Bilateral forearm blood flow and plasma fibrinolytic factors were assessed with venous occlusion plethysmography and blood sampling during intra-arterial infusion of acetylcholine, bradykinin, sodium nitroprusside, and verapamil. Ex vivo thrombus formation was determined with the use of the Badimon chamber. Compared with filtered air, diesel exhaust inhalation was associated with reduced vasodilatation and increased ex vivo thrombus formation under both low- and high-shear conditions. The particle trap markedly reduced diesel exhaust particulate number (from 150 000 to 300 000\/cm\n              <jats:sup>3<\/jats:sup>\n              to 30 to 300\/cm\n              <jats:sup>3<\/jats:sup>\n              ;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001) and mass (320\u00b110 to 7.2\u00b12.0 \u03bcg\/m\n              <jats:sup>3<\/jats:sup>\n              ;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001), and was associated with increased vasodilatation, reduced thrombus formation, and an increase in tissue-type plasminogen activator release.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Exhaust particle traps are a highly efficient method of reducing particle emissions from diesel engines. With a range of surrogate measures, the use of a particle trap prevents several adverse cardiovascular effects of exhaust inhalation in men. Given these beneficial effects on biomarkers of cardiovascular health, the widespread use of particle traps on diesel-powered vehicles may have substantial public health benefits and reduce the burden of cardiovascular disease.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Clinical Trial Registration\u2014<\/jats:title>\n            <jats:p>\n              <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"http:\/\/www.clinicaltrials.gov\">http:\/\/www.clinicaltrials.gov<\/jats:ext-link>\n              .
