Correlation Of Respiratory Rate Level And Trend Evaluation in Heart Failure Patients (CORRELATE-HF)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT00758121
Recruitment Status : Terminated (Inappropriate therapy associated with certain right ventricular (RV) lead complications may occur more frequently if the Respiratory Sensor is programmed On)
First Posted : September 23, 2008

Boston Scientific Corporation

Brief Summary:
The objective of the study is to determine if there is any relationship between respiratory rate and Heart Failure events.

Condition or disease Intervention/treatment
Heart Failure Device: Cardiac Resynchronization Therapy Defibrillator

Detailed Description:
The purpose of the CORRELATE-HF study is to collect RRT data in heart failure patients to gain a better understanding of how respiratory rate changes in relation to all cause clinical events as well as other diagnostic features, including but not limited to, activity level, heart rate, and lead impedance.
