| Outline of Final Research Achievements |
Heart failure is a major cause of morbidity and mortality worldwide. However, conventional biomarkers are insufficient to detect early stage of HF and identification of more sensitive markers is an urgent task. We conducted the comprehensive quantification of water-soluble metabolites in blood of atrial septal defect (ASD) patients using a gas chromatograph-mass spectrometry. We found the mean level of 2-Aminobutyric acid (2-AB) in ASD patients was significantly higher than that in healthy volunteers, and 1 month after transcatherter closure of ASD, serum 2-AB levels in patients decreased to almost the same levels as healthy volunteers. We revealed that 2-AB was produced as the byproduct of GSH synthesis reactions. We also demonstrated that oxidative stress lead to 2-AB production. 2-AB monitoring may facilitate the early diagnosis strategy for heart failure.
