Imaging Techniques for Identifying Factors of Sudden Cardiac Death Risk

Functional Energetics and Imaging for Phenotypic Characterization of Patients at Risk for Sudden Cardiac Death

Who can join

Ages 18 and older · All sexes

Inclusion Criteria:

* Left ventricular ejection fraction \<or = 35%

Exclusion Criteria:

* History of sudden death (secondary prevention)
* Contraindication to undergoing MRI (metallic implant, pacemaker, etc.)

About the 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.
