It is possible that disruption of circadian rhythms may be responsible for predisposing shift workers to vascular events.

In 2005, the American Heart Association published their ‘chain of survival’ concept for resuscitation of patients with out of hospital cardiac arrest. The chain will be familiar to many practitioners, comprising four links: early access to emergency medical care, early cardiopulmonary resuscitation, early defibrillation and early advanced cardiac life support.
