摘 要:目的 了解2002年至2007年中老年人群颈动脉斑块的变化情况,评价基线血脂水平对新发颈动脉斑块的预测作用.方法 研究样本来自中美队列中的石景山人群和多省市队列中的北京大学社区人群.2002年9月对这两个人群进行基线颈动脉超声检查和心血管病危险因素调查,2007年9至10月复查颈动脉超声.以两次颈动脉检查数据完整的2000名中老年人为研究对象,对基线血脂水平与颈动脉斑块的关系进行分析.结果 (1)2002年至2007年,颈动脉斑块患病率男性从30.3%增加到62.2%,女性从21.5%增加到51.5%;新发斑块率男性为41.8%,女性为34.1%.(2)男女两性颈动脉新发斑块率随着基线总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、非高密度脂蛋白胆固醇(non-HDL-C)及总胆固醇与HDL-C比值(TC/HDL-C)水平的增高而增加,其变化趋势差异均有统计学意义(P<0.05或P<0.01).(3)交叉分析显示,LDL-C,HDL-C,甘油三酯对斑块发生率有协同作用.(4)多因素分析显示,高LDL-C、高non-HDL-C和高TC/HDL-C是男女两性新发颈动脉斑块的独立影响因素(男性OR值分别为1.44、1.45、1.59,女性OR值分别为1.47、1.35、1.64,均P<0.05).结论 2002年至2007年,中老年人群颈动脉斑块患病率在快速增长.高LDL-C、nonHDL-C和TC/HDL-C水平是中老年人群新发颈动脉斑块的独立预测指标.Objective To evaluate the prediction value of blood lipid levels on the newly-identified carotid plaque in middle-aged and elderly Chinese population. Methods All study subjects were recruited from two cohorts from 2002 to 2007 [the People's Republic of China/United States of America collaborative study ( USA-PRC study) and the Chinese multi-provincial cohort study (CMCS)]. The baseline examination including cardiovascular disease risk factors and B-mode ultrasound of carotid artery was performed in 2002and the second examination was made in September to October, 2007. The relationship between baseline lipids and carotid plaque incidence was analyzed in a total of 2000 subjects aged 47 to 79 years ( mean 63years). Results (1) During these 5 years, the prevalence of carotid plaque increased from 30. 3% to 62. 2% and from 21.5% to 51.5% for men and women, respectively. The newly-identified carotid plaque incidence was 41.8% for men and 34. 1 % for women. (2) The incidence of artery plaque significantly increased in both sexes in proportion to increase of baseline total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and total to high-density cholesterol ratio (TC/HDL-C) levels ( P 〈 0.05 or P 〈 0. 01 ). (3) Cross-stratification analysis of LDL-C,triglyceride (TG) and HDL-C for carotid plaque incidence indicated the existence of conjoint effects between LDL-C and HDL-C, LDL and TG, as well as between TG and HDL-C, on the increased incidence of carotid plaque. (4) Multi-factorial analysis showed that higher LDL-C, non-HDL-C and TC/HDL-C were independent risk factors for development of new carotid plaque [OR = 1.44 (95% CI = 1.07 - 1. 94), OR =1.45(95% CI=1.08-1.96),OR=1.59(95% CI=1. 14-2.23) in men;OR=1.47(95% CI= 1. 13-1.92 ), OR = 1.35 (95% CI= 1.04 - 1.75), OR= 1. 64 (95% CI = 1.20 - 2. 23 ) in women]. Conclusions The prevalence of carotid plaque increased rapidly i
