Active clinical trials for "Heart Failure"

The purpose of this study is to determine if certain findings (blood tests, symptom improvement, etc.) after acute heart failure treatment can identify a group of patients who are safe for early hospital discharge.

The purpose of this study is to determine whether discussions of life story, forgiveness, and future goals improve quality of life for patients with serious illness.

Monocyte tissue factor (TF) was characterized in Class C heart failure (HF) vs. 25 age-matched volunteers. TF was 2.9 fold higher (p < 0.001) in HF patients vs. controls. HF patients showed increased clinical events (RR=1.29, p=0.04) when comparing procoagulant activity above/below median. HF is associated with increased TF expression.

We, the researchers, propose to link a clinical pharmacist with an internal medicine or family medicine team to provide pharmaceutical care to all patients assigned to the team. The hypothesis is that through this team based approach, pharmacists will act as a resource for providing pharmacotherapeutic advice during the drug therapy decision making process and promote optimal drug use by identifying and resolving actual and potential drug related problems. This study is designed to test this hypothesis, by assessing the impact of this intervention on evidence based, quality of drug therapy indicators, for patients admitted with heart failure (HF), chronic obstructive pulmonary disease (COPD), community acquired pneumonia (CAP), type 2 diabetes mellitus (T2DM), and stable coronary artery disease (CAD).

To explore the role of insulin growth factor in cardiovascular disease in older men and women.

Discharge to the community is increasingly becoming a priority for patients implanted with a Ventricular Assist Device (VAD). Because VADs are complex, patients and caregivers often fear leaving the hospital, although their status does not require hospitalization. This project includes development of CD/video and web-based instructional programs on management of the VAD controller for patients and their caregivers (formal and informal). A clinical trial will be used to examine discharge rates and placements following patients educated under usual care vs. self-pace CD/video conditions.

Research question: What is the response of the heart's pumping function to changes in heart chamber pressures? Experimental design: Patients undergoing routine cardiac catheterization will be studied. A thermodilution pulmonary artery catheter will be inserted through a venous sheath and threaded into the pulmonary artery. After several minutes of quiet rest, baseline hemodynamics will be obtained, including a determination of cardiac output using thermodilution techniques and 30 seconds of pressure recordings from the left ventricle and proximal aorta. In addition, a brief echocardiogram will be performed, to determine ejection fraction and indices of diastolic filling. Finally, arterial tonometry will be obtained in quick succession from the brachial, radial, femoral, and carotid arteries. Following the collection of baseline data, a bolus and infusion of nesiritide will be started. After 10 minutes of nesiritide infusion, with the drug still infusing, a full set of invasive hemodynamics will again be obtained, as well as brief echocardiographic and arterial tonometry examinations.

The American Heart Association announces that exercise training should be considered for all stable cardiac patients (Class I, Level A). Therefore, exercise is an important issue for cardiac patients. It has also been reported that high-intensity interval training (HIIT) brings benefits on reversal of cardiac remodeling and long-term survival for HF patients. This study explores high-intensity interval training (HIIT) effects on long-term survivals in heart failure (HF) patients, diagnosed according to the Framingham criteria. This retrospective cohort study is going to analyze HF patients diagnosed between January 1, 2009 and May 31, 2022 in a tertiary care hospital. All HF patients underwent the multidisciplinary disease management program (MDP) in the hospital were initially surveyed. Participants were further categorized into HF with reduced ejection fraction (HFrEF) (left ventricle ejection fraction [LVEF]<40%), HF with mildly reduced EF (HFmrEF) (LVEF>=40% and LVEF< 50%), and HF with preserved EF (HFpEF) ( LVEF>=50%) based on the initial 2-D echocardiography. Participants will be further divided into HIIT+MDP or MDP only in each group based on patient preference. Age, sex, body height, body weight, disease duration, etiology for HF, co-morbidities, and medication were documented during follow-up (F/U). B-type natriuretic peptide, natriuretic peptide (BNP), cardiopulmonary exercise test (CPET) for peak oxygen consumption (VO2peak) and 2-D echocardiography for LV geometry were repeatedly assessed during follow-up. The end-point is the death of the patients or the date of May 31, 2022. All mortality causes and overall survival rates will be determined at the end of F/U. HIIT effects on long-term survival (Kaplan-Meier survival curve) for patients with different heart failure phenotypes will be estimated by log rank test. Continuous variables between different groups were analyzed by student t-test, while continuous variables before and after HIIT within groups were assessed by paired t-test. Other non-continuous variables such as sex, and co-morbidities were compared by chi-square test.

A prospective, single centre, observational cohort study at University Hospital Southampton NHS Foundation Trust of 50 consecutive patients with Heart Failure with reduced Ejection Fraction and Ejection Fraction ≤35% who are eligible for sacubitril/valsartan (Entresto) initiation as per European Society of Cardiology guidelines. Participants will have baseline and repeat cardiac magnetic resonance imaging (CMR) scans after 4-6 months of Entresto therapy. The CMR scans will be compared. Clinical outcomes at 6 months including combined outcome of death and/or heart failure hospitalisation, KCCQ-12 questionnaire, 6-minute walk test, routine blood tests and NTproBNP will also be described. This study will be the first to examine the effects of sacubitril/valsartan (Entresto) therapy on left ventricular reverse remodelling in patients with symptomatic HFrEF as demonstrated by Cardiac Magnetic Resonance Imaging.

The AWARENESS HF-PD is a cross-sectional, multicenter, survey-based study. Cases who were admitted to the outpatient clinic and hospitalized with the diagnosis of Heart Failure (Acute and Chronic) will be included in the study.
