Brief Answer:
The autopsy states that heart disease and head injury lead to death.

Detailed Answer:
Hello and welcome to 'Ask a Doctor' service.

I have read your query and here is my advice.

This partial autopsy report states that the cause of death was primarily the cardio-respiratory arrest due to chronic heart and pulmonary disease and head trauma.

The autopsy findings of the head injury (scalp lacerations, skull fracture, and faint subarachnoidal hemorrhage) are considered as moderate.

Hope you found the answer helpful.

Let me know if I can assist you further.

My heartiest condolences to you for the loss.

Kind Regards
