Catheter ablation is the most effective rhythm-control option in patients with atrial fibrillation (AF) and is currently considered and option mainly for improving symptoms. We aimed to assess the impact of catheter ablation on hard clinical outcomes. We performed a systematic review of randomized controlled trials comparing catheter ablation vs. optimized medical treatment. We searched MEDLINE, EMBASE and CENTRAL on January 8th, 2024, for trials published ≤10 years. We pooled data risk ratio (RR) & mean differences (MD), with 95% confidence interval (CI), and calculated the Number Needed to Treat (NNT). Sub-group and sensitivity analyses were performed for presence/absence of heart failure (HF), paroxysmal/persistent AF, early ablation, higher/lower quality, and published ≤5 vs >5 years. Twenty-two randomized controlled trials were identified, including 6,400 patients followed for 6 to 52 months. All primary endpoints were significantly reduced by catheter ablation vs. medical management: all-cause hospitalization (RR=0.57, 95%CI 0.39-0.85, P=0.006), AF relapse (RR=0.48, 95%CI 0.39-0.58, P<0.00001), all-cause mortality (RR=0.69, 95%CI 0.56-0.86, P=0.0007, NNT=44.7) driven trials with HF patients. A benefit was also demonstrated for all secondary endpoints: cardiovascular mortality (RR=0.55, 95%CI 0.34-0.87), cardiovascular (RR=0.83, 95%CI 0.71-0.96) and HF hospitalizations (RR=0.71, 95%CI 0.56-0.89), AF burden (MD=20.6%, 95%CI 5.6-35.5), LVEF recovery (MD=5.7%, 95%CI 3.5-7.9) and quality of life (MLHFQ, AFEQT & SF-36 scales). Catheter ablation significantly reduced hospitalizations, AF burden and relapse, and improved quality of life. An impact on hard clinical outcomes, with an important mortality reduction and improvement in LVEF, was seen for patients with AF and HF.
导管消融术是心房颤动(房颤)患者最有效的节律控制方法,目前主要用于改善症状。我们的目的是评估导管消融术对硬性临床结果的影响。 我们对比较导管消融与优化医疗的随机对照试验进行了系统回顾。我们检索了 2024 年 1 月 8 日在 MEDLINE、EMBASE 和 CENTRAL 上发表时间不超过 10 年的试验。我们汇总了风险比(RR)和平均差异(MD)的数据,以及 95% 的置信区间(CI),并计算了需要治疗的人数(NNT)。我们对是否存在心力衰竭(HF)、阵发性/持续性房颤、早期消融、质量较高/较低以及发表时间≤5年与>5年进行了分组和敏感性分析。 共确定了22项随机对照试验,包括6400名随访6至52个月的患者。导管消融与药物治疗相比,所有主要终点均显著降低:全因住院率(RR=0.57,95%CI 0.39-0.85,P=0.006)、房颤复发率(RR=0.48,95%CI 0.39-0.58,P<0.00001)、全因死亡率(RR=0.69,95%CI 0.56-0.86,P=0.0007,NNT=44.7)均明显降低。以下所有次要终点也显示出了获益:心血管死亡率(RR=0.55,95%CI 0.34-0.87)、心血管(RR=0.83,95%CI 0.71-0.96)和 HF 住院率(RR=0.71,95%CI 0.56-0.89)、房颤负担(MD=20.6%,95%CI 5.6-35.5)、LVEF 恢复(MD=5.7%,95%CI 3.5-7.9)和生活质量(MLHFQ、AFEQT 和 SF-36 量表)。 导管消融大大降低了住院率、房颤负担和复发率,并改善了生活质量。房颤合并心房颤动的患者的临床疗效明显改善,死亡率明显降低,LVEF明显改善。

In acute decompensated heart failure (HF), systemic venous congestion contributes to patients’ symptoms and hospital admissions. The purpose of our study is to determine if venous congestion, examined using the Venous Excess Ultrasound (VExUS) score, predicts heart failure-related hospitalisation and mortality in patients admitted to the Emergency Department (ED) with acute decompensated heart failure. 50 patients admitted for acute HF in ED underwent ultrasound assessment according to the VExUS score within the first 24 hours and 72 hours. All patients were followed-up with a telephone call at 30 and 60 days after the hospital discharge. On admission, 56% had a VEXUS score 3. After 72 hours, 32% had no more signs of congestion at the Doppler VEXUS examination (VCI < 2 cm, VEXUS score 0), a similar percentage still exhibited a VEXUS score 3 despite therapy. 80% of patients were hospitalised after the admission to the ED, whilst six (15%) died in-hospital, all exhibited a first assessment VExUS 3 score. No patient with a VExUS score below 3 died during the study. During short-term follow-up, 18 patients were re-admitted to ED for acute decompensated HF. 94% of the re-admitted patients had a VExUS score 3 at the Doppler assessment at the first ED admission. Severe venous congestion, defined as a VExUS score of 3 at the initial assessment of patients with acute decompensated HF predicts in-patient mortality, HF-related death, and early readmission.
在急性失代偿性心力衰竭(HF)中,全身静脉充血是导致患者出现症状和住院的原因之一。我们的研究旨在确定使用静脉过度超声(VExUS)评分检查静脉充血是否能预测急诊科(ED)收治的急性失代偿性心力衰竭患者与心力衰竭相关的住院治疗和死亡率。 急诊科收治的 50 名急性心力衰竭患者在最初 24 小时和 72 小时内接受了根据 VExUS 评分进行的超声评估。出院后 30 天和 60 天,对所有患者进行了电话随访。 入院时,56% 的患者的 VEXUS 评分为 3 分。72 小时后,32% 的患者在多普勒 VEXUS 检查中不再有充血迹象(VCI < 2 厘米,VEXUS 得分为 0),尽管接受了治疗,但仍有类似比例的患者 VEXUS 得分为 3。80%的患者在进入急诊室后被送往医院,有6名患者(15%)在院内死亡,所有患者的首次评估VExUS评分均为3分。研究期间,VExUS 评分低于 3 分的患者无一死亡。在短期随访期间,有 18 名患者因急性失代偿性心房颤动再次入住急诊室。94%的再次入院患者在首次入院时的多普勒评估中 VExUS 得分为 3 分。 严重静脉充血的定义是急性失代偿性心房颤动患者初次评估时 VExUS 得分为 3 分,这预示着住院死亡率、与心房颤动相关的死亡和早期再入院。

Over several decades the approach to treating dyslipidemias during pregnancy remains essentially unchanged. The lack of advancement in this field is mostly related to the fact that we lack clinical trials of pregnant patients both with available as well as new therapies. While there are numerous novel therapies developed for nonpregnant patients, there are still many limitations in dyslipidemia treatment during pregnancy. Besides pharmacotherapy and careful clinical assessment, the initiation of behavioral modifications as well as pre-conception management are very important. Among the various lipid-lowering medications, bile acid sequestrants are the only ones officially approved for treating dyslipidemia in pregnancy. Ezetimibe and fenofibrate can be considered if their benefits outweigh potential risks. Statins are still considered contraindicated, primarily due to animal studies and human case reports. However, recent systematic reviews and meta-analyses as well as data on familial hypercholesterolemia (FH) in pregnant patients have indicated that their use may not be harmful and could even be beneficial in certain selected cases. This is especially relevant for pregnant patients at very high cardiovascular risk, such as those who have already experienced an acute cardiovascular event or have homozygous or severe forms of heterozygous FH. In these cases, the decision to continue therapy during pregnancy should weigh the potential risks of discontinuation. Bempedoic acid, olezarsen, evinacumab, evolocumab and alirocumab, and inclisiran, are options to consider just before and after pregnancy is completed. In conclusion, decisions regarding lipid-lowering therapy for pregnant patients should be personalized. Despite the challenges in designing and conducting studies in pregnant women, there is a strong need to establish the safety and efficacy of dyslipidemia treatment during pregnancy.
几十年来,治疗孕期血脂异常的方法基本上没有什么变化。这一领域缺乏进展的主要原因是,我们缺乏对妊娠期患者使用现有疗法和新疗法的临床试验。虽然针对非孕期患者开发了许多新型疗法,但孕期血脂异常治疗仍存在许多局限性。除了药物治疗和仔细的临床评估外,行为调整和孕前管理也非常重要。在各种降脂药物中,胆汁酸螯合剂是唯一被正式批准用于治疗妊娠期血脂异常的药物。如果依折麦布和非诺贝特的益处大于潜在风险,可以考虑使用。他汀类药物仍被认为是禁忌药物,主要原因是动物实验和人类病例报告。然而,最近的系统综述和荟萃分析以及有关妊娠患者家族性高胆固醇血症(FH)的数据表明,使用他汀类药物可能无害,在某些特定情况下甚至可能有益。这一点对于心血管风险极高的孕妇尤为重要,例如已经发生过急性心血管事件或患有同型或严重的杂合子高胆固醇血症的孕妇。在这些情况下,决定在妊娠期间继续治疗时应权衡停止治疗的潜在风险。本贝多酸、奥利沙砷、依维那库单抗、依维洛库单抗和阿利洛库单抗以及clisiran都是在妊娠前后可以考虑的选择。总之,有关妊娠患者降脂治疗的决定应该是个性化的。尽管在设计和开展孕妇研究方面存在挑战,但亟需确定孕期血脂异常治疗的安全性和有效性。

We aimed to investigate the influence of socioeconomic position (SEP) and multimorbidity on cross-sectional health care utilization and prognosis in patients after cardiac resynchronization therapy (CRT) implantation. We included first-time CRT recipients with left ventricular ejection fraction ≤35% implanted between 2000-2017. Data on chronic conditions, use of health care services and demographics were obtained from Danish national administrative and health registries. Health care utilization (in- and outpatient hospitalizations, activities in general practice) was compared by multimorbidity categories and SEP by using negative binomial regression model. The association between of SEP, multimorbidity and prognostic outcomes were analyzed using Cox proportional hazards regression. We followed 2.007 patients (median age of 70), 79% were males, 75% were on early retirement or state pension, 37% were living alone, and 41% had low education level) for 5.2 (IQR; 2.2-7.3) years. In adjusted regression models, higher number of chronic conditions were associated with increased health care utilization. Both cardiovascular and non-cardiovascular hospital contacts were increased. Patients with low SEP had higher number of chronic conditions, but SEP had limited influence on health care utilization. Patients living alone and those with low educational level had a trend towards higher risk of all-cause mortality (adjusted hazard ratio: 1.17, 95% confidence interval [CI] 1.03-1.33 and 1.09, 95% CI 0.96-1.24). Multimorbidity increased the use of cross-sectional health care services, whereas low SEP had minor influence on the utilizations. Living alone and low educational level showed a trend toward higher risk of mortality after CRT implantation.
我们旨在研究社会经济地位(SEP)和多病症对心脏再同步化治疗(CRT)植入术后患者横断面医疗利用率和预后的影响。 我们纳入了 2000-2017 年间首次植入 CRT 且左室射血分数≤35% 的患者。有关慢性病、医疗服务使用情况和人口统计学的数据来自丹麦国家行政和健康登记处。通过负二项回归模型,比较了多病类别和SEP的医疗保健利用率(住院和门诊、全科诊疗活动)。使用 Cox 比例危险度回归分析了 SEP、多病症和预后结果之间的关系。我们对 2 007 名患者(中位年龄为 70 岁,79% 为男性,75% 领取提前退休或国家养老金,37% 独居,41% 受教育程度低)进行了为期 5.2(IQR;2.2-7.3)年的随访。在调整后的回归模型中,慢性病数量越多,医疗保健使用率越高。心血管疾病和非心血管疾病患者的住院次数都有所增加。低 SEP 患者的慢性病数量较多,但 SEP 对医疗使用率的影响有限。独居患者和受教育程度低的患者全因死亡风险呈上升趋势(调整后危险比:1.17,95% 置信区间 [CI] 1.03-1.33 和 1.09,95% CI 0.96-1.24)。 多病症增加了跨部门医疗服务的使用率,而低 SEP 对使用率的影响较小。独居和教育水平低的患者在植入 CRT 后死亡风险呈上升趋势。

The pathophysiology of orthostatic hypotension (OH), a common clinical condition, associated with adverse outcomes, is incompletely understood. We examined the relationship between OH and circulating endostatin, an endogenous angiogenesis inhibitor with antitumor effects proposed to be involved in blood pressure (BP) regulation. We compared endostatin levels in 146 patients with OH and 150 controls. A commercial chemiluminescence sandwich immunoassay was used to measure circulating levels of endostatin. Linear and multivariate logistic regressions were conducted to test the association between endostatin and OH. Endostatin levels were significantly higher in OH patients (59,024 ± 2513 pg/mL) versus controls (44,090 ± 1978 pg/mL, p<0.001). A positive linear correlation existed between endostatin and the magnitude of systolic BP decline upon standing (p<0.001). Using multivariate analysis, endostatin was associated with OH (adjusted odds ratio per 10% increase of endostatin in the whole study population = 1.264, 95%CI 1.141-1.402), regardless of age, sex, prevalent cancer, and cardiovascular disease, as well as traditional cardiovascular risk factors.

正静息性低血压(OH)是一种常见的临床症状,与不良预后相关,但其病理生理学尚不完全清楚。我们研究了OH与循环内司他丁之间的关系,内司他丁是一种内源性血管生成抑制剂,具有抗肿瘤作用,被认为参与血压(BP)调节。 我们比较了 146 例 OH 患者和 150 例对照组的内司他丁水平。我们使用一种商用化学发光夹心免疫测定法来测量内司他丁的循环水平。我们进行了线性和多变量逻辑回归,以检验内司他丁与OH之间的关系。 OH患者的内生长抑素水平(59,024 ± 2513 pg/mL)明显高于对照组(44,090 ± 1978 pg/mL,P<0.001)。内抑素与站立时收缩压下降的幅度呈正线性相关(p<0.001)。通过多变量分析,内司他丁与OH相关(整个研究人群中内司他丁每增加10%的调整赔率=1.264,95%CI 1.141-1.402),与年龄、性别、流行性癌症和心血管疾病以及传统的心血管风险因素无关。 循环内ostatin在正性低血压患者中升高,可作为正性低血压患者心血管风险增加的潜在临床标志物。我们的研究结果需要外部验证。还需要进一步的研究来阐明潜在的病理生理机制。

The retrospective NEPTUNO study evaluated the effectiveness of the CNIC-polypill (including acetylsalicylic acid, ramipril, and atorvastatin) vs other therapeutic approaches in secondary prevention for cardiovascular (CV) disease. In this substudy, the focus was on the subgroup of patients with ischaemic heart disease (IHD). Patients on four strategies: CNIC-polypill, its monocomponents as loose medications, equipotent medications, and other therapies. The primary endpoint was the incidence of recurrent major adverse CV events (MACE) after two years. After matching, 1,080 patients were included in each cohort. The CNIC-polypill cohort had a significantly lower incidence of recurrent MACE compared to Monocomponents, Equipotent drugs, and Other therapies cohorts (16.1% vs 24%, 24.4%, and 24.3%, respectively; P<0.001). The hazard ratios (HR) for recurrent MACE were higher in Monocomponents (HR=1.12; P=0.042), Equipotent drugs (HR=1.14; P=0.031), and Other therapies cohorts (HR=1.17; P=0.016) compared to the CNIC-polypill, with a number needed to treat of 12 patients to prevent a MACE. The CNIC-polypill demonstrated a greater reduction in low-density lipoprotein cholesterol (-56.1% vs -43.6%, -33.3%, and -33.2% in the Monocomponents, Equipotent drugs, and Other therapies, respectively; P<0.001) and systolic blood pressure (-13.7% vs -11.5%, -10.6%, and -9.1% in the CNIC-polypill, Monocomponents, Equipotent drugs, and Other therapies, respectively; P<0.001) compared to other cohorts. The CNIC-polypill intervention was less costly and more effective than any other therapeutic option, with €2,317–€2,407 cost savings per event prevented. In IHD, the CNIC-Polypill exemplifies a guideline-recommended secondary prevention treatment linked to better outcomes and cost-saving compared to other therapeutic options.
回顾性 NEPTUNO 研究评估了 CNIC 多联疗法(包括乙酰水杨酸、雷米普利和阿托伐他汀)与其他治疗方法在心血管疾病二级预防中的有效性。在这项子研究中,重点是缺血性心脏病(IHD)患者亚组。 接受四种策略治疗的患者:CNIC-多聚酶抑制剂、其单成分散剂、等效药物和其他疗法。主要终点是两年后复发主要心血管不良事件(MACE)的发生率。经过匹配后,每个队列共纳入了 1080 名患者。与单克隆抗体、等效药物和其他疗法队列相比,CNIC-多聚酶抑制剂队列的复发性MACE发生率明显较低(分别为16.1% vs 24%、24.4%和24.3%;P<0.001)。与 CNIC 聚能丸相比,单组分(HR=1.12;P=0.042)、等效药物(HR=1.14;P=0.031)和其他疗法(HR=1.17;P=0.016)组别中复发性 MACE 的危险比(HR)更高,需要治疗 12 例患者才能预防 MACE。CNIC-多聚酶抑制剂对低密度脂蛋白胆固醇的降低幅度更大(单组分、等效药物和其他疗法分别为-56.1% vs -43.6%、-33.3%和-33.2%;P<0.001)和收缩压(CNIC-多丸、单一成分、等效药物和其他疗法分别为-13.7% vs -11.5%、-10.6%和-9.1%;P<0.001)。与其他治疗方案相比,CNIC-多聚酶抑制剂干预的成本更低,效果更好,每预防一起事件可节省成本2317-2407欧元。 与其他治疗方案相比,CNIC-多聚酶抑制剂是心肌缺血二级预防治疗指南推荐的典范,可带来更好的疗效并节约成本。

The prevalence of atrial fibrillation (AF) is positively correlated with prior cardiovascular diseases (CVD) and CVD risk factors, but is lower in Chinese than Europeans despite their higher burden of CVD. We examined the prevalence and prognosis of AF and other ECG abnormalities in the China Kadoorie Biobank. A random sample of 25,239 adults (mean age 59.5 years, 62% women) had a 12-lead ECG recorded and interpreted using a Mortara VERITAS™ algorithm in 2013-2014. Participants were followed-up for 5 years for incident stroke, ischaemic heart disease (IHD), heart failure (HF) and all CVD, overall and by CHA2DS2-VASc scores, age, sex, and area. Overall, 1.2% had AF, 13.6% had left ventricular hypertrophy (LVH), and 28.1% had ischaemia (two-thirds of AF cases also had ischaemia or LVH). The prevalence of AF increased with age, prior CVD and levels of CHA₂DS₂-VASc scores (0.5%, 1.3%, 2.1%, 2.9%, and 4.4% for scores <2, 2, 3, 4,  ≥ 5, respectively). AF was associated with 2-fold higher hazard ratios (HR) for CVD (2.15; 95% CI, 1.71–2.69) and stroke (1.88; 1.44–2.47), and a 4-fold higher HR for HF (3.79; 2.21–6.49). The 5-year cumulative incidence of CVD was comparable for AF, prior CVD and CHA₂DS₂-VASc scores ≥2 (36.7% vs 36.2% vs 37.7%, respectively), but was 2-fold greater than for ischaemia (19.4%), LVH (18.0%) or normal ECG (14.1%), respectively. The findings highlight the importance of screening for AF together with estimation of CHA₂DS₂-VASc scores for prevention of CVD in Chinese adults.
心房颤动(AF)的发病率与既往心血管疾病(CVD)和心血管疾病风险因素呈正相关,但尽管中国人的心血管疾病负担较重,但其发病率却低于欧洲人。我们研究了中国嘉道理生物库中房颤和其他心电图异常的患病率和预后。 2013-2014年,我们随机抽取了25239名成年人(平均年龄59.5岁,62%为女性)进行12导联心电图记录,并使用Mortara VERITAS™算法进行解读。对参与者进行了为期 5 年的随访,以了解中风、缺血性心脏病 (IHD)、心力衰竭 (HF) 和所有心血管疾病的总体情况以及 CHA2DS2-VASc 评分、年龄、性别和地区。 总体而言,1.2%的人患有心房颤动,13.6%的人患有左心室肥厚(LVH),28.1%的人患有缺血(三分之二的心房颤动病例同时患有缺血或左心室肥厚)。房颤患病率随年龄、既往心血管疾病和 CHA₂DS₂-VASc 评分的增加而增加(评分<2、2、3、4、≥5 分别为 0.5%、1.3%、2.1%、2.9% 和 4.4%)。心房颤动导致心血管疾病(2.15;95% CI,1.71-2.69)和中风(1.88;1.44-2.47)的危险比(HR)增加 2 倍,导致心房颤动的危险比增加 4 倍(3.79;2.21-6.49)。房颤、既往心血管疾病和 CHA₂DS₂-VASc 评分≥2(分别为 36.7% vs 36.2% vs 37.7%)的心血管疾病 5 年累积发病率相当,但分别比缺血(19.4%)、左心室肥大(18.0%)或心电图正常(14.1%)的发病率高 2 倍。 研究结果凸显了筛查心房颤动并估算CHA₂DS₂-VASc评分对中国成年人预防心血管疾病的重要性。

Reduced muscle mass and strength is frequently associated with both alterations in blood lipids and poorer cardiometabolic outcomes in epidemiological studies; however, a causal association cannot be determined from such observations. Two-sample Mendelian randomization (MR) was applied to assess the association of genetically determined appendicular lean mass (ALM) and handgrip strength (HGS) with serum lipid particle diameter. MR was implemented using summary-level data from the largest genome-wide association studies (GWAS) on ALM (n = 450,243), HGS (n = 223,315) and lipoprotein (LDL, VLDL and HDL) particle diameters (n = 115,078). Inverse variance weighted method (IVW) was used to calc ulate the causal estimates. Weighted median (WM)-based method, and MR-Egger, leave-one-out method were applied as sensitivity analysis. Greater ALM had a statistically significant positive effect on HDL particle diameter (MR-Egger: β=0.055, SE = 0.031, p = 0.081; IVW: β=0.068, SE = 0.014, p < 0.001), and a statistically significant negative effect on VLDL particle diameter (MR-Egger: β= −0.114, SE = 0.039, p = 0.003; IVW: β= −0.081, SE = 0.017, p < 0.001). Similarly, greater HGS had a statistically significant positive effect on HDL particle diameter (MR-Egger: β=0.433, SE = 0.184, p = 0.019; IVW: β=0.121, SE = 0.052, p = 0.021), and a statistically significant negative effect on VLDL particle diameter (MR-Egger: β=−0.416, SE = 0.163, p = 0.011; IVW: β=−0.122, SE = 0.046, p = 0.009). There was no statistically significant effect of either ALM or HGS on LDL particle diameter. There were potentially causal associations between both increasing ALM and HGS, and increasing HDL particle size and decreasing VLDL particle size. These causal associations may offer possibilities for interventions aimed at improving CVD risk profile.
在流行病学研究中,肌肉质量和力量的降低往往与血脂的改变和较差的心脏代谢结果有关;但是,无法从这些观察结果中确定因果关系。本研究采用双样本孟德尔随机化(MR)方法来评估由基因决定的附肢瘦体重(ALM)和握力(HGS)与血清脂质颗粒直径之间的关联。 MR是利用最大的全基因组关联研究(GWAS)中关于ALM(n = 450,243)、HGS(n = 223,315)和脂蛋白(LDL、VLDL和HDL)颗粒直径(n = 115,078)的汇总级数据实现的。采用逆方差加权法 (IVW) 计算因果关系估计值。作为敏感性分析,采用了基于加权中位数(WM)的方法和 MR-Egger、leave-one-out 方法。 ALM越大,对高密度脂蛋白(HDL)颗粒直径的影响越大(MR-Egger:β=0.055,SE=0.031,p=0.081;IVW:β=0.068,SE=0.014,p<0.001),对低密度脂蛋白(VLDL)颗粒直径的影响越小(MR-Egger:β=-0.114,SE=0.039,p=0.003;IVW:β=-0.081,SE=0.017,p<0.001)。同样,更大的 HGS 对高密度脂蛋白颗粒直径也有统计学意义上的积极影响(MR-Egger:β=0.433,SE=0.184,p=0.019;IVW:β=0.121,SE=0.052,p=0.021),对 VLDL 颗粒直径有统计学意义的显著负效应(MR-Egger:β=-0.416,SE=0.163,p=0.011;IVW:β=-0.122,SE=0.046,p=0.009)。ALM或HGS对低密度脂蛋白颗粒直径的影响均无统计学意义。 ALM 和 HGS 的增加与高密度脂蛋白粒径的增加和低密度脂蛋白粒径的减小之间可能存在因果关系。这些因果关系可能为旨在改善心血管疾病风险状况的干预措施提供了可能性。

Similarly, greater HGS had a statistically significant positive effect on HDL particle diameter (MR-Egger: β=0.433, SE = 0.184, p = 0.019; IVW: β=0.121, SE = 0.052, p = 0.021), and a statistically significant negative effect on VLDL particle diameter (MR-Egger: β=−0.416, SE = 0.163, p = 0.011; IVW: β=−0.122, SE = 0.046, p = 0.009). There was no statistically significant effect of either ALM or HGS on LDL particle diameter.\u0000 \u0000 \u0000 \u0000 There were potentially causal associations between both increasing ALM and HGS, and increasing HDL particle size and decreasing VLDL particle size. These causal associations may offer possibilities for interventions aimed at improving CVD risk profile.\u0000","PeriodicalId":505595,"journal":{"name":"European Heart Journal Open","volume":"10 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140244248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
