Heart failure

Heart with myocardial fibrosis

Pathology of the cardiac muscle is sometimes found in rabbits that showed no signs of heart disease during life. Some rabbits with cardiomyopathy die suddenly and without warning. Some may go into congestive heart failure before they die. In a few cases of unexpected death, the heart is visibly abnormal but in many cases it looks normal. Histopathological examination of the heart and other organs maybe necessary to establish the diagnosis.
