Abstract
Diabetes mellitus has long been linked to an increased risk of sudden cardiac death. However,
the magnitude of this association, and the mechanism accounting for this phenomenon, have
not been precisely defined. In this review, we evaluate the epidemiological data pertaining to
the association between diabetes mellitus and sudden cardiac death and discuss various
proposed mechanisms that may account for this relationship. Potential factors contributing to
the increased risk of sudden cardiac death observed in patients with diabetes mellitus include
silent myocardial ischemia, autonomic nervous system dysfunction, abnormal cardiac
repolarization, hypoglycemia, a hypercoaguable state secondary to diabetes mellitus, diabetic
cardiomyopathy, and impaired respiratory response to hypoxia and hypercapnea.
We conclude that diabetes mellitus does appear to be associated with an increased risk of
sudden cardiac death. Although this increased risk is relatively modest, given the large number
of diabetic patients worldwide, the absolute number of sudden cardiac deaths attributable to
diabetes mellitus remains significant. Little evidence exists to support any specific mechanism(s)
accounting for this association. Further investigation into the pathophysiology of sudden cardiac
death in diabetes mellitus may yield improved risk stratification tools as well as identify
novel therapeutic targets.
