The roles of high mobility group box1 and GRACE score in clinical prognosis of acute coronary syndrome patients undergoing selective percutaneous coronary intervention / 实用医学杂志

ABSTRACT

Objective To investigate the impact of high mobility group box1 and GRACE score on the clinical prognosis of patients with acute coronary syndrome undergoing selective percutaneous coronary intervention. Methods A total of 380 consecutive patients initially diagnosed with acute coronary syndrome undergoing selec-tive PCI between January 2014 and March 2015 were included,with 200 of them assigned into low high mobility group box1(HMGB1<445 ng/mL)and the other 180 patients into high mobility group box1(HMGB1≥445 ng/mL).The baseline characteristics and laboratory indexes were collected on admission,GRACE score were calculat-ed at admission.The difference between the high and low high mobility group box1 were analzyed and the influenc-ing factors of patients with acute coronary syndrome undergoing selective percutaneous coronary intervention were studied. The mean follow-up period was 24 months,and the clinical end points were deaths from various causes and readmission for coronary heart disease. Results There were significantly differences statistically between the groups of high and low high mobility group box1 in clinical diagnosis. lipoprotein associated phospholipase A2, GRACE score,mean platelet volume,red cell distribution width,age,and left ventricular ejection fraction(P <0.05). The correlation analysis showed that HMGB1 was significantly related to lipoprotein associated phospholi-pase A2 and GRACE score,with the correlation coefficents of 0.575,0.836,respectively(P<0.05).COX analy-sis showed that HMGB1,lipoprotein associated phospholipase A2,GRACE score had statistical significance for survival outcomes(P<0.05),and the area under the ROC curve drawn by combining the three was 0.851(95% CI 0.811 ~ 0.891,P < 0.05). Conclusion There was a good correlation between HMGB1 and GRACE score. HMGB1 is a good predictor of clinical outcomes in the patients with acute coronary syndromes undergoing elective PCI treatment.
