Filter by:This is a Phase I, Multicentre study to Compare the Effect of AZD9977 and Spironolactone on Serum Potassium [sK+] during 28 days in Patients with HFmrEF or HFpEF and eGFR in the range of ≥40 and ≤70 mL/min/1.73m2.
Cardiac failure (HF) and type 2 diabetes mellitus (T2DM) are two clinical conditions with a significant impact on public health worldwide. In the elderly population the prevalence of T2DM is constantly increasing as well as its incidence in all Western countries including Italy. The combination of HF and T2DM is frequent and leads to an increased risk of death and of non-fatal adverse cardiovascular (CV) events which justifies the frailty of this population. Although diabetic patients (pts) with HF respond to recommended treatments for HF, the effective and safe control of blood glucose levels is still an outstanding clinical problem, since glucose lowering drugs may increase the risk of CV adverse events. Insulin, used in about 30% of diabetic patients with HF, causes adverse effects such as fluid and sodium retention and unwanted effects of hypoglycemia. Even if insulin remains a milestone in glucose lowering therapy of T2DM, its risk/benefit ratio is still controversial, more so when given to old patients with HF. The issue has gained relevance since new antidiabetic agents, as the sodium glucose co-transporter 2 (SGLT- 2) inhibitors and glucagon-like peptide (GLP-1) analogues, with a safer CV profile have been made available. While the transferability of the CV benefits attributed to the new drugs needs to be assessed in clinical practice, the present study explore the benefit/risk profile of insulin in HF. Objectives: to assess comparatively in patients with heart failure and T2DM the benefit/risk profile over 1-year follow-up of two antidiabetic strategies, standard care with vs without insulin in terms of humoral and clinical endpoints including body weight change, all-cause mortality and burden of care components (hospitalizations for CV events and episodes of severe hypoglycemia).
The purpose of this project is to quantify normal and abnormal skin blood flow regionally in different areas of the body(face, extremities, over burns and wounds) at baseline and over time in response to treatment or environmental changes, such as temperature, light and pressure.
This is an observational, prospective, single arm, multi-center registry to evaluate the Cordella™ Heart Failure System (CHFS) in up to 250 NYHA Class III HF patients .
A prospective, multi-national, open-label clinical study which is conducted to asses the safety, feasibility and performance of the TRVD™ System in hospital-admitted patients with Acute Decompensated Heart Failure (ADHF) and evidence of reduced left ventricular ejection fraction. The study will include patients who present with significant venous congestion, as evidenced by clinical, laboratory and imaging signs of fluid retention. Study participation, for each enrolled subject, will last approximately 3 months post index procedure. Patients will be evaluated from enrollment until hospital discharge, then at 30, 60, and 90 days post procedure.
In the U.S., 5.7 million people have heart failure (HF), 915,000 new cases are diagnosed each year, and both incidence and prevalence are increasing due to the aging of the population and to better survival from ischemic heart disease. A hallmark of HF, is poor functional status that, characteristically, deteriorates as the condition progresses, negatively affecting patients' quality of life. Poor functional status is associated with increased risk of hospitalization for exacerbations of HF and with increased mortality. Optimization of drug therapy and appropriate use of resynchronization therapy can improve functional status, as can patient engagement in exercise. Although exercise is recommended as a component of HF management, adherence is consistently low. This is particularly troubling because exercise has great potential as a low-risk, low-cost intervention to improve functional status and quality of life while decreasing HF symptoms and hospitalizations in patients with HF. Low adherence is due in part to inadequate strength and inability to tolerate or sustain even low levels of activity. In this study, we propose to use neuromuscular electrical stimulation (NMES) to assist patient initiation of quadriceps strengthening in order to progressively increase low exercise tolerance. NMES has been shown to improve muscle strength, exercise capacity and quality of life, in samples less than 20 of male patients with HF. Larger sample studies are needed to demonstrate efficacy of this practice to jump start patients' abilities to benefit from formalized exercise program. The purpose of this double blinded, randomized, controlled, longitudinal study is to determine if NMES will increase muscle mass and strength, decrease sedentary time, and improve HF symptoms and exercise capacity, thus improving quality of life in patients with HF. It is hypothesized that with this increase in muscle mass, patients will improve overall exercise tolerance and capacity. In addition, after the intervention patients will be better able to tolerate an exercise program thus improving adherence to exercise recommendations. After 6 weeks of intervention, patients will be encouraged to participate in a formalized exercise program.
Clinicians slated for virtual visit rollout will be randomized (stratified by department) to either receive immediate virtual visit on-boarding (intervention arm) or delayed (3-months later) virtual visit on-boarding (control arm). The investigators plan to enroll no more than 200 clinicians. Any clinician in a department selected by the Brigham Health Virtual Care team for access to virtual visits is eligible, unless s/he saw less than 20 patients monthly over the last 6 months. The Brigham Health Virtual Care team will onboard all clinicians and provide virtual visit support as per their usual protocol. The primary study endpoint is third-available appointment, a well-adopted measure of access. Other secondary endpoints revolve around continuity, efficiency, utilization, safety, cost, and patient experience.
The primary objective of the study is to compare efficacy of metolazone and chlorothiazide as add-on therapy in patients refractory to loop diuretics with heart failure with a reduced ejection fraction (HFrEF). This will be a single-center randomized pilot study.
Background: People are living longer and are more likely to survive a heart attack if they have one. Longer life expectancy is good but it also means more people get chronic heart failure over time. This is a condition in which the heart doesn't pump blood as well as it should. Treatment of chronic heart failure has not improved much in a few decades. Researchers want to see if giving a dietary supplement to people with heart failure can help their heart function. The supplement is nicotinamide riboside (NR). Objective: To study how NR affects skeletal muscle function in people with heart failure. Eligibility: Adults ages 18-70 with clinically stable systolic heart failure Design: Participants will be screened with a medical history and physical exam. They will answer demographic questions and review their current medical treatments. They will have blood and urine tests. They will have an echocardiogram. This uses sound waves to test heart function. Participants will have 8 study visits over 16 weeks. At these visits, they will have some of the following: Repeat of screening tests Skin sample taken Skeletal muscle exercise Nuclear magnetic resonance (NMR) spectroscopy. Muscles will be measured while participants do foot exercises. Cardiopulmonary exercise testing. Participants may ride a stationary bike or walk on a treadmill. A facemask will analyze their breath. Heart and blood pressure measurements will be taken. Participants will take the supplement in pill form each day for 12 weeks. Pill bottles will be checked at study visits. Participants should not significantly change their activity levels during the study.
In this study the investigators are aiming to treat patients with acute heart failure with or without diabetes with Empagliflozin or placebo. Given the beneficial effects of Empagliflozin on heart failure hospitalization in the EMPA-REG OUTCOME trial, the investigators do expect a similar beneficial effect to be present in patients with acute heart failure. Acute heart failure is a state of hydropic decompensation resulting in dyspnea and congestions, caused by different etiologies of cardiac disease. Recompensation is reached by application of diuretic drugs and fluid restriction.
