    癫痫与急性心肌梗死(AMI)风险之间的关系尚未完全了解。斯德哥尔摩心脏研究的证据表明,癫痫患者患AMI的风险增加。本研究旨在分析患病率的时间趋势,不良临床结局,癫痫患者AMI的危险因素。
    18岁或以上的患者,2008年1月1日至2017年12月31日被诊断为患有或不患有AMI的癫痫,并从国家住院样本(NIS)数据库中确定。使用SAS9.4进行Cochran-Armitage趋势检验和逻辑回归。针对多个变量生成赔率(OR)。
    共有8,456,098名住院患者符合我们的分析条件,包括与AMI共病的181,826例(2.15%)。PWE中AMI诊断的患病率从2008年的每100,000例住院1,911.7显着增加到2017年的每100,000例住院2,529.5(P趋势<0.001)。与没有AMI的患者相比,患有AMI的癫痫患者的住院死亡率明显更高(OR=4.61,95%CI:4.54至4.69)。PWE中与AMI显著相关的因素包括年龄(≥75岁与18~44岁,OR=3.54,95%CI:3.45至3.62),动脉粥样硬化(OR=4.44,95%CI:4.40至4.49),传导障碍(OR=2.21,95%CI:2.17至2.26),心肌病(OR=2.11,95%CI:2.08至2.15),凝血功能障碍(OR=1.52,95%CI:1.49至1.54),血脂异常(OR=1.26,95%CI:1.24至1.27),消化性溃疡(OR=1.23,95%CI:1.13至1.33),慢性肾脏病(OR=1.23,95%CI:1.22至1.25),吸烟(OR=1.20,95%CI:1.18至1.21),和体重减轻(OR=1.20,95%CI:1.18至1.22)。
    十年来,PWE中AMI的患病率有所增加。这些人群的死亡率很高,强调医生需要全面关注PWE中危险因素的预防和AMI的早期诊断。
    UNASSIGNED: The relationship between epilepsy and risk of acute myocardial infarction (AMI) is not fully understood. Evidence from the Stockholm Heart Study indicates that the risk of AMI is increased in people with epilepsy. This study aims to analyze the temporal trends in prevalence, adverse clinical outcomes, and risk factors of AMI in patients with epilepsy (PWE).
    UNASSIGNED: Patients aged 18 years or older, diagnosed with epilepsy with or without AMI and hospitalized from January 1, 2008, to December 31, 2017, were identified from the National Inpatient Sample (NIS) database. The Cochran-Armitage trend test and logistic regressions were conducted using SAS 9.4. Odds ratios (ORs) were generated for multiple variables.
    UNASSIGNED: A total of 8,456,098 inpatients were eligible for our analysis, including 181,826 comorbid with AMI (2.15%). The prevalence of AMI diagnosis in PWE significantly increased from 1,911.7 per 100,000 hospitalizations in 2008 to 2,529.5 per 100,000 hospitalizations in 2017 (Ptrend  < 0.001). Inpatient mortality was significantly higher in epilepsy patients with AMI compared to those without AMI (OR = 4.61, 95% CI: 4.54 to 4.69). Factors significantly associated with AMI in PWE included age (≥75 years old vs. 18 ~ 44 years old, OR = 3.54, 95% CI: 3.45 to 3.62), atherosclerosis (OR = 4.44, 95% CI: 4.40 to 4.49), conduction disorders (OR = 2.21, 95% CI: 2.17 to 2.26), cardiomyopathy (OR = 2.11, 95% CI: 2.08 to 2.15), coagulopathy (OR = 1.52, 95% CI: 1.49 to 1.54), dyslipidemia (OR = 1.26, 95% CI: 1.24 to 1.27), peptic ulcer disease (OR = 1.23, 95% CI: 1.13 to 1.33), chronic kidney disease (OR = 1.23, 95% CI: 1.22 to 1.25), smoking (OR = 1.20, 95% CI: 1.18 to 1.21), and weight loss (OR = 1.20, 95% CI: 1.18 to 1.22).
    UNASSIGNED: The prevalence of AMI in PWE increased during the decade. Mortality rates were high among this population, highlighting the need for comprehensive attention to prophylaxis for risk factors and early diagnosis of AMI in PWE by physicians.

    右冠状动脉(AORCA)的先天性异常起源与不协调的过程是一种罕见的畸形,可以表现为劳累性胸痛,晕厥,心律失常,心力衰竭,和心源性猝死.我们介绍了一例42岁的男性,有高胆固醇血症病史,在运动两周后出现胸痛和头晕。体检并不明显,患者血流动力学稳定。最初的血液检查是正常的。心电图(ECG)显示在56bpm时窦性心动过缓,无ST或T波变化。心脏压力测试表明前顶可诱导的缺血,压力诱发的缺血概率中等。计算机断层扫描血管造影(CTA)显示AORCA在肺动脉和主动脉之间具有较高的动脉间通道。随后的左心导管检查证实了异常起源并显示了动脉粥样硬化疾病。由于右冠状动脉(RCA)受压,该异常被确定为患者症状的原因。患者接受阿司匹林和他汀类药物治疗,并成功进行了乳内动脉-RCA旁路移植术。术后,病人的症状得到缓解,并且没有进一步的胸痛发作。
    The congenital anomalous origin of the right coronary artery (AORCA) with an incongruous course is a rare malformation that can manifest as exertional chest pain, syncope, arrhythmias, heart failure, and sudden cardiac death. We present a case of a 42-year-old male with a history of hypercholesterolemia who presented with chest pain and dizziness upon exertion for two weeks. The physical examination was unremarkable, and the patient was hemodynamically stable. Initial blood tests were normal. Electrocardiogram (ECG) showed sinus bradycardia at 56 bpm without ST or T wave changes. A cardiac stress test indicated antero-apical inducible ischemia with a moderate probability of stress-induced ischemia. Computed tomography angiography (CTA) revealed an AORCA with a high interarterial course between the pulmonary artery and the aorta. Subsequent left heart catheterization confirmed the anomalous origin and revealed atherosclerotic disease. This anomaly was identified as the cause of the patient\'s symptoms due to the compression of the right coronary artery (RCA). The patient was treated with aspirin and statin and underwent successful internal mammary artery-RCA bypass grafting. Postoperatively, the patient\'s symptoms resolved, and there were no further episodes of chest pain.

    随着印度尼西亚动脉粥样硬化性心血管疾病(ASCVD)病例的增加,越来越需要确定高危患者的心血管事件复发.风险分层可以指导最佳的二级预防治疗。了解ASCVD的直接住院费用可以进一步为减轻印度尼西亚大量ASCVD病例带来的经济负担提供见解。然而,印度尼西亚对这两个有价值的数据的大规模研究存在显着差距。采用SMART-REACH模型,我们可以描述印度尼西亚ASCVD患者心血管事件复发的风险.
    利用SMART-REACH模型估计印度尼西亚ASCVD患者心血管事件的10年和终生风险,并描述ASCVD的直接住院费用。
    这项描述性横断面研究收集了来自两个主要心血管中心的3,209名45-80岁的ASCVD患者的数据。参与者是2020年1月至2023年3月期间收治的ST段抬高型心肌梗死(STEMI)患者,非ST段抬高型心肌梗死(NSTEMI),和慢性冠状动脉综合征(CCS)需要择期经皮冠状动脉介入治疗(PCI)。SMART-REACH风险估计模型需要入院时的临床数据,入院前24小时内的实验室结果,出院时开的心血管药物。SMART-REACH模型是一种精细和灰色竞争风险模型,结合了心血管风险因素,可估计包括心肌梗死在内的复发性心血管事件的个体10年和终生风险。中风,或血管死亡。直接住院费用分析总计从ASCVD诊断入院到出院所产生的所有医疗费用。结果采用亚组分析进行描述性报道。
    队列(平均年龄60.15±8.6岁)主要是男性[n=2,537(79.1%)],高血压[n=2,267(70.6%)],并诊断为STEMI[n=1,732(54%)]。SMART-REACH模型计算的平均10年风险为30.2%(95%CI29.7-30.6),终生风险为62.5%(95%CI62.1-62.9)。ASCVD患者的直接住院费用包括中位数3,033美元,在STEMI亚组中,成本中位数最高(3,270美元)。
    大量印度尼西亚ASCVD患者表现出经历重大心血管事件的10年和终生风险。加上直接住院费用,治疗优化对于减轻这些风险和进一步的成本负担至关重要.
    UNASSIGNED: With atherosclerotic cardiovascular disease (ASCVD) cases increasing in Indonesia, there is a growing need to identify high-risk patients for recurrent cardiovascular events. Risk stratification could guide optimal secondary preventive therapy. Understanding the ASCVD direct inpatient costs could further provide insight in reducing the economic burden that comes with Indonesia\'s high number ASCVD cases. However, there is a significant gap in Indonesian large-scale research on both of these valuable data. Employing the SMART-REACH model, we can profile the risk of recurrent cardiovascular events in Indonesian ASCVD patients.
    UNASSIGNED: Utilize the SMART-REACH model to estimate 10-year and lifetime risk of cardiovascular events in Indonesian ASCVD patients and describe the direct inpatient cost of ASCVD.
    UNASSIGNED: This descriptive cross-sectional study gathered data from 3,209 ASCVD patients aged 45-80 from two major cardiovascular centers using purposive sampling. Participants were patients admitted between January 2020 and March 2023 with ST-elevated myocardial infarct (STEMI), non-ST-elevated myocardial infarct (NSTEMI), and chronic coronary syndrome (CCS) requiring elective percutaneous coronary intervention (PCI). The SMART-REACH risk estimation model required clinical data upon admission, laboratory results within the first 24 h of admission, and cardiovascular medication prescribed upon discharge. The SMART-REACH model is a Fine and Gray competing risk model incorporating cardiovascular risk factors that estimates individual 10-year and lifetime risk for recurrent cardiovascular events which includes myocardial infarction, stroke, or vascular death. Direct inpatient cost profiling totaled all medical expenses incurred from ASCVD diagnosis admission to discharge. Results were reported descriptively with subgroup analyses.
    UNASSIGNED: The cohorts (mean age 60.15 ± 8.6 years) were predominantly male [n = 2,537 (79.1%)], hypertensive [n = 2,267 (70.6%)], and diagnosed with STEMI [n = 1,732 (54%)]. The SMART-REACH model calculated a mean 10-year risk of 30.2% (95% CI 29.7-30.6) and a lifetime risk of 62.5% (95% CI 62.1-62.9). The direct inpatient cost of ASCVD patients includes a median 3,033 USD, with highest median costs in the STEMI subgroup (3,270 USD).
    UNASSIGNED: A significant number of Indonesian ASCVD patients exhibited notably high 10-year and lifetime risks of experiencing a major cardiovascular event. Combined with the direct inpatient cost, therapy optimization is crucially needed to mitigate these risks and further cost burden.

    经皮冠状动脉介入治疗(PCI)已成为动脉粥样硬化性心血管疾病(ASCVD)的主要治疗手段。炎症因子已被证明参与ASCVD的发生和发展。PCI术后炎症的持续性,尤其是在靶病变处释放的炎症,可能影响非靶病变斑块的稳定性。白细胞介素-6(IL-6)是最常见的炎症因子之一。然而,关于IL-6对冠状动脉非靶病变(NTL)进展的影响的研究有限.这项研究调查了血清IL-6水平是否会影响冠状动脉支架植入术后NTL的进展。
    我们进行了一项回顾性队列研究,包括接受冠状动脉造影(CAG)和支架植入的441例患者,至少有一个NTL,2019年1月至2021年12月。他们在PCI术后9至12个月接受了CAG随访。四分位数分组基于再入院后的血清IL-6水平。采用Logistic回归分析和限制性三次样条回归分析血清IL-6水平与冠状动脉支架植入术后NTLs进展的关系。使用接受者工作特征(ROC)曲线评估IL-6对NTL进展的预测值。
    当与第一个四分位数(Q1)组相比时,NTL进展的概率在第二季度增加(调整后比值比(AOR)3.06,95%CI1.29-7.29),第三季度(AOR3.55,95%CI1.52-8.26),和第四季度组(aOR7.51,95%CI3.30-17.05),趋势检验p<0.001。随着IL-6水平的升高,NTL进展的风险逐渐增加,IL-6与NTLs进展呈非线性关系(p<0.001)。ROC曲线显示血清IL-6水平临界值为12.652pg/mL(曲线下面积为0.673,灵敏度为54.5%,特异性为70.9%,p<0.05)。
    高血清IL-6水平是冠状动脉支架植入术后NTLs进展的独立危险因素,对NTLs的进展有一定的预测价值。
    UNASSIGNED: percutaneous coronary intervention (PCI) has become the mainstay of treatment for atherosclerotic cardiovascular disease (ASCVD). Inflammatory factors have been shown to be involved in the initiation and progression of ASCVD. After PCI, the persistence of inflammation, especially the inflammation released at the target lesion, may affect the stability of non-target lesion plaques. Interleukin-6 (IL-6) is one of the most common inflammatory factors, however studies about the influence of IL-6 on the progression of non-target lesions (NTLs) of coronary artery are limited. This study investigated whether serum IL-6 levels can affect the progression of NTLs after coronary stent implantation.
    UNASSIGNED: We performed a retrospective cohort study including 441 patients undergoing coronary angiography (CAG) and stent implantation, who had at least one NTL, between January 2019 and December 2021. They underwent followup CAG 9 to 12 months after PCI. Quartile grouping was based on serum IL-6 levels following readmission. The relationship between serum IL-6 levels and the progression of NTLs after coronary stent implantation was analyzed by using logistic regression analysis and restricted cubic spline regression. Predictive value of IL-6 on NTL progression was evaluated using the receiver operating characteristic (ROC) curve.
    UNASSIGNED: When compared to the first quartile (Q1) group, the probability of NTL progression was increased in Q2 (adjusted odds ratio (aOR) 3.06, 95% CI 1.29-7.29), Q3 (aOR 3.55, 95% CI 1.52-8.26), and Q4 group (aOR 7.51, 95% CI 3.30-17.05), with a trend test p < 0.001. With the increase of IL-6 levels, the risk of progression of NTLs gradually increased, and there was a non-linear relationship between IL-6 and progression of NTLs (p < 0.001). The ROC curve showed that the critical value of the serum IL-6 level was 12.652 pg/mL (area under the curve is 0.673, sensitivity is 54.5%, specificity is 70.9%, p < 0.05).
    UNASSIGNED: A high serum IL-6 level is an independent risk factor for the progression of NTLs after coronary stent implantation, and has certain predictive value for the progression of NTLs.

    在几个心脏病学临床实践指南中建议共享决策(SDM)和基于多学科团队的护理交付。然而,利益的证据和实施指导是有限的。知情同意,使用患者决策辅助工具,或者政府或社会机构的这些要素的文档可以混为一谈。SDM是专家之间的双向交流:患者是目标的专家,值,和偏好,和临床医生提供他们关于临床因素的专业知识。在这个专家小组的视角中,我们回顾了SDM在基于团队的心血管护理中的现状,并为多学科团队实施SDM提出了最佳实践建议.
    Shared decision-making (SDM) and multidisciplinary team-based care delivery are recommended across several cardiology clinical practice guidelines. However, evidence for benefit and guidance on implementation are limited. Informed consent, the use of patient decision aids, or the documentation of these elements for governmental or societal agencies may be conflated as SDM. SDM is a bidirectional exchange between experts: patients are the experts on their goals, values, and preferences, and clinicians provide their expertise on clinical factors. In this Expert Panel perspective, we review the current state of SDM in team-based cardiovascular care and propose best practice recommendations for multidisciplinary team implementation of SDM.

    最近的证据表明,血浆卵磷脂-胆固醇酰基转移酶(LCAT)和对氧磷酶-1(PON-1)水平的变化与不同人群过早发生动脉粥样硬化性心血管疾病(ASCVD)的风险增加有关。然而,在尼日利亚和撒哈拉以南非洲,这方面的研究很少。
    这项研究评估了血浆LCAT和PON-1水平降低与ASCVD风险增加之间的关联,以及它们作为ASCVD生物标志物的潜力。
    从拉各斯州立大学教学医院随机选择动脉粥样硬化性心血管疾病患者和健康对照进行这项横断面病例对照研究,Ikeja,拉各斯,尼日利亚,2022年3月至2023年3月。采用夹心酶联免疫吸附法测定血浆LCAT和PON-1,而脂质分布是通过分光光度法测量的。
    总共153名ASCVD患者(平均年龄:52.92±10.24岁)和50名健康对照(平均年龄:46.96±11.05岁)纳入分析。在平均体重中观察到了统计学上的显着增加,臀围,腰围,腰臀比,身体质量指数,舒张压和收缩压(均p≤0.001),和脉搏率(p=0.003)与对照值相比。在平均血浆总胆固醇中也观察到统计学上的显着增加,甘油三酯,低密度脂蛋白胆固醇,和非高密度脂蛋白胆固醇(均p≤0.001)。相比之下,平均血浆高密度脂蛋白胆固醇,LCAT,与对照值相比,PON-1(p≤0.001)显着降低。
    本研究提供了支持性证据,表明血浆LCAT和PON-1的变化可能使个体易患过早ASCVD。
    血浆LCAT和PON-1可以作为独立的标志物或补充其他已建立的心血管疾病标志物,以在不清楚时区分ASCVD的风险。
    UNASSIGNED: Recent evidence has linked changes in plasma lecithin-cholesterol acyltransferase (LCAT) and paraoxonase-1 (PON-1) levels with increased risk for development of premature atherosclerotic cardiovascular disease (ASCVD) in different populations. However, studies on this in Nigeria and sub-Saharan Africa are scarce.
    UNASSIGNED: This study assessed the association between reduced plasma LCAT and PON-1 levels and an increased risk of ASCVD, and their potential as biomarkers for ASCVD.
    UNASSIGNED: Atherosclerotic cardiovascular disease patients and healthy controls were randomly selected for this cross-sectional case-control study from the Lagos State University Teaching Hospital, Ikeja, Lagos, Nigeria, between March 2022 and March 2023. Plasma LCAT and PON-1 were determined by sandwich enzyme-linked immunosorbent assay, while the lipid profile was measured by spectrophotometry.
    UNASSIGNED: A total of 153 ASCVD patients (mean age: 52.92 ± 10.24 years) and 50 healthy controls (mean age: 46.96 ± 11.05 years) were included in the analyses. Stastistically significant increases were observed in the mean body weight, hip circumference, waist circumference, waist-to-hip ratio, body mass index, diastolic and systolic blood pressure (all p ≤ 0.001), and pulse rate (p = 0.003) compared to the control values. Statistically significant increases were also observed in the mean plasma total cholesterol, triglycerides, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol (all p ≤ 0.001). In contrast, the mean plasma high-density lipoprotein cholesterol, LCAT, and PON-1 (p ≤ 0.001) were notably reduced compared to the control values.
    UNASSIGNED: The present study provides supportive evidence that changes in plasma LCAT and PON-1 could predispose individuals to risk of premature ASCVD.
    UNASSIGNED: Plasma LCAT and PON-1 may serve as independent markers or complement other established cardiovascular disease markers to discriminate the risk of ASCVD when it is unclear.

    动脉粥样硬化性心血管疾病的发病率在全球范围内呈上升趋势,特别是在低收入和中等收入国家,尽管在减少传统风险因素方面做出了重大努力。已经记录了过早的亚临床动脉粥样硬化与几种病毒感染有关。最近COVID-19大流行的规模凸显了需要了解SARS-CoV-2与动脉粥样硬化之间的关联。这篇综述探讨了各种病理生理机制,包括内皮功能障碍,血小板活化,以及SARS-CoV-2感染引发的炎症和免疫过度激活,特别注意它们在启动和促进动脉粥样硬化病变进展中的作用。此外,它解决了急性期后COVID-19可能导致血管疾病发展的各种致病机制。了解这些综合征的重叠可以实现新的治疗策略。我们进一步探讨了在近期COVID-19患者中,特别是那些具有心脏代谢危险因素的患者中,经常被忽视的动脉粥样硬化性心血管疾病证据的指南是否需要更密切的随访。
    The incidence of atherosclerotic cardiovascular disease is increasing globally, especially in low- and middle-income countries, despite significant efforts to reduce traditional risk factors. Premature subclinical atherosclerosis has been documented in association with several viral infections. The magnitude of the recent COVID-19 pandemic has highlighted the need to understand the association between SARS-CoV-2 and atherosclerosis. This review examines various pathophysiological mechanisms, including endothelial dysfunction, platelet activation, and inflammatory and immune hyperactivation triggered by SARS-CoV-2 infection, with specific attention on their roles in initiating and promoting the progression of atherosclerotic lesions. Additionally, it addresses the various pathogenic mechanisms by which COVID-19 in the post-acute phase may contribute to the development of vascular disease. Understanding the overlap of these syndromes may enable novel therapeutic strategies. We further explore the need for guidelines for closer follow-up for the often-overlooked evidence of atherosclerotic cardiovascular disease among patients with recent COVID-19, particularly those with cardiometabolic risk factors.

    在对多中心的事后分析中,横断面研究,我们纳入了接受动脉粥样硬化性心血管疾病(ASCVD)一级预防的日本2型糖尿病门诊患者,他们提供了空腹血液样本.评估了实现低密度脂蛋白胆固醇(LDL-C)和非高密度脂蛋白胆固醇(非HDL-C)目标的频率和决定因素。
    在223名平均年龄为67岁、平均HbA1c为7.1%的参与者中,61人无外周动脉疾病史,微血管并发症,或吸烟。在223名参与者中,64.1%(95%CI:57.6-70.1%)达到LDL-C目标。在多变量逻辑回归分析中,为女性(赔率比[OR]3.139,P=0.0011),患有糖尿病肾病(OR2.868,P=0.0021),吸烟(OR2.292,P=0.0281),未使用他汀类药物(OR4.857,P<0.0001)与未成就独立相关。对于非HDL-C,65.6%(95%CI:58.1%-70.6%)的患者达到目标。患有糖尿病神经病变(OR2.428,P=0.0054),吸烟(OR2.008,P=0.0478),和不使用他汀类药物(OR2.277,P=0.0112)被确定为与不成就相关的因素。
    揭示了T2DM中ASCVD一级预防的血脂管理目标的低实现率。评估合并症,鼓励戒烟,并考虑优先使用他汀类药物。
    UNASSIGNED: This study aimed to clarify the real-world status of lipid management in outpatients with type 2 diabetes (T2DM) following the 2022 revision of the Japan Atherosclerosis Society Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases. It also aimed to evaluate characteristics associated with the failure to achieve management targets.
    UNASSIGNED: In this post-hoc analysis of a multicenter, cross-sectional study, we included Japanese outpatients with T2DM undergoing primary prevention of atherosclerotic cardiovascular diseases (ASCVD) who provided fasting blood samples. The frequency and determinants of achieving low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) targets were assessed.
    UNASSIGNED: Among 223 participants with a mean age of 67 and mean HbA1c of 7.1%, 61 had no history of peripheral arterial disease, microvascular complications, or smoking. Out of the 223 participants, 64.1% (95% CI: 57.6-70.1%) achieved the LDL-C target. In multivariate logistic regression analysis, being female (odds ratio [OR] 3.139, P = 0.0011), having diabetic nephropathy (OR 2.868, P = 0.0021), smoking (OR 2.292, P = 0.0281), and non-use of statins (OR 4.857, P < 0.0001) were independently associated with non-achievement. For non-HDL-C, 65.6% (95% CI: 58.1%-70.6%) of patients met the target. Having diabetic neuropathy (OR 2.428, P = 0.0054), smoking (OR 2.008, P = 0.0478), and non-use of statins (OR 2.277, P = 0.0112) were identified as factors associated with non-achievement.
    UNASSIGNED: Low achievement rate of revised lipid management targets for ASCVD primary prevention in T2DM was unveiled. Assessing comorbidities, encouraging smoking cessation, and prioritizing statin use are considered.

    背景:血清脂蛋白(a)[Lp(a)]是普通人群中动脉粥样硬化性心血管疾病(ASCVD)的独立危险因素,在中国维持性血液透析(MHD)患者中,其与ASCVD发病率的相关性尚不清楚.我们旨在评估Lp(a)水平与北京MHD患者ASCVD发病率之间的关系。中国。
    方法:本回顾性研究,观察性队列研究纳入2013年1月1日至2020年12月1日在北京同仁医院就诊的MHD患者,随访至2023年12月1日.主要结果是ASCVD发生。Kaplan-Meier生存分析用于评估MHD患者的无ASCVD生存。基于Lp(a)水平进行分层。进行Cox回归分析以评估Lp(a)水平与ASCVD发生之间的关联。
    结果:本研究共纳入265例患者。中位随访期为71个月。78(29.4%)参与者经历了ASCVD事件,118名(47%)患者死亡,58(49.1%)死亡归因于ASCVD。Spearman等级相关分析显示血清Lp(a)水平与LDL-c水平呈正相关,与血红蛋白呈负相关,甘油三酯,血清铁,血清肌酐,和白蛋白水平。多因素Cox回归分析显示Lp(a)水平≥30mg/L,年龄增长,血清白蛋白水平降低,糖尿病病史与ASCVD发病率显著相关。
    结论:本研究表明MHD患者血清Lp(a)水平与ASCVD风险之间存在独立的正相关,提示血清Lp(a)可能作为评估该人群ASCVD风险的临床生物标志物.
    BACKGROUND: Serum lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD) in the general population, its association with ASCVD incidence in Chinese maintenance hemodialysis (MHD) patients remains unclear. We aimed to evaluate the relationship between Lp(a) levels and ASCVD incidence among MHD patients in Beijing, China.
    METHODS: This retrospective, observational cohort study included MHD patients at Beijing Tongren Hospital from January 1, 2013 to December 1, 2020, and followed until December 1,2023. The primary outcome was ASCVD occurrence. Kaplan-Meier survival analysis was used to evaluate ASCVD-free survival in MHD patients, with stratification based on Lp(a) levels. Cox regression analyses were conducted to assess the association between Lp(a) levels and the occurrence of ASCVD.
    RESULTS: A total of 265 patients were enrolled in the study. The median follow-up period were 71 months.78 (29.4%) participants experienced ASCVD events, and 118 (47%) patients died, with 58 (49.1%) deaths attributed to ASCVD. Spearman rank correlation analyses revealed positive correlations between serum Lp(a) levels and LDL-c levels, and negative correlations with hemoglobin, triglyceride, serum iron, serum creatinine, and albumin levels. Multivariate Cox regression analysis showed that Lp(a) levels ≥ 30 mg/L, increased age, decreased serum albumin levels, and a history of diabetes mellitus were significantly associated with ASCVD incidence.
    CONCLUSIONS: This study demonstrated an independent and positive association between serum Lp(a) levels and the risk of ASCVD in MHD patients, suggesting that serum Lp(a) could potentially serve as a clinical biomarker for estimating ASCVD risk in this population.

    脂蛋白(a)[Lp(a)]在脑血管疾病中的作用是一个重要的话题。在这篇叙述性评论中,已利用相关研究从不同角度全面审查了这种关系。Lp(a)与低密度脂蛋白胆固醇具有相同的结构特征。Lp(a)由肝细胞合成,它的血浆水平是由LPA基因遗传决定的,产生载脂蛋白(a)。大量流行病学研究证实血清Lp(a)水平升高与脑血管事件的发生或复发呈正相关,尤其是缺血性中风,在成年人。应该注意的是,相关强度在研究中有所不同,在孟德尔随机化研究中是边缘的。关于儿科患者,筛查目前仅限于有相关病史的患者。Lp(a)似乎在儿童动脉缺血性中风的发病机理中起重要作用,因为通常不存在环境血栓和动脉粥样硬化因子。新型Lp(a)靶向剂的3期试验,比如pelacarsen和olpasiran,预计将证明它们在降低卒中发生率方面的功效。鉴于文献的丰富性,有必要制定新的目标人群Lp(a)筛查和管理指南,以提供更有效的一级和二级预防.
    The role of lipoprotein (a) [Lp(a)] in cerebrovascular disease is a topic of importance. In this narrative review, pertinent studies have been leveraged to comprehensively examine this relationship from diverse perspectives.Lp(a) shares structural traits with low-density lipoprotein cholesterol. Lp(a) is synthesized by hepatocytes, and its plasma levels are genetically determined by the LPA gene, which produces apolipoprotein (a).Numerous epidemiological studies have confirmed the positive correlation between elevated serum Lp(a) levels and the occurrence or recurrence of cerebrovascular events, especially ischemic strokes, in adults. It should be noted that the correlation strength varies among studies and is marginal in Mendelian randomization studies.Regarding pediatric patients, screening is currently limited to those with a relevant medical history. Lp(a) seems to play a significant role in the pathogenesis of arterial ischemic stroke in children because environmental thrombotic and atherogenic factors are generally not present.Phase 3 trials of novel Lp(a) targeting agents, such as pelacarsen and olpasiran, are anticipated to demonstrate their efficacy in reducing the incidence of stroke. Given the richness of the literature, new guidelines regarding Lp(a) screening and management in targeted populations are warranted to provide more effective primary and secondary prevention.
