Relationship between Serum GGT,CysC,ApoB/ApoA1 Ratio and Prognosis of Patients with Acute ST Elevation Myocardial Infarction Complicated with Type 2 Diabetes Mellitus
Objective:To investigate the relationship between serum γ-glutamyl transferase(GGT),cystatin C(CysC),apolipopro-tein B/apolipoprotein A1(ApoB/ApoA1)ratio and the prognosis of patients with acute ST elevation myocardial infarction(ASTEMI)complicated with type 2 diabetes mellitus(T2DM).Methods:The clinical data of 175 patients with ASTEMI complicated with T2DM who underwent percutaneous coronary intervention(PCI)in Guangdong Provincial Hospital of Traditional Chinese Medicine were retro-spectively collected,patients were divided into poor prognosis group(63 cases)and good prognosis group(112 cases)according to the prognosis at 1 month after PCI,Serum GGT and CysC levels were detected and ApoB/ApoA1 ratio was calculated.The factors affecting the poor prognosis of ASTEMI patients complicated with T2DM after PCI were analyzed by multivariate Logistic regression,the predic-tive value of serum GGT,CysC and ApoB/ApoA1 ratio for the poor prognosis of ASTEMI patients complicated with T2DM after PCI were analyzed by receiver operating characteristic curve(ROC).Results:1 month after follow-up,the incidence of poor prognosis after PCI in 175 ASTEMI patients complicated with T2 DM was 36.00%(63/175).Compared with good prognosis group,the serum GGT,CysC and ApoB/ApoA1 ratio in poor prognosis group increased(P<0.05).Killip grade≥Ⅱ and elevated serum GGT,CysC,ApoB ApoA1 ratio were independent risk factors for poor prognosis in ASTEMI patients complicated with T2 DM after PCI(P<0.05).The area under the curve(AUC)of serum GGT,CysC and ApoB/ApoA 1 ratio combined to predict the poor prognosis of ASTEMI patients complicated with T2DM after PCI was 0.924,which was greater than the 0.776,0.778 and 0.785 predicted by serum GGT,CysC and ApoB/ApoA1 ratio alone.Conclusion:Elevated serum GGT,CysC and ApoB/ApoA1 ratio are relate to the poor prognosis of ASTEMI patients compli-cated with T2DM after PCI,and the combined detection of serum GGT,CysC and ApoB/ApoA1 ratio has a high predictive value for the poor prognosis of ASTEMI patients complicated with T2DM after PCI.
