Key result
High-level depressive symptoms did not alter cardiovascular reactivity to mental stress compared to low-level symptoms in MDD, while high-frequency HRV predicted heart rate reactivity (β=-.33, p=.002).

Does depression severity affect cardiovascular reactivity to mental stress in patients with major depressive disorder?
In patients with major depressive disorder, cardiovascular reactivity to mental stress appears to be driven by baseline autonomic regulation rather than the severity of depressive symptoms.
Wang et al. (2015) conducted a cross-sectional in Major depressive disorder (n=88). High-level depressive symptoms vs. Low-level depressive symptoms was evaluated on Cardiovascular reactivity to mental stress. High-level depressive symptoms did not alter cardiovascular reactivity to mental stress compared to low-level symptoms in MDD, while high-frequency HRV predicted heart rate reactivity (β=-.33, p=.002).
