ELEVATE-HFpEF 臨床研究 (ELEVATE-HFpEF)
駆出率を維持した心不全の個別化治療のための心拍ペーシング速度上昇のランダム化試験 (ELEVATE-HFpEF)
ELEVATE-HFpEF is a prospective, randomized, controlled, double-blinded, multi-center, global, interventional pivotal study evaluating the safety and efficacy of dual chamber personalized pacing compared to minimal or no pacing for the treatment of patients with heart failure with preserved ejection fraction (HFpEF).
調査の概要
詳細な説明
This study will evaluate a personalized cardiac pacing rate as a treatment for symptomatic heart failure with preserved ejection fraction (LVEF ≥50%). The intervention is designed to improve health status and other signs and symptoms of heart failure in patients with HFpEF. After enrollment, baseline data will be collected, and subjects will then have a pacemaker implanted. Following successful implant, and prior to pre-hospital discharge, subjects will be randomized 1:1 to one of two study groups. In the first group, subjects will have their pacemaker programmed to dual chamber pacing at a personalized cardiac pacing rate (treatment group) based on their LVEF and height. Subjects randomized to the second group will have their pacemaker programmed to receive ventricular pacing at a non-personalized rate to minimize interference with the subject's intrinsic heart rate (control group).
Subjects will complete 2-month, 6-month, and 12-month visits where data will be collected. At the 12-month visit, the second group (control group) will also be programmed to their personalized cardiac pacing rate. Subjects will complete 14-month, 18-month, and 24-month visits where data will be collected. Following the 24-month visit, additional long-term follow-up visits will occur annually until study completion. The estimated study duration is approximately 4.5 years representing an estimated 24-month enrollment period and 18-month follow-up period.

実験的:Personalized Pacing Therapy (Treatment Group)
The treatment group will receive a qualifying Medtronic dual chamber pacemaker limited to Astra XT or Azure XT and programmed to provide dual chamber pacing at a personalized cardiac pacing rate determined by patient height and baseline LVEF percentage. |
Personalized cardiac pacing treatment based each patient's height and baseline LVEF. |

Primary Efficacy Objective: Hierarchical composite endpoint of cardiovascular mortality, urgent HF events, HF events requiring an oral diuretic intensification (ODI), change in KCCQ, change in six-minute walk test distance, and change in NT-proBNP.
時間枠:Follow-up duration for endpoint analysis is 12-months.
|
Cardiovascular mortality, urgent heart failure events, and ODI heart failure events will be collected as they occur. The Kansas City Cardiomyopathy Questionnaire (KCCQ); (range of score is 0 to 100), 6-minute walk test (distance in meters), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) (picograms per milliliter, pg/mL) will be collected at Baseline and the 12-months visit. Treatment and control groups will be compared using a win ratio. |
Follow-up duration for endpoint analysis is 12-months.
|
|
Primary Safety Objective: Percentage of patients with major complications related to the system or procedure.
時間枠:12-months post pacemaker implant attempt.
|
Adverse events will be collected as they occur. Adverse events will be adjudicated for their relationship to the implant procedure and system. Severity of adverse events related to the procedure or system will be reviewed to determine if they are major complications. Major complications are defined as complications related to the system or procedure that result in one or more of the following: death, hospitalization, prolonged hospitalization by at least 48 hours, additional surgical intervention, system modification (e.g., reposition, replacement, or explant), and/or permanent loss of device function due to mechanical or electrical dysfunction of the device. The percentage of patients undergoing a pacemaker implant attempt who experience a major complication related to the system or procedure at 12 months. |
12-months post pacemaker implant attempt.
