Active clinical trials for "Heart Failure"

Objectives: 1.- To evaluate the changes in health care and use of services in patients with chronic diseases such as chronic obstructive pulmonary disease (COPD), heart failure and major depression between 2017-2019 and the years 2020-2022, COVID pandemic period, and to see their relationship with clinical outcomes (in terms of mortality, admissions, death, current situation of his disease) and changes in health-related quality of life. 2- To evaluate the health care provided to a cohort of patients diagnosed with SARSCOV-2 (COVID-19 positive) during 2020 based on accessibility, equity and outcomes obtained. 3-To evaluate the evolution of the cohort of patients diagnosed with SARSCOV-2 after two years of follow-up since their diagnosis and create clinical prediction rules for the persistence of symptoms. Methodology. Four cohorts already created in previous projects are included: three of chronic patients, COPD, heart failure, major depression, all of 2017, and for which baseline information is available for follow-up of the health care they received in the 2017-19 period compared to that received during the 2020-22 period and to see the changes in their health-related quality of life from baseline based on generic and specific questionnaires for each of the pathologies included. Another cohort of positive and admitted patients for COVID-19 in 2020 is included, in whom the services received will be evaluated and recorded symptoms persistency that may have had up to two years after their index admission to develop tools for predicting the persistence of symptoms in the medium-long term.

The primary aim of this observational registry is to evaluate the efficacy of CCM in patients with heart failure with mid-range or reduced EF and diagnosis of TTR amyloidosis. The efficacy will be evaluated in terms of composite of occurrence of heart failure-related hospitalizations and/or acute intravenous interventions (IVI) at 12-month follow up compared to those reported 12 months before CCM implantation. Among the secondary endpoints, clinical functional status, quality of life, drug changes and Echocardiographic parameters will be evaluated and compared from baseline to follow up.

The purpose of the Screening for Advanced heart failure IN stable ouTpatientS (SAINTS) study is to determine the prevalence of advanced heart failure (HF) in symptomatic patients with HF and reduced left ventricular ejection fraction (HFrEF), corresponding to the New York Heart Association functional class II-III. Recognition of advanced HF is a challenge for physicians and under referral for advanced management is a considerable problem. There are excellent treatment options for patients with advanced HF, i.e. heart transplantation or left ventricular assist device (LVAD) implantation, and outcomes with these therapies are considerably better if patients are treated before irreversible end-organ damage occurs. International consensus highlights the importance of timely recognition and referral of these patients to advanced HF centers. The investigators aim to screen patients with symptomatic HFrEF who are followed in Danish HF clinics in the Copenhagen region with echocardiography, cardiopulmonary exercise test, 6 minute walk test, and NT-proBNP. The investigators hypothesize that 20% of patients with symptomatic heart failure followed in HF clinics in the Copenhagen Region will fulfill the modified criteria for advanced HF from the HFA-ESC (primary end-point in the study)(Reference 1). Patients who are identified with advanced HF will be offered right heart catheterization, guided by ultrasound and inserted through the internal jugular vein, determining pulmonary capillary wedge pressure, cardiac index, central venous pressure, mean pulmonary artery pressure, and central venous oxygen saturation. Patients not fulfilling criteria for advanced HF will be offered right heart catheterization consecutively until 50 patients have been examined (this group will be a comparator group to the patients with advanced HF). Patients identified with advanced HF will be offered listing for HTx or LVAD if an indication without a contraindication is present. Patients who fulfill the primary endpoint of modified HFA-ESC criteria for advanced HF, and are ineligible for, or unwilling to undergo HTx or LVAD implantation will be invited to participate in the SAINTS B study.

Left ventricular assist device (LVAD) candidates will be comprehensively evaluated at our center, including clinical evaluation, echocardiography, right heart catheterization, cardiopulmonary exercise test and laboratory exams. following this evaluation, patients will be treated with inotropes, diuretics, uptitrated neurohormonal therapy. vitamin and iron deficiencies will be corrected and the patients will be referred for coronary interventions and cardiac resynchronization therapy appropriately. The need for LVAD implantation will be reevaluated according to the patient's clinical condition, echocardiography and laboratory findings.

This study will employ a randomized order, double-blind, repeated measures dose ranging design. This design was chosen in order to generate multiple within-subject serial loop diuretic dose response exposures. The overall study schema will include 75 heart failure (HF) patients.

The goal of this research study is to understand whether an at-home exercise program started after hospitalization for HFpEF, and continuing for 4 weeks following discharge from the hospital, can preserve or improve physical function.

This research will be one of the first hospital-based studies to comprehensively evaluate the epidemiological characteristics of sleep disordered breathing (SDB) in patients with Congestive Heart Failure (CHF). This prospective, observational cohort, single center study will include all consecutive CHF outpatients from the specialized heart failure clinic in Medical Department, Hospital Taiping, Malaysia irrespective of preserved or depressed Left Ventricular Ejection Fraction (LVEF). All participants will be subjected to an attended in-laboratory polysomnogram (PSG). It is anticipated the frequency and types of SDB to be variable compared to western data as this subject remains understudied in the South East Asian population. This research utilizes PSG rather than Portable Sleep Testing (PST) as seen in preceding studies for the diagnosis of SDB to prevent underdiagnosing SDBs and clearly distinguishing Obstructive Sleep Apnea (OSA) and Central Sleep Apnea (CSA).

The main purpose of the study is to evaluate the ability of the Tauropace to reduce major cardiac implantable electronic device (CIED) infections through 12-months post-procedure following CIED in heart failure participants. The secondary endpoint is to prospectively characterize the performance of Tauropace in participants whose CIED system includes a transvenous RV defibrillation lead.

This is a prospective interventional study to better understand i) the prevalence of Obstructive Sleep Apnea (OSA) in Heart Failure with preserved Ejection Fraction (HFpEF), ii) its hemodynamic correlates, and iii) the impact of intervention with Continuous Positive Airway Pressure (CPAP) on quality of life.

Invasive pressure-volume (PV) loop measurements have the potential to confirm or refute earlier computer simulations and animal studies regarding changes in cardiovascular physiology induced by (veno-arterial) ECMO. PV loop analysis could create a framework for the (ICU-) clinician for VA-ECMO weaning guidance, based on a patient's individual hemodynamic profile. PV loop measurements may, in future, serve as a guide for which patient would benefit most from (prolonged) VA-ECMO support or which patient would require additional LV unloading. Within the context of PLUTO-I, patients on VA-ECMO support who are eligible for weaning from VA-ECMO will undergo biventricular PV loop measurements on different intensities of extracorporeal support.
