Introduction: Frailty is common among patients entering cardiac rehabilitation (CR). Frailty is associated with poor health outcomes; however, it is unclear if frailty influences achieving goals in CR.

Methods: We report a secondary analysis of participants who were referred to an exercise and education-based CR program from 2005 to 2015.

Aims: Frailty among cardiac rehabilitation (CR) participants is associated with worse health outcomes. However, no literature synthesis has quantified the relationship between frailty and CR outcomes. The purpose of this study was to examine frailty prevalence at CR admission, frailty changes during CR, and whether frailty is associated with adverse outcomes following CR.

The frailty index (FI) uses a deficit accumulation approach to derive a single, comprehensive, and replicable indicator of age-related health status. Yet, many researchers continue to seek a single "frailty biomarker" to facilitate clinical screening. We investigated the prognostic accuracy of 70 individual biomarkers in predicting mortality, comparing each with a composite FI.

Background: Hospitalized older patients spend most of the waking hours in bed, even if they can walk independently. Excessive bedrest contributes to the development of frailty and worse hospital outcomes. We describe the study protocol for the Breaking Bad Rest Study, a randomized clinical trial aimed to promoting more movement in acute care using a novel device-based approach that could mitigate the impact of too much bedrest on frailty.

Aims: Examine the association between (1) admission frailty and (2) frailty changes during cardiac rehabilitation (CR) with 5-year outcomes (i.e. time to mortality, first hospitalization, first emergency department (ED) visit, and number of hospitalizations, hospital days, and ED visits).

Many patients with cardiovascular disease (CVD) are frail. Center-based cardiac rehabilitation (CR) can improve frailty; however, whether virtual CR provides similar frailty improvements has not been examined. To answer this question, we (1) compared the effect of virtual and accelerated center-based CR on frailty and (2) determined if admission frailty affected frailty change and CVD biomarkers.

Background: The effect of frailty and poor cardiovascular health on mortality for males and females is not fully elucidated. We investigated whether the combined burden of frailty and poor cardiovascular health is associated with all-cause and cardiovascular disease (CVD) mortality by sex and age.

Methods: We analyzed data of 35,207 non-institutionalized US residents aged 20-85 years old (mean age [standard deviation]: 46.

Background: physical activity reduces frailty in community-dwelling older adults. How exercise influences frailty in hospitalised older adults requires additional investigation.

Objectives: (i) to examine the impact of an exercise intervention on frailty in older adults admitted to an acute care ward, and (ii) to determine the impact of baseline frailty on the effectiveness of this intervention.

Engaging in health-promoting behaviours has health benefits for people with prediabetes or diabetes. People experience negative affect after diagnoses, which can impede self-regulation of health behaviours. Self-compassion, extending care to oneself in difficult times, can mitigate negative affect and promote self-regulation.

Article Synopsis
  • * Participants were assessed using accelerometers to measure MVPA in bouts (≥10 minutes) and sporadic activity (<1 minute), along with their sedentary habits.
  • * Results showed that higher bouted MVPA was linked to lower frailty in CVD participants, while prolonged ST negatively impacted frailty in those with CVD, indicating that both insufficient MVPA and prolonged ST are harmful regardless of CVD status.

Heterogeneity in aging can be explained by frailty. Lifestyle behaviors such as physical activity can help manage frailty levels. Conversely, sedentary behaviours are associated with frailty independently of physical activity.

Physical activity and sedentary behaviours are associated with frailty. However, it is unknown if different accumulation patterns of these behaviours are linked with frailty. Four studies were conducted: the first 3 determined if bouts of moderate-vigorous physical activity (MVPA) and patterns of sedentary behaviours were associated with frailty (study 1), and if sex (study 2) and cardiovascular disease (CVD) status (study 3) affected these associations.

Purpose: The purpose of this study was to examine whether meeting the Canadian Cardiovascular Society (CCS) ≤60-day wait time from cardiac rehabilitation (CR) referral to enrollment is associated with CCS patient-level quality indicator outcomes.

Methods: This pilot observational study consisted of 69 participants entering CR separated into 2 groups based on wait time (≤60-day, n = 45; >60-day, n = 24). Data were collected at baseline, and 1, 4 (CR completion), 6, and 12 months after baseline.

Background: There is little certainty as to the prevalence of frailty in Canadians in younger adulthood. This study examines and compares the prevalence of frailty in Canadians 18-79 years old using the Accumulation of Deficits and Fried models of frailty.

Methods: The Canadian Health Measures Study data were used to estimate the prevalence of frailty in adults 18-79 years old.
