Sleep Apnea, Arrhythmias and Cardiac Reverse Remodeling in Heart Failure Patients
Sleep Breathing Disorders in the Responders to Cardiac Resynchronisation Therapy (CRT)Prospective, international, non-randomized, multicentre, clinical investigation (phase IV). The aim of the study is to investigate the correlation between HF, severe SBD, and AF in CRT-P patients at 6 months.
Correlation Between Peripheral Venous Pressure and Central Venous Pressure in the Cardiac Intensive...
Prospective StudiesHeart FailureIn patients admitted to a coronary care unit, what is the correlation coefficient and limits of agreement for paired measurements of peripheral venous pressure and central venous pressure at multiple time points during the patient's hospitalization?
HFpEF and Symptomatic Obstructive Iliofemoral Venous Disease Study
Heart Failure With Preserved Ejection FractionVenous DiseaseTo ascertain the potential symptom improvement assessed by Cardiopulmonary Exercise Testing (CPET) in subjects with heart failure with preserved ejection fraction (HFpEF) and nonthrombotic iliofemoral venous lesions and/or iliocaval obstruction defined by MR or CT venography AND CEAP Clinical Category ≥3 prior to venous stenting.
Collagen Markers in Heart Failure and Preserved Ejection Fraction
Left-sided Congestive Heart FailureAssessment of cardiac fibrosis by echocardiography (Speckle tracking), IRM (late-enhancement imaging), biology (markers of collagen turn-over) and proteomics
Prospective Evaluation of Heart Failure Patients With Central Sleep Apnea
Central Sleep ApneaHeart FailureCentral sleep apnea (CSA) has been associated with increased mortality and primarily occurs in patients with heart failure (HF). The primary purpose of this study is to document the natural progression of moderate to severe CSA in heart failure patients.
Home-Based Fluid Status Monitoring in Heart Failure Patients
Heart FailureThis is a prospective, multi-center, single-arm study enrolling adult patients who have been hospitalized for heart failure and subsequently discharged. For the duration of study participation, patients will obtain daily at-home bioimpedance measurements. Heart failure symptoms, medications, and re-hospitalizations will be tracked. Additionally, quality of life questionnaires will be administered at the beginning and end of study participation.
Home Outpatient Monitoring and Engagement to Predict HF Exacerbation
Heart Failure With Reduced Ejection FractionThe HOME PREDICT HF study looks at new ways to predict hospitalizations for heart failure. We will use a set of devices at home and surveys to collect information about patient's health. This study uses the Eureka app, a new study app developed by the University of California, San Francisco. The study is designed to happen remotely, using this application on a patient's smartphone, so that is as convenient as possible to participate.
New Echocardiographic Parameters for Prediction of Response to Cardiac Resynchronization Therapy...
Congestive Heart FailureEchocardiography parameters for cardiac dyssynchrony had no predictive value in current multicentric prospective studies concerning cardiac resynchronization therapy. Comprehensive echocardiography and new parameters as 2D and 3D strain, as well as 3D echo have been analyzed, but their definite value has not been proven yet.

The Use of Tolvaptan to Prevent Renal Dysfunction in High Risk Patients With Heart Failure-Pilot...
Heart FailureIt is well known that the use of loop diuretics in acute setting may decrease glomerular filtration rate (GFR) and increase serum creatinine leading to renal dysfunction. Loop diuretic induced elevation in serum creatinine can lead to increase in length of hospital stay and possibly morbidity. Previous studies have suggested that tolvaptan unlike aggressive loop diuretic therapy may not activate neurohormonal system nor decrease renal blood flow. These properties may make tolvaptan a useful addition to diuretic therapy to prevent renal dysfunction in high-risk patients. Therefore the primary objective of this study is to determine if the use of tolvaptan in combination with diuretic therapy may prevent development of renal dysfunction in high risk patients with heart failure. Hypothesis: Administration of tolvaptan in combination with continuous loop diuretic therapy in acutely decompensated heart failure patients at high risk for developing diuretic induced renal dysfunction will have a lower proportion of patients increasing their serum creatinine > 0.3 mg/dL within a 96 hour time frame as compared to patients just receiving standard of care continuous infusion diuretic.
