Study Summary
The purpose of the study is to identify if the combined use of cardiac troponin enzyme (cTnT) and brain natriuretic peptide (BNP) can predict Heart Failure (HF)improvement and all-cause mortality in patients implanted with cardiac pacemaker-defibrillation devices (CRT-D). Novel biochemical markers identifying patients with high risk cardiac mortality detected by plasma protein analysis will also be evaluated. Hypothesis #1: The combined use of cTnT and BNP at just before implant will predict and risk stratify all cause mortality or HF hospitalization up to 12 months. Hypothesis #2: The change in levels of said biomarkers at different points of follow-up can predict response to CRT through 12 months. Hypothesis #3: The levels of a panel of novel inflammatory mediators, namely chemokines, will be correlated with improvement in 6-minute walk testing, quality of life, and left ventricular ejection fraction in CRT patients.
