The Effects of Exercise-Based Interventions on Fluid Overload Symptoms in Patients with Heart Failure: A Systematic Review and Meta-Analysis

Predictors of the Efficacy of Lymphedema Decongestive Therapy

Lymphedema is a chronic condition characterized by the accumulation of lymphatic fluid in the tissues, causing swelling primarily in the limbs, though other body parts can also be affected. It commonly develops after lymph node removal, or radiation therapy, or due to congenital lymphatic system defects. Effective management is essential due to its significant impact on physical function and quality of life. Complete Decongestive Therapy (CDT) is the primary treatment for lymphedema. This comprehensive approach combines manual lymphatic drainage (MLD), compression bandaging, skincare, and exercise. An early diagnosis and initiation of CDT are critical to preventing irreversible damage to the lymphatic system and worsening symptoms. Successful outcomes depend on timely treatment, patient adherence, and the consistent use of all CDT components, with compression therapy and exercise playing particularly vital roles. Recent research highlights how skin and fat tissue characteristics, such as increased skin thickness and adipose tissue accumulation, complicate lymphedema management, especially in advanced stages. In these cases, where fibrosis and fat deposition are more prominent, traditional CDT may need to be supplemented with advanced treatments like liposuction or enhanced compression techniques. This study explores the factors influencing the success of decongestive therapy, including the stage of lymphedema at the diagnosis, treatment protocols, and individual patient characteristics like skin and fat tissue properties.

Sociodemographic characteristics, lifestyle behaviors, and symptoms associated with fluid overload among non-hospitalized and community-dwelling older adults with heart failure: A population-based approach

BACKGROUND

Fluid overload is a major complication in patients with heart failure (HF) and the main reason for hospitalization. The purpose of the study was to explore the associations of fluid overload with sociodemographic characteristics, lifestyle behaviors, and symptoms among non-hospitalized and community-dwelling older adults with HF using large population data.

METHODS

Descriptive and multivariate analyses were conducted on the Health and Retirement Study 2016.

RESULTS

Fluid overload was prevalent in almost half of the sample. Female older adults with HF were more likely to have fluid overload (OR:1.43, p = 0.037) as well as being Black (OR:1.40, p = 0.041). Higher physical activity scores were associated with less likelihood of having fluid overload (OR:0.99, p = 0.025). Symptoms of shortness of breath (OR=2.18, p = 0.001), pain (OR=1.82, p < 0.001), and fatigue (OR=1.45, p = 0.025) were significantly associated with fluid overload.

CONCLUSION

Female and Black community-dwelling older adults with HF are at higher risk of fluid overload. Symptoms of shortness of breath, pain, and fatigue are significant manifestations of fluid overload. Effective patient-centered interventions to promote fluid flow via physical activity may help older adults with HF manage fluid overload and alleviate associated symptoms.

Exercises in activating lymphatic system on fluid overload symptoms, abnormal weight gains, and physical functions among patients with heart failure: A randomized controlled trial

Background

Fluid overload remains a vexing problem in management of heart failure. The lymphatic system that plays the central role in fluid homeostasis has recently been explored as a potential target to counteract tissue fluid overload. The goal of the study was to evaluate the preliminary effects of exercises in activating lymphatic system on fluid overload symptoms, abnormal weight gains, and physical functions for patients with heart failure.

Methods and results

A pilot, pre- and post-test, randomized clinical trial was conducted to recruit a total of 66 patients who were randomized to receive either a 4-week The-Optimal-Lymph-Flow for Heart Failure (TOLF-HF) program or usual care alone. The primary outcome was the prevalence and burden of the fluid overload symptoms. Findings of the trial showed that the TOLF-HF intervention was effective in reducing the prevalence or burden of the majority of fluid overload symptoms. TOLF-HF intervention also demonstrated significant improvement in the outcomes of abnormal weight gains (MD: -0.82; 95% CI: -1.43 to -0.21; P = 0.010) and physical functions (F = 13.792, P < 0.001).

Conclusions

The TOLF-HF program focusing on activating lymphatic system through the performance of therapeutic lymphatic exercises holds the promise as an adjuvant therapy for patients with heart failure to manage fluid overload symptoms, reduce abnormal weight gains, and improve physical functions. Future larger-scale study with longer duration of follow-up is needed.
