Influence of transcatheter closure combined drug intervention on BNP and vascular vascular endotheli-um levels in children with CHD complicated pulmonary artery hypertension / 心血管康复医学杂志

ABSTRACT

Objective:To study the influence of transcatheter closure combined drug intervention on levels of brain na-triuretic peptide (BNP)and vascular endothelium (ET)in children with congenital heart disease (CHD)complicated pulmonary artery hypertension (PAH).Methods:A total of 70 CHD + PAH children from Mar 2011 to May 2013 in our hospital were enrolled.According to random number table,they were equally divided into transcatheter clo-sure combined drug intervention group (combined treatment group)and transcatheter closure control group (only re-ceived transcatheter closure therapy).Cytokine levels and heart function indexes were observed and compared be-tween two groups.Results:Compared with transcatheter closure control group after treatment,there were signifi-cant reductions in levels of BNP [(352.7±56.2)ng/L vs.(194.5±25.2)ng/L]and vascular ET [(68.4±8.4)ng/L vs.(37.5±5.2)ng/L,P <0.01],and significant rise in left ventricular early diastolic peak filling velocity [E, (63.7±6.9)cm/s vs.(71.7±7.4)cm/s],left ventricular early/late diastolic peak filling velocity [E/A,(1.10± 0.13)vs.(1.34±0.16)],left ventricular ejection fraction [LVEF,(62.3±7.6)% vs.(66.4±7.1)%]and left ventricular end-diastolic diameter [LVEDd,(48.9±5.7)mm vs.(54.1±5.8)mm]in combined treatment group, P <0.05 or <0.01.Conclusion:Transcatheter closure combined drug intervention can reduce BNP and vascular ET concentrations,improve heart function,which possesses positive clinical application value.
