Care intervention
AMI, MUSCLE RELAXATION
After randomization, the interventions were carried out by the trained nurses on both CC and CBSM groups for 12 weeks in a team form (8–10 patients per team). Patients assigned to teams based on the order of discharge time and group information. Each intervention was lasted 120 min, and was conducted on the morning of the first Saturday of each week by trained nurses. Notably, the day before each intervention, trained nurses at their respective centers would inform the time and place of the interventions by sending short message service (SMS) texts and emails to remind patients. If patients were initially unresponsive, the trained nurses would subsequently remind them by telephone. In addition, there was no uniform location for the intervention; the patients participated in the intervention at their corresponding centers.For the CC group, the intervention contained a 60-min presentation centered on education related to basic knowledge of AMI, postoperative care, rehabilitation, diet, and physical exercise. Following that, a 30-min question-and-answer session and another 30-min free time were conducted.For the CBSM group, after a 60-min presentation with the same content as the CC group, a specific intervention including a 30-min CBSM skills-teach session and another 30-min CBSM-based relaxation training session was followed. In brief, the 30-min CBSM skills-teach session mainly included the following aspects: (1) stress identification and cognitive reconstruction, which was developed by guiding and encouraging patients to talk about their current problems and stresses; (2) emotion management and confidence building, which was developed by guiding patients to express their emotional changes and the reasons. Besides, the 30-min CBSM-based relaxation training session included deep breathing, meditation, and muscle relaxation.
