The present study investigated whether completion of an exercise-based cardiac rehabilitation (CR) program was associated with improvements in both traditional cardiovascular risk factors and insomnia symptoms, and whether degree of improvement in insomnia symptom severity was associated with degree of improvement in cardiovascular risk.
Participants (N = 80) with cardiovascular disease completed a 12-week outpatient CR program involving supervised moderate-intensity exercise sessions held twice weekly. Insomnia symptom severity, blood pressure, body mass index, psychological distress, and lipid profile were measured at baseline and after completion of the program.
Nearly 40% reported mild to moderate insomnia symptom severity at baseline. There were improvements in insomnia symptom severity, anxious and depressive symptoms, low-density lipoprotein levels, triglycerides, and total cholesterol from baseline to post-program. After statistical adjustment for age, sex, and functional capacity, greater improvement in insomnia symptom severity was associated with greater improvements in total cholesterol and symptoms of anxiety and depression.
Completion of CR may contribute to improved sleep that, in turn, is associated with improvements on some indices of cardiovascular risk. Future research should examine the direction of the association between insomnia and cardiovascular risk, including whether efforts to alleviate insomnia may bolster the cardiovascular benefits of CR.
本研究旨在探讨完成基于运动的心脏康复（CR）计划是否与传统心血管危险因素和失眠症状的改善有关，以及失眠症状严重程度的改善程度是否与心血管风险的改善程度相关。
患有心血管疾病的参与者（N=80）完成了为期 12 周的门诊 CR 计划，包括每周两次的监督性中等强度运动课程。在基线和计划完成后测量失眠症状严重程度、血压、体重指数、心理困扰和血脂谱。
近 40%的人在基线时报告有轻度至中度失眠症状严重程度。失眠症状严重程度、焦虑和抑郁症状、低密度脂蛋白水平、甘油三酯和总胆固醇从基线到计划后均有改善。经过年龄、性别和功能能力的统计调整后，失眠症状严重程度的改善与总胆固醇和焦虑、抑郁症状的改善更相关。
CR 的完成可能有助于改善睡眠，而睡眠的改善又与心血管风险的某些指标的改善有关。未来的研究应探讨失眠与心血管风险之间的关联方向，包括缓解失眠是否可能增强 CR 的心血管益处。
