C.O.D.

The funeral home received the death certificate. It listed "enlarged heart due to coronary disease" as the cause.

From what I understand this means that what most likely happened was something like this. The heart detected there was too much blood in his heart and tried to counteract that situation by slowing down the blood supply. Creating a scenario where there was not enough blood to allow the body function.

The condition has a number of causes and the exact cause in Mark is not known. Doctors encouraged the rest of the adult family members to have check-ups and ask to be checked for this condition.

Given the fact that my Grandfather, Father, and Brother have all been diagnosed with heart conditions in the past two years it's probably something we should look into.
