Association between air pollution and coronary artery calcification within six metropolitan areas in the USA (the Multi-Ethnic Study of Atherosclerosis and Air Pollution): a longitudinal cohort study (Abstract, 1 page pdf, Joel D Kaufman, Sara D Adar, R Graham Barr,  Matthew Budoff, Gregory L Burke, Cynthia L Curl,  Martha L Daviglus,  Ana V Diez Roux, Amanda J Gassett,  David R Jacobs Jr, Prof Richard Kronmal, Timothy V Larson, Ana Navas-Acien, Casey Olives, Paul D Sampson, Lianne Sheppard, David S Siscovick,  James H Stein, Adam A Szpiro,  Karol E Watson, The Lancet, May 24, 2016

Today we review research conducted over a decade on the biological impacts of  traffic-related air pollution (PM2.5 and NOx)  on the arteries which in turn results in a higher risk of heart attack.. Results indicate  coronary calcium increased with increases in PM2.5 by 4.1 Agaston units/yr and in NOx by 4.8 Agaston units/yr. The authors suggest that increases in traffic related pollution especially in urban areas world-wide can be associated with increased cardiovascular diseases.
