Handgrip strength in patients with acute decompensated heart failure: Accuracy as a predictor of malnutrition and prognostic value

A predictive model based on the GLIM diagnosis for malnutrition in older adult heart failure patients

Background and aims

Malnutrition is closely associated with adverse clinical outcomes in older adult heart failure (HF) patients. Currently, there is a distinct absence of specific diagnostic tools to identify malnutrition within this particular population. Therefore, this study aims to analyze the factors influencing malnutrition in older adult HF patients based on the Global Leadership Initiative on Malnutrition (GLIM) criteria, with the goal of developing a rapid and accurate diagnostic method to identify malnutrition.

Methods

The research incorporated a primary cohort study of 163 HF patients aged 65 and above and a validation cohort of 69 patients. The nutritional status of these patients was assessed according to the GLIM criteria. Logistic regression analysis was conducted to determine the independent risk factors of malnutrition. Subsequently, a nomogram model was developed and validated.

Results

According to the GLIM criteria, 54 patients (33.1%) and 22 patients (32.4%) in two patient cohorts were suffering from malnutrition. The logistic analyses revealed that body mass index (BMI), grip strength, mid-upper arm circumference (MUAC), fat-free mass (FFM), and albumin independently serve as risk factors of malnutrition in older adult HF patients. The nomogram model demonstrates excellent discriminative ability, with an area under the curve (AUC) of 0.921 (95% CI: 0.881-0.962). While the AUC of validation cohort is 0.899 (95% CI: 0.827-0.972).

Conclusion

In older adult HF patients, BMI, grip strength, FFM, MUAC and albumin are identified as independent risk factors for malnutrition. The constructed nomogram based on these factors can accurately predict malnutrition and holds significant practical value.

Are sarcopenia and its individual components linked to all-cause mortality in heart failure? A systematic review and meta-analysis

OBJECTIVE

The objective of this systematic review and meta-analysis was to assess sarcopenia and its components as prognostic factors in patients with heart failure (HF).

METHODS

From inception to December 2022, a systematic literature search was carried out utilizing PubMed, Web of Science, Scopus, and Cochrane Library databases. A meta-analysis employing a random-effects model was performed to assess the pooled effects.

RESULTS

The systematic review and meta-analysis included 32 and 18 longitudinal studies, respectively. The prediction of 1- to 2-year all-cause mortality in sarcopenia was not statistically significant (hazard ratio (HR): 1.35, 95% CI 0.76-2.38, I2 = 54%, P = 0.31). The lowest combined quartile and quantile of the population were used to define low handgrip strength that showed identical results (HR: 1.24, 95% CI 0.94-1.62, I2 = 0%, P = 0.13). Low L3-L4 psoas muscle mass (HR: 2.20, 95% CI 1.26-3.83, I2 = 87%, P < 0.01) and slow gait speed (HR: 1.45, 95% CI 1.20-1.74, I2 = 0%, P < 0.01) were significant contributors to all-cause mortality risk. Additionally, a 0.1 m/s increase in gait speed demonstrated a significant reduction of all-cause mortality (HR: 0.77, 95% CI 0.66-0.90, I2 = 60%, P < 0.01). Our narrative synthesis also described appendicular lean mass (ALM) and short physical performance battery (SPPB) scores as significant prognostic factors.

CONCLUSIONS

Compared to patients with higher overall functional performance, those with HF and low ALM, low psoas muscle mass, low SPPB, and slow gait speed are at an increased risk of all-cause mortality. Early prevention and/or treatment of lower limb physical function deterioration may be an essential strategy to reduce the risk of premature death in HF.

Exploring the potential of handgrip strength as a prognostic marker in acute decompensated heart failure with reduced ejection fraction: a cross-sectional study

Frailty is associated with poor outcomes in heart failure (HF). Handgrip strength (HGS) is a simple indicator of Physical frailty. We aimed to assess the prognostic value of HGS in patients under 60 years old with acute decompensated HF with reduced ejection fraction (HFrEF). In this cross-sectional study, we enrolled 125 patients with acute decompensated HFrEF. HGS was measured using a manual dynamometer. The primary outcome was in-hospital mortality. Univariate logistic regression analysis was performed to identify risk factors associated with in-hospital mortality. Receiver operating characteristic (ROC) curve analysis was used to assess the predictive value of HGS for in-hospital mortality. The in-hospital mortality rate was 16%. Survivors had numerically higher, though not statistically significant, median HGS compared to non-survivors (18.8 (IQR: 13.2-25.3) kg vs. 13 (IQR: 11.4-19.5) kg; p = 0.06). HGS showed negative correlation with length of stay (rho = - 0.202, p = 0.024) and NT-proBNP levels (rho = - 0.256, p = 0.004). The area under the ROC curve for overall HGS predicting in-hospital mortality was 0.630 (p = 0.043). Lower left ventricular ejection fraction and higher NT-proBNP levels were significantly associated with increased odds of in-hospital mortality in univariate analysis. Lower handgrip strength was associated with longer hospital stay and higher NT-proBNP levels, and demonstrated a modest ability to predict in-hospital mortality. However, further research is necessary to establish standardized measurement methods and optimal prognostic thresholds before handgrip strength can be widely implemented in the management of this patient population.

Preoperative muscle function assessments in nursing as predictors of postoperative outcomes in patients with colorectal cancer and malnutrition

Background

Patients with colorectal cancer (CRC) often present with malnutrition upon admission, which is associated with a poor prognosis. However, current traditional tools for diagnosing malnutrition do not assess muscle function. This study aims to explore whether the evaluation of muscle function has predictive value for the prognosis of CRC patients with malnutrition.

Methods

We retrospectively analyzed the clinical parameters of patients with CRC and malnutrition based on the Global Leadership Initiative on Malnutrition criteria who underwent radical surgery at our center from 2015 to 2021. Patients were grouped according to their preoperative muscle function assessments. The clinical characteristics and postoperative outcomes were compared between the groups. The risk factors for postoperative complications were analyzed.

Results

A total of 346 patients were included in the study. Patients with low handgrip strength had higher incidences of total (p = 0.001), surgical (p = 0.015) and medical (p = 0.024) complications and longer postoperative hospital stays (p = 0.026). Patients with low gait speed had higher incidences of total (p = 0.027) and medical (p = 0.004) complications. Low handgrip strength was an independent risk factor for total (p = 0.008) complications, surgical (p = 0.038) complications and overall survival (p = 0.003). Low gait speed was an independent risk factor for medical complications (p = 0.021).

Conclusion

For malnourished CRC patients, preoperative assessment of muscle function during perioperative care can predict adverse postoperative outcomes and can be incorporated into a comprehensive nutritional management plan.

Malnutrition in heart failure. The importance of assessing for congestion and sarcopenia

AIM

This work aims to describe nutrition and sarcopenia in inpatients with heart failure (HF). It also aims to assess factors associated with in-hospital and short-term prognosis related to nutrition and sarcopenia.

METHODS

We collected data on consecutive HF patients admitted to a single center's internal medicine ward. Patients were recruited in May and October 2021. Malnutrition was determined by the Mini Nutritional Assessment-Short Form (MNA-SF) and sarcopenia by the screening test, SARC-F scale, and handgrip strength test.

RESULTS

190 patients were analyzed, mean age 82.1 (±8.2), 54.2% women, median follow up 106 days. Patients were classified into three groups based on MNA-SF score: group 1 (12-14 points, no risk) included 50 patients, group 2 (8-12 points, high risk of malnutrition) included 81 patients, group 3 (0-7 points, malnourished) included 59 patients. Group 3 had significantly more inflammation (lower albumin and higher C-reactive Protein (CRP)) and congestion (measured by NT-ProBNP levels). In-hospital mortality was related to poor muscle function, CRP, and NT-ProBNP, but not to malnutrition. The poorest short-term outcomes were related to malnutrition and comorbidity. However, when the variable of muscle function was introduced, it could act as a poor prognostic factor related to CRP and NT-ProBNP, which were the main determinants of survival.

CONCLUSION

In malnourished patients with HF, inflammation and congestion were related to in-hospital mortality. Malnutrition along with comorbidity may play a role in decreasing short-term survival. Early identification through proactive nutritional and functional screenings should be a key element of assessing HF patients.

Assessing the predictive value of the controlling nutritional status score on all-cause mortality during hospitalization in patients with acute decompensated heart failure: a retrospective cohort study from Jiangxi, China

Objective

Nutritional status is closely associated with the prognosis of heart failure. This study aims to assess the relationship between the Controlling Nutritional Status (CONUT) score and in-hospital mortality among patients with acute decompensated heart failure (ADHF) in Jiangxi, China.

Methods

A retrospective cohort study was conducted. Multivariable Cox regression models and restricted cubic spline regression were employed to evaluate the relationship between the CONUT score and in-hospital mortality in ADHF patients from Jiangxi, China. The predictive value of the CONUT score for in-hospital mortality in ADHF patients was analyzed using receiver operating characteristic curves. Subgroup analyses were performed to identify risk dependencies of the CONUT score in specific populations.

Results

The study included 1,230 ADHF patients, among whom 44 (3.58%) mortality events were recorded. After adjusting for confounding factors, a positive correlation was found between the CONUT score and the risk of in-hospital mortality in ADHF patients. Restricted cubic spline regression analysis indicated a non-linear relationship between the CONUT score and the risk of in-hospital mortality in ADHF patients, estimating a rapid increase in mortality risk when the CONUT score exceeded 5. Receiver operating characteristic analysis demonstrated a good predictive value of the CONUT score for all-cause mortality events in ADHF patients [area under the curve = 0.7625, optimal threshold = 5.5]. Additionally, a relatively higher risk associated with the CONUT score was observed in male patients and those with concomitant cerebral infarction.

Conclusion

This study reveals a positive correlation between the CONUT score and the risk of in-hospital mortality in ADHF patients. Based on the findings of this study, we recommend maintaining a CONUT score below 5 for patients with ADHF in Jiangxi, China, as it may significantly contribute to reducing the risk of in-hospital all-cause mortality.

Long-Term Maintenance of Normal Serum Vitamin B1 Levels Is Associated with Better Outcomes in Patients with Heart Failure

Deficiency of vitamin B1 (VB1), an essential micronutrient, causes heart failure (HF). A recent randomized controlled trial failed to show any improvement in HF prognosis after short-term VB1 supplementation. In the current study, we investigated the efficacy of long-term maintenance of normal blood VB1 levels in preventing adverse outcomes in patients with HF.This study included 88 consecutive patients with HF who received guideline-directed medical therapy at Arida Municipal Hospital. The patients were divided into 3 groups: a control group with normal VB1 levels and no VB1 supplementation (normal group, n = 25), and those presenting with VB1 deficiency, who either required short-term VB1 supplementation (short-term supplementation group, n = 25), or long-term maintenance of normal blood VB1 levels (long-term maintenance group, n = 38). The time to the first appearance of composite outcomes, including cardiovascular death and hospitalization for HF, was compared between the 3 groups.VB1 deficiency was observed in 63 (72%) patients. The Kaplan-Meier curve showed that the long-term maintenance group had better outcomes than the other 2 groups. In the multivariate analysis, long-term maintenance of normal blood VB1 levels and age were independent predictors of composite outcomes.VB1 deficiency is frequently observed, and the long-term maintenance of normal blood VB1 levels may result in better outcomes in patients with HF. Our results suggest that the detection of VB1 deficiency and long-term restoration of VB1 levels may be part of the overall therapeutic strategy for HF.

Inspiratory muscle endurance is similarly reduced in the early and late stages of chronic Chagas heart disease

OBJECTIVE

Inspiratory muscle strength (IMS) appears to be reduced in subjects with chronic Chagas heart disease (CHD), especially in the presence of heart failure (HF). However, only one study about IMS and inspiratory muscle endurance (IME) in those with CHD without heart failure is available. This study aimed to compare IMS and IME in subjects with CHD in the presence and absence of HF.

METHODS

This is a cross-sectional study in which 30 CHD adult patients were divided into CHD-CC group (initial phase of CHD, without HF; n = 15) and CHD-HF group (advanced phase of CHD, with HF; n = 15). We assessed IMS by maximum inspiratory pressure (MIP) and IME by incremental (Pthmax) and constant load (TLim) tests. Reduced IMS and IME were considered by predicted MIP values <70% and Pthmax/MIP <75%, respectively.

RESULTS

Inspiratory muscle weakness (IMW) was more frequent in CHD-HF than in CHD-CC (46.7% vs. 13.3%; p = 0.05), and both groups had high frequencies of reduced IME (93.3% CHD-CC vs. 100.0% CHD-HF; p = 0.95). Age-adjusted logistic regression analysis using HF as a dependent variable showed that HF was associated with an increased chance of IMW compared with the CHD-CC group (OR = 7.47; p = 0.03; 95% CI 1.20-46.19).

CONCLUSION

This study suggests that, in patients with CHD, HF is associated with IMW, and that reduction of IME is already present in the initial phase, similar to the advanced phase with HF.

Causal relationship between nutritional assessment phenotypes and heart failure: A Mendelian randomization study

Introduction

Malnutrition is strongly associated with heart failure (HF); however, the causal link remains unclear. We used Mendelian randomization (MR) to infer causal associations between different nutritional assessment phenotypes and HF and to analyze whether these associations were mediated by common HF risk factors.

Methods

Two-sample bidirectional MR was used to infer causal associations between nutritional assessment phenotypes and HF. Mutual influences between different nutritional assessment phenotypes and potential correlations were estimated using multivariate MR methods. Two-step MR was used to quantify the mediating effects of common HF risk factors on the causal associations.

Results

Three phenotypes were positively associated with the development of HF: waist circumference (WC) (odds ratio [OR] = 1.74; 95% confidence interval [CI], 1.60-1.90; P = 3.95 × 10-39), body mass index (BMI) (OR = 1.70; 95%CI, 1.60-1.80; P = 1.35 × 10-73), and whole body fat mass (WBFM) (OR = 1.54; 95%CI, 1.44-1.65; P = 4.82 × 10-37). Multivariate MR indicated that WBFM remained positively associated with HF after conditioning on BMI and WC (OR = 2.05; 95%CI, 1.27-3.31; P = 0.003). Three phenotypes were negatively correlated with the development of HF: usual walking pace (UWP) (OR = 0.40; 95%CI, 0.27-0.60; P = 8.41 × 10-6), educational attainment (EA) (OR = 0.73; 95%CI, 0.67-0.79; P = 2.27 × 10-13), and total cholesterol (TC) (OR = 0.90; 95%CI, 0.84-0.96; P = 4.22 × 10-3). There was a bidirectional causality between HF and UWP (Effect estimate = -0.03; 95%CI, -0.05 to -0.01; P = 1.95 × 10-3). Mediation analysis showed that common risk factors for HF (hypertension, coronary artery disease, cardiomyopathy, and valvular heart disease) mediated these causal associations (all P < 0.05).

Conclusions

BMI, WC, and WBFM are potential risk factors for HF, and the correlation between WBFM and HF was significantly stronger than that between BMI and WC, and HF. EA, UWP, and TC are potential protective factors against HF. Common risk factors for HF mediate these causal pathways. Early identification of potential risk or protective factors for HF patients from the dimension of nutritional status is expected to further improve patient outcomes.

Predictive value of Global Leadership Initiative on Malnutrition criteria combined with handgrip strength for postoperative outcomes in overweight colorectal cancer patients

BACKGROUND AND AIM

The Global Leadership Initiative on Malnutrition (GLIM) criteria are increasingly used to assess the nutritional status of hospitalized patients and predict the prognosis of patients with malignant tumors; however, malnutrition is often overlooked in overweight individuals, such as colorectal cancer patients. This study aimed to investigate the predictive value of the GLIM criteria combined with handgrip strength (HGS) in overweight colorectal cancer patients.

METHODS

This retrospective study enrolled overweight patients who underwent radical resection for colorectal cancer at two centers between 2015 and 2021. Malnutrition was diagnosed based on the GLIM criteria. Skeletal muscle mass was assessed using the skeletal muscle index, and skeletal muscle function was assessed using the HGS test. The risk factors for complications and survival were also evaluated.

RESULTS

A total of 850 patients were enrolled in the study. The incidence of malnutrition in the GLIM and HGS-GLIM groups was 12.4% and 6.4%, respectively. The incidence of total complications in both the malnutrition groups was significantly higher than that in the control group. Patients in the HGS-GLIM-malnutrition group had worse overall survival and disease-free survival. HGS-GLIM was independently associated with postoperative complications (P = 0.046), overall survival (P = 0.037), and disease-free survival (P = 0.047).

CONCLUSION

The GLIM criteria combined with the HGS test is an effective tool for diagnosing malnutrition. Particularly, these modalities are applicable in overweight colorectal cancer patients. Compared with the standard GLIM criteria, this tool has a better predictive value for postoperative complications and long-term survival.

Handgrip strength and the prognosis of patients with heart failure: A meta-analysis

BACKGROUND

Reduced muscular strength is common in patients with heart failure (HF). The aim of the systematic review and meta-analysis was to evaluate the association between handgrip strength (HGS) and prognosis of patients with HF.

HYPOTHESIS

Reduced HGS may be a risk factor of poor prognosis of patients with HF.

METHODS

Relevant observational studies with longitudinal follow-up were obtained by a comprehensive search of PubMed, Embase, Cochrane Library, and Web of Science databases. A random-effects model was used to pool the results.

RESULTS

Fifteen studies involving 7350 patients with HF were included in the meta-analysis. Pooled results showed that HF patients with lower HGS were associated with a higher risk of mortality during follow-up (risk ratio [RR]: 2.00, 95% confidence interval [CI]: 1.55-2.58, p < .001; I2  = 0%). Subgroup analysis showed that the association was not significantly affected by characteristics such as study country, design, mean age of the patients, HF status (stable or advanced/acute), HF type (reduced or preserved ejection fraction), follow-up duration, and quality score (p for subgroup difference all > 0.05). Further analysis showed that per 1 kgf decrease of HGS was associated with an 8% increased risk of mortality during follow-up (RR: 1.08, 95% CI: 1.05-1.11, p < .001; I2  = 12%). Moreover, HF patients with lower HGS were also related to a higher risk of composite outcome of HF rehospitalization or mortality (RR: 1.67, 95% CI: 1.19-2.35, p = .003; I2  = 53%).

CONCLUSION

A low HGS may be associated with poor clinical outcomes of patients with HF.
