ABSTRACT
Objective To explore the correlation among ST-2,adiponectin(APN),positive growth dif-ferentiation factor -15(GDF-15)and senile heart failure,and to investigate the diagnostic values of these indica-tors. Methods Totally 129 patients(15 patients of NYHA Ⅰ,60 of NYHA Ⅱ,28 of NYHA Ⅲ and 26 of NYHAⅣin study group)with heart failure and 30 control subjects(control group)were enrolled in the study.Se-rum levels of ST-2,APN and GDF-15 were determined by ELISA,and their correlation with senile heart failure was analyzed.Results Compared with those in control group,serum levels of ST-2,APN and GDF-15 in study group were significantly increased(P<0.05).There were significant differences in serum levels of ST-2,APN and GDF-15 among patients of different classifications in study group(P<0.05)and the higher level of cardiac func-tion,the higher serum ST-2,APN and GDF-15. There was a positive correlation among serum ST-2,APN and GDF-1. Conclusions The serum levels of ST-2,APN and GDF-1 are positively related to the severity of senile heart failure,thus it could be served as the index of diagnosis,curative effect monitoring and prognosis of patients with heart failure.
