Depressive Symptoms Predict Heart Rate Recovery After Exercise Treadmill Testing in Patients With Coronary Artery Disease: Results From the Psychophysiological Investigations of Myocardial Ischemia Study

Depressive symptoms are associated with cardiovascular autonomic nervous system dysfunction as assessed by HR recovery. This relationship is not merely due to an association of depression severity with beta blocker usage or a failure of depressed patients to achieve an adequate chronotropic response.
