Summary

The purpose of this study is to evaluate the blood flow to the heart during stress and assess changes in blood flow after psychological treatment in participants with coronary artery disease. The aims of the study are to assess the effects of heart rate variability (HRV) biofeedback (versus usual care) on global and regional myocardial blood flow (MBF), peripheral vascular function, and autonomic changes during mental stress.

Interventions

BEHAVIORAL

Heart Rate Variability (HRV) Biofeedback (BF)

Heart Rate Variability (HRV) biofeedback involves deep breathing, mindfulness (focusing on one's emotions and thoughts) and cognitive therapy (identifying and changing unhelpful or inaccurate thinking and distressing emotional responses). It is a 6-week training with one hour sessions with a certified biofeedback coach once per week. A handheld personal stress reliever device will be provided to the patients to practice at home for 20 minutes a day.

OTHER

Mental Stress Protocol

Mental stress will consist of a 3-min math serial subtraction paradigm.The participants will be asked to serially subtract 7 from number specified by the researcher. For participants who have difficulty with this task, easier serial subtraction will be provided for. Throughout the task, to increase stressfulness and titrate difficulty, the participant will be prompted for faster performance and the starting number from which they were subtracting will be periodically changed. Finally, to add an evaluation component, participants will be given negative feedback during the test.
