Explain of Cardiovascular Pathology

29.Myocardium, contraction band necrosis, microscopic

The earliest change histologically seen with acute myocardial infarction in the first day is contraction band necrosis. The myocardial fibers are beginning to lose cross striations and the nuclei are not clearly visible in most of the cells seen here. Note the many irregular darker pink wavy contraction bands extending across the fibers.
