Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is to demonstrate whether the combination of chronic remote ischemic conditioning and mindfulness therapy can reduce cardiovascular adverse events in patients with incomplete revascularization of coronary artery disease.

Allocation Method

RANDOMIZED

Intervention Model

FACTORIAL

This study adopts a 2×2 factorial randomized controlled trial design to evaluate the independent and combined effects of chronic remote ischemic preconditioning (CRIC) and mindfulness therapy (MFT) on anxiety and sleep quality in patients with coronary heart disease. Participants will be randomly assigned to one of four groups: (1) CRIC plus MFT, (2) CRIC only, (3) MFT only, or (4) neither intervention (control). The design allows the assessment of the main effects of RIPC and MBT, as well as the potential interaction effect between the two interventions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CRIC+MFT

CIRC: Using a semi-automated machine, the pressure is increased according to the patient's own blood pressure level (20-40mmHg) when the cuff is pressed, and the pressure is compressed for 6 minutes per cycle, and the rest is 4 minutes per cycle.

MFT: Participants receive guided mindfulness audio sessions twice daily for \~30 minutes each throughout the perioperative period. Content includes standardized mindfulness practices (e.g., focused attention, body awareness, nonjudgmental observation) designed to reduce anxiety and improve sleep quality.

Group Type EXPERIMENTAL

chronic remote ischemic conditioning

Intervention Type DEVICE

Using a semi-automated machine, the pressure is increased according to the patient's own blood pressure level (20-40mmHg) when the cuff is pressed, and the pressure is squeezed for 6 minutes per cycle and the rest is 4 minutes, for a total of 4 cycles per cycle.

Mindfulness Therapy

Intervention Type BEHAVIORAL

Participants receive guided mindfulness audio sessions twice daily for \~30 minutes each throughout the perioperative period. Content includes standardized mindfulness practices (e.g., focused attention, body awareness, nonjudgmental observation) designed to reduce anxiety and improve sleep quality.

Control (neither CRIC nor MFT).

Sham CRIC: The pressure was 60mmHg when the cuff was pressurized, and the other modes were the same as in the CIRC group.

Sham MFT: Health Education + Relaxation (HER): A time- and attention-matched audio program (twice daily, 30 minutes) delivering perioperative recovery and sleep-hygiene education with passive relaxation (music or simple muscle loosening), excluding mindfulness-specific techniques (no present-moment/nonjudgmental awareness training, no breath-focused meditation, no open monitoring).

Group Type SHAM_COMPARATOR

Intervention Type OTHER
