Foot Oedema Observed Over Time Study
Heart FailureEdema LegHeart Failure is the final common pathway of most forms of cardiovascular disease. In the United Kingdom (UK), it affects around 900 000 people, causes or complicates around 5% of adult emergency hospital admissions and consumes up to 2% of total National Health Service (NHS) expenditure. An important part of discharge planning includes measures such as early follow up in order to prevent readmissions. The hallmark of heart failure is fluid retention and between 2009 and 2016, 43% to 50% of hospital admissions were associated with peripheral oedema. Therefore, early recognition of this and treatment of the congestion may prevent hospital admissions. In clinical trials, management strategies have included patient education, telemedicine and remote monitoring. The main non-invasive method for detecting fluid retention has been the use of weight as a surrogate marker. The Heartfelt device is an invention that uses a system of cameras in a compact device in order to generate 3 dimensional images of the feet and lower legs. The volumes can then be calculated and thus, changes in amount of peripheral oedema can be estimated. In a laboratory study performed by the Heart Failure team at the Royal Brompton Hospital, there was good correlation between measurements made by Heartfelt and a water displacement method. The resolution was as good as 20mls. By positioning the Heartfelt device in the bedroom, automatic measurements can be made whenever the subject gets in and out of bed. Images are only taken of the specified subject. Data is censored so that the part of the body which is 50cm above the floor is not stored. Encrypted, anonymised data is transmitted over the internet to the company's secure servers. Personal identifiable data (participant name, address, age…) is stored on an encrypted hard drive, along with linkage information (device serial numbers) to associate the participant identifiable data with the data captured in the home. Therefore, data collection is not only secure but entirely passive, which is a major advantage compared with previous non-invasive methods and it is applicable to a very wide range of compliant and non-compliant patients. Our hypothesis is that the Heartfelt device can directly detect the increase in peripheral oedema associated with heart failure decompensation and that, on average, the number of days with missing data collected by the Heartfelt device will be lower than that of the weighing scales.
Pilot Deprescribing N-of-1 Trials for Beta-blockers in HFpEF
Heart FailureHeart Failure4 moreIn this study, we will test the feasibility of N-of-1 trials for deprescribing beta-blockers in patients with Heart Failure with Preserved Ejection Fraction. To achieve this objective we will conduct 16 4-period N-of-1 trials (on vs. off) and subsequently interview participants to better understand feasibility and pragmatism. The N-of-1 trials will be iteratively refined in real-time based on this feedback.
Lancashire Objective Volume Evaluation of Leg Oedema in Heart Failure
Heart FailurePatients with heart failure (HF) who recently received treatment with IV diuretics for worsening congestion or outpatients with HF and peripheral oedema treated with at least 80 mg furosemide (or equivalent)/day will be recruited for the LOVE-HF trial at Blackpool Victoria Hospital. Eligible participants will be randomized to use the Heartfelt Device alongside standard care (weighing + symptom reporting), or standard care alone. Participants and clinicians will be blinded (double blind) as to which arm participants are in, and after 30 days, participants will be crossed over to the other arm. This can be done without disrupting patients as the Heartfelt device can be switched remotely from a 'technical checks only' mode to a 'full data analysis' mode and vice versa. The investigators aim to recruit 30 participants for the pilot study. The study will also run in parallel with its sister pilot trial, LOVE-HF-2. Through this study, we are testing the capability to get the answers from patients, healthcare systems, and devices, in order to inform future clinical trial design.
A Study to Observe Treatment Patterns in Patients in Colombia Who Have Heart Failure
Heart FailureResearchers want to learn more about the treatments doctors choose to treat heart failure. Heart failure means the heart isn't pumping as well as it should be. Heart failure can lead to other serious medical conditions, and it can lead to hospitalization or death. There are different types of treatments available for people who have heart failure, and these work in different ways. In this study, the researchers will collect information about Colombian patients who have heart failure. The main purpose of this study is to identify patterns in the treatments that doctors first prescribe to heart failure patients in Columbia. To do this, the researchers will review information from the patients' medical records and from a drug-dispensing database. The study will include adult patients who have been diagnosed with heart failure in Columbia from June 1st, 2019 to May 31st, 2020. There will be no required visits, treatments, or procedures in this study. The researchers will collect information about the treatments the patients have been prescribed by their own doctors.
Cardiac Performance in Mechanically Ventilated COVID-19 Patients
Covid19Acute Cor Pulmonale1 moreAlthough COVID-19 affects primarily the respiratory system, several studies have shown evidence of cardiovascular alterations. Increased troponin levels were observed in a significant proportion of patients and this alteration was associated with higher mortality. In addition, case reports of cardiogenic shock or fulminant myocarditis have been communicated. Likewise, pulmonary embolism (PE), right ventricle dilation, and acute cor pulmonale (ACP) have also been described. Therefore, investigating cardiac function in COVID-19 is highly relevant, particularly in critically ill patients who are usually under sedation and mechanical ventilation, which may further impair cardiovascular function. Thus the objective is to determine the prevalence of left ventricle dysfunction and acute cor pulmonale, and its association with respiratory mechanics, in 100 consecutive critically ill COVID-19 patients, who were assessed with critical care echocardiography (CCE) within the first 24 hours of mechanical ventilation.

CRTd Responders Optimization
Heart FailureHeart Failure With Reduced Ejection Fraction1 moreSuboptimal optimization of atrio-ventricular (AV) and inter-ventricular (VV) timings could affect the clinical response of CRTd in T2DM patients. Thus, authors hypothesize that automatic sensor guided CRTd optimization could ameliorate clinical outcomes in patients with T2DM. However, authors will evaluate the effects of cardiac resynchronization therapy (CRTd) in patients with type 2 diabetes mellitus (T2DM) optimized via automatic vs. echocardiographic guided approach.Authors will conduct a prospective, multicenter study to recruit, from October 2016 to June 2019, patients with T2DM and heart failure (HF) candidate to receive a CRTd. After CRTd the patients will be optimized via automatic vs. echocardiographic guided approach.
Implementation of the Hospital to Home (H2H) Heart Failure Initiative
Heart FailureThis study determines if a community of practice of clinicians and quality improvement specialists can be used to implement a national quality initiative known as Hospital to Home (H2H). This quality initative is designed to reduced readmission rates for patients with heart failure or heart attack by improving the transition of care upon discharge.
