近期研究表明，非空腹测血脂可能影响低密度脂蛋白胆固醇（10w—density lipoprotein—cholesterol，LDL-C）的评估。LDDC新的评估方法（the novelmethod of LDL—Cestimation，LDL—CN）使用一个较灵活的方法来导出患者特异的三酰甘油...近期研究表明，非空腹测血脂可能影响低密度脂蛋白胆固醇（10w—density lipoprotein—cholesterol，LDL-C）的评估。LDDC新的评估方法（the novelmethod of LDL—Cestimation，LDL—CN）使用一个较灵活的方法来导出患者特异的三酰甘油与极低密度脂蛋白胆固醇（verylow—density lipoprotein—cholesterol，VLDL）的比值。展开更多

文摘已知身高越高,体质量越大,心房颤动发生风险越高。然而,心房颤动的风险是否与腹型肥胖有关尚不清楚。Baek等纳入韩国国民健康保险计划全国样本队列中基线无心房颤动的成人501 690人,年龄（47.6±14.3）岁,女性250 664人,占50%。测定其体质量指数（body mass index,BMI）和腰围,将BMI〈18．5kg／m2定义为低体质量，18．5～〈25．0kg／m2定义为正常体质量；25．0～〈30．0kg／m2定义为超重；≥30．0kg／m2定义为肥胖；将腰围≥90（男性）和≥80cm（女性）定义为腹型肥胖。
