Background: This study analyzed the effect of walking breaks or low-volume high-intensity interval exercise (LV-HIIE) on markers of metabolic syndrome relative to a day of prolonged sitting. Methods: Twenty-five adults with excess body fat participated in this crossover trial: (1) 10-hour sitting day (SIT), (2) LV-HIIE followed by a sitting day (EX+SIT), and (3) sitting day with 5-minute walking breaks for every 20 minutes (SIT+WB). Glucose and blood pressure (BP) were measured before and 1 hour after 4 meals and 2 hours after lunch. Triglycerides were measured at baseline, 2, and 3.5 hours after lunch. Generalized mixed models were used to identify differences in the area under the curve (AUC) of BP and incremental AUC (iAUC) of glucose and triglycerides among the sessions. Results: iAUC-glucose was lower in SIT+WB than SIT (β = -35.3 mg/dL·10 h; 95% confidence interval, -52.5 to -8.2). AUC-diastolic BP was lower in SIT+WB than SIT (β = -14.1 mm Hg·10 h; 95% confidence interval, -26.5 to -1.6) and EX+SIT (β = -14.5 mm Hg·10 h; 95% confidence interval, -26.9 to -2.1). There were no differences in triglycerides and systolic BP levels among the sessions. Conclusion: Adults with excess body fat present lower glucose and diastolic BP during a day with breaks in sitting time compared with a prolonged sitting day with or without an LV-HIIE session.

The aim of this study was to determine whether self-compassion—orientation to care for oneself during challenges—helps people at risk of cardiovascular disease deal with emotional reactions and assist with self-regulating health behaviors. This observational study recruited women (N = 102) who attended three research visits over 3 weeks to gather information on emotions, intentions, and engagement in health behaviors after women received news they were at risk of cardiovascular disease. Self-compassion negatively associated with emotional responses and associated with intentions and engagement in health behaviors after receiving news of their cardiovascular disease risk. Self-compassion was associated with adaptive lifestyle behaviors. [ABSTRACT FROM AUTHOR]

While previous investigations have demonstrated the benefit of cardiac rehabilitation (CR) on outcomes after cardiac surgery, the association between pre-operative frailty and post-operative CR completion is unclear. The purpose of this retrospective cohort study was to determine if pre-operative frailty scores impacted CR completion post-operatively and if CR completion influenced frailty scores in 114 cardiac surgery patients. Frailty was assessed with the use of the Clinical Frailty Scale (CFS), the Modified Fried Criteria (MFC), the Short Physical Performance Battery (SPPB), and the Functional Frailty Index (FFI). A Mann-Whitney test was used to compare frailty scores between CR completers and non-completers and changes in frailty scores from baseline to 1-year post-operation. CR non-completers were more frail than CR completers at pre-operative baseline based on the CFS (p = 0.01), MFC (p < 0.001), SPPB (p = 0.007), and the FFI (p < 0.001). A change in frailty scores from baseline to 1-year post-operation was not detected in either group using any of the four frailty assessments. However, greater improvements from baseline to 1-year post-operation in two MFC domains (cognitive impairment and low physical activity) and the physical domain of the FFI were found in CR completers as compared to CR non-completers. These data suggest that pre-operative frailty assessments have the potential to identify participants who are less likely to attend and complete CR. The data also suggest that frailty assessment tools need further refinement, as physical domains of frailty function appear to be more sensitive to change following CR than other domains of frailty.

The wait before elective cardiac intervention or surgery presents an opportunity to prevent further physiologic decline preoperatively in older patients. Implementation of prehabilitation programs decreases length of hospital stay postoperatively, decreases time spent in the intensive care unit, decreases postoperative complications, and improves self-reported quality of life postsurgery. Prehabilitation programs should adopt multimodal approaches including nutrition, exercise, and worry reduction to improve patient resilience in the preoperative period. High-quality research in larger cohorts is needed, and interventions focusing on underrepresented frailer populations and women. Creative ways to improve accessibility, adherence, and benefits received from prehabilitation should be explored., (Copyright © 2019 Elsevier Inc. All rights reserved.)
