Answers are grounded in this paper and cite their sources.
Physically healthy, unmedicated patients with MDD, particularly those with comorbid GAD, exhibit reduced heart rate variability, highlighting a potential mechanism for increased cardiovascular risk in this population.
Unmedicated, physically healthy MDD patients with and without comorbid anxiety had reduced HRV. Those with comorbid GAD showed the greatest reductions. Implications for cardiovascular risk reduction strategies in otherwise healthy patients with psychiatric illness are discussed.
