system and anxiety psychopathology, providing support for dimensional-trait models consistent with the Research Domain Criteria framework.Īnxiety disorders are the most prevalent of the psychiatric disorders, and the most costly. The specific symptom of worry – not the diagnosis of an anxiety disorder – was associated with the most robust reductions in HRV, indicating that HRV may provide a transdiagnostic biomarker of worry. High worriers (Total n = 41 n = 22 diagnosed with an anxiety disorder and n = 19 not meeting criteria for any psychopathology) displayed a robust reduction in resting state HRV relative to low worriers ( p =. Participants who fulfilled DSM-IV criteria for an anxiety disorder displayed diminished HRV, a difference at trend level significance ( p =. Symptom severity measures of worry, anxiety, stress, and depression were also collected from participants, regardless of diagnosis. Resting-state HRV was calculated in participants with clinical anxiety ( n = 25) and healthy controls ( n = 58). Here we investigated whether anxiety disorders or symptoms of anxiety, stress, worry and depression are more strongly associated with resting-state HRV. It is possible that HRV reductions may transcend diagnostic categories, consistent with dimensional-trait models of psychopathology. ( with anxiety disorders display reduced resting-state heart rate variability (HRV), although findings have been contradictory and the role of specific symptoms has been less clear.
