Background The over increase of sympathetic drive in chronic heart failure （CHF） is with main responsibility for the deterioration and mortality of the *** 123I-metaiodobenzylganidine （MIBG） scintigraphy is a non-invasive convenient method to assess sympathetic dysfunction in patients with *** aim of the study was to detect if sympathetic antidrive analysed through myocardial MIBG scintigraphy plays a crucial role in long-term prognosis in *** Sixty-four enrolled patients underwent myocardial MIBG scintigraphy, and their plasma concentration of brain natriuretic peptide （BNP）, myocardial contractile reserve （MCR）, rest left ventricular ejection fraction （rest LVEF）and New York Heart Association （NYHA） function class were *** were separated into groups according to median of above *** was cardiac death and it was recorded in each group during average 54 months＇ *** At the end of follow-up, group with lower ratio of heart/mediastinum （H/M） had more death events （P=0.001）,and its BNP level was higher and MCR level was lower （P=0.003 and 0.001, respectively）; but its rest LVEF and NYHA function class were not significantly different.H/M, MCR and BNP correlated closely with death （P=0.000, 0.000 and 0.001, respectively）.Among the three indicators the death risk ratio （RR） of H/M was 4.66, more than MCR and BNP （1.88 and 2.56, respectively）.However, rest LVEF and NYHA function class did not correlate with death （P=0.652 and 0.384, respectively）.The group with lower H/M and MCR, higher BNP had much more death than that with higher H/M and MCR, lower BNP, the RR being *** Myocardial MIBG scintigraphy is a long-term prognostic marker in ***, MCR are also excellent predictors of long-term prognosis in CHF, but not stronger than myocardial MIBG *** the three indicators were joined together, the prediction would become most *** LVEF and NYHA have no significance in long-ter
