BACKGROUND & OBJECTIVE: Evidences suggest that relaxation therapy may improve psychological outcomes in heart patients. We evaluated the effect of progressive muscular relaxation (PMR) training in decreasing anxiety and improving quality of life among anxious patients after coronary artery bypass graft surgery (CABG).
This study was an open uncontrolled trial. The sample included 110 anxious patients referred to the cardiac rehabilitation clinic of Tehran Heart Center, Tehran, Iran, during six weeks after coronary artery bypass graft (CABG). Patients were allocated to receive both exercise training and lifestyle education plus relaxation therapy (relaxation group; n=55) or only exercise training beside lifestyle education (control group or the recipient of usual care group; n=55). Duration of the relaxation therapy was 6 wk and in the case of usual care was 8 wk. Both the groups were followed up one month after completion of intervention. Anxiety and quality of life in the two treatment groups were compared.
There were no significant differences in overall QOL, state anxiety and trait anxiety scores between the two groups before intervention. Significant reductions in state anxiety (P<0.01) and trait anxiety (P<0.01) levels were observed in relaxation group after intervention compared to control group. Women had high state anxiety and a low quality of life than men in the two groups before intervention. After intervention, there was no difference between men and women in the relaxation group.
INTERPRETATION & CONCLUSION: Our findings show that progressive muscular relaxation training may be an effective therapy for improving psychological health and quality of life in anxious heart patients.
有证据表明，放松疗法可能改善心脏病患者的心理状况。我们评估了渐进性肌肉松弛（PMR）训练对冠状动脉旁路移植术（CABG）后焦虑患者减轻焦虑和改善生活质量的效果。
本研究为开放性非对照试验。样本包括在伊朗德黑兰心脏中心心脏康复门诊就诊的110例冠状动脉旁路移植术（CABG）后六周内的焦虑患者。患者被分配接受运动训练、生活方式教育加放松疗法（放松组；n = 55）或仅接受运动训练和生活方式教育（对照组或常规护理组；n = 55）。放松疗法持续6周，常规护理持续8周。两组在干预完成后1个月进行随访。比较两个治疗组的焦虑和生活质量。
干预前两组的总体生活质量、状态焦虑和特质焦虑评分无显著差异。与对照组相比，干预后放松组的状态焦虑（P < 0.01）和特质焦虑（P < 0.01）水平显著降低。干预前两组中女性的状态焦虑高于男性，生活质量低于男性。干预后，放松组中男性和女性之间无差异。
我们的研究结果表明，渐进性肌肉松弛训练可能是改善焦虑心脏病患者心理健康和生活质量的有效疗法。
