Sudden cardiac death in the elderly

Senile sudden cardiac death (SCD) in the elderly refers to an unexpected natural death caused by a cardiac cause within 1 hour of the onset of symptoms. In the United States, the incidence of sudden cardiac death is estimated to be 200,000 to 400,000 cases per year, accounting for more than 50% of all cardiovascular deaths. After sudden cardiac death, the success rate of resuscitation is estimated to be only about 20%. And it is estimated that 80% of patients with sudden cardiac death cannot survive to discharge, and 50% of surviving patients die within 3 years. It can be seen that sudden cardiac death is one of the main causes of death that jeopardizes people's lives, and it should arouse high vigilance among clinicians and patients, and carry out effective preventive treatment at an early stage.
