THBD and ST Elevation Myocardial Infarction: This study evaluated the levels of serum thrombomodulin (TM), heart-type fatty-acid-binding protein (H-FABP), pentraxin-3 (PTX-3) and galectin-3 (Gal-3) to determine their utility in distinguishing between ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI).
