Abstract:
Objective:To observe change of peripheral serum levels of soluble ST 2 (sST2 ) and copeptin in patients with chronic heart disease (CHF) ,and explore their diagnostic value for heart failure . Methods :A total of 80 CHF patients ,who hospitalized in our department of cardiology from Jun 1st ,2015 to Dec 1st ,2015 ,were selected as CHF group .Meanwhile ,another 30 patients with cardiac neurosis or arrhythmia were regarded as normal cardiac function group .According to NYHA classification ,CHF group was further divided into class II group (n= 22 ) , class III group (n=32) and class IV group (n=26) .Serum sST2 and copeptin levels were measured and compared a‐mong all groups ,and their correlation was analyzed .Results:Compared with normal cardiac function group ,there were significant rise in serum levels of sST2 [(0.27 ± 0.09) ng/ml vs .(1.18 ± 0.81) ng/ml] and copeptin [(1239.64 ± 229.98) pg/ml vs .(1987.16 ± 426.84) pg/ml] in CHF group , P< 0.01 both .Compared with class II group , there were significant rise in serum levels of sST2 [ (0.46 ± 0.17) ng/ml vs .(0.77 ± 0.18) ng/ml vs .(2.31 ± 0.29) ng/ml] and copeptin [ (1625.61 ± 522.13) pg/ml vs .(2103.15 ± 340.74) pg/ml vs .(2194.31 ± 332.97) pg/ml] in class III and class IV group ,and those of class IV group were significantly higher than those of class III group , P<0.05 or <0.01 .Pearson product‐moment correlation analysis indicated that serum sST2 level was significant posi‐tively correlated with serum copeptin level in CHF group (r=0.66 ,P=0.005) .Conclusion:Serum sST2 and copep‐tin levels are closely associated with severity of heart failure .They can be used as markers for heart failure ,which is worth extending .
