Sudden Cardiac Death | Imaging Techniques for Identifying Factors of Sudden Cardiac Death Risk
Sudden Cardiac Death research study
What is the primary objective of this study?
Sudden cardiac death is a tragic event that strikes all age groups and is unfortunately
increasing in prevalence. Because it is difficult to predict those at highest risk, this
study is designed to test the hypothesis that new imaging techniques (magnetic resonance
imaging [MRI] and computed tomography [CT]) are useful for identifying factors which put
people at high risk for sudden death.
Who is eligible to participate?
- Left ventricular ejection fraction <45%
- Planned implantable cardioverter-defibrillator (ICD) implantation for clinical
indications (primary prevention)
- History of sudden death (secondary prevention)
- Contraindication to undergoing MRI (metallic implant, pacemaker, etc.)
Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Sudden Cardiac Death
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
