Abstract
Aim: The aim of the study was to explore the impact of anxiety and/or depression on prognosis among CAD patients with stent implantation and to find an intervention to improve symptoms of anxiety and depression for this kind of patients. The specific objectives include: 1) to explore the impact of anxiety and depression on MACEs in Chinese CAD patients after stent implantation; (2) to confirm the effectiveness of a six weeks, one-on-one, face-to-face combined with phone-delivered multiform mindfulness-based stress reduction (mMBSR) on the improvement of anxiety, depression, and stress in Chinese CAD patients with stent implantation.
Methods: Part 1: The impact of anxiety and depression on cardiovascular events of patients with coronary artery stent implantation. Patients who were diagnosed CAD for the first time and met the established criteria were recruited from the First and Second Affiliated Hospital of Soochow University, the Affiliated Hospital of Jiangnan University and the Affiliated Hospital of Nantong University between June 2015 and May 2016.
Part -2: The effectiveness of mMBSR on anxiety and depression in CAD patients with coronary artery stent implantation: A randomized controlled trial. 70 patients who met the established criteria were recruited within 1-4 days after coronary stent implantation from the First Affiliated Hospital of Soochow University between 22 June 2016 and 4 January 2017 and were randomized equally to experimental or control group. Patients in experimental group received a six-weeks, one-on-one, face-to-face combined with phone-delivered MBSR intervention, while patients in control group received routine care. The levels of anxiety, depression, stress and mindfulness were compared between the two groups before and after intervention. The mediating role of mindfulness in the effects of MBSR on improvement of anxiety, depression and stress was analyzed.
Results: Part 1: A total of 328 copies of the initial questionnaire were collected. Among those collected, 19 were excluded, and the remaining 309 were considered valid; the effective recovery rate was 94.21 %. 100 patients (32.36%) had anxiety, 80 (25.89%) had depression, and 56 (18.12%) had anxiety combined with depression. Part 2. 5 patients who practiced mindfulness exercise less than 80% of required in the experimental group were treated as withdrawal. 4 patients in the control group refused to cooperate and did not complete the questionnaires at final. We finally analyzed the data of patients who completed the intervention and questionnaires, with 30 in experimental and 31 in control group.
Conclusion : The prevalence rates of anxiety and depression are high in CAD patients with stent implantation. The occurrence of MACEs still poses clinical problems in CAD patients after stent implantation. Depression is an independent predictor of MACEs. The symptom of anxiety combined with depression increases the risk of MACEs significantly. Although anxiety is associated with MACEs, it has no additional value in the case of co-occurring depression.
