Abstract:

Objective To find serum metabolins predicting acute myocardial infarction (AMI)patients' outcome,using the metabolomics platform of ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) when patients are admitted to hospital. Methods UPLC-MS/MS platform was used to analyze 48 healthy subjects(healthy control group),48 angina patients,24 AMI patients with improvement and 24 AMI dead patients. The disease distinguishing model was established. Receiver operating characteristic(ROC) curve was used to evaluate the clinical diagnostic performance of characteristic metabolins. Results A "Normal-Angina-AMI improved-AMI dead" of the principal component analysis(PCA)(R2X=40.2%, Q2=13.9%)and orthogonal partial least-square discrimination analysis (OPLS-DA) model (R2X=79.0%, R2Y=83.2%, Q2=65.0%) were established. Through verifying,the model prediction accuracy reached 100%. Totally,10 kinds of ions that can estimate the prognosis of AMI were screened and verified. 4-Hydroxy-6-docosanone,N-acetyl-leukotriene,lysophosphatldy choline(LPC)[18: 2(9Z,12Z)],LPC(18:0),LPC(P-16:0),LPC[P-18:1(9Z)],LPC[20:1(11Z)],LPC[20:2(11Z,14Z)] decreased,and L-threonine and 3-methyl-2-butene-1-thiol increased. There was statistical significance between AMI patients with improvement and AMI dead patients(P<0.05). Conclusions Specific metabolins can effectively predict the prognosis of patients with AMI. These ions may be potential prognosis biomarkers and have benefit in further clinical study.
