Brown atrophy of the heart: Sign of Cardiac aging

Atheroma of an Artery: atherosclerosis

Myocardial infarction

Wavy fibers is an early sign of myocardial infarction

Myocardial infarction: Coagulative necrosis and a few inflammatory cells

Myocardial infarction: Coagulative necrosis, interstitial bleeding, and a few inflammatory cells.

Dilated heart in myocarditis

Dilated cardiomyopathy

Cardiomyopathy (trichrome stain): extensive fibrosis (blue) between the myocytes. The myocytes also vary in size.

Hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy : myofiber dysarray ; not all fibers are pulling the same direction. Thus the contraction is ineffective.
