Mental Stress Ischemia: Biofeedback Study

Status Completed

Clinical Trial Summary

Clinical Trial Description

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. This is a randomized controlled study. 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.

All participants will undergo myocardial flow/perfusion imaging with positron emission tomography (PET) imaging at rest and after a standardized arithmetic mental stress test. Participants will then undergo repeat testing after 6 weeks. At 12 weeks, participants will also undergo a limited examination without myocardial perfusion imaging. The intervention group will receive biofeedback after enrollment, and the wait-list control group will receive the intervention between week 6 and week 12 study visits (without imaging). ;
