The relationship between serum high-mobility group box-I and prognosis of coronary heart disease in old patients / 中华老年医学杂志

ABSTRACT

Objective To investigate the correlation of serum high-mobility group box-1 (HMG-B1) with the severity of lesion of coronary artery disease (CAD) and its prognosis in elderly patients.Methods A total of 180 CAD patients with coronary stenosis exceeding 50 percent by coronary angiography were divided into three groupsone branch stenosis;two branches stenosis and three branches stenosis.The control group included 50 patients without coronary stenosis.The degrees of coronary stenosis were diagnosed as mild stenosis,moderate stenosis and severe stenosis based on improved Gensini scores.The severity of decrements of left ventricular ejection fraction (LVEF) by echocardiogram were divided into three groupsmild,moderate and severe LVEF.Levels of HMGB1,hs-CRP and glucose were measured in all the patients.According to whether there was a complication of type 2 diabetic mellitus (T2DM),the 180 patients were classified as two groups.The patients were also divided into two groups according to whether there were adverse events.Results The HMGB1 levels of the CAD group were increased along with the number of affected vessels [three bunch group (40.5±6.0) ng/ml,double bunch group (33.1±4.9)μg/L,single bunch group (20.5±3.3)μg/L and control group (6.2±1.4)μg/L (all P＜0.05)].And the HMGB1 levels of the CAD group were increased along with the degrees of CAD stenosis [severe stenosis group (43.0±5.8)μg/L,medium stenosis group (32.1±4.5)μg/L,mild stenosis group(19.3±2.0)μg/L] (all P＜0.05).Meanwhile,the levels of HMGB1 were increased along with the decrement of left ventricular ejection fraction [left ventricular severe dysfunction group (41.0 ± 5.5) μg/L,medium dysfunction group(33.1± 4.3)μg/L,mild dysfunction group (21.3± 2.0)μg/L] (all P＜0.05).CAD with T2DM had a higher HMGB1 level than non-T2DM group[(35.7±5.0) (C)/L vs.(23.3±3.0) (C)/L,P＜0.05].The adverse events group had a higher HMGB1 level than non-adverse events group[(38.7±5.5) (C)/L vs.(25.3±3.3)μg/L,P＜0.05].Besides,HMGB1 had a positive correlation with levels of hs-CRP and glucose(r=0.680,0.571,P＜0.05).Conclusions Serum HMGB1 change is closely related to morbid change degree of elderly CAD patients as well as prognosis.As a new type of inflammatory factor,HMGB1 may serve as a new target for disease treatment.
