Activities of Daily Living and Outcomes in Patients with Advanced Heart Failure

Addressing the functional needs of left ventricular assist device candidates: Development and feasibility of an occupational therapy pre-operative evaluation

BACKGROUND

Everyday living with a left ventricular assist device (LVAD) is complex, particularly for people with physical or cognitive impairments or limited social supports. There is a need for standardized pre-operative functional evaluations.

OBJECTIVES

Our objectives were to describe a pre-operative occupational therapy (OT) evaluation for LVAD candidates, assess its feasibility in routine care, and characterize functional needs.

METHODS

We retrospectively reviewed electronic medical records of pre-operative OT consultations for LVAD candidates over four years (n = 209). Occupational profile, vision, and sensation were operationalized from documentation narratives. Daily functioning was measured with Activity Measure for Post-Acute Care, grip strength with dynamometer, cognition with Montreal Cognitive Assessment and Allen Cognitive Level Screen-5, and LVAD self-management with a performance-based ordinal scale.

RESULTS

89.5 % of consultations were completed, averaging 61.2 min (n = 187): 79.1 % (148/187) inpatient and 20.9 % (39/187) outpatient. Patients completed 87.7 % (164/187) to 100.0 % (187/187) of evaluation components. 21.9 % (41/187) of candidates lived alone. 6.4 % (12/187) and 7.0 % (13/185) had visual and sensory dysfunction. 57.4 % were independent with daily activities (104/181). 17.7 % (32/181) had impaired grip strength. 69.3 % (124/179) had impaired cognition, 29.7 % (51/172) with impaired functional cognition for everyday activities. 88.4 % (145/164) required physical or cueing assistance while practicing LVAD batteries management. OTs interpreted that 20.9 % (39/187) would likely require 24/7 post-operative support with LVAD self-care.

CONCLUSION

Pre-operative OT evaluations were feasible and emphasized complex functional needs. Assessing LVAD self-care abilities may inform candidacy and facilitate early interventions to optimize functioning. OT should be consulted within interprofessional teams for all LVAD candidates.

The association of serum adiponectin level with activities of daily living in hospitalized elderly patients with heart failure

BACKGROUND

Several studies have reported a relationship between elevated serum adiponectin levels and poor outcomes in patients with heart failure (HF). However, data on the activities of daily living (ADL) in elderly patients with HF are limited.

METHODS

We evaluated 218 hospitalized elderly (≥65 years) patients with HF who underwent a comprehensive cardiac rehabilitation (CR) program during hospitalization. Serum adiponectin levels were measured before discharge. The Barthel index (BI) score was evaluated at discharge. Low ADL was defined as a BI score < 85.

RESULTS

Serum adiponectin levels were significantly associated with low ADL [p = 0.03; odds ratio (OR), 1.024, per 1.0 μg/mL increase]. In logistic or regression analyses adjusted for age, sex, body mass index, and estimated glomerular filtration rate, high adiponectin levels (≥16.2 μg/mL) were significantly associated with low ADL (p = 0.04; OR, 2.53), malnutrition (p < 0.01; OR, 2.88), and 6-min walk distance (p = 0.04; β = -17.5). In the multivariate analysis adjusted for conventional risk factors of low ADL, high adiponectin levels were also significantly associated with low ADL (p = 0.03; OR, 2.68). In the stepwise forward selection procedure, a high adiponectin level was an independent determinant of low ADL (p = 0.02; R2 = 0.0262). Both net reclassification improvement (0.53; p < 0.01) and integrated discrimination improvement (0.02; p = 0.01) improved significantly after the addition of high adiponectin level to conventional risk factors. In the regression analysis adjusted for age and sex, serum adiponectin levels were significantly (p < 0.0025) negatively associated with abdominal visceral and subcutaneous adipose tissue areas, body weight, body mass index, and serum triglyceride levels.

CONCLUSIONS

High serum adiponectin levels were not only significantly associated with an increased risk of low ADL, but also with an increased risk of malnutrition and low physical activity in elderly patients with HF after the in-hospital CR program.

Associations between activities of daily living, leisure activities and subjective well-being in Chinese older adults

OBJECTIVES

The study aimed to explore the internal pathway of the association between activities of daily living and subjective well-being among Chinese older adults using a large and representative sample.

BACKGROUND

There is still a lack of systematic investigation into the association between activities of daily living and subjective well-being among Chinese older adults.

MATERIALS AND METHODS

The study included 10 578 participants from the Chinese Longitudinal Healthy Longevity Survey. We applied multiple linear regression analysis and Spearman correlation analysis to examine the association between activities of daily living and subjective well-being and PROCESS macro to determine the mediating effect of leisure activities on the relationship between them.

RESULTS

The mean total score of subjective well-being was 30.5 ± 4.4. The prevalence of basic activities of daily living and instrumental activities of daily living limitations was 18.0% and 60.8%, respectively. Correlation analysis showed that activities of daily living score were negatively correlated with subjective well-being. Leisure activities were positively correlated with subjective well-being. The effect of instrumental activities of daily living on subjective well-being was partially mediated by leisure activities and leisure activities completely mediated the association between basic activities of daily living and subjective well-being.

CONCLUSIONS

The effect of instrumental activities of daily living on subjective well-being was partially mediated by leisure activities and leisure activities completely mediated the association between basic activities of daily living and subjective well-being.

Statin Therapy Induces Gut Leakage and Neuromuscular Disjunction in Patients With Chronic Heart Failure

ABSTRACT

Statins are commonly used to limit the risk of cardiovascular diseases, including ischemic heart attack and stroke. However, treatment often leads to myopathy and muscle weakness. Therefore, a better understanding of underlying pathomechanism is needed to improve the clinical outcomes. Here, we assessed the physical performance, including handgrip strength (HGS), gait speed (GS), and short physical performance battery, in 172 patients diagnosed with chronic heart failure (CHF) treated with (n = 50) or without (n = 122) statin and 59 controls. The plasma biomarkers, including sarcopenia marker C-terminal agrin fragment-22 (CAF22), intestinal barrier integrity marker zonulin, and C-reactive protein (CRP), were measured and correlated with the physical performance of patients. The HGS, short physical performance battery scores, and GS were significantly compromised in patients with CHF versus controls. Irrespective of etiology, significant elevation of plasma CAF22, zonulin, and CRP was observed in patients with CHF. There were strong inverse correlations of CAF22 with HGS (r 2 = 0.34, P < 0.0001), short physical performance battery scores (r 2 = 0.08, P = 0.0001), and GS (r 2 = 0.143, P < 0.0001). Strikingly, CAF22 and zonulin were positively correlated with each other (r 2 = 0.10, P = 0.0002) and with the level of CRP in patients with CHF. Further investigations revealed a significant induction of CAF22, zonulin, and CRP in patients with CHF taking statin versus nonstatin group. Consistently, HGS and GS were significantly lower in the statin versus nonstatin CHF patients' group. Collectively, statin therapy adversely affects the neuromuscular junction and intestinal barrier, which potentially induces systemic inflammation and physical disability in patients with CHF. Further prospective confirmation of the findings is required in a well-controlled study.

Using Latent Class Analysis to Identify Different Clinical Profiles Among Patients With Advanced Heart Failure

Context

Although palliative care is guideline-indicated for patients with advanced heart failure (HF), the scarcity of a specialty-trained palliative care workforce demands better identification of patients who are most burdened by the disease.

Objectives

We sought to identify latent subgroups with variations regarding symptom burden, functional status, and multimorbidity in an advanced HF population.

Methods

We performed a latent class analysis (LCA) of baseline data from a trial enrolling advanced HF patients. As LCA input variables, we chose indicators of HF severity, physical and psychological symptom burden, functional status, and the number of comorbidities.

Results

Among 563 patients, two subgroups emerged from LCA, Class A (352 [62.5%]) and Class B (211 [37.5%]). Patients in Class A were less often classified as NYHA class III or IV (88.0% vs. 97.5%, P < 0.001), as compared to Class B patients. Class A patients had fewer symptoms, fewer comorbidities, only 25.9% had impairments in activities of daily living (ADL), and virtually none suffered from clinically significant anxiety (0.4%) or depression (0.9%). In Class B, every patient reported more than three symptoms, almost all patients (92.6%) had some impairment in ADL, and nearly a third had anxiety (30.2%) or depression (28.3%). All-cause mortality after 12 months was higher in Class B, as compared to Class A (18.5% vs. 12.5%, P = 0.047).

Conclusion

Among advanced HF patients, we identified a distinct subgroup characterized by a conjunction of high symptom burden, anxiety, depression, multimorbidity, and functional status impairment, which might profit particularly from palliative care interventions. J Pain Symptom Manage 2022;000:1-9.
