Abstract:
Objective To study the change of mid-regional pro-adrenomedullin(MR-proADM) level in patients with chronic heart failure and its significance.Methods Randomly selected 330 patients with chronic heart failure,including 120 cases of grade Ⅱ and Ⅲ,90 cases of grade Ⅳ,90 cases were selected.,Within 24 h after the entry of the group and 7 d after symptom relieved,serum N-terminal pro-B-type natriuretic peptide(NT-proBNP),MR-proADM,cardiac ultrasound(left ventricular diameter(LVEDD) and left ventricular function(LVEF)) were measured.Ninety physical examination in the same period as healthy control during the same period.The change of MR-proADM level in patients with chronic heart failure and its significance were analyze.Results Compared with the healthy control group,the level of MR-proADM in patients with chronic heart failure(grade Ⅱ:(641.55±106.34) pmol/l;grade Ⅲ:(684.46±101.33) pmol/l;grade Ⅳ:(737.81±479.37) pmol/l) was significantly higher than that in the control group(610.22±60.84) pmol/l),the difference was statistically significant(F=5.33,P=0.001).At the same time,the level of MR-proADM was increased with the aggravation of heart failure,after drug treatment will decline((608.09±100.81),(617.64±94.32),(642.22±163.53) pmol/L).And MR-proADM levels were significantly positively correlated with NT-proBNP levels and NYHA classification in patients with heart failure(r=0.194,P=0.003;r=0.206,P=0.000).Conclusion MR-proADM has important guiding significance in the diagnosis,classification of patients with chronic heart failure.
