Abstract:
Objective To explore the clinical value of myocardial enzyme on diagnosis of cardiac insufficiency in patients with severe acute pancreatitis (SAP). Methods Fifty patients with SAP were classified as cardiac insufficiency group (n=14) and non-cardiac insufficiency group (n=36). The serum biochemical markers, such as cardiac troponin I (cTnI), myoglobin (MYO), creatine kinase, MB form (CK-MB), lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) were examined in two groups. ROC curve was used to evaluate the diagnostic sensitivity and specificity for cardiac insuffi-ciency using myocardial enzyme. The APACHEⅡscore was also calculated. The relationship between myocardial enzyme and APACHEⅡscore was analyzed in two groups. Results The levels of cTnI, LDH and AST were significantly increased in cardiac insufficiency group than those in non-cardiac insufficiency group (P<0.05). There were no significant differences in MYO and CK-MB between two groups of patients. The area under ROC curve for cTnI was 0.940, with a cut-off value of 0.07μg/L. The sensitivity and specificity of cTnI for diagnosing cardiac insufficiency in patients with SAP were 0.857 and 1.000, respectively. The area under ROC curve for LDH and AST was more than 0.7, with the low sensitivity for LDH (0.571) and the specificity for AST (0.778). The area under ROC curve for MYO and CK-MB was less than 0.7. APACHEⅡscore was positively correlated with cTnI, CK-MB and LDH (r= 0.639, 0.451 and 0.552,respectively, P<0.05). Conclusion The serum cTnI level can be used as the index for the diagnosis of cardiac insufficiency in patients with SAP, and can prefer-ably reflect the severity of SAP.
