Myocardial Metabolomics in Rats with Coronary Heart Disease and Blood Stasis Obstruction Syndrome
To explore the potential biological basis of coronary heart disease (CHD) with heart-blood stasis obstruction syndrome by using metabolomics.
Methods
2
Twenty SD rats were randomly divided into normal group (8 rats) and the heart-blood stasis obstruction syndrome group (12 rats). The model of CHD with heart-blood stasis obstruction syndrome was prepared by high-fat diet combined with vitamin D3 and subcutaneous injection of isoproterenol. The changes of cardiac histomorphology and mitochondrial ultrastructure of cardiomyocytes were observed. The myocardial tissue samples of rats were collected for metabolomics research using liquid chromatography-mass spectrometry (LC-MS). The differential metabolites between the groups were screened through principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA), and the related metabolic pathways were analyzed.
Results
2
The cardiomyocytes in the normal group were arranged orderly and the structure was clear, with regularly arranged and complete mitochondria. Cardiac myocyte hypertrophy, muscle fibers swelling, and inflammatory cell infiltration were observed in the heart blood stasis obstruction syndrome group, with decreased and disorderly arranged mitochondria in different sizes, as well as certain dissolved and ruptured mitochondria and disappeared membrane structure. The endogenous metabolites of rats in both groups were significantly different, and 19 differential metabolites were detected. The rats in the heart blood stasis obstruction syndrome group had increased expression levels of triphenyl phosphate, inosine, TrHA, taurine, pantothenic acid and propylthiouracil, as well as decreased expression of LysoPC[18∶2(9Z,12Z)], PE[18∶1(9Z)/0∶0], PE[0∶0/18∶2(9Z,12Z)], PC[18∶2(2E,4E)/0∶0], PC[18∶2(9Z,12Z)/0∶0], PC[18∶1(9Z)/0∶0], PG(16∶0/0∶0)[U], L-isoleucine, 2-hydroxycinnamic acid, DG[15:1(9Z)/18:1(9Z)/0:0][iso2], xanthine, methylamine, and L-phenylalanine Acid than those in the normal group. Multiple metabolic pathways were involved such as phenylalanine, tyrosine and tryptophan biosynthesis, aminoacyl tRNA biosynthesis, valine, leucine and isoleucine biosynthesis, taurine and taurine metabolism. The ROC results showed that the three differential metabolites including L-phenylalanine, L-isoleucine and taurine had a high predictive value for prognosis of CHD with heart blood stasis obstruction syndrome.
Conclusion
2
The myocardial metabolites of CHD rats with heart blood stasis obstruction syndrome mainly involve amino acid meta-bolism, lipid metabolism and purine metabolism. Three metabolites including L-phenylalanine, L-isoleucine and taurine, alone or in combination, are expected to be used as markers for the early diagnosis of CHD with heart and blood stasis obstruction syndrome.
