Abstract

Purpose: Exercise performance and quality of life (QoL) of left ventricular assist device (LVAD) patients improve after early cardiac rehabilitation (CR). The purpose of this study was to examine the efficacy of multiprofessional long term phase 3 outpatient CR, and whether cardiopulmonary exercise testing (CPX) and 6-min walk testing (6MWT) post-LVAD implantation predict hospital readmission.

Methods: This retrospective observational cohort study included 29 LVAD patients (58.6 ± 7.7 yr, female: 13.8%, body mass index: 29.4 ± 3.3 kg/m 2 ). Functional performance tests (CPX, 6MWT, sit-to-stand test), QoL, and psychological surveys (Kansas City Cardiomyopathy Questionnaire, hospital anxiety and depression scale, and Control Convictions about Disease and Health [KKG]) were performed at baseline and at the end of CR.

Results: The CR was initiated at a median (IQR) of 159 (130-260) d after LVAD implantation for a duration of 340 (180-363) d with 46.8 ± 23.2 trainings. The 6MWT (408.4 ± 113.3 vs 455.4 ± 115.5 m, P = .003) and sit-to-stand test (16.7 ± 6.9 vs 19.0 ± 5.3 repetitions, P = .033) improved, but relative peak oxygen uptake (V˙ o2peak : 9.4 [8.2-14.4] vs 9.3 [7.8-13.4] mL/min/kg, P = .57) did not change. Using receiver operating characteristic curve analysis, baseline V˙ o2peak values were associated with readmission 1-yr after CR onset (C-statistic = 0.88) with a cutoff value of V˙ o2peak < 9.15 mL/min/kg (100% sensitivity, 78% specificity, P < .001). The Kansas City Cardiomyopathy Questionnaire self-efficacy and knowledge (+6.3 points), QoL (+5.0 points), and social limitation (+7.1 points) demonstrated clinically important changes. In addition, the hospital anxiety and depression scale showed a significant reduction in anxiety (4.6 ± 3.2 vs 2.6 ± 2.4, P = .03).

Conclusions: Long-term CR is safe and LVAD outpatients showed improvement of QoL, anxiety, and submaximal exercise performance. In addition, V˙ o2peak and 6MWT have prognostic value for readmission.

长期门诊心脏康复后左室辅助装置患者的运动表现和生活质量。

目的:早期心脏康复(CR)后，左室辅助装置(LVAD)患者的运动表现和生活质量(QoL)得到改善。本研究的目的是检验多专业长期3期门诊CR的疗效，以及lvad植入后心肺运动试验(CPX)和6分钟步行试验(6MWT)是否能预测再入院。方法:回顾性观察队列研究纳入29例LVAD患者(58.6±7.7岁，女性:13.8%，体重指数:29.4±3.3 kg/ m2)。功能表现测试(CPX、6MWT、坐立测试)、生活质量和心理调查(堪萨斯城心肌病问卷、医院焦虑和抑郁量表，以及疾病和健康控制信念[KKG])在CR基线和CR结束时进行。结果:CR开始于LVAD植入后的中位(IQR)为159 (130-260)d，持续时间为340 (180-363)d，训练时间为46.8±23.2。6MWT(408.4±113.3 vs 455.4±115.5 m, P = 0.003)和坐立试验(16.7±6.9 vs 19.0±5.3,P = 0.033)得到改善，但相对峰值摄氧量(V˙o2峰:9.4 [8.2-14.4]vs 9.3 [7.8-13.4] mL/min/kg, P = 0.57)没有变化。通过受试者工作特征曲线分析，基线V˙o2峰值与CR发病后1年再入院相关(c -统计量= 0.88)，截断值V˙o2峰值< 9.15 mL/min/kg(100%敏感性，78%特异性，P < 0.001)。堪萨斯城心肌病问卷的自我效能和知识(+6.3分)、生活质量(+5.0分)和社会限制(+7.1分)表现出临床重要的变化。此外，医院焦虑和抑郁量表显示焦虑显著降低(4.6±3.2 vs 2.6±2.4,P = 0.03)。结论:长期CR是安全的，LVAD门诊患者的生活质量、焦虑和亚极限运动表现均有改善。此外，V˙o2峰值和6MWT对再入院有预测价值。

期刊介绍： JCRP was the first, and remains the only, professional journal dedicated to improving multidisciplinary clinical practice and expanding research evidence specific to both cardiovascular and pulmonary rehabilitation. This includes exercise testing and prescription, behavioral medicine, and cardiopulmonary risk factor management. In 2007, JCRP expanded its scope to include primary prevention of cardiovascular and pulmonary diseases. JCRP publishes scientific and clinical peer-reviewed Original Investigations, Reviews, and Brief or Case Reports focused on the causes, prevention, and treatment of individuals with cardiovascular or pulmonary diseases in both a print and online-only format. Editorial features include Editorials, Invited Commentaries, Literature Updates, and Clinically-relevant Topical Updates. JCRP is the official Journal of the American Association of Cardiovascular and Pulmonary Rehabilitation and the Canadian Association of Cardiac Rehabilitation.
