Heart Function in Patients Assessed for Sleep Apnoea
Heart Failure With Preserved Ejection FractionSleep Disordered Breathing4 moreThis study aims to determine the prevalence and prognosis of heart failure with preserved ejection function (HFpEF) among patients being assessed for sleep disordered breathing (SDB).
Device-based QRS Evaluation
Heart FailureThe purpose of this study is to collect simultaneous surface electrocardiogram (ECG) recordings and Cardiac Resynchronization Therapy (CRT) intracardiac electrogram (IEGM) recordings of variations in electrical synchrony.
Acute Heart Failure Study in Patients Admitted to Emergency Department for Dyspnea
Heart FailureNo studies have analyzed the predictive value of different anamnestic and clinical signs for the diagnosis of acute heart failure (AHF) in patients admitted to emergency department. That's why the expert group of the AHF of South West of France mobilizes to conduct this study to evaluate the diagnostic predictive value of different anamnestic and clinical signs for the diagnosis of AHF to emergencies.
Pilot Study of the QI Device for Monitoring of Patients With Congestive Heart Failure
Heart FailureThe present study proposes to utilize a novel, wearable device, QI Device, which has multiple sensors embedded in a "wrist-watch" in order to explore its monitoring capabilities in individuals with congestive heart failure.
Improving Heart Failure Outcomes Rural
Heart FailureThis study will test if standardized care helps patients feel better, if it can be implemented in rural hospitals, and find out which healthcare processes and outcomes are most important to heart failure patients.
SchlaHF-XT-Register. Sleep Disordered Breathing in Heart Failure Register
Heart Failure (HF)The SchlaHF XT Registry is a longitudinal study of patients with heart failure (HF). The study aims to understand the importance of diagnosis and treatment of sleep disordered breathing (SDB) on HF with the following questions: How often does SDB occur in HF? What forms of SDB occur and how are they treated? How does SDB develop over time? How does the heart failure therapy affect SDB? What is the treatment adherence of patients treated? Does SBD and its treatment affect the survival of heart failure patients?
The Use of Pramipexole and Other Dopamine Agonists and the Risks of Heart Failure and Pneumonia...
Heart FailureStudy to assess the risk of incident heart failure associated with the use of pramipexole compared with other dopamine agonists and additionally, to assess the risk of incident heart failure associated with the use of dopamine agonists in comparison with no use of dopamine agonist therapy
Quadripolar CRT-D On Currently Approved Lead SystemS
Heart FailureThe purpose of the study is to evaluate different ways to program around extracardiac stimulation.
The Regulation of Pulmonary Vascular Resistance in Patients With Heart Failure
Diastolic Heart FailurePulmonary HypertensionPeripheral blood and blood following a pulmonary wedge pressure will be obtained from patients undergoing right heart catheterizations.
The Clinical Significance of Portal Hypertension After Cardiac Surgery: a Multicenter Prospective...
Surgery--ComplicationsCongestive Heart Failure3 morePortal flow pulsatility detected by Doppler ultrasound is an echographic marker of cardiogenic portal hypertension from right ventricular failure and is associated with adverse outcomes based on previous studies performed at the Montreal Heart Institute. This multicenter prospective cohort study aims to determine if portal flow pulsatility after cardiopulmonary bypass separation is associated with a longer requirement of life support after cardiac surgery.
