| Outline of Final Research Achievements |
In the myocardial Na + channel (Nav1.5), INa suppression was observed in both of the cell with the ω-3 PUFA (EPA) or ω-6 -PUFA (AA). In the long QT syndrome (LQTS) patients, the mean value of the concentration ratio of EPA and AA (EPA / AA ratio), showed a low value compared with the value of the general Japanese. In the group of 20 years of age or older with a syncope episode, EPA / AA ratio had an significant low value compared to the value of the group with no syncope episode. PUFA was found to modulate the Nav1.5 channel. The low-EPA / AA ratio raises the risk of syncope episode was considered.
