The Effect Of Noninvasive Ventilation On Plasma Brain Natriuretic Peptide (Bnp) And Troponin In Copd Patients With Hypercapneic Respiratory Failure

It was reported that there is relationship between high brain natriuretic peptide (BNP) levels and mortality in chronic obstructive pulmonary disease (COPD). In this study, we investigated effect of NIV to the BNP and troponin. Fifty eight cases with COPD were enrolled to this study. The patients were divided into two groups as cases receiving NIV (n:41) and cases not receiving NIV (n:17). In both groups pretreatment and posttreatment pro BNP and troponin levels were measured. Initially, in NIV group both pro-BNP (2013.95 pg/ml) and troponin (0.17 ng/ml) levels were significantly higher than those of control group (328.9 pg/ml and 0.02 ng/ml, respectively) (p0.05). In conclusion, in severe COPD acute exacerbations that develop respiratory failure, both pro-BNP and troponin levels increase significantly. This increase suggests that in COPD exacerbations, depending on severity of exacerbation right ventricle load and pulmonary hypertension may be more prominent and myocardial injury may accompany this. In COPD exacerbations, NIV treatment could safely decrease the increased pro-BNP levels without increasing the myocardial injury.
