Sudden Natural Death

Sudden natural death (SND) is a death that occurs without warning within minutes to hours of the onset of symptoms. It is usually caused by an underlying medical condition, such as a heart attack, stroke, or infection. SND is a leading cause of death in the general population, accounting for over 250,000 deaths each year in the United States. Early identification of risk factors and implementation of preventive strategies can reduce the burden of SND. Diagnostic testing, such as electrocardiograms (ECG) and laboratory tests, may help to identify and treat underlying conditions that predispose to SND. Treatment options, such as lifestyle modifications, medications, and surgical interventions, may be appropriate for some individuals.
