Objective: We aimed to characterize patients after an acute cardiac event regarding their negative expectations around returning to work and the impact on work capacity upon discharge from cardiac rehabilitation (CR)., Methods: We analyzed routine data of 884 patients (52±7 years, 76% men) who attended 3 weeks of inpatient CR after an acute coronary syndrome (ACS) or cardiac surgery between October 2013 and March 2015. The primary outcome was their status determining their capacity to work (fit vs unfit) at discharge from CR. Further, sociodemographic data (eg, age, sex, and education level), diagnoses, functional data (eg, exercise stress test and 6-min walking test [6MWT]), the Hospital Anxiety and Depression Scale (HADS) and self-assessment of the occupational prognosis (negative expectations and/or unemployment, Würzburger screening) at admission to CR were considered., Results: A negative occupational prognosis was detected in 384 patients (43%). Out of these, 368 (96%) expected not to return to work after CR and/or were unemployed before CR at 29% (n=113). Affected patients showed a reduced exercise capacity (bicycle stress test: 100 W vs 118 W, P <0.01; 6MWT: 380 m vs 421 m, P <0.01) and were more likely to receive a depression diagnosis (12% vs 3%, P <0.01), as well as higher levels on the HADS. At discharge from CR, 21% of this group (n=81) were fit for work (vs 35% of patients with a normal occupational prognosis (n=175, P <0.01)). Sick leave before the cardiac event (OR 0.4, 95% CI 0.2-0.6, P <0.01), negative occupational expectations (OR 0.4, 95% CI 0.3-0.7, P <0.01) and depression (OR 0.3, 95% CI 0.1-0.8, P =0.01) reduced the likelihood of achieving work capacity upon discharge. In contrast, higher exercise capacity was positively associated., Conclusion: Patients with a negative occupational prognosis often revealed a reduced physical performance and suffered from a high psychosocial burden. In addition, patients' occupational expectations were a predictor of work capacity at discharge from CR. Affected patients should be identified at admission to allow for targeted psychosocial care., Competing Interests: The authors report no conflicts of interest in this work., (© 2019 Salzwedel et al.)

Background: Elderly patients are a growing population in cardiac rehabilitation (CR). As postural control declines with age, assessment of impaired balance is important in older CR patients in order to predict fall risk and to initiate counteracting steps. Functional balance tests are subjective and lack adequate sensitivity to small differences, and are further subject to ceiling effects. A quantitative approach to measure postural control on a continuous scale is therefore desirable. Force plates are already used for this purpose in other clinical contexts, therefore could be a promising tool also for older CR patients. However, in this population the reliability of the assessment is not fully known.Research Question: Analysis of test-retest reliability of center of pressure (CoP) measures for the assessment of postural control using a force plate in older CR patients.Methods: 156 CR patients (≥75 years) were enrolled. CoP measures (path length (PL), mean velocity (MV), and 95% confidence ellipse area (95CEA)) were analyzed twice with an interval of two days in between (bipedal narrow stance, eyes open (EO) and closed (EC), three trials for each condition, 30 s per trial), using a force plate. For test-retest reliability estimation absolute differences (Δ: T0-T1), intraclass correlation coefficients (ICC) with 95% confidence intervals, standard error of measurement and minimal detectable change were calculated.Results: Under EO condition ICC were excellent for PL and MV (0.95) and good for 95CEA (0.88) with Δ of 10.1 cm (PL), 0.3 cm/sec (MV) and 1.5 cm2 (95CEA) respectively. Under EC condition ICC were excellent (≥ 0.95) for all variables with larger Δ (PL: 21.7 cm; MV: 0.7 cm/sec; 95CEA: 2.4 cm2).Significance: In older CR patients, the assessment of CoP measures using a force plate shows good to excellent test-retest reliability.
