Abstract

Purpose: Poor sleep quality is harmful for everyone and potentially even more harmful for older adults with atrial fibrillation-associated stroke (AFAS). This study aims to explore the effects of eight-section brocade (ESB) on sleep quality, memory, and cardiopulmonary function in the older adults with AFAS.Methods: Older adults with AFAS and sleep disorders were recruited and divided into the ESB (EG, n = 85) and control groups (CG, general exercise, n = 85). EG patients received 60 min ESB exercises 5 times a week for 12 weeks; CG patients received normal exercise. Pittsburgh sleep quality index (PSQI) scores (poor sleepers ≥8 and normal sleepers < 8), memory for word pairs (poor memory ≤ 7 and normal memory > 7), left ventricular posterior wall (LVPW) thickness, and maximum ventilation (MV, to evaluate cardiopulmonary function) values were measured. The correlation between sleep and memory quality was analyzed using PSQI scores and word pairs via the Pearson correlation coefficients test. Adjusted Cox models were used to explore an interaction between PSQI and ESB exercise.Results: After 12-week exercise intervention, ESB improved sleep quality, latency, duration, disturbance and daytime dysfunction when compared to conventional exercise. In similar cases, the MV values in the EG were also higher than that in the CG (p = 0.009). ESB intervention could not affect the cardiac structure and left ventricular ejection fraction. Compared with the CG, the ESB intervention reduced PSQI scores and increased memorized word pairs (p < 0.001 for poor and normal sleepers in both unadjusted and adjusted analysis, p = 0.012 and 0.003 for poor and normal memory). The test of Pearson correlation coefficients showed that PSQI scores were strongly associated with the number of word pairs in both unadjusted and adjusted analyses (p < 0.0001).Conclusion: Eight-section brocade exercise improved sleep quality and memory consolidation and cardiopulmonary function by reducing PSQI scores, increasing word pairs and MV values in the older adults with AFAS.

Highlights

As a common disease, stroke severely threatens human health and life
We chose the baseline characteristics [age (Hokett and Duarte, 2019; Scullin et al, 2019), gender (Spencer, 2008), high blood pressure (Borda et al, 2019; Kumar et al, 2019), high blood lipids (Reijmer et al, 2009; Kruisbrink et al, 2017), diabetes (Margolis et al, 2019; Zhu et al, 2019), being overweight (MoraGonzalez et al, 2019; Yeo et al, 2019), atrial fibrillation (Takii et al, 2016; Yeung et al, 2019), smoking (Blaes et al, 2019; Cohen et al, 2019), family history of stroke (Baumann et al, 2012; Reeves et al, 2014), and history of transient ischemic attack (Takahashi et al, 2009; Sico et al, 2017)] according to previous reports indicating that these parameters would affect sleep and memory
The data were presented as median or mean values ± SD (Standard deviation). n = 84, 84, and 79 in the ESB group (EG) group and 81, 82, and 69 in the CG group before intervention, after intervention and at 12-week follow-up, respectively. n = 76, 76 and 74 in the EG group and 76, 64, and 65 in the CG group for total scores before intervention, after intervention and at 12-week follow-up, respectively

Summary

Introduction

Stroke severely threatens human health and life. The stroke disability rate is extremely high, and numerous patients show different levels of incapacity and lack the ability to take care of themselves, causing heavy burdens on themselves, their families, and society (Chhabra et al, 2019). The fundamental method to reduce the incidence, mortality, recurrence rates, and the degree of disability, is to prevent stroke risk. Epidemiological survey data show that the main risk factors of stroke include heart disease (Yuan et al, 2017), hypertension (Morrison and Filosa, 2019), diabetes (GonzalezPascual and Barea, 2019), obesity (Winter et al, 2016), and lack of exercise (Lee et al, 1999). Heart disease can directly increase the risk of stroke. Stroke prevention mainly comprises drug treatment (Hermann et al, 2019), acupuncture (Sun and Wu, 2019), and exercise (Zheng et al, 2019); the side effects of various drug therapies have become a causative factor (Alhaboob et al, 2014). Scholars are eager to find a safe and effective natural therapy for stroke
