Abstract:
Objective: To explore early diagnostic value of combined detection of ischemia-modified albumin and other biochemical markers for acute coronary syndrome (ACS). Methods: A total of 156 patients, who received treatment within 4h because of chest pain onset, were divided into ACS group (n=112) and non-ischemic chest pain group (NICP group, n=44) according to coronary angiography (CAG). Blood sample was taken within 4h and during 4~8h after chest pain to measure cardiac biochemical markers, including ischemia-modified albumin (IMA), LDH, CK, CK-MB and cardiac troponin I (cTnI), comprehensive analysis was performed by detected results of above biochemical markers and CAG. Results: For diagnosis of ACS, within 4h after onset IMA possessed highest sensitivity (87.50%) and highest accuracy (80.77%), cTnI possessed highest specificity (95.45%); In 4~8h IMA still possessed highest sensitivity (91.07%), cTnI still possessed highest specificity(97.73%), CK(85.90%),and IMA(85.25%)possessed highest accuracy (both CK and IMA had no significant difference); According to comprehensive analysis, regardless of within 4h or during 4~8h after chest pain, IMA possessed highest sensitivity and highest accuracy, cTnI possessed highest specificity. Within 4h after chest pain, detection of IMA combined above-mentioned other four indexes increased sensitivity (89.28%), specificity (95.45%) and accuracy (91.02%)to highest level. Conclusion: For diagnosis of ACS, IMA possesses highest sensitivity and highest accuracy, cTnI possesses highest specificity; IMA combined above-mentioned other four indexes may increase sensitivity, specificity and accuracy to highest level.
