Electron beam computed tomography was employed to assess the presence and quantity of CAC (coronary artery calcium) in 441 participants (mean age, 61\u00a0years; 49% men) without prior history of CHD (coronary heart disease) or stroke, and CAC score was calculated using the method described by Agatston and co-workers [(1990) J. Am. Coll. Cardiol. 15, 827\u2013832] High-resolution ultrasound was employed to measure BAD (brachial artery diameter), FMD (flow-mediated dilatation) and NMD (nitroglycerine-mediated dilatation). CAC score and FMD were log-transformed after adding 1 to reduce skewness. Multivariable logistic and linear regression models based on generalized estimating equations were used to assess whether BAD, FMD and NMD were each independently associated with the presence and quantity of CAC after adjustment for CHD risk factors and use of statin and hypertension medication. CAC was detectable in 64% of participants. After adjustment for age and sex, FMD was not correlated (r=\u22120.06; P=0.27), BAD was positively correlated (r=0.16; P=0.004) and NMD was inversely correlated in a borderline significant manner (r=\u22120.10; P=0.084) with log(CAC+1). In multivariable logistic regression analyses, FMD was not associated, whereas higher BAD (P=0.021) and lower NMD (P=0.030) were independently associated with the presence of CAC. In multivariable linear regression analyses, higher BAD (P=0.004) and lower NMD (P=0.016), but not FMD, were independently associated with log(CAC+1). We conclude that greater diameter of the brachial artery and lower vasodilator response to nitroglycerine, but not FMD, are associated with subclinical coronary atherosclerosis.<\/jats:p>","DOI":"10.1042\/cs20060131","type":"journal-article","created":{"date-parts":[[2007,3,15]],"date-time":"2007-03-15T05:38:01Z","timestamp":1173937081000},"page":"175-182","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Brachial artery diameter and vasodilator response to nitroglycerine, but not flow-mediated dilatation, are associated with the presence and quantity of coronary artery calcium in asymptomatic adults"],"prefix":"10.1042","volume":"112","author":[{"given":"Iftikhar\u00a0J.","family":"Kullo","sequence":"first","affiliation":[{"name":"Division of Cardiovascular Diseases, Mayo Clinic and Foundation, Rochester, MN 55905, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.\u00a0Rauoof","family":"Malik","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases, Mayo Clinic and Foundation, Rochester, MN 55905, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lawrence\u00a0F.","family":"Bielak","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, University of Michigan, Ann Arbor, MI 48104-3028, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"II","given":"Patrick\u00a0F.","family":"Sheedy","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, University of Michigan, Ann Arbor, MI 48104-3028, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen\u00a0T.","family":"Turner","sequence":"additional","affiliation":[{"name":"Division of Nephrology and Hypertension, Mayo Clinic and Foundation, Rochester, MN 55905, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia\u00a0A.","family":"Peyser","sequence":"additional","affiliation":[{"name":"Department of Radiology, Mayo Clinic and Foundation, Rochester, MN 55905, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2007,1,3]]},"reference":[{"key":"2021120120404215400_B1","doi-asserted-by":"crossref","first-page":"1863","DOI":"10.1016\/S0735-1097(03)00358-9","article-title":"34th Bethesda Conference: Task force #1 \u2013 Identification of coronary heart disease risk: is there a detection gap?","volume":"41","author":"Pasternak","year":"2003","journal-title":"J.
