Our study aims to investigate the association of urinary IPM3 and cardio-cerebrovascular diseases (CVD) in general adults. A total of 1775 participants were enrolled from the National Health and Nutrition Examination Surveys. Urinary levels of IPM3 were measured by LC/MS as exposure to isoprene. The associations between isoprene exposure and the risk of CVD were evaluated by restricted cubic splines based on multivariable logistic regression models. The prevalence of CVD was significantly higher across IPM3 quartiles. Comparing with the lowest quartile, the highest quartile was associated with 2.47-fold risk of CVD (odds ratio: 2.47, 95% confidence interval: 1.40-4.39, P = 0.002). Restricted cubic spline confirmed that the levels of urinary IPM3 were linearly associated with cardio-cerebrovascular diseases, angina and heart attack, while nonlinearly related to CHF and CAD. In conclusion, the urinary IPM3, as a long-term isoprene exposure, was associated with the presence of cardio-cerebrovascular diseases, including CHF, CAD, angina, and heart attack. © 2023.
