| Outline of Final Research Achievements |
We investigated whether glutamic acid could be a risk of vasospastic angina pectoris (VSAP). Ninety-two consecutive patients suspected of having VSAP. All patients were performed diagnostic coronary angiography and the intracoronary acetylcholine provocation test. Fifty-five patients were provocation test positive (VSAP group), and 37 patients were negative (Control group).
There were no significant differences between the two groups in the levels of glutamic acid. As it has been well known that smoking is one of the major risk factor of VSAP, we compared the levels of plasma glutamic acid in the non-smokers. In non-smoker patients, the levels of plasma glutamic acid in the VSAP group were significant higher than those in the control group.
Plasma glutamic acid was significantly higher in non-smoker patients with VSAP than in non-smoker control patients, suggesting that plasma glutamic acid could be a risk factor of VSAP in non-smokers and contribute to the development of VSAP.
