研究概览
简要总结
The purpose of this study is to obtain observational data allowing for the preliminary assessment of the utility of a noninvasive physiologic monitor for monitoring of patients with congestive heart failure.
详细描述
The study proposes to utilize the CoVa™ Monitoring System, a novel body-worn sensor that remotely monitors thoracic fluid, heart rate, heart rate variability, respiration rate, skin temperature, posture, and, using transmitted waveforms, stroke volume and cardiac output to evaluate the system's monitoring capabilities in individuals recently hospitalized for congestive heart failure. The data acquired through this study will play a critical roll in developing future interventional studies that will allow patients with HF to potentially receive better and more timely treatment in the home setting, decreasing hospitalizations and improving quality of life.

入选标准
- •Adults over age 18
- •Have wireless internet access within their homes.
- •Acute hospitalization with a primary diagnosis of acute decompensated heart failure (ADHF) diagnosed on the basis of all of the following:
- •Onset or worsening of dyspnea within the past 2 weeks
- •Physical exam (at least 1 present):
- •Rales/ Crackles on auscultation

结局指标
主要结局
Track physiologic parameters among patients with ADHF and explore predictive algorithms to allow for early ID of patients at risk of ADHF.
时间窗: 65 days
* To track on a daily basis important physiologic parameters among patients with a primary diagnosis of acute decompensated heart failure (ADHF) beginning at the time of their hospitalization and then continued for up to 60 days after discharge, in order to better understand their inter- and intra- individual variability and compare this to standard monitoring including daily weights. * To explore the development of predictive algorithms to allow for the early identification of patients at risk of acute decompensation and/or HF hospitalization.
次要结局
- Compare transthoracic impedance in individuals who already have a Medtronic implanted device with OptiVol technology.(65 days)
