Lipid levels and risk of new-onset atrial fibrillation: A systematic review and dose-response meta-analysis

Lipid levels are closely associated with health, but whether lipid levels are associated with atrial fibrillation (AF) remains controversial. We thought that blood lipid levels may influence new-onset AF. Here, we used a meta-analysis to examine the overall association between lipid levels and new-onset AF. PubMed and EMBASE databases were searched up to 20 December 2019. We conducted a systematic review and quantitative meta-analysis of prospective studies to clarify the association between lipid levels and the risk of new-onset AF. Sixteen articles with data on 4 032 638 participants and 42 825 cases of AF were included in this meta-analysis. The summary relative risk (RR) for a 1 mmol/L increment in total cholesterol (TC) was 0.95 (95% CI 0.93-0.96, I² = 74.6%, n = 13). Subgroup analyses showed that follow-up time is a source of heterogeneity; for low-density lipoprotein cholesterol (LDL-C), RR was 0.95 (95% CI 0.92-0.97, I² = 71.5%, n = 10). Subgroup analyses indicated that adjusting for heart failure explains the source of heterogeneity; for high-density lipoprotein cholesterol (HDL-C), RR was 0.97 (95% CI 0.96-0.99, I² = 26.1%, n = 11); for triglycerides (TGs), RR was 1.00 (95% CI 0.96-1.03, I² = 81.1%, n = 8). Subgroup analysis showed that gender, age, follow-up time, and adjustment for heart failure are sources of heterogeneity. Higher levels of TC, LDL-C, and HDL-C were associated with lower risk of new-onset AF. TG levels were not associated with new-onset AF in all subjects.

非高密度脂蛋白胆固醇可以替代低密度脂蛋白胆固醇吗?

非高密度脂蛋白胆固醇(non-HDL-C)等于总胆固醇减去高密度脂蛋白胆固醇。流行病学研究认为,在糖尿病、甘油三酯过高和低密度脂蛋白胆固醇(LDL-C)过低的人群中,non-HDL-C比LDL-C更能反映动脉粥样硬化性心血管疾病的发病风险,预测能力更强。对于动脉粥样硬化性心血管疾病患者,non-HDL-C的目标值已被写进欧美血脂指南和中国胆固醇教育计划专家建议,但关于non-HDL-C能否完全替代LDL-C目前尚无定论。现简述近年来non-HDL-C相关研究进展,并将non-HDL-C与LDL-C进行比较,从而明确non-HDL-C的临床价值。     

冠心病患者及其高危人群血脂检测对比分析

目的 根据美国国家胆固醇教育计划成人治疗组第三次指南(NCEP-ATPⅢ)提出的冠心病和高危人群的血浆低密度脂蛋白胆固醇(LDL-C)水平应控制在≤2.6mmol/L的标准,观察本地区冠心病和高危人群的LDL-C异常情况。方法 分析220例冠状动脉造影(CAG)确诊的冠心病患者(CHD组)及90例富含冠心病危险因素CAG阴性者(NCHD)的胆固醇(TC)、甘油三酯(TG)、LDL-C、高密度脂蛋白胆固醇(HDL-C)水平及异常率。结果 与非冠心病组相比,冠心病组的平均TC和LDL-C水平明显增高、HDL-C水平降低(P<0.05)。按NCEP-ATPⅢ,LDL-C≥2.6mmol/L和HDL-C≤1mmol。L为异常,冠心病组LDL-C和HDL-C异常率明显大于非冠心病组,分剐为67％vs 47％和50％vs 27％(P<0.001)。冠心病组患者LDL-C水平的迭标率为33％左右。结论LDL-C水平升高和HDL-C水平降低是本地区冠心病发生和发展的关键。冠心病及其高危人群在他汀类药物的应用应加强并且有很大空间。通过药物开发提高HDL-C水平在防治冠心病事件方面将有很好的前景。     

Alteration of platelet counts and lipid profiles after treatment of acute Plasmodium vivax

During malaria infections, thrombocytopenia and low cholesterol levels are frequently observed changes. We compared these changes in patients admitted with fevers and infected with Plasmodium vivax, patients admitted with fevers with respiratory/urinary infections and afebrile normal (control) non-infected volunteers. Changes in the platelet count and lipid parameters are reported for malaria patients after treatment with hydroxychloroquine and primaquine for acute P. vivax malaria. Of a total 141 participants, 55 patients were diagnosed with malaria (positive blood smear) prior to treatment. Compared to the normal (n=52) and non-malaria fever groups (n=34), there was a significant decrease in five hematologic indices (white blood cell, red blood cell, hemoglobin, hematocrit and platelet) and three lipid parameters (total cholesterol, HDL-c and LDL-c) in the vivax malaria group at day 0 (pre-treatment). Following treatment, the platelet counts returned to normal limits (P<0.05) from 91,058/microL on day 0 to 246,833/microL by day 17 after treatment. However, changes in the lipid parameters of malaria patients showed a slow recovery to normal limits compared to the platelet counts. The HDL-c and LDL-c remained low for 1 month after treatment but increased at 3 and 6 months post-treatment. At 12 months after treatment, the levels of two lipid parameters had fully recovered to the normal limits. Thus, special attention should be applied when interpreting laboratory blood profiles of malaria patients, especially platelet and lipid based tests, until full recovery after treatment.     

Are dietary amino acids prospectively predicts changes in serum lipid profile?

BackgroundBesides of dietary fat and carbohydrate, amino acids(AAs), as constituent components of dietary protein have been related with serum lipid levels. This study aims to examine the association between dietary AAs and prospective changes in serum lipid profile in adults.MethodsAnalyses were conducted on 3881 participants aged, 18–75 years of Tehran lipid and Glucose study, at baseline (2008–2011) and were followed for 3 years (2011–2014) to ascertain serum lipid profile changes. Dietary intakes of AAs were collected at baseline using food frequency questionnaire. Multiple linear regression adjusted for age, sex, body mass index, physical activity, smoking and daily intakes of energy, total fat, and fiber were used.ResultsThe median(IQR) changes in triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) were 6.0(-19.0, −35.5), 9.0(7.0, −24.0), 1.0(-3.0, −6.0), and 5.2(-8.0, −18.6) mg/dl, respectively. Higher intakes of isoleucine, lysine, tyrosine, alanine, threonine, methionine, valine, histidine, aspartic acid, and branched chain, alkaline, and alcoholic AAs were positively associated with TGs-changes in the final adjusted model, whereas tryptophan, glutamic acid, and acidic AAs were negatively related to TG-changes. Alanine and tryptophan were associated with higher and lower LDL-C-changes, respectively. Lysine, alanine, methionine, aspartic acid, and alkaline AAs showed positive association with changes in TC, whereas tryptophan and glutamic acid had a negative association with TC-changes.ConclusionOur findings showed that some dietary amino acids have the potential to increase or decrease serum lipid profile.
