摘要
目的:探讨在不同的LDL-C水平,血脂相关剩余风险与大动脉粥样硬化性脑卒中(large artery atherosclerotic,LAA)的相关性。方法:前瞻性、多中心的中国国家卒中登记研究(China National Stroke Registry,CNSR)数据库中入选的3 492例LAA脑卒中患者,与3 022例非大动脉粥样硬化非小血管闭塞性(non large artery atherosclerosis&small vessel occlusion,Non LAA&SAO)脑卒中患者作为研究人群,多因素logistic回归分析在不同LDL-C水平,血脂相关剩余风险与LAA脑卒中的关系。结果:在LDL-C≥2.59mml/L,低HDL-C与LAA脑卒中风险增加相关(OR=1.20,P=0.027)。高TG、高nonHDL-C、高TG并低HDL-C均与LAA脑卒中发生不相关。在LDL-C<2.59mmol/L,HDL-C每增加1mmol/L,LAA脑卒中发生的相对风险下降45%(OR=0.55,P<0.0001)。HDL-C最低三分位(<1.04)组与最高三分位(≥1.33)组比较,低HDL-C与LAA脑卒中风险比率增加相关(OR=1.64,P=0.03)。non-HDL-C每增加1mmol/L,LAA脑卒中发生的风险比率增加79%(OR=1.79,P<0.0001)。non-HDLC最高三分位(≥2.96)组与最低三分位(<2.46)组比较,高non-HDL-C与LAA脑卒中风险增加正相关(OR=1.5,P<0.001)。TG水平最低三分位组(<0.97)与最高三分位组(≥1.59)比较,高TG水平与LAA脑卒中风险增加正相关(OR=1.38,P<0.001)。TG/HDL-C比值每增加1个单位,LAA脑卒中相对风险增加12%[OR=1.12,P=0.002]。TG/HDL-C比值最高三分位与最低三分位比较,TG/HDL-C比值升高与LAA脑卒中风险增加独立相关(OR=1.30,P<0.0001)。结论:HDL-C水平降低是LAA脑卒中风险增加的独立危险因素,独立于LDL-C水平。在LDL-C达到<2.59mmol/L,高TG、高non-HDLC、高TG并低HDL-C是LAA脑卒中的血脂相关剩余风险。
