A comparison between C-reactive protein,adrenomedullin and endothelin-1 in patients of chronic congestive heart failure / 中国基层医药

ABSTRACT

Objective To study the changes of cytokine activation in patients with chronic congestive haert failure(CHF) as indicated by plasma levels of C-reactive protein(CRP)and its relation to adrenomedullin(ADM) and endthelin-1(ET-1).Methods The plasma levels of CRP,ADM and ET-1 of 60 decompensated haert failure(DHF) patients group and 30 essential hypertension patients with compensated cardiac function(CCF) group were tested. CRP was determined by immunoturbidometry,ET-1 and ADM were determined by radioimmunoassay.Results The plasma levels of ET-1 ,ADM and CRP of decompensated heart failure group were significantly higher than the compensated cardiac function group;In the decompensated heart failure group,the plasma levels of CRP and ADM were elevated according to worsening of heart failure(NYHA classification) ;In the decompensated heart failure group,the plasma levels of CRP were positively correlated with ADM(r=0.57).Conclusion There is extensive activation of cytokines,ADM and ET-1 in patients with chronic congestive heart failure.Cytokine activation might play a role in the synthesis of ADM,thus contribute to the hum oral regulation of heart failure,but may not be re- sponsible for the activation of ET-1.
