ALT: alanine aminotransferase, AST: aspartate aminotransferase, AChR: acetylcholine receptor, BNP: B-type natriuretic peptide, BUN: blood urea nitrogen, CK-MB: creatine kinase-myocardial band, CRP: C-reactive protein, DM: diabetes mellitus, ESR: erythrocyte sedimentation rate, HbA1c: hemoglobin A1c, HCO3: bicarbonate, MI: myocardial infarction, MuSK: muscle-specific kinase, PaCO2: partial pressure of carbon dioxide (arterial), PaO2: partial pressure of oxygen (arterial), TSH: thyroid-stimulating hormone, T4: thyroxine, WBC: white blood cell count, MG: myasthenia gravis. Here, NPPB is linked to myocardial infarction.
