BACKGROUND: Noise from wind turbines (WTs) is reported as more annoying than traffic noise at similar levels, raising concerns as to whether WT noise (WTN) increases risk for cardiovascular disease, as observed for traffic noise. OBJECTIVES: We aimed to investigate whether long-term exposure to WTN increases risk of myocardial infarction (MI) and stroke. METHODS: We identified all Danish dwellings within a radius 20 times the height of the closest WT and 25% of the dwellings within [Formula: see text] the height of the closest WT. Using data on WT type and simulated hourly wind at each WT, we estimated hourly outdoor and low frequency (LF) indoor WTN for each dwelling and derived 1-y and 5-y running nighttime averages. We used hospital and mortality registries to identify all incident cases of MI ([Formula: see text]) and stroke ([Formula: see text]) among all adults age 25-85 y ([Formula: see text]), who lived in one of these dwellings for [Formula: see text] over the period 1982-2013. We used Poisson regression to estimate incidence rate ratios (IRRs) adjusted for individual- and area-level covariates. RESULTS: IRRs for MI in association with 5-y nighttime outdoor WTN [Formula: see text] (vs. [Formula: see text]) dB(A) and indoor LF WTN [Formula: see text] (vs. [Formula: see text]) dB(A) were 1.21 [95% confidence interval (CI): 0.91, 1.62; 47 exposed cases] and 1.29 (95% CI: 0.73, 2.28; 12 exposed cases), respectively. IRRs for intermediate categories of outdoor WTN [24-30, 30-36, and [Formula: see text] vs. [Formula: see text]] were slightly above the null and of similar size: 1.08 (95% CI: 1.04, 1.12), 1.07 (95% CI: 1.00, 1.12), and 1.06 (95% CI: 0.93, 1.22), respectively. For stroke, IRRs for the second and third outdoor exposure groups were similar to those for MI, but near or below the null for higher exposures. CONCLUSIONS: We did not find convincing evidence of associations between WTN and MI or stroke. https://doi.org/10.1289/EHP3340.
