NPPB and gas gangrene: Of those, the most studied areTroponin (I and T), brain natriuretic peptide (BNP) and its inactive byproduct:N-terminal-pro hormone BNP (NT-proBNP), Creatine Kinase-MB (CK-MB) and Myoglobin.In patients with TTS, myonecrosis biomarkers such as troponin, CK-MB andmyoglobin are elevated by a lower scale compared to ACS, due to significantlyless tissue injury [33].
