Not sure of her COD, but that's the 3rd or 4th one, in that age range this past year alone.
Long term Testosterone use in women causes major coronary issues. A few have died in their sleep of "natural causes" / heart attack. (Again, just in this past year, and right around that age).
Long term use isnt good for anyone, but mens bodies can handle higher test than woman's, all should be doing bloods, monitoring, etc.-
People that dont do bloods, when using are a bit brainless IMO. Will tell you if your blood is like jelly, or flowing nicely. They also have the coronary calcium scoring tests nowadays, no Dr. referel needed, only 100.00, and will show you if you have buildup, and how much. **groan**
