Closed-Loop Neurofeedback Targeting the Left Dorsolateral Prefrontal Cortex for Cardiac Autonomic Modulation in Coronary Artery Disease With Anxiety

The goal of this clinical trial is to test whether closed-loop fNIRS-BCI neurofeedback(NF) targeting the left dorsolateral prefrontal cortex(DLPFC) can reduce cardiac autonomic arousal, indexed by baseline-corrected heart rate(HR) under cold-induced pain stress, in adults with stable coronary heart disease(CHD) and comorbid anxiety. The main questions it aims to answer are: Does real left DLPFC neurofeedback, compared with sham neurofeedback, lead to a greater reduction in baseline-corrected HR during the cold-induced pain stimulation window? Does real neurofeedback produce stronger volitional upregulation of left DLPFC activation and higher inter-hemispheric synchronisation between left and right DLPFC than sham neurofeedback? Are changes in baseline-corrected HR statistically associated with, and partly mediated by, changes in left DLPFC activation or DLPFC inter-hemispheric synchronisation? What adverse events(AEs) occur during adaptive training and the formal experimental session, and do AE rates differ between the two groups? Researchers will compare a real neurofeedback group with a sham neurofeedback group to determine whether targeting the left DLPFC via closed-loop fNIRS-BCI yields superior modulation of cardiac autonomic responses and prefrontal activation patterns in CHD patients with anxiety. Participants will: undergo cardiac and psychiatric screening to confirm stable CHD, DSM-5 anxiety disorder, and other eligibility criteria; attend three adaptive tra…
