Diagnosis and Prognosis in Sudden Cardiac Arrest Survivors Without Coronary Artery Disease

Abstract

CMR identified a likely pathogenesis for sudden cardiac arrest in nearly half of survivors in whom coronary artery disease had been excluded. One in 3 subjects had MACE; risk doubled in those with a CMR diagnosis and some CMR parameters-late gadolinium enhancement, left ventricular ejection fraction, and especially right ventricular ejection fraction-associated with prognosis.
