The relationship of cigarette smoking with inflammation and subclinical vascular disease: The Multi-Ethnic Study of Atherosclerosis.
By: McEvoy J, Nasir K, DeFilippis A, Lima J, Bluemke D, Hundley WG, Barr RG, Budoff M, Szklo M, Navas-Acien A, Polak J, Blumenthal R, Post W, Blaha M.

We sought to assess the impact of smoking status, cumulative pack-years, and time since cessation (the latter in former smokers only) on 3 important domains of cardiovascular disease: inflammation, vascular dynamics and function, and subclinical atherosclerosis. These findings expand our understanding of the harmful effects of smoking and help explain the cardiovascular benefits of smoking cessation.

25-Hydroxyvitamin D and parathyroid hormone are not associated with carotid intima-media thickness or plaque in the multi-ethnic study of atherosclerosis.
By: Blondon M, Sachs M, Hoofnagle AN, Ix JH, Michos ED, Korcarz C, Gepner AD, Siscovick DS, Kaufman JD, Stein JH, Kestenbaum B, de Boer IH.
The consistent lack of association of vitamin D and parathyroid hormone with carotid intima-media thickness and plaque suggests that these hormones may influence cardiovascular risk through pathways not reflected by carotid atherosclerosis.

The ABCG8 G574R variant, serum plant sterol levels, and cardiovascular disease risk in the Old Order Amish.
By: Horenstein RB, Mitchell BD, Post WS, Lütjohann D, von Bergmann K, Ryan KA, Terrin M, Shuldiner AR, Steinle NI.

Although the G574R variant is associated with moderately elevated plant sterol levels, carriers of the 574R allele had modestly lower levels of carotid wall thickness compared with noncarriers.

Association of SRB1 variants with subclinical atherosclerosis and incident cardiovascular disease: The Multi-Ethnic Study of Atherosclerosis.
By: Manichaikul A, Naj AC, Herrington D, Post W, Rich SS, Rodriguez A.

We previously reported a statistically significant association of SCARB1 intronic single nucleotide polymorphism (SNP) rs10846744 with common carotid intimal-medial artery thickness in each of the 4 Multi-Ethnic Study of Atherosclerosis racial/ethnic groups (white, Chinese, black, and Hispanic). The SCARB1 SNP, rs10846744, exerts a major effect on subclinical atherosclerosis and incident cardiovascular disease in humans.

Hepatic steatosis, obesity, and the metabolic syndrome are independently and additively associated with increased systemic inflammation.
By: Ndumele CE, Nasir K, Conceiçao RD, Carvalho JA, Blumenthal RS, Santos RD.
The goal of this study was to assess the independent and collective associations of hepatic steatosis, obesity, and the metabolic syndrome with elevated hsCRP levels. We evaluated 2,388 individuals without clinical cardiovascular disease between December 2004 and December 2006. Hepatic steatosis was diagnosed by ultrasound, and the metabolic syndrome was defined using National Heart, Lung, and Blood Institute criteria. We concluded that hepatic steatosis, obesity, and the metabolic syndrome are independently and additively associated with increased odds of high hsCRP levels.

Association between obesity, high-sensitivity C-reactive protein greater than or equal to 2 mg/L, and subclinical atherosclerosis: implications of JUPITER from the Multi-Ethnic Study of Atherosclerosis.
By: Blaha MJ, Rivera JJ, Budoff MJ, Blankstein R, Agatston A, O’Leary DH, Cushman M, Lakoski S, Criqui MH, Szklo M, Blumenthal RS, Nasir K.

Levels of hsCRP are closely associated with abdominal obesity, metabolic syndrome, and atherosclerotic cardiovascular disease. The JUPITER trial has encouraged using hsCRP greater than or equal to 2 mg/L to guide statin therapy; however, the association of hsCRP and atherosclerosis, independent of obesity, remains unknown. We concluded that high hsCRP, as defined by JUPITER, was not associated with CAC and was mildly associated with carotid intima-media thickness (cIMT) in the absence of obesity. In contrast, obesity was associated with both measures of subclinical atherosclerosis independently of hsCRP status.

Association of the vitamin D metabolism gene CYP24A1 with coronary artery calcification.
By: Shen H, Bielak LF, Ferguson JF, Streeten EA, Yerges-Armstrong LM, Liu J, Post W, O’Connell JR, Hixson JE, Kardia SL, Sun YV, Jhun MA, Wang X, Mehta NN, Li M, Koller DL, Hakonarson H, Keating BJ, Rader DJ, Shuldiner AR, Peyser PA, Reilly MP, Mitchell BD.
The vitamin D endocrine system is essential for calcium homeostasis, and low levels of vitamin D metabolites have been associated with CVD risk. We hypothesized that DNA sequence variation in genes regulating vitamin D metabolism and signaling pathways might influence variation in CAC. A common SNP in the CYP24A1 gene was associated with CAC quantity in 3 independent populations. This result suggests a role for vitamin D metabolism in the development of CAC quantity.

Risk factor differences for aortic versus coronary calcified atherosclerosis: the multi-ethnic study of atherosclerosis.
By: Criqui MH, Kamineni A, Allison MA, Ix JH, Carr JJ, Cushman M, Detrano R, Post W, Wong ND.
The goal of this study was to compare and contrast CAC with abdominal aortic calcium (AAC) in terms of their associations with traditional and novel CVD risk factors. AAC showed stronger correlations with most CVD risk factors than did CAC. The predictive value of AAC compared with CAC for incident CVD events remains to be evaluated.
