Cardiac Output Pulmonary Arterial Catheter Compared to FloWave™ 1000
Congestive Heart FailureIschemic Cardiomyopathy4 moreThe purpose of this study is to compare cardiac output results obtained using the thermodilution push technique with the Pulmonary Arterial Catheter (PAC) to the predicted cardiac output results obtained from the non-invasive FloWave™ 1000 device.
National Survey on Coronary Patients and Heart Failure Performed in 2 Patient Groups
Coronary PatientsHeart FailureThe purpose of this observational study is to compare frequency of attainment control goals through the more represented cardiovascular factor risk, dyslipidemia, among coronary patients with or without heart failure in cardiology consulting.
CRT Pilot Study for Children With Heart Failure
Chronic Pediatric Heart FailureTo collect information on pediatric patients receiving Cardiac Resynchronization Therapy (CRT) with permanent biventricular pacing (BVP) as a method of treating chronic heart failure.
Mechanisms in Heart Failure With Normal EF
Heart FailureThe guiding hypotheses are that (1) mechanisms in addition to diastolic dysfunction, while normal at rest, are compromised with stress, leading to symptoms of HF, and (2) that an increased proportion of the increase in LV diastolic pressures seen in HFpEF is mediated via exaggerated pericardial/right heart-LV coupling (restraint).
Decompensation Detection Study
Heart FailureTo gather data and analyze decompensation events.
Study of the Implantable Cardioverter Defibrillator (ICD) Intracardiac Electrograms
Congestive Heart FailureSudden Cardiac Death2 moreThe purpose of this study is to determine whether waveforms of the intracardiac electrograms, acquired through an ICD, can be used: to predict malignant ventricular arrhythmias, requiring appropriate ICD therapies, and to predict progression of heart failure in patients with ICD.
Monitor Patients With Acute Heart Failure
Heart FailureThis is a prospective, multi-center, non-randomized study to evaluate performance of an external monitor for heart failure patients
REGISTRY EVALUATION OF VITAL INFORMATION FOR VADs IN AMBULATORY LIFE
Congestive Heart FailureREVIVAL will establish a prospective, observational, multicenter patient cohort in ambulatory patients with chronic, advanced, systolic heart failure that will provide a greater understanding of their clinical trajectory (rates of hospitalizations, transplantation, MCSD use and death), and of how baseline clinical risk measures are related to prognosis.
Non-invasive Heart Failure Monitoring Using Novel Acceleration Sensors System
Heart FailureThe purpose of this study is to explore the feasibility of monitoring hemodynamic changes, which result from heart failure exacerbations, by recording the respiratory effort, chest wall dynamics and quantifying the development of dyspnea by using miniature mechanical sensors that are attaches to the chest.
REducing 30-day ADMIssions in posT-discharge Subjects (READMIT)
Acute Decompensated Heart FailureThe purpose of this observational study is to collect and characterize multiple physiologic data from a broad subset of subjects with acute heart failure (HF) Changes in physiologic data are expected to correlate with 30-day readmission rates in this population
