DETECTION OF EARLY ACUTE MYOCARDIAL-INFARCTION BY GOMORI TRICHROME ANILINE BLUE STAIN

A rapid one step Gomori trichrome with aniline blue (GTAB) stain is de scribed. The original Gomori trichrome stain was modified by replacing the light green stain with an aniline blue stain. The aniline blue st ained the necrotic myocardial fibers deep blue in hearts of patients u ndergoing autopsies following death due to early acute myocardial infa rction. The aniline blue not only stained the fibrous components of th e myocardial interstitium but also the necrotic myocardial fibers. The GTAB stain became very valuable in differentiating early acute hemorr hagic myocardial infarction from acute myocardial hemorrhage following coronary aorta bypass surgery.
