Myocardial lipofuscin reflects normal ageing rather than any cardiac pathology,[1] and does not need mentioning in the elderly.
Ruptured intercalated discs. Further information: Ruptured intercalated discs
Fibrosis. Further information: Myocardial fibrosis
Rectangular "Boxcar" nuclei: Look for myocardial hypertrophy, especially when enlarged. Otherwise, ruptured intercalated discs can cause square shaped nuclei.
