Laboratory examinations indicated acute cardiac failure (troponin I: 653.4 pg/ml (reference range < 20 pg/ml); brain natriuretic peptide (BNP): 540.5 pg/ml (reference range < 20 pg/ml); c-reactive protein (CRP): 2.66 mg/dl (reference range < 0.14 mg/dl)), without acute myocardial infarction (creatine kinase-MB (CK-MB): < 4 U/l (reference range < 25 U/l)). This evidence concerns the gene NPPB and acute myocardial infarction.
