The World Health Organization (WHO) and various studies have established associations between transportation noise and cardiovascular disease (CVD), such as myocardial infarction, stroke, heart failure, and arrhythmia. The WHO Environmental Noise Guidelines and recent reviews confirm a heightened risk of cardiovascular incidents with increasing transportation noise levels. We present a narrative review of the evidence from epidemiologic studies and translation studies on the adverse cardiovascular effects of transportation noise. We describe the results of a recent Umbrella+ review that combines the evidence used in the 2018 WHO Environmental Noise Guidelines with more recent (post-2015) high-quality systematic reviews of original studies. High-quality systematic reviews were included based on the quality of literature search, risk of bias assessment, and meta-analysis methodology using AMSTAR 2. Epidemiologic studies show that exposure to high levels of road traffic noise for several years lead to numerous adverse health outcomes, including premature deaths, ischemic heart disease (IHD), chronic sleep disturbances, and increased annoyance. Mechanistically, noise exposure triggers oxidative stress, inflammation, endothelial dysfunction, and circadian rhythm disruptions. These processes involve the activation of NADPH oxidase, mitochondrial dysfunction, and nitric oxide synthase uncoupling, leading to vascular and cardiac damage. Studies indicate that chronic noise exposure does not result in habituation, and susceptible individuals, such as those with pre-existing CVD, are particularly vulnerable.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"35 1","pages":"24-33"},"PeriodicalIF":4.1,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41370-024-00732-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although these factors frequently coexist, their combined impact and the underlying pathophysiological mechanisms remain poorly understood. This study aimed to evaluate the joint effects of high transportation noise exposure and lower SES on major adverse cardiovascular events (MACE) and the role of the neural-arterial axis in mediating this relationship. We retrospectively analyzed data from 507 individuals who underwent clinical 18F-FDG-PET/CT imaging at a single center. SES was evaluated using local median income (as a primary measure) and area deprivation index (ADI, as a secondary measure). Participants were classified into three groups based on transportation noise exposure and income/ADI: low noise/higher SES, high noise or lower SES, and high noise/lower SES. Cox models assessed MACE risks. Linear regression models evaluated associations with stress-related neural activity (SNA) and arterial inflammation (ArtI). The combination of high noise exposure and low income (vs. neither exposure) associated with increased MACE risk (HR [95% CI]: 5.597 [2.201–14.233], p &lt; 0.001). SNA (standardized β [95% CI]: 0.389 [0.192–0.586], p &lt; 0.001) and ArtI (0.151 [0.005–0.298], p = 0.043) were greater in this group. Mediation analysis showed that the neural-arterial axis contributes to increased exposure-related MACE risk and accounts for 8% of the overall effect. Similar results were found with ADI. Our study uniquely demonstrates how combined high transportation noise and lower socioeconomic status additively increases cardiovascular disease risk through specific biological pathways, particularly via effects on stress-associated neural activity and arterial inflammation. As such, the research offers novel insights into the interplay between environmental and socioeconomic factors in cardiovascular health. This underscores an urgent need for integrated public health strategies that address both noise pollution and socioeconomic disparities and provides a foundation for targeted interventions aimed at reducing the burden of cardiovascular disease in vulnerable populations.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"35 1","pages":"62-69"},"PeriodicalIF":4.1,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142693032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
