Skippy's autopsy pictures

Skippy had been diagnosed with lymphoma just over 2 months before he was put to sleep. The write-up about his illness is on his page. Then during a heatwave in July he developed what I can only describe as acute heart failure. He obviously must have been developing his enlarged heart over quite some time but never showed any symptoms. I keep wondering if the high doses of prednisolone that he got for his lymphoma accelerated his cardiomyopathy. I wonder if pred causes muscle loss, could it have affected his heart muscle and led to a rapid and eventually sudden worsening? Because he suddenly developed breathing problems and was breathing very fast with an open mouth and could, in the end (1 & 2 days after it started), not get comfortable or even sleep. No coughing though so not sure if his fast breathing was because of fluid in the lungs or because the heart had got too weak. Or maybe he was breathing fast because he had suddenly become anaemic because of his spleen, another option that I never thought of before and can't check anymore... Grateful for any veterinary input, should any vet ever come across this. Unfortunately I didn't send off tissue samples because I thought he only had lymphoma and that it would be clearly visible with tumours everywhere that I only wanted to photograph but not send off. So I didn't request a tissue sample "pot" from the vets. Then it turned out that I found a dilated heart and no visible lymphoma- unless it was in the spleen and lymph nodes.
