Brief Summary:

The purpose of this study is to understand the behaviour of certain blood markers in patients with heart failure who undergo a cardiac device implantation procedure called cardiac resynchronization therapy (CRT). CRT is an effective treatment for heart failure, but up to 30% of people do not respond and have poor outcomes (1,2). Despite extensive investigation, identifying these patients continues to be a challenge. The study intends to describe the changes in these blood markers before and after CRT and to examine any potential clinical value.

The idea behind the study is that these blood markers alter in heart failure and change with CRT implantation. Furthermore the pattern of marker expression before implant and after may predict response and outcome.

Group/Cohort Intervention/treatment
Chronic Heart Failure Patients
Undergoing CRT implantation, all will be observed for 6 months and will be defined at the end of the observation period as responder or non-responder
Device: Cardiac Resynchronisation Therapy
Routine implantation of CRT - part of standard of care

Primary Outcome Measures :
  1. Clinical Response [ Time Frame: 6 months ]

    Two of three criteria must be fulfilled to be defined as a clinical response:

    1. New York Heart Association (NYHA) > 1 class reduction from baseline
    2. Minnesota Living with Heart Failure Questionnaire (MLHFQ) score < 5 from baseline
    3. Six minute walk test (6MWT) increase in baseline distance by 10%

    Mortality or heart transplantation within 6 months of implant will be defined as a non-response.

Secondary Outcome Measures :
  1. Major Adverse Cardiovascular Outcomes [ Time Frame: 12 months ]
    Composite score of all-cause mortality and first heart failure hospitalisation (admission requiring intravenous diuretics)

  2. Echocardiographic Response [ Time Frame: 6 months ]
    ≥15% reduction in left ventricular end-systolic volume

Biospecimen Retention:   Samples Without DNA
Participants with have peripheral and coronary sinus samples taken for plasma and serum.
