The effect of exercise training and physiotherapy on left and right heart function in heart failure with preserved ejection fraction: a systematic literature review.

The impact of exercise training and physiotherapy on heart function and pulmonary circulation parameters in heart failure with preserved ejection fraction (HFpEF) patients is uncertain. Hence, we performed a systematic review of published trials studying physical training in HFpEF population, with a focus on exercise and physiotherapy effect on left ventricular (LV), right ventricular (RV) morphological, functional, and pulmonary circulation parameters. We searched Cochrane Library and MEDLINE/PubMed for trials that evaluated the effect of exercise training and/or physiotherapy in adult HFpEF patients (defined as LVEF ≥ 45%), including publications until March 2021. Our systematic review identified eighteen articles (n = 418 trained subjects, 4 to 52 weeks of training) and covered heterogeneous trials with various populations, designs, methodologies, and interventions. Five of twelve trials revealed a significant reduction of mitral E/e' ratio after the training (- 1.2 to - 4.9). Seven studies examined left atrial volume index; three of them showed its decrease (- 3.7 to - 8 ml/m2). Findings were inconsistent regarding improvement of cardiac output, E/A ratio, and E wave DecT and uncertain for RV function and pulmonary hypertension parameters. For now, no reliable evidence about rehabilitation effect on HFpEF cardiac mechanisms is available. There are some hypotheses generating findings on potential positive effects to parameters of LV filling pressure (E/e'), left atrium size, cardiac output, and RV function. This encourages a broader and more complex assessment of parameters reflecting cardiac function in future HFpEF exercise training studies.

Effect of home-based prehabilitation on postoperative complications after surgery for gastric cancer: randomized clinical trial.

BACKGROUND: Recent studies have demonstrated that prehabilitation improves patients' physical fitness but its impact on postoperative morbidity remains unclear. This study aimed to assess the effect of personalized, multimodal, semisupervised, home-based prehabilitation on postoperative complications after surgery for gastric cancer. METHODS: This RCT was conducted at two centres in Lithuania. Patients (aged at least18 years) with gastric cancer scheduled to undergo elective primary surgery or surgery after neoadjuvant chemotherapy for gastric cancer were randomized (1 : 1) to prehabilitation or standard care. Prehabilitation included exercise interventions focused on endurance, respiratory muscle strength, stretching, and resistance training as well as nutritional and psychological support. The primary outcome was the proportion of patients with postoperative complications within 90 days after surgery. Secondary outcomes included 90-day mortality rate, physical condition, fitness level, nutritional status, quality of life, anxiety and depression level, and proportion of patients completing neoadjuvant chemotherapy. RESULTS: Between February 2020 and September 2022, 128 participants were randomized to prehabilitation (64) or standard care (64), and 122 (prehabilitation 61, control 61) were analysed. The prehabilitation group had increased physical capacity before the operation compared with baseline (mean 6-min walk test change +31 (95 per cent c.i. 14 to 48) m; P = 0.001). The prehabilitation group had a decreased rate of non-compliance with neoadjuvant treatment (risk ratio (RR) 0.20, 95 per cent c.i. 0.20 to 0.56), a 60 per cent reduction in the number of patients with postoperative complications at 90 days after surgery (RR 0.40, 0.24 to 0.66), and improved quality of life compared with the control group. CONCLUSION: Prehabilitation reduced morbidity in patients who underwent gastrectomy for gastric cancer. REGISTRATION NUMBER: NCT04223401 (http://www.clinicaltrials.gov).

The Experience, Prerequisites, and the Barriers in Organizing a Specialized Rehabilitation Program for Patients with Pulmonary Hypertension.

BACKGROUND: Pulmonary hypertension (PH) is a severe progressive disease, associated with reduced exercise capacity and poor quality of life. Although scientific evidence supports the incorporation of specialized training in the treatment of PH, it is only available in a few countries. OBJECTIVES AND METHODS: This article aims to share the experience of implementing a PH rehabilitation program, to summarize the barriers and prerequisites for launching this service, and to assess its early effect. We retrospectively analyzed our pathway in organizing this program, by singling out essential steps. RESULTS: The preparation phase took about 14 months. Establishing and running of a PH rehabilitation program required dedicated rehabilitation specialists to join the multidisciplinary PH expert team. Team members needed to gain special knowledge on exercise training in severely compromised patients; thus, supervision and education by experienced consultants was crucial. The main eligibility criteria for patients were stable status, optimal medical treatment, and motivation to undergo the training. The first results evaluating the effect of a specialized PH training program in 9 patients are promising. Seven of them improved their functional capacity over the period of 15 weeks. CONCLUSIONS: Despite a number of challenges and barriers, the implementation of a specialized rehabilitation program should be encouraged in a few dedicated PH expert centers per country, who are capable to fulfill all prerequisites and organizational aspects. Local PH experts, supervision by an experienced center, in-patient rehabilitation facilities, dedicated personnel, equipment, and patient motivation are essential.

Safety and effectiveness of standardized exercise training in patients with pulmonary hypertension associated with heart failure with preserved ejection fraction (TRAIN-HFpEF-PH): study protocol for a randomized controlled multicenter trial.

BACKGROUND: Left heart failure (HF) is characterized by an elevation in left-sided filling pressures, causing symptoms of dyspnea, impairing exercise capacity, and leading to pulmonary venous congestion and secondary pulmonary hypertension (PH). There is an increased incidence of PH associated with left heart disease, particularly with heart failure with preserved ejection fraction (HFpEF-PH). Treatment possibilities in HFpEF-PH are non-specific and very limited, thus additional pharmacological and non-pharmacological therapeutic strategies are needed. Various types of exercise-based rehabilitation programs have been shown to improve exercise capacity and quality of life (QoL) of HF and PH patients. However, no study focused on exercise training in the population of HFpEF-PH. This study is designed to investigate whether a standardized low-intensity exercise and respiratory training program is safe and may improve exercise capacity, QoL, hemodynamics, diastolic function, and biomarkers in patients with HFpEF-PH. METHODS: A total of 90 stable patients with HFpEF-PH (World Health Organization functional class II-IV) will be randomized (1:1) to receive a 15-week specialized low-intensity rehabilitation program, including exercise and respiratory therapy and mental gait training, with an in-hospital start, or standard care alone. The primary endpoint of the study is a change in 6-min walk test distance; secondary endpoints are changes in peak exercise oxygen uptake, QoL, echocardiographic parameters, prognostic biomarkers, and safety parameters. DISCUSSION: To date, no study has investigated the safety and efficacy of exercising specifically in the HFpEF-PH population. We believe that a randomized controlled multicenter trial, which protocol we are sharing in this article, will add important knowledge about the potential utility of a specialized low-intensity exercise and respiratory training program for HFpEF-PH and will be valuable in finding optimal treatment strategies for these patients.

Biologically Active Adrenomedullin (bio-ADM) is of Potential Value in Identifying Congestion and Selecting Patients for Neurohormonal Blockade in Acute Dyspnea.

PURPOSE: This study was designed to evaluate the role of biologically active adrenomedullin (bio-ADM) in congestion assessment and risk stratification in acute dyspnea. METHODS: This is a sub-analysis of the Lithuanian Echocardiography Study of Dyspnea in Acute Settings. Congestion was assessed by means of clinical (peripheral edema, rales) and sonographic (estimated right atrial pressure) parameters. Ninety-day mortality was chosen for outcome analysis. RESULTS: There were 1188 patients included. Bio-ADM concentration was higher in patients with peripheral edema at admission (48.2 [28.2-92.6] vs 35.4 [20.9-59.2] ng/L, P < .001). There was a stepwise increase in bio-ADM concentration with increasing prevalence of rales: 29.8 [18.8-51.1], 38.5 [27.5-67.1], and 51.1 [33.1-103.2] ng/L in patients with no rales, rales covering less than one-half, and greater than or equal to one-half of the pulmonary area, respectively (P < 0.001). Bio-ADM concentration demonstrated gradual elevation in patients with normal, moderately, and severely increased estimated right atrial pressure: 25.1 [17.6-42.4] ng/L, 36.1 [23.1-50.2], and 47.1 [30.7-86.7] ng/L, respectively (P < .05). Patients with bio-ADM concentration >35.5 ng/L were at more than twofold increased risk of dying (P < .001). Survival in those with high bio-ADM was significantly modified by neurohormonal blockade at admission (P < .05), especially if NT-proBNP levels were lower than the median (P = .002 for interaction). CONCLUSION: Bio-ADM reflects the presence and the degree of pulmonary, peripheral, and intravascular volume overload and is strongly related to 90-day mortality in acute dyspnea. Patients with high bio-ADM levels demonstrated survival benefit from neurohormonal blockade.

The dynamics of self-care in the course of heart failure management: data from the IN TOUCH study.

INTRODUCTION: Self-care is an important patient-reported outcome (PRO) for heart failure (HF) patients, which might be affected by disease management and/or telemonitoring (TM). The number of studies reporting the influence of TM on self-care is limited. AIMS: This study aimed: to assess whether TM, in addition to information-and-communication-technology (ICT)-guided disease management system (ICT-guided DMS), affects self-care behavior; to evaluate the dynamics of self-care during the study; to investigate factors contributing to self-care changes; and to identify a patient profile that predisposes the patient to improvement in self-care. METHODS: In the INnovative ICT-guided-DMS combined with Telemonitoring in OUtpatient clinics for Chronic HF patients (IN TOUCH) study, 177 patients were randomized to either ICT-guided DMS or TM+ICT-guided DMS, with a follow-up of 9 months. The current analysis included 118 participants (mean age: 69±11.5 years; 70% male) who filled the following PRO instruments: the nine-item European Heart Failure Self-care Behaviour scale (EHFScBs), Hospital Anxiety and Depression scale (HADs), and Minnesota Living with HF Questionnaire (MLHFQ). RESULTS: The baseline level of self-care was better in the TM+ICT-guided-DMS group (n=58) compared to ICT-guided-DMS group (n=60, p=0.023). Self-care behavior improved in the ICT-guided-DMS group (p<0.01) but not in the TM+ICT-guided-DMS group. Factors associated with self-care worsening were as follows: higher physical subscale of MLHFQ (per 10 points, p<0.05), lower left ventricular ejection fraction (LVEF) (per 5%, p<0.05), lower New York Heart Association (NYHA) class (class III vs class II, p<0.05). The subgroups of patients who had an initial EHFScBs total score >28, or from 17 to 28 with concomitant HADs depression subscale (HADs_D) score ≤8, demonstrated the greatest potential to improve self-care during the study. CONCLUSION: TM did not have an advantage on self-care improvement. Poor physical aspect of quality of life, lower LVEF, and lower NYHA class were associated with self-care worsening. The greatest self-care improvement may be achieved in those patients who have low or medium initial self-care level in the absence of depression.
