Abstract:
Objective To investigate the association betweent clinical markers of N‐terminal probrain natriuretie peptide (NT‐proBNP) ,cardiac troponin I (cTnI) and C‐reaction protein (CRP) in the patients with acute respiratory distress syndrome (ARDS) caused by severe pneumonia and to reveal the pathophysiologic process of myocardial injury after ARDS .Methods Totally 33 patients diagnosed as ARDS caused by severe pneumonia were divided into 3 groups:mild group ,moderate group and severe group according to the New Berlin definition of ARDS .Arterial blood gas analysis ,NT‐proBNP ,cTnI and CRP were observed be‐fore the treatment .Statistics were used for the analyses .Results The NT‐proBNP level in the severe group was significantly higher than that in the mild and moderate groups (P<0 .01);the NT‐proBNP level in the moderate group was also higher than that in the mild group (P< 0 .05) .Besides ,the cTnI level in the severe group was significantly higher than that in the mild and moderate groups (P<0 .01);however ,the cTnI level had no statistical difference between mild and moderate groups (P> 0 .05) .The CRP level in the severe group was significantly higher than that in the mild (P<0 .05) .Moreover ,the NT‐proBNP level of 33 patients was positively associated with the both CRP and cTnI level (P<0 .05) .Conclusion The seriously inflammatory response mediates myocardial injury probably because of ARDS .Combined NT‐proBNP and cTnI testing is important for evaluating the condition of ARDS at the early stage .
