ABSTRACT
Objective To determine the value of ischemia modified albumin,heart-type fatty acid-binding protein,B-type natri-uretic peptide and homocysteine in the risk stratification of patients with unstable angina pectoris;thus to provide an assessment for the condition of patients in clinic.Methods 135 patients with unstable angina were included in the disease group and subjected to risk stratification according to GRACE risk score software,70 cases of low-risk group,60 cases in the middle-risk group and 5 cases in the high-risk group.Another 145 healthy people were in the control group.The levels of ischemia modified albumin,heart-type fatty acid-binding protein,B-type natriuretic peptide and homocysteine were detected and compared.Results Between the control group and the disease group,significant difference of heart-type fatty acid-binding protein,B-type natriuretic peptide and homocys-teine was found (P 0.05).In the dis-ease group,the levels of ischemia modified albumin,heart-type fatty acid-binding protein and homocysteine in each risk stratification showed no significant difference(P >0.05).The level of B-type natriuretic peptide in high-risk group was higher than that in the low-risk group and in the middle-risk group and the difference was statistically significant (P 0.05 ).Conclusion The detection of heart-type fatty acid-binding protein,B-type natriuretic peptide and homocysteine possesses certain meaning in diagnosing unstable angi-na,and the level of B-type natriuretic peptide indicates the risk degree of the disease.
