Cardiac arrest related to brain inflammation?

Cause of death: Brain swelling (edema) will eventually cause the brain to herniate through one of the layers of protective scaffolding. This usually leads to wild fluctuations in blood pressure and rapidly to respiratory and cardiac arrest. However, the cause of death is the cause of the brian edema, not the cardiac arrest.

Probably not: I think that in this case, the cardiac arrest happened to occur in a patient with brain inflammation. I don't necessarily think they are related. Cardiac arrest, when the heart stops beating, can be caused by a whole host of things.
