Food As Medicine for Heart Failure

Malnutrition and unintentional weight loss are highly prevalent among patients with heart failure (HF), with approximately 50% of patients with heart failure meeting malnutrition criteria. Poor dietary quality and micronutrient deficiencies are associated with higher rates of HF hospitalization and mortality. Therefore nutritional interventions to improve dietary quality and prevent malnutrition development may represent an effective strategy to improve HF-related health status and survival outcomes. To date, there are no large clinical trials investigating the efficacy of 'food as medicine' to improve morbidity and mortality for patients with heart failure with reduced ejection fraction (HFrEF). The investigators plan to conduct a single-center, randomized pilot trial to assess the tolerability, feasibility, and efficacy of providing medically-tailored meals (MTMs) to patients with HFrEF and malnutrition. The investigators hypothesize that home delivery of MTMs will be feasible, well-tolerated and achieve a high degree of satisfaction for patients with HFrEF. The proposed pilot study is a randomized crossover trial, in which each subject receives a 12-week standard of care phase with self-directed dietary intake and a 12-week MTM dietary intervention phase, with a 4-week washout period between the two phases. Meals will be designed, prepared and delivered by our community based organized partner, Community Servings. The investigators will measure HF-related health status, functional capacity, and biomarkers of heart failure and nutritional status before and after each study phase. The proposed study will facilitate a larger future randomized trial of MTM for patients with HFrEF and malnutrition, powered to examine the impact on HF hospitalizations and mortality.

Evaluation of the Program to Help Return Home Patients Hospitalized for Heart Failure, From Paris Saint-Joseph Hospital

The prevalence of heart failure is very high worldwide is between 1 and 2% in developed countries. The French Federation of Cardiology estimates that a million people are affected in France. Each year in France, there are nearly 70,000 deaths linked to heart failure, and more than 150,000 hospitalizations with an average cumulative duration per year of 12.7 days, figures which show the extent of the phenomenon. Heart failure is therefore a common pathology, which constitutes an important public health issue. It requires rigorous monitoring and early adaptation of treatments to avoid repeated hospitalizations. Studies show that following hospitalization for heart failure, all-cause re-hospitalization rates rise to 18% within 30 days. In 2019, the rate of re-hospitalization at 1 year is 30%, half of which in the following 3 months. The prognosis is grim with 20 to 30% of deaths within the year. The European Society of Cardiology recommends that the patient be integrated into a care path coordinated by the general practitioner; and a consultation with his general practitioner in the week after hospitalization and his cardiologist within two weeks. The CPAM (Caisse Primaire d'Assurance Maladie) has set up since 2013 the PRADO-IC program (Program for Return to Home Hospital for Heart Failure). This program must be in place before discharge from hospital. A health insurance advisor comes to meet the patient, declared eligible for PRADO by the hospital medical team, to present the offer and collect his approval before discharge. He then contacts the attending physician and organizes his return home. A follow-up book is given to the patient to allow better transmission of information between town and hospital. A specially trained nurse visits the patient's home every week. The duration of PRADO support varies according to the NYHA stage of severity. It provides therapeutic education with reinforcement of hygieno-dietetic rules, warning signs, checks compliance with treatments and the necessary biological monitoring and must alert the attending physician in the event of aggravation. The objectives of this program are: to preserve the quality of life and the autonomy of patients, to support the reduction of the length of stay in hospital, to strengthen the quality of care in town around the attending physician, improve the efficiency of recourse to hospitalization by reserving the heaviest structures for the patients who need them most.

Mechanisms Underlying Hypotensive Response to ARB/NEP Inhibition - Aim 2

LCZ696, a molecular complex of the angiotensin receptor blocker (ARB) valsartan with an inhibitor of neprilysin (NEP, neutral endopeptidase-24.11) sacubitril improved mortality compared to enalapril in patients with heart failure (HF), reduced ejection fraction (EF), and increased brain natriuretic peptide (BNP) or N-terminal pro-BNP (NT-proBNP) in the PARADIGM-HF trial.1 The PIONEER-HF study demonstrated the efficacy of LCZ696 in preventing rehospitalization in patients with acutely decompensated HF.2 LCZ696 has been underutilized in heart failure, in part due to concerns about hypotension. NEP degrades several vasodilator peptides including bradykinin, substance P and brain-type natriuretic peptide. Decreased degradation of endogenous bradykinin could contribute to hypotension at initiation of LCZ696 through vasodilation or through increased natriuresis and diuresis. Inhibition of the bradykinin B2 receptor using icatibant would be expected to prevent this effect. Objectives The main objectives of this mechanistic randomized, double-blind, crossover-design study are: The primary objective is to test the hypothesis that endogenous bradykinin contributes to effects of ARB/NEP inhibition on blood pressure, natriuresis, and diuresis at initiation. The secondary objective is to test the hypothesis endogenous bradykinin contributes to effects of ARB/NEP inhibition on blood pressure, natriuresis, and diuresis after up-titration. Eighty (80) subjects with stable heart failure who meet all inclusion/exclusion criteria will be enrolled. Subjects who qualify will collect their urine for 24 hours before each study day for measurement of volume, sodium and potassium. At the start of the study, they will stop their regular angiotensin-converting enzyme (ACE) inhibitor or ARB. After a 48-hour washout, they will undergo a study day in which they are given a single dose of 50 mg LCZ696. They will also receive either the bradykinin B2 receptor antagonist icatibant or placebo vehicle in random order (double-blind). After a 96-hour washout, they will repeat the study day and receive a single dose of 50 mg LCZ696 and the opposite study drug (icatibant or placebo). After completion of the two acute study days, subjects will take LCZ696 50 mg bid for two weeks, followed by LCZ696 100 mg bid for three weeks, and then LCZ696 200 mg bid, following the conservative up-titration protocol from the TITRATION study.3 Criteria for continuing up-titration appear in the full study protocol. On the 7th and 10th day of the 200 mg bid or highest tolerated dose, subjects will again undergo two more study days three days apart in which they are randomized to receive either icatibant or vehicle.

Evaluation of the Benefit of Traditional Karate in Heart Failure for Cardiac Rehabilitation

Cardiac rehabilitation is based on physical activity which, usually, associates combination of a cycle ergometer or treadmill completed by gymnastics. Some studies have been done with complementary physical activities such as tai chi or yoga integrated into the strategy of non-drug therapies. The tai chi study showed a tendency to improve the peak of VO2 in the tai chi group but which was not significant but also a significant improvement on secondary objectives such as quality of life, the increase in the 6-minute walk test and a decrease in the level of natriuretic peptides. A study of the effects of yoga after coronary artery bypass surgery showed at one year an improvement of the ejection fraction, the lipid profile and the state of anxiety of the patients. This study showed that the addition of yoga to conventional cardiac rehabilitation could improve cardiovascular risk factors especially in patients with abnormalities such as low HDL. The physical activities offered in rehabilitation to improve physical performance are currently limited to cycling, treadmill or gymnastics. Many patients do not like cycling or treadmill, which limits their adherence to a cardiac rehabilitation program. Moreover, one of the main problems of rehabilitation is that after the rehabilitation cycle, a minority of patients continue the physical activity. Strategies for implementing home exercises have been tested to increase the level of physical activity after rehabilitation. Cardiac rehabilitation has several components: correction of risk factors, optimization of treatment, physical activity to improve the physical abilities to exertion that are directly correlated to mortality. Our hypothesis is that the implementation of a program of physical activity based on traditional karate would improve the physical abilities to effort and the quality of life of patients, to give a better psychological confidence to patients who, after a cardiovascular event such as acute coronary syndrome, bypass surgery or valvular surgery, have marked anxiety or depression. Rehabilitation, and especially physical activity, is one of the therapeutic means proposed. The interest of this study would be to be able to offer an additional activity for rehabilitation centers, to offer patients an activity in post-rehabilitation. In addition, interaction between patients could increase adherence to rehabilitation.

Brazilian Heart Insufficiency With Telemedicine

A collaboration gap across sectors is a common problem in Denmark and Brazil. Brazilian Heart Insufficiency with Telemedicine (BRAHIT) will run in parallel with the ongoing Danish Reaching the Frail Elderly project (REAFEL - NCT04162548), supported by the Ministry of Higher Education and Health (Innovationsfonden - Grand Solutions), until 2021. REAFEL seeks a stronger collaboration between primary care and hospital cardiologists to manage frail elderly patients, using teleconsultation and data from mobile devices in Denmark. Health resources are scarce in Brazil and a pressing need for the Municipal Secretary of Health of Rio de Janeiro is to reduce wait times to access some areas, as cardiology. When patients are stable after undergoing highly complex procedures in a tertiary hospital, are discharged to outpatient treatment at primary care but, a heterogenous expansion of the primary care system in the Rio de Janeiro municipality has created a great resistance from the population, and among cardiologists, to accept continuing cardiology treatment at the primary care system. Enhancing a collaboration between primary care and cardiologists, that is tangible for the patients, can relieve this pressure. The cross-sectorial collaboration in BRAHIT is based on the involvement of Instituto Nacional de Cardiologia (INC), a tertiary cardiology hospital, with primary investigator Aurora Issa (INC) and primary-and homecare in Rio de Janeiro, with primary investigator Leonardo Graever, Primary Care Special Advisor in the Municipality of Rio de Janeiro. The project proposal originates from Denmark and sponsors the project through a Danida grant (Window 2 from the Danish Foreign Ministry - Danida Fellowship Center 18-M03-KU) to the cardiologist Helena Domínguez, as associate professor in the Dept. of Biomedicine, UCPH, and consultant in Bispebjerg-Frederiksberg Hospital. Being complex public health intervention studies, mixed methods are necessary to evaluate the value gained in the project and to provide research-based policy briefs. The methods include qualitative analyses and a cluster-randomization trial, the latter used for power calculation. Such calculation is based on adequate heart failure medications aggregated in a score constructed for this purpose. Secondary end-point is rate of number of readmissions for any cause, after discharge with heart failure diagnosis.
