Syncope history may identify higher sudden-death proportion in dilated cardiomyopathy; hypothesis-generating and requires prospective validation before guiding interventions.
Does a history of syncope predict sudden cardiac death in patients with dilated cardiomyopathy?
In patients with dilated cardiomyopathy, a history of syncope is a strong predictor of sudden cardiac death, identifying a high-risk subgroup that may benefit from targeted interventions.
Fruhwald et al. (2008) studied this question.
