Active clinical trials for "Heart Failure"

The purpose of this study is to determine whether an early goal-directed decrement of preload and afterload with a target systolic blood pressure of 90-110 mmHg by aggressive vasodilatation in patients with acute HF in the non-ICU setting is safe, and leads to a better clinical and economical outcome

The objective of the B-Convinced study is to demonstrate the non-inferiority of beta-blocker continuation compared to its interruption in patients with congestive heart failure who are treated by a beta-blocker and present with an episode of heart failure worsening with pulmonary oedema requiring hospital admission. 162 patients will be randomized in cardiology centers in France. Clinical status (primary endpoint) will be evaluated with a standardized questionnaire 3 days after hospital admission.

The human heart is divided into four chambers. One of the four chambers, the left ventricle, is the chamber mainly responsible for pumping blood out of the heart into the circulation. Diseases of the heart like congestive heart failure (CHF), can cause the left ventricle to function improperly. Medications called beta-blockers appear to reverse the abnormalities in the left ventricle and frequently improve the function of the left ventricle in patients with different kinds of heart disease. How beta-blockers improve left ventricle function is unknown. One possible reason for improved function of the left ventricle with beta-blockers is improved blood flow to the heart muscle. When a region of the heart is active, it uses more fuel in the form of oxygen and sugar (glucose). As heart activity increases, blood flow to and from the area of activity increases also. Knowing these facts, researchers can use radioactive sugar (glucose) and positron emission tomography (PET) scans to observe what areas of the heart are receiving more blood flow. In this study researchers plan to measure glucose use in heart muscle and blood flow to the heart muscle in patients with CHF taking beta-blockers.

The Multi-Ethnic Study of Atherosclerosis (MESA) was initiated to study the correlates, predictors, and progression of subclinical cardiovascular disease (CVD) (disease detected non-invasively before it has produced clinical signs and symptoms) in a diverse population-based sample of men and women aged 45-84 who had no evidence of clinical CVD at baseline (www.mesa-nhlbi.org). During 2000-2002, 6,814 participants were recruited from six field centers (Forsyth County, NC; Northern Manhattan and the Bronx, NY; Baltimore City and Baltimore County, MD; St. Paul, MN; Chicago, IL; and Los Angeles County, CA). The ethnic composition of the recruited cohort was 38% Caucasian, 28% African American, 22% Hispanic, and 12% Chinese. An extensive baseline exam focused on critical CVD risk factors and subclinical disease measures. Five subsequent exams took place through 2018 to assess changes in these measures and to explore new innovative research questions. Cohort members are contacted annually to obtain information about intervening hospitalizations and outpatient cardiovascular-related procedures. Relevant medical records are abstracted and reviewed and clinical endpoints of interest are adjudicated. The study is comprised of one Coordinating Center, six Field Centers and one biospecimen repository.

Collect data on Mexican patients diagnosed with Heart Failure with reduced ejection fraction, their treatments, and their progress in a real-world environment. Additional objectives will be analyzed, such as mortality, the use of resources associated with the follow-up of this group of patients and the barriers, if any, to receiving the indicated treatment.

The study will test the ability a novel wearable sensor based on a smartphone app (Precordior CardioSignal app) in combination with a sensor device (Suunto Movesense sensor) to non-invasively measure cardiac motion and function.

The prevalence of Heart failure above 70 years of age is 10% and 5 year mortality rate above 60%, higher than for cancer. The readmission rate first after hospitalisation is 44% despite the availability of life prolonging and life quality enhancing treatment. There is a lack of resources for adequate diagnostic workup necessary for implementing evidence-based treatment. This projects aims at assessing the impact of guidelines based diagnostic workup and guidelines based treatment of heart failure on mortality and readmission rates. As the symptoms defining the degree of heart failure and the discharge medication only is available in the electronic patient files, artificial intelligence is used to retrieve this information to assess if treatment is according to guidelines. The project is using first a rule based text processing approach using IBM Watson, then advancing to a machine learning approach using readmission and mortality as endpoints. The project has access to digitally stored echocardiographic measurements as well as digital ECG's and lab data on 15 000 patients admitted with a diagnosis of Heart failure. If the retrieval of symptoms and function by artificial intelligence is successful, the next step is to assess if those benefitting the most from echocardiography can be identified using information from the ECG's, lab data or symptoms and functional capacity as described in the Electronic Health Records.

The purpose of this study is to investigate continuous 8-hour introductions of BMS-986231 in participants with heart failure and weakened heart function given a standard dose of diuretic.

The research project aims to perform data extraction, integration and analysis across multiple clinical, administrative, financial and pharmacy databases in the participating institutions. The key data components will include clinical cardiovascular specific data, procedural data, financial and administrative data (e.g. cost of medications and supplies, length of stay, diagnosis codes etc.), short-to-long term clinical outcomes (including hospital re-admissions, cardiovascular events, death), and quality-of-care indices (e.g. compliance to guideline-recommended therapy and medications). The research project will involve all patients proven and/or suspected with coronary artery disease (CAD), congestive heart failure (CHF) and atrial fibrillation (AF) admitted to National Heart Centre Singapore (NHCS) and NUH.

Patients with heart failure and preserved left ventricular ejection fraction (HFpEF, EF ≥ 50%) or mid-range left ventricular ejection fraction (HFmrEF, 40% < EF < 50%) with mild to moderate functional limitation will be evaluated for treatment via creation of a no-implant interatrial shunt using clinical, echocardiographic, and invasive hemodynamic data.
