Elevated nonfasting triglycerides indicate the presence of remnant lipoproteins, which may promote atherosclerosis.
To test the hypothesis that very high levels of nonfasting triglycerides predict myocardial infarction (MI), ischemic heart disease (IHD), and death.
DESIGN, SETTING, AND PARTICIPANTS: A prospective cohort study of 7587 women and 6394 men from the general population of Copenhagen, Denmark, aged 20 to 93 years, followed up from baseline (1976-1978) until 2004.
Hazard ratios (HRs) for incident MI, IHD, and total death according to baseline nonfasting triglyceride level categories of 1 to 1.99 mmol/L (88.5-176.1 mg/dL), 2 to 2.99 mmol/L (177.0-264.6 mg/dL), 3 to 3.99 mmol/L (265.5-353.0 mg/dL), 4 to 4.99 mmol/L (354.0-441.6 mg/dL), and 5 mmol/L or more (> or =442.5 mg/dL) vs triglyceride levels of less than 1 mmol/L (<88.5 mg/dL).
With increasing levels of nonfasting triglycerides, levels of remnant lipoprotein cholesterol increased. During a mean follow-up of 26 years, 1793 participants (691 women and 1102 men) developed MI, 3479 (1567 women and 1912 men) developed IHD, and 7818 (3731 women and 4087 men) died. For MI, among women, the age-adjusted HRs and multifactorially adjusted HRs (aHRs) for each respective category per 1-mmol/L increase in nonfasting triglyceride levels were 2.2 (aHR, 1.7), 4.4 (aHR, 2.5), 3.9 (aHR, 2.1), 5.1 (aHR, 2.4), and 16.8 (aHR, 5.4); for both, P for trend < .001. For MI, among men, the values were 1.6 (aHR, 1.4), 2.3 (aHR, 1.6), 3.6 (aHR, 2.3), 3.3 (aHR, 1.9), and 4.6 (aHR, 2.4); for both, P for trend < .001. For IHD, among women, the values were 1.7 (aHR, 1.4), 2.8 (aHR, 1.8), 3.0 (aHR, 1.8), 2.1 (aHR, 1.2), and 5.9 (aHR, 2.6); for both, P for trend < .001. For IHD, among men, the values were 1.3 (aHR, 1.1), 1.7 (aHR, 1.3), 2.1 (aHR, 1.3), 2.0 (aHR, 1.2), and 2.9 (aHR, 1.5); P for trend < .001 for age-adjusted and P for trend = .03 for multifactorially adjusted. For total death, among women, the values were 1.3 (aHR, 1.3), 1.7 (aHR, 1.6), 2.2 (aHR, 2.2), 2.2 (aHR, 1.9), and 4.3 (aHR, 3.3); for both, P for trend < .001. For total death, among men, the values were 1.3 (aHR, 1.2), 1.4 (aHR, 1.4), 1.7 (aHR, 1.5), 1.8 (aHR, 1.6), and 2.0 (aHR, 1.8); for both, P for trend < .001.
In this general population cohort, elevated nonfasting triglyceride levels were associated with increased risk of MI, IHD, and death in men and women.
非空腹甘油三酯升高表明存在残留脂蛋白,这可能会促进动脉粥样硬化。
检验非空腹甘油三酯水平极高可预测心肌梗死(MI)、缺血性心脏病(IHD)和死亡这一假设。
设计、地点和参与者:一项对丹麦哥本哈根普通人群中7587名女性和6394名男性进行的前瞻性队列研究,年龄在20至93岁之间,从基线(1976 - 1978年)随访至2004年。
根据基线非空腹甘油三酯水平分类,即1至1.99毫摩尔/升(88.5 - 176.1毫克/分升)、2至2.99毫摩尔/升(177.0 - 264.6毫克/分升)、3至3.99毫摩尔/升(265.5 - 353.0毫克/分升)、4至4.99毫摩尔/升(354.0 - 441.6毫克/分升)和5毫摩尔/升及以上(≥442.5毫克/分升),与甘油三酯水平低于1毫摩尔/升(<88.5毫克/分升)相比,发生MI、IHD和全因死亡的风险比(HR)。
随着非空腹甘油三酯水平升高,残留脂蛋白胆固醇水平也升高。在平均26年的随访期间,1793名参与者(691名女性和1102名男性)发生MI,3479名(1567名女性和1912名男性)发生IHD,7818名(3731名女性和4087名男性)死亡。对于MI,在女性中,非空腹甘油三酯水平每升高1毫摩尔/升,各相应分类的年龄调整后HR和多因素调整后HR(aHR)分别为2.2(aHR,1.7)、4.4(aHR,2.5)、3.9(aHR,2.1)、5.1(aHR,2.4)和16.8(aHR,5.4);两者趋势P均<0.001。对于MI,在男性中,数值分别为1.6(aHR,1.4)、2.3(aHR,1.6)、3.6(aHR,2.3)、3.3(aHR,1.9)和4.6(aHR,2.4);两者趋势P均<0.001。对于IHD,在女性中,数值分别为1.7(aHR,1.4)、2.8(aHR,1.8)、3.0(aHR,1.8)、2.1(aHR,1.2)和5.9(aHR,2.6);两者趋势P均<0.001。对于IHD,在男性中,数值分别为1.3(aHR, 1.1)、1.7(aHR, 1.3)、2.1(aHR, 1.3)、2.0(aHR, 1.2)和2.9(aHR, 1.5);年龄调整后趋势P<0.001,多因素调整后趋势P = 0.03。对于全因死亡,在女性中,数值分别为1.3(aHR,1.3)、1.7(aHR,1.6)、2.2(aHR,2.2)、2.2(aHR,1.9)和4.3(aHR,3.3);两者趋势P均<0.001。对于全因死亡,在男性中,数值分别为1.3(aHR,1.2)、1.4(aHR,1.4)、1.7(aHR,1.5)、1.8(aHR,1.6)和2.0(aHR,1.8);两者趋势P均<0.001。
在这个普通人群队列中,非空腹甘油三酯水平升高与男性和女性发生MI、IHD及死亡的风险增加相关。
