Outline of Final Research Achievements |
This study was to clarify the relationship between glycemic fluctuations and unsaturated fatty acids in coronary spastic angina. The relationship between glycemic fluctuations and coronary spastic angina could not be clarified due to the small number of cases. We reported at the Japanese Circulation Society that the omega-3 unsaturated fatty acid DHA, which predominates parasympathetic nerves, affects the development of coronary spastic angina. We also reported the relationship between unsaturated fatty acids and coronary spastic angina at SHINZO.

Academic Significance and Societal Importance of the Research Achievements |
冠攣縮性狭心症は急性心筋梗塞や心室細動の原因となり突然死を来すため本疾患の克服は重要である。我々は血糖変動と冠攣縮性狭心症の関係は明らかにできなかったが、不飽和脂肪酸のDHAが高いと冠攣縮に影響を及ぼしていることを明らかにした。欧米人と比較し冠攣縮際狭心症は日本人に多いと考えられている。DHAは青魚に多く含まれ、副交感神経を優位にする働きがあることが報告されていることから、冠攣縮性狭心症が日本人に多いとされる原因の解明につながる可能性がある。
