ABSTRACT
Objective To explore the relationship between different blood glucose levels and new carotid artery plaques.Methods A total of 5 440 participants met the inclusion criteria were selected stratified randomly from the 101,510 serving and retired workers of Tangshan Kailuan Company who participated the health examination from 2006 to 2007.The follow-up health examination were respectively preformed from 2010 to 2011 and from 2012 to 2013 which included carotid ultrasound for these 5 440 participants.The 5 440 participants were divided into three groups (ideal blood glucose group,impaired fasting glucose group and diabetic group) according to their fasting glucose levels in 2010-2011 examination.Multivariate Logistic regression analysis was used to analyze the risk factors of new carotid artery plaques.Results Among 5 440 subjects,participants whose FPG,ultrasound data incomplete and ultrasound detection of carotid plaques during the 2010-2011 health examination were excluded,then 3 084 participants were included in this study,among them,175 participants who did not participate the 2012-2013 health examination and 561 participants whose carotid plaque ultrasound data incomplete were excluded.Thus,a total of 2 348 participants were included in the present analysis.The total detection of new carotid artery plaque rate was 15.0％ (352/2 348) after 2 years of follow-up.The detection of new carotid artery plaque rate in normal glucose group(n =1724),impaired fasting glucose group(n=464) and diabetic group(n=160) were 14.2％(245/1 724),14.9％(69/464) and 23.8％(38/160),respectively.The diabetic group was higher than that of the ideal blood glucose group and the impaired fasting glucose group,the difference was statistically significant(P＜0.05).Impaired fasting glucose group and diabetic group had an increased risk of new carotid artery plaque compared with those in ideal glucose group(OR =0.924,95％CI 0.691-1.235 and OR =1.733,95％CI 1.107-2.713,respectively),the difference was statistically significant(P＜0.05).After adjusted for the other risk factors,with the risk-adjusted ratio (OR =1.117,95％CI 0.824-1.513 and OR =1.393,95％CI 0.872-2.226).Conclusion The detection of new carotid artery plaque increase in the diabetic group.However,after adjustment for other risk factors associate with emerging danger of new carotid artery plaque is no significant difference.This requires more long-term follow-up study of a large sample to be further confirmed.
ABSTRACT
Objective To investigate the correlation of the 24?hour ambulatory systolic blood pressure (SBP) and carotid intima?media thickness(CIMT) in the elderly. Methods A total of 2 464 who were more than or equal to 60 years old participants were selected with random sampling in accordance with the inclusion criteria from the retired workers in Tangshan Kailuan Company. Dynamic blood pressure monitoring, neck vascular ultrasound and other examination were performed for the participants. . Multivariable linear regression analysis was used to analyze correlation between the SBP of 24?hour, daytime and nightime with CIMT, respectively. Results ( 1) The observation population was divided into three groups according to the tertiles of SBP of 24?hour, daytime and nightime, respectively. With the levels of different SBPs inceasing, CIMT values thickened markedly ( P<0. 01 ) . ( 2 ) Multivariable linear regression analysis showed that after adjusting for confounding factors,the SBP of 24?hour,daytime and nightime associated with CIMT positively and linearly(P<0. 05),and regression coefficient(95%CI) were 0. 022(0. 009-0. 035), 0. 021(0. 008-0. 035), 0. 019 ( 0. 006-0. 032) respectively. In addition,clinic SBP step into the multivariable linear regression,and regression coefficient ( 95%CI ) were 0. 016 ( 0. 003-0. 029 ) , 0. 016 ( 0. 003-0. 030 ) , 0. 019 ( 0. 007-0. 032 ) , respectively. Conclusion The effect of increased 24?hour ambulatory SBP on CIMT was greater than the clinic SBP. Active monitoring of 24 h ambulatory blood pressure and maintaining a low level of blood pressure is essential for preventing and delaying atherosclerosis.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the impact of ideal health behaviors on the newly developed carotid plaques.</p><p><b>METHODS</b>A total of 5 852 employees (including retired employees from Tangshan Kailuan company) aged over 40 years were included in this study through stratified random sampling. Subjects with previous stroke, transient ischemic attack, myocardial infarction were excluded. Results from the unified questionnaire, blood biochemistry measurements and ultrasonography carotid artery measurements were analyzed. Present study analyzed the data from 2 372 participants without carotid plaques in 2010-2011 examinations. The newly developed carotid plaques in 2012-2013 health examinations were observed and multiple logistic regression analysis was used to explore the impact of ideal health behaviors and factors on the newly developed carotid plaques.</p><p><b>RESULTS</b>(1) There were 359 subjects with newly developed carotid artery plaques among the 2 372 subjects (15.1%), prevalence rate was 23.1% (43/186), 17.5% (186/1 065), 12.4% (122/986), 5.9% (8/135) in the groups with 0-1, 2-3, 4-5 and 6-7 components of ideal cardiovascular health behaviors and factors, respectively (P < 0.001). (2) Multiple logistic regression analysis showed that after adjusting for age, gender, high density lipoprotein cholesterol, heart rate, and high sensitive c-reactive protein, compared to with 0-1 components of ideal cardiovascular health behaviors and factors, participants with 4-5 and 6-7 components of ideal cardiovascular health behaviors and factors were associated with reduced risk of the newly developed carotid plaques, the OR (95% CI) values were 0.52(0.34-0.80) and 0.28(0.12-0.64), respectively.</p><p><b>CONCLUSION</b>Higher number of ideal cardiovascular health behaviors and factors is associated with lower incidence of newly developed carotid plaques.</p>
