急性心肌梗死第一天心肌纤维的变化

急性心肌梗死第一天组织学上表现为明显的收缩带坏死。在大多数可见细胞中,心肌纤维的横纹丢失,细胞核模糊。注意在纤维上有许多无规律暗红的呈波浪状的收缩带经过。

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.
