Abstract:
A combined full-scan mass spectrometry/data-dependent acquisition(Full MS/ddMS2)and full-scan mass spectrometry/parallel reaction monitoring(Full MS/PRM)approach for qualitative and quantitative analysis of plasma acylcarnitines was established on the basis of ultra-performance liquid chromatography-high resolution mass spectrometry(UPLC-HRMS).A total of 165 kinds of acylcarnitines were identified,and 111 kinds of acylcarnitines were quantified.The method demonstrated good reproducibility,with a relative standard deviation of less than 20%for plasma acylcarnitine content.Statistical analyses,including t-tests,partial least squares-discriminant analysis,variable importance in projection and volcano plot analysis,indicated significant alterations in plasma acylcarnitine levels in heart failure patients after myocardial infarction,for instance,46 kinds of acylcarnitines showing marked increases compared to myocardial infarction patients.Acylcarnitines showed a strong positive correlation with the clinical biomarker NT-proBNP,which was associated with heart failure.The combined use of acylcarnitine markers AC(C14-OH),AC(C12:1a),long-chain acylcarnitines,total acylcarnitines and NT-proBNP significantly enhanced the diagnostic sensitivity and specificity for post-infarction heart failure,with the area under the receiver operating characteristic curve(AUC)reaching 0.9456.The results of this work indicated that acylcarnitine was poised to become a crucial metabolic target for precise diagnosis,treatment and nutritional intervention in the progression of heart failure after myocardial infarction.
