What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

  • Procedures mentioned: Heart tracing (ECG), Blood draws, MRI scans

Only what the study's summary and detailed description on ClinicalTrials.gov say. Time periods may describe the whole study or a part of it — ask the study team what applies to you.

Show the study's own words
  • "Patients are followed longitudinally for clinical, ECG, genomic and proteomic markers and for index events."
  • "If a ventricular arrhythmia is detected blood will be drawn and a digital ECG will be performed as described for the 6 month follow up visits."
  • "At alternate visits (every 6 months) the patient will be evaluated by an attending electrophysiologist, a 60cc blood sample will be obtained, a 5-minute digital ECG, and any additional laboratory and diagnostic testing will be performed as clinically indicated."
  • "To determine if cardiac magnetic resonance imaging (CMR) performed around the time of PG replacement identifies patients who will experience ASD after PG replacement. 3."
  • "To determine if baseline levels and changes over time (up to 5-years) in clinical ECG, epigenetic, serum protein and metabolite markers predict ASD, overall survival and trajectory of the heart failure (HF) phenotype in patients with a primary prevention ICD. 5."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

The overall hypothesis of this study is that subtle interactions between structural (substrate) and functional (trigger) abnormalities of the heart, some of which are genetically-determined, can be used to identify patients at high risk of sudden cardiac death (SCD). Such information may be used to better define patients most likely to benefit from replacement of an internal defibrillator (ICD). The prospective, observational study to enroll, categorize and follow patients who receive an ICD pulse generator replacement for primary prevention of SCD (PROSe-ICD) was established to : 1. to gain a better understanding of the biological mechanisms that predispose to SCD 2. to develop readily determined clinical, electrocardiographic, genetic and blood protein markers identify patients with an increased risk of dying suddenly

Compensation is read from the study's own description and may be missing — always confirm with the study team.
