Research on the correlation between lipid accumulation product and carotid atherosclerosis in people with high risk of cardiovascular diseases
-
摘要:
目的 了解心血管病高危人群脂质蓄积指数(lipid accumulation product index, LAP)与颈动脉粥样硬化发病风险的相关性,为心血管病高危人群的干预提供科学依据。 方法 基于2015年9月―2016年6月国家心血管病高危人群早期筛查与综合干预项目,通过问卷调查、体格测量、实验室检测和颈动脉超声检查等方法,采用χ2/F检验对不同性别、不同年龄心血管病高危人群的一般情况进行分析,并将可能的混杂因素进行调整,采用多因素logistic回归分析模型探讨LAP与颈动脉粥样硬化的关系。 结果 相比于男性、>60岁人群,女性、≤60岁人群的LAP更高,差异均有统计学意义(均P < 0.001)。回归分析结果显示,LAP每增加1个标准差,颈动脉斑块的发生风险增加6%(OR=1.06, 95% CI: 1.01~1.12, P=0.026)。交互作用结果显示,相比于女性、不饮酒者,男性、饮酒人群中LAP高者发生颈动脉斑块的风险更高(交互作用均P < 0.05)。 结论 心血管病高危人群中,LAP与颈动脉斑块呈正相关,且在男性、饮酒者中正相关性更强。 Abstract:Objective To learn the correlation between the lipid accumulation product index (LAP) and the risk of carotid atherosclerosis in people with high risk of cardiovascular diseases, and provide scientific basis for intervention in people with high risk of cardiovascular diseases. Methods Based on the programme of screening and intervention subjects with high risk cardiovascular diseases in Jiangsu Province from September 2015 to June 2016, the general situation of high-risk groups of cardiovascular disease in different genders and ages was analyzed by χ2 /F test through questionnaires, physical measurements, laboratory tests and carotid ultrasound examination, and the possible confounding factors were adjusted. Multivariate logistic regression model was used to explore the relationship between LAP and carotid atherosclerosis. Results Compared to male and those aged over 60 years old, females and those aged 60 years old or below had a higher LAP index, and the differences were statistically significant (all P < 0.001). Regression analysis showed that for every standard deviation increase in the lipid accumulation product, the risk of carotid artery plaque increased by 6% (OR=1.06, 95% CI: 1.01-1.12, P=0.026). Interaction analysis results showed that compared with female and non-drinking people, male and drinking people with high risk of cardiovascular diseases have a higher risk of carotid plaque (interaction tests P < 0.05, respectively). Conclusions In people with high risk of cardiovascular diseases, the LAP was positively correlated with the carotid plaque, and the positive correlation were stronger in male and alcohol drinking. -
