Relationship Between Serum Eicosapentaenoic Acid Levels and J-Waves in a General Population in Japan.

Relationship Between Serum Eicosapentaenoic Acid Levels and J-Waves in a General Population in Japan. Int Heart J. 2018 Jun 06;: Authors: Kimura Y, Yamada M, Hanada K, Endo T, Narita N, Narita M, Senoo M, Yonekura M, Ichikawa H, Kurauchi S, Nakaji S, Okumura K, Tomita H Abstract We previously showed that J-waves were found more frequently in patients with low levels of serum eicosapentaenoic acid (EPA) in the acute phase of myocardial infarction, and were associated with the incidence of ischemia-related ventricular arrhythmias. However, the relationship between J-waves and serum EPA levels in a general population remains to be elucidated.The Iwaki Health Promotion Project is an ongoing community-based health promotion study in Iwaki, Hirosaki, which is in northern Japan. A total of 1,052 residents (mean age, 53.9 ± 15.4 years; 390 men) who participated in this project in 2014 were studied. A standard 12-lead electrocardiogram (ECG) was recorded and serum EPA levels were measured to evaluate the relationship between J-waves and serum EPA levels. J-waves were found in 52 (5%) subjects and were observed more frequently in male than female subjects (44 [11%] versus 8 [1%], P < 0.0001). More than half of the J-waves were the notched type (60%), and J-waves were detected most frequently in inferior leads on ECG (52%). The RR interval was longer and QTc duration shorter in subjects with J-waves than those without. No significant differ...
