Influence of left anterior descending coronary stenting on left ventricular function / 中国基层医药

ABSTRACT

Objective To study the effect of left ventricular function in the left anterior descending coronary artery stent implantation.Methods randomly 100 cases of left anterior descending coronary artery stenosis in patients with coronary heart disease branch were divided into the observation group and the control group (each group 50 cases),the control group used mainly drug treatment,the observation group used a implanted stent in the treatment of percutaneous left anterior descending coronary artery.the left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD,left ventricular ejection fraction(LVEF) and serum N terminal pro-brain natriuretic peptide(NT-proBNP) levels were observed between two groups.Results after treatment,6 months,two groups of LVEDD,LVESD and NT-proBNP compared with those before treatment were significantly lower(t =2.75,3.14,3.54,all P ＜0.05),while LVEF increased significantly (t =12.45,P ＜ 0.05);and compared with the control group,LVEDD,LVESD of the observation group decreased significantly,LVEF increased significantly(t =2.27,3.75,2.21,all P ＜ 0.05).Conclusion The left anterior descending coronary artery stent implantation in treatment can effectively improve left ventricular function in patients with coronary heart disease.
