Objective: To examine the diagnostic performance of glycogen-phosphorylase-isoenzyme-BB (GPBB) combined with cardiac troponin I (cTnI) in acute coronary syndrome (ACS).
Design and methods: Sixty patients with chest pain were investigated; GPBB and cTnI were measured.
Results: ACS was confirmed in 31 patients; cTnI was >0.07 μg/L in 15 patients and GPBB was >10 μg/L in 6 patients. Areas under ROC curves were similar: 0.854 (cTnI+GPBB) vs. 0.843 (cTnI), p=0.728.
Conclusion: Combination of GPBB with cTnI does not improve the detection of ACS.
