Gedetailleerde beschrijving
This study is a pilot, open-label, non-randomized feasibility investigation of Cardiac Neuromodulation Therapy (CNT) in patients with high blood pressure and heart failure who are indicated for dual-chamber pacemaker implantation or replacement. The purpose of the study is to assess the feasibility of applying CNT and to evaluate its effects on blood pressure, heart failure status, and cardiac function at rest and during exercise over a follow-up period of up to 12 months. Eligible participants who provide informed consent and meet all inclusion and exclusion criteria will receive implantation of the Moderato Plus device. Following implantation, participants will complete scheduled study visits including two baseline visits and follow-up visits at approximately 3, 6, and 12 months. Study assessments may include blood pressure measurements, New York Heart Association (NYHA) functional class, echocardiographic evaluations, laboratory biomarkers, functional exercise testing, and patient-reported outcome questionnaires. At selected visits, cardiac performance during rest and standardized exercise conditions will be assessed to compare responses with CNT therapy activated and deactivated according to a predefined protocol. These comparisons are intended to evaluate short-term physiological responses to CNT and support feasibility assessments.
The first group of enrolled participants will undergo initial study assessments prior to long-term CNT activation to confirm the feasibility and appropriateness of the evaluation procedures. Based on this review, the study will continue as planned. Upon completion of the study follow-up, CNT therapy will be discontinued, and participants will resume standard clinical care.

Change in Cardiac Output During Supine Exercise
Tijdsspanne: 6-months
|
Cardiac output measured during supine rest and graded supine bicycle exercise using thermodilution techniques, with CNT activated and deactivated, at baseline and at 6 months.
Results will be summarized as the change in cardiac output during exercise between baseline and follow-up.

Change in average daytime and nighttime systolic blood pressure measured by 24-hour ambulatory blood pressure monitoring (ABPM), comparing baseline and the 3-month visit.
|
3-months
|
|
Change in Office Blood Pressure Measurements
Tijdsspanne: through study end, an average of 1 year
|
Change in office-based systolic and diastolic blood pressure measurements at each study visit compared to baseline.
|
through study end, an average of 1 year
|
|
Change in NYHA Functional Class
Tijdsspanne: at 3 months and 12 months
|
Change in New York Heart Association (NYHA) functional classification assessed at Visits 4 (3 months) and 6 (12 months) compared with baseline.
|
at 3 months and 12 months
|
|
Change in Kansas City Cardiomyopathy Questionnaire (KCCQ) Score Overall Summary Score
Tijdsspanne: Baseline through study end, an average of 1 year
|
Change in patient-reported health status as measured by the 23-item Kansas City Cardiomyopathy Questionnaire (KCCQ-23) Overall Summary Score, comparing follow-up assessments with baseline values.
The KCCQ-23 is a validated, disease-specific instrument consisting of 23 items, with scores ranging from 0 to 100, where higher scores indicate better health status (fewer symptoms and physical and social limitations).
