Detailed Description

Title

MARC (Markers And Response to CRT) - Prospective CRT study

Sponsor and study management

The MARC study is being sponsored by all participants of the COHFAR project as being defined in the COHFAR project agreement (Medtronic, UMCU, AMC, MUMC, VUMC, UMCG and ICIN). Study management will be done by Medtronic.

Purpose

To investigate the relation of a set of (bio)markers and response to Cardiac Resynchronization Therapy (CRT); the interrelationship as well as the potential predictive power of these (bio)markers on improvement and/or deterioration of cardiac function, cardiac geometry (reverse re-modeling during CRT) will be evaluated.

(Bio)markers include but are not limited to: collagen, genomic markers, molecular markers, electrocardiographic markers, echocardiographic markers, arrhythmogenic markers and markers for renal function: blood urea nitrogen (BUN), serum creatinine, glomerular filtration rate (GFR).

Design:

This is a multi-center, exploratory, prospective, interventional post-market release, non-randomized, study.

Medical device:

For reasons of uniform therapy delivery and homogeneity of (device diagnostic) study data, only Medtronic CRT-Defibrillator devices are used in this study with CareLink transmission functionality, OptiVol and Cardiac Compass report. Any commercially available leads can be used upon discretion of the investigator. All CRT-D devices and additional components (leads, programmer) incorporated in this study are CE-marked and market-released devices and used within the intended use of these devices.

Objectives:

Primary objective

• To investigate the relationship between a set of (bio)markers and response to cardiac resynchronization therapy (as measured by echocardiography) at 6 months.

Secondary objectives

• To investigate the relationship between a set of (bio)markers and response to cardiac resynchronization therapy (as measured by echocardiography) at 12 months
• To investigate the relationship between (bio)markers and atrial fibrillation during follow-up
• To investigate the relationship between (bio)markers and ventricular tachycardia/ fibrillation and/or appropriate shocks during follow-up
• To investigate the relationship between (bio)markers and reverse remodeling
• To relate baseline cardiac anatomy, function and mechanical dyssynchrony by cardiac MR and PET imaging in a subset of patients to CRT-response and to atrial and ventricular arrhythmias.

The biomarkers include:

• Genomics (while blood cells): candidate gene approach with micro-RNA's (analysis will be performed at the Genetics Core laboratory at study end. A inal list of micro-RNA's will be determined at study end).
• Blood markers (serum or plasma) are but not limited to: biomarkers of fibrosis, inflammation, cardiac damage, hemodynamic stress and extra-cardiac markers and will be analyzed at the Blood Biomarkers Core laboratory at study end.
• CMR Imaging at baseline for patients enrolled at the VUMC, AMC and UMCU investigational centers: function, anatomy, hemodynamics, global and local mechanical dyssynchrony assessment (tagged MR, CURE, torsion), Scar Imaging (DCE-MRI) will be measured.
• PET Imaging for patients enrolled at the VUMC, AMC and UMCU investigational centers: Perfusion (Adenosine), Innervation withHED tracer will be performed.
• Electrocardiography: Beat-to-beat Variability of Repolarization (BVR) / Short-Term Variability (STV) protocol
• Echocardiography: function and structure (including but not limited to LVEDD, LVESV, LVEDV, LVESVi, LVEF, MR, LVFT, IVMD, atrial volumina), in combination with electrocardiographic investigation: PA-TDI (P-wave duration). Echo 2D-Speckle Tracking: Radial Strain, Septal Rebound Stretch, standard deviation of Time to peak systolic Strain (final set of parameters will be determined at study end).
• Clinical parameters including among other coronary artery disease, Body Mass Index, gender, Myocardial Infarction at baseline.

All blood samples will be taken from peripheral venous blood and during implant also from the coronary sinus.

Additional prospective analysis:

• HF monitoring: intra-thoracic impedance (Optivol), patient activity, heart rate variability, Cardiac Compass arrhythmic episodes, continuously recorded through Carelink
• Electrical markers: arrhythmogenic markers (final list of markers to be determined at study end).
• Correlation of AT/AF episodes as detected by Carelink with baseline PA Tissue Doppler Imaging data.
• Correlation of echo strain measurements and MRI strain measurements
• Occurrence of clinical events during long-term follow-up; clinical events include:

• Cardiovascular hospitalizations
• Heart failure hospitalizations
• All-cause mortality
• Heart transplantation
• Acute implantation of a left ventricular assist device
• Atrial and ventricular arrhythmias including atrial fibrillation, atrial flutter, atrial tachycardia, ventricular tachycardia, ventricular fibrillation, as documented by continuous device diagnostic monitoring through CareLink

Subject selection:

The study will enroll 240 symptomatic heart failure patients (NYHA functional class II-III) with a reduced left ventricular ejection fraction and a prolonged QRS duration as measured prior to implantation of a cardiac resynchronization device (CRT-D). All patients will be followed for 1 year after implant. Each patient will visit the clinical site at baseline, 1-month, 6-month and 12 month follow-up. The total study duration will be 3 years. The 5 participating clinical institutions are all located in the Netherlands and member of the COHFAR project which is a partnership of the Center for Translational Molecular Medicine (CTMM) and Universitair Medisch Centrum Utrecht (UMCU), Universitair Medisch Centrum Groningen (UMCG), Academisch Medisch Centrum (AMC), VU Medisch Centrum (VUMC), Maastricht Universitair Medisch Centrum (MUMC), Medtronic and MSD with support from the Dutch Heart Foundation.

Treatment:

Each study subject will receive cardiac resynchronization therapy (CRT-D) according to the ESC/AHA guidelines and per local hospital routine. Additionally, optimal medical therapy for heart failure is up to the investigator's discretion.
