Abstract T P337: Asymmetric Dimethylarginine Is Related to the Predicted Stroke Risk in Middle-aged Japanese Men
Background: Asymmetric dimethylarginine (ADMA) has recently been investigated as a risk marker for cardio- and cerebrovascular diseases. However, it remains unclear whether ADMA levels are related to the risk of stroke in the general Japanese population.
Methods and Results: In this cross-sectional study, we examined 769 Japanese men (mean, 47 ± 5 years) who underwent health examinations. Each patient’s ADMA level and various vascular risk factors were assessed, and the predicted 10-year risk of stroke was calculated using the point-based prediction model for incident total stroke for Japanese from the Japan Public Health Center Study. In a multiple linear regression analysis, age, body mass index, estimated glomerular filtration rate, and current smoking status were significant independent determinants of the ADMA level. A significant odds ratio (OR) for high predicted stroke risk (10-year risk ≥ 5%) was noted in the highest quartile of ADMA level (OR, 2.47; 95% CI, 1.00-6.07) as compared to the lowest quartile, even after adjusting for potential confounding factors. A significant OR for high predicted stroke risk was also found for each standard-deviation increment in ADMA level (adjusted OR, 1.46; 95% CI, 1.10-1.92).
Conclusions: An elevated ADMA level was significantly associated with an increase in predicted stroke risk, suggesting that the measurement of ADMA level may be useful for identifying middle-aged Japanese men at high risk for stroke.
