Condition: Coronary Heart Disease (CHD) · Anxiety Disorders · Sponsor: Shenyang Medical College
The goal of this clinical trial is to test whether real-time fNIRS-BCI neurofeedback targeting the right dorsolateral prefrontal cortex (right DLPFC), using active volitional control during a slow-wave auditory acoustic paradigm, can suppress cardiac sympathetic activity and improve autonomic regulation in right-handed patients with stable coronary heart disease (CHD) and comorbid DSM-5 anxiety. The main questions it aims to answer are: Does real neurofeedback, compared with sham, reduce baseline-corrected heart rate during the auditory stimulation window? Does real neurofeedback, compared with sham, increase HRV spectral power around 0.0167 Hz (1/60 Hz) and produce stronger suppression of right DLPFC activation? Does suppression of right DLPFC activation mediate the effect of group assignment on heart rate? If there is a comparison group: Researchers will compare the real neurofeedback group with the sham (non-contingent) feedback group, which uses identical audio and interface, to determine whether coupling feedback to right DLPFC activity yields autonomic benefits. Participants will: Complete eligibility screening in cardiology and psychiatry and provide informed consent; baseline demographics, medical history, vital signs, and medications are recorded (HAMA/HAMD used for eligibility only). Undergo a 3-day adaptation phase to practice active volitional self-regulation while viewing a real-time energy bar mapped to right DLPFC statistics; adaptation data are not analy…
