Active clinical trials for "Heart Failure"

This is a multi-site, non-randomized, data collection study. The purpose of this study is to investigate the cardiac electrical and mechanical function during LBBAP with different AV intervals.

In patients discharged following heart failure treatment, the consistency of blood volume status and components over time is unknown. The primary objective is to describe the rate of change, if any, of the plasma volume and red blood cell volume following hospitalization and discharge of patients with heart failure.

RV dysfunction has been associated with increased mortality in the ICU and cardiac surgical patients. Thus, early identification of RV dysfunction at less severe stages will allow for earlier intervention and potentially better patient outcomes. However, so far, no studies have reported prospectively the prevalence of abnormal RV pressure waveform during cardiac surgery and in the ICU. Our primary hypothesis is that the prevalence of abnormal RV pressure waveform occurs in more than 50% of cardiac surgical patients throughout their hospitalization. Those patients with abnormal RV pressure waveform will be more prone to post-operative complications related to RV dysfunction and failure in the OR and ICU.

In 2016, the European Heart Association defined the median ejection fraction heart failure for the first time. More research is needed to improve our understanding of this population, so as to make the best clinical decision and improve the prognosis. In this study, 3D-STI was used to evaluate left ventricular systolic function in heart failure with median ejection fraction.

Pulmonary Artery Compliance measurements will be obtained with the Respirix device in patients with congestive heart failure decompensation. Echocardiogram, weight measurements, and BNP will also be gathered as independent measures of decompensation in the clinic. Pulmonary Artery Compliance measurements will be made daily during the hospital stay. Patients can continue using the device at home for the next 3 weeks. Each patient will serve as their own control and relative changes from their baseline will be recorded for each parameter.

Retrospective, observational cohort study. Objectives: To identify intra hospital mortality risk factors in patients admitted admitted to cardiac intensive care units (CICU). The clinical main endpoint will be the observed percentage of deaths that occured during the year 2017 in french CICU. To identify the length of stay key determiners of patients admitted in french CICU. The study will use data from one of the french nationwide healthcare systems database (SNDS) : the national hospital discharge database (PMSI) to be precise.

This study assesses the potential of lung ultrasonography to diagnose heart failure.

Multicentre, prospective cohort study in patients with a history of HF with preserved or reduced ejection fraction admitted to hospital with acutely decompensated HF. Eligible and consenting patients will be enrolled at 3 Hamilton, Ontario area hospitals and receive 28-day ECG monitoring implemented at the time of hospital discharge. Patients will be followed for a total of 1 year from hospital discharge.

The INTERPRET Inotrope Evaluation and Research Patient Registry is a longitudinal, observational study designed to look at the demographics and outcomes of heart failure patients on inotropic therapy administered in the home or infusion suite setting. The data gathered in this registry will provide information on how a patient's quality of life and symptoms change over time while on inotrope therapy, and help healthcare providers to have a better understanding of the benefits and risks associated with bridge-to-treatment and palliative care.

The purpose of this observational registry is to collect clinical events and outcome data in 4 different study populations (cohorts), with a majority of Japanese subjects, that are at risk of sudden cardiac death (SCD) and heart failure (HF) events. These event rates will be compared with available published data mainly from Europe and the United States. Selected Subject Cohorts: Selected subject cohort with criteria for SCD (without spontaneous prior ventricular sustained arrhythmia) and de novo Implantable Cardioverter-Defibrillator (ICD) device treatment. Selected subject cohort with criteria for SCD and widely accepted standard cardiac resynchronization therapy (CRT) indication who received a de novo CRT-Defibrillator (CRT-D) device treatment. Selected subject cohort who are clinically expected to require >40% right ventricular pacing with a left ventricular ejection fraction (LVEF) ≤50%, any determined New York Heart Association (NYHA) Class, and receiving pacemaker (PM) or CRT-Pacemaker (CRT-P) therapy despite previous device history (de novo, box changes, system revisions or upgrades). Selected subject cohort with criteria for SCD fulfilling European Society of Cardiology (ESC) ICD or CRT-D therapy guidelines (2016) with an LVEF ≤35%, having 2 to 5 predefined SCD risk factors but do not have or had have a cardiac implanted defibrillator, CRT-D, PM, or CRT-P. The primary endpoint will report on the Composite rate of first appropriately treated ventricular arrhythmia (by anti-tachycardia pacing [ATP] or shock) or life-threatening symptoms associated to ventricular arrhythmia (defined as hemodynamic instability which requires treatment), whichever comes first under MADIT RIT Arm B or C programming conditions in a study population with a majority of Japanese subjects. This primary end point is assessed in the ICD/CRT-D implanted patient cohort. The all-cause mortality in subjects with a maximum of 3 risk factors (analyzed for MADIT II data) will be assessed in the Pacing (PM/CRT-P) patient cohort. The all-cause mortality will be assessed in the non-implanted subject cohort.
