A 37-year-old female with a 22 year history of insulin-dependent diabetes mellitus was admitted to the hospital 10 hours prior to death complaining of chest pain and shortness of breath.
Three months before, she had begun to experience progressive weakness and for the previous 3 weeks she noticed increasing dyspnea on exertion and worsening of a chronic cough.
Autopsy showed a 340-gram heart with extensive transmural reddish discoloration of the anterolateral portion of the myocardium of the left ventricle.
There was severe atherosclerotic narrowing of all coronary arteries especially the left anterior descending artery.
The lungs showed pulmonary edema and early bronchopneumonia.
