Handgrip strength to screen early-onset sarcopenia in heart failure.

BACKGROUND & AIMS: Sarcopenia in heart failure (HF) is associated with severe outcomes, increased mortality, and high healthcare cost burden. Systematic muscle screening in patients with chronic HF would improve quality and appropriateness of care. Here we tested handgrip strength (HGS) as a screening tool for sarcopenia in patients with chronic HF, using the EWGSOP 2010 and 2019 reference-standard definitions of sarcopenia. METHODS: HF inpatients, aged 65 years old or above, were prospectively included between November 2014 and September 2018, and relevant sociodemographic, anthropometric and HF characterization data was collected. The accuracy of HGS as a screening test for sarcopenia was assessed by gender using area under the receiver operating characteristic (ROC) curves (AUC). RESULTS: The population consisted of 118 older patients (age: 78.9 yrs; BMI: 26.6 kg/m2) with a mean HGS of 16.1 kg (SD 4.6) in women and 26.5 kg (SD 6.7) in men. Factors associated with HGS were age (p = 0.005), Instrumental Activity of Daily Living (p = 0.001), and heart rate (p = 0.034). Screening was positive (patients confirmed as sarcopenic by the HGS test) with cut-off values of 18 kg for women and 27 kg for men, with ROC analysis giving a sensitivity of 85.7% in women and 88.2% in men. CONCLUSIONS: HGS can be used as a valid tool to screen for sarcopenia in older (≥65 yrs) patients with chronic HF. CLINICAL TRIAL REGISTRATION: NCT03153774.

Sarcopenia in patients after an episode of acute decompensated heart failure: An underdiagnosed problem with serious impact.

BACKGROUND & AIMS: Sarcopenia is a multifactorial syndrome resulting in a decrease in both muscle mass and function. Little is known about the prevalence and prognostic impact of sarcopenia in patients with acutely decompensated chronic heart failure (ADHF). We aimed to evaluate the prevalence (main endpoint) and impact of sarcopenia on ADHF patients. METHODS: 140 ADHF patients were enrolled between November 2014 and September 2018 in a multicenter prospective longitudinal study. A similar, independent multi-departmental cross-sectional study in 165 ADHF patients was used for external validation of prevalence data. All subjects were assessed on the European Working Group on Sarcopenia criteria. RESULTS: Ninety-one patients (65%) had sarcopenia (vs. 53.6% in the external replication regional cohort). Patients with sarcopenia were older and more likely to have eGFR <60 ml/min/1.73 m2 (p < 0.001 and p = 0.002). Sarcopenia was associated with impaired functional status [lower 6 min walking test (220 ± 108 vs. 279 ± 170, p = 0.03) and 4 m gait speed (0.56 ± 0.24 vs. 0.80 ± 0.37, p < 0.001)] and autonomy [Instrumental activities of daily living: 6.7 ± 1.4 vs. 7.3 ± 1.2, p = 0.005]. Over up to 4 years' follow-up, 30 cardiovascular (CV) deaths and 42 non-CV deaths occurred. In a multivariable analysis, sarcopenia was associated with time to first non-CV hospitalization (hazard ratio 1.93; 95% confidence interval 1.14-3.24; p = 0.014) but not with any other hospitalization, any mortality endpoint, or a composite endpoint of CV death and HF hospitalization. CONCLUSIONS: The prevalence of sarcopenia in ADHF patients is high and associated with greater risk of non-CV hospitalizations, highlighting the importance of identifying and managing the condition in a multidisciplinary approach.

Epidemiological characteristics and therapeutic management of patients with chronic heart failure who use smartphones: Potential impact of a dedicated smartphone application (report from the OFICSel study).

BACKGROUND: The effectiveness of transitional care services for patients discharged from hospital after acute heart failure is challenging, especially in terms of reducing subsequent heart failure hospitalizations. The increased adoption of smartphone applications in society offers a new opportunity to interact with patients to avoid rehospitalization. Thus, electronic health (e-health) can enhance the impact of existing therapeutic education programmes. AIMS: To determine the prevalence of smartphone use among patients with chronic heart failure, and to assess the epidemiological characteristics and therapeutic management of these patients, with a broader aim of developing smartphone-based therapeutic education programmes for patients. METHODS: The French Observatoire français de l'insuffisance cardiaque et du sel (OFICSel) registry was conducted in 2017 by 300 cardiologists, and included both inpatients and outpatients who had been hospitalized for heart failure at least once in the previous 5 years. Data collection included demographic and heart failure-related variables, which were provided by the cardiologist and by the patient via a questionnaire. RESULTS: Among the 2822 patients included, 2517 completed the questionnaire. Of this total, 907 patients (36%) were smartphone users. Compared with non-users, smartphone users were younger, were more frequently men, more frequently lived in cities, had a higher educational level and were more frequently professionally active. Smartphone users less frequently had diabetes, hypertension, atrial fibrillation or ischaemic cardiopathy. Only 22% of patients were actively participating in a therapeutic education programme. CONCLUSION: Smartphones were used by more than one-third of patients with heart failure in France in 2017, underscoring the feasibility of developing a smartphone application to deliver therapeutic education to the population with chronic heart failure.

Effectiveness of combined eccentric and concentric exercise over traditional cardiac exercise rehabilitation programme in patients with chronic heart failure: protocol for a randomised controlled study.

INTRODUCTION: Exercise-based rehabilitation is a standard feature of chronic heart failure management. The effectiveness of eccentric exercise could offer new opportunities for better tailoring rehabilitation programme to patients' limitations. The goal of the study is to contrast the impact of a mixed eccentric and concentric cycling training programme, to that of conventional concentric cycling rehabilitation in patients with chronic heart failure (peak oxygen consumption (VO2Peak) < 15 mL⋅kg-1⋅min-1, ejection fraction <40%). METHODS AND ANALYSIS: It is a prospective, open, controlled and randomised study (2×25 subjects) carried out in a single centre. Subjects will perform five exercise sessions per week per the randomisation outcome, with the intervention group performing eccentric in three of the five weekly sessions while the control group will perform the five sessions of concentric exercise. Cycling intensity will be the same in both groups and fixed to the power associated with the first ventilatory threshold. Self-management education programme, callisthenics sessions and muscle strength trainings will also be carried out as for any heart failure patient normally included in the rehabilitation programme. The primary outcome will be the change in distance covered during the 6 min walk test. Secondary outcomes will include other physical mobility parameters, functional exercise capacities, quality of life and body composition as well as skeletal muscle properties including mitochondrial function parameters. ETHICS AND DISSEMINATION: The study has been approved by the institutional ethics review board (17.079) and the French regulatory authority for research (2017-A00969-44). Adverse events that could occur during the protocol will be reported to the principal investigator. The results will be published in an international peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT03716778.

Since 2011, thanks to the cooperation of frontline healthcare professionals, it has provided care to more than 1 200 patients across the Auvergne health region. The organisation, blending telemedicine and human contact, has made this initiative a successful example of how the boundaries between community and hospital healthcare can be removed.
