Active clinical trials for "Heart Failure"

In patients undergoing CRT device implantation a lead positioning in the coronary sinus is required. Even this part of the surgical procedure is challenging. In this study we compared retrospectively to methods of CS-lead implantation: conventional vs. EP-catheter guided.

The study will test a hypothesis that the remote monitoring with text and email alerts sent to study subject and optional family/other caregiver (Intervention 1) will have a higher return on investment compared to remote monitoring with nurse researcher follow-up telephone communication to study subject (on Blue alerts) or study subject's healthcare professional (on Red alerts) (Intervention 2) and self-monitoring without intervention (Control).

Observational study on ADHF patients at one site in Israel. After signing informed consent and undergoing screening assessments, eligible patients will record sentences into a smartphone. The app will upload the vocal data to the sponsor's servers for analysis. The patient will record at hospital: admittion, release. Before hospital release, if applicable and upon patient agrreement, an app will be installed in a smartphone in order to continue the recording at home.

This clinical investigation is designed to demonstrate the performance characteristics of the RAMP® cardiac tests analyzed on the RAMP® 200 by non-laboratorial Operators at the point-of-care when compared to the results for the same samples analyzed on the RAMP® Reader.

The purpose of the study is to evaluate a new way to examine cardiac function, using software developed at Caltech. The experimental device is software loaded on an iPhone. The iPhone is used to capture a pulse (waveform) by simply placing the iPhone lightly over the neck where the carotid pulse can be felt. In this study the information collected from the iPhone app is compared to cardiac function data obtained from the current gold standard for measuring cardiac function, cardiac magnetic resonance imaging (MRI). Subjects referred from cardiologists will also generally have echocardiography information available for comparison with the iPhone app. For the study, subjects will have completely non-invasive studies done in one setting: The iPhone app to capture the waveforms (over carotid and radial (wrist) arteries), tonometry (another non-invasive method using a modified stethoscope), standard pulse oximetry, followed by a 30 minute MRI examination of the heart. A second complete study will be done about 6 months after the first. The complete study session takes about 1.5 hours.

To identify the risk factors of the revisit of the adult HF patients in emergency department.

MADIT-CRT PAR is an FDA mandated follow-up registry for patients that participated in the MADIT-CRT IDE study examining long-term mortality. (MADIT-CRT IDE: NCT00180271)

The purpose of this study is to investigate the prognostic value of admission high-sensitivity troponin in patients with acute decompensated heart failure.

This 3rd phase of the ELEVATE study. The study is collecting data from an implanted CRT-D device to evaluate a new feature for future heart failure devices.

The Boston Scientific Energen family is capable of measuring the respiratory rate trend (RRT) on a daily basis and transmission of data via the Remote Monitoring technology. This may result in early detection of imminent decompensation at a presymptomatic stage. The study will assess the respiratory trends correlation with clinically relevant heart failure events.
