    背景:糖尿病是一种常见的慢性代谢性疾病。该疾病的进展促进血管炎症和动脉粥样硬化的形成,导致心血管疾病。基于CCTA的冠状动脉血管周围脂肪组织衰减指数是一种新的非侵入性成像生物标志物,可以反映CCTA图像中血管周围脂肪组织衰减的空间变化和冠状动脉周围的炎症。在这项研究中,提出了一种影像组学方法,以高通量方式从CCTA中提取大量图像特征,并结合临床诊断数据,探索基于CCTA的血管周围脂肪成像数据对糖尿病患者冠心病的预测能力。
    方法:采用R语言进行统计分析,筛选出差异显著的变量。预分离模型用于CCTA血管分割,筛选出冠状动脉周围脂肪区域。PyRadiomics用于计算冠状动脉周围脂肪组织的影像组学特征,和SVM,使用DT和RF对临床数据和影像组学数据进行建模和分析。使用PPV、FPR,AAC,ROC。
    结果:结果表明,年龄存在显着差异,血压,糖尿病患者和无冠心病患者之间的一些生化指标。在1037个计算的放射学参数中,18.3%的人在成像组学特征上表现出显著差异。三种建模方法用于分析不同的临床信息组合,内部血管影像组学信息和冠状动脉血管脂肪影像组学信息。结果表明,在不同的机器学习模型下,完整数据的数据集具有最高的ACC值。支持向量机方法表现出最好的特异性,灵敏度,和这个数据集的准确性。
    结论:在这项研究中,将CCTA的临床数据和冠状动脉影像组学数据进行融合,以预测糖尿病患者冠心病的发生。这为糖尿病患者早期发现冠心病提供了信息,并可以及时进行干预和治疗。
    BACKGROUND: Diabetes is a common chronic metabolic disease. The progression of the disease promotes vascular inflammation and the formation of atherosclerosis, leading to cardiovascular disease. The coronary artery perivascular adipose tissue attenuation index based on CCTA is a new noninvasive imaging biomarker that reflects the spatial changes in perivascular adipose tissue attenuation in CCTA images and the inflammation around the coronary arteries. In this study, a radiomics approach is proposed to extract a large number of image features from CCTA in a high-throughput manner and combined with clinical diagnostic data to explore the predictive ability of vascular perivascular adipose imaging data based on CCTA for coronary heart disease in diabetic patients.
    METHODS: R language was used for statistical analysis to screen the variables with significant differences. A presegmentation model was used for CCTA vessel segmentation, and the pericoronary adipose region was screened out. PyRadiomics was used to calculate the radiomics features of pericoronary adipose tissue, and SVM, DT and RF were used to model and analyze the clinical data and radiomics data. Model performance was evaluated using indicators such as PPV, FPR, AAC, and ROC.
    RESULTS: The results indicate that there are significant differences in age, blood pressure, and some biochemical indicators between diabetes patients with and without coronary heart disease. Among 1037 calculated radiomic parameters, 18.3% showed significant differences in imaging omics features. Three modeling methods were used to analyze different combinations of clinical information, internal vascular radiomics information and pericoronary vascular fat radiomics information. The results showed that the dataset of full data had the highest ACC values under different machine learning models. The support vector machine method showed the best specificity, sensitivity, and accuracy for this dataset.
    CONCLUSIONS: In this study, the clinical data and pericoronary radiomics data of CCTA were fused to predict the occurrence of coronary heart disease in diabetic patients. This provides information for the early detection of coronary heart disease in patients with diabetes and allows for timely intervention and treatment.

    坏死在心血管疾病中的意义已经被认识到。然而,在冠心病(CHD)中尚未广泛研究坏死的分子机制。
    在从GEO数据库下载的GSE20681数据集中获得CHD和对照样品之间的差异表达基因(DEGs)。通过生物信息学分析技术捕获并确定与坏死相关的关键DEGs,包括加权基因共表达网络分析(WGCNA)和两种机器学习算法,而单基因基因集富集分析(GSEA)揭示了它们的分子机制。通过接受者操作特征(ROC)分析选择诊断性生物标志物。此外,对免疫因子浸润程度进行了分析。使用定量实时PCR(qRT-PCR)在体外研究了mRNA水平上关键基因表达的鉴定。
    这里总共识别了94个DE-NRG,其中,FAM166B,NEFL,POLDIP3、PRSS37和ZNF594被鉴定为坏死性凋亡相关生物标志物,基于它们的线性回归模型对不同样本类型具有可接受的能力。在监管分析之后,确定的生物标志物在与血液循环相关的功能上明显丰富,钙离子稳态,MAPK/cAMP/Ras信号通路。单样本GSEA显示APC共刺激和CCR更丰富,冠心病患者的aDC和B细胞相对缺乏。生物信息学和qRT-PCR分析的一致发现证实了NEFL的上调和FAM166B的下调,冠心病中的POLDIP3和PRSS37。
    我们目前的研究确定了5个与坏死相关的基因,这些基因可能是冠心病的诊断标志物,并带来了对冠心病坏死的潜在分子机制的新理解。
    UNASSIGNED: The implication of necroptosis in cardiovascular disease was already recognized. However, the molecular mechanism of necroptosis has not been extensively studied in coronary heart disease (CHD).
    UNASSIGNED: The differentially expressed genes (DEGs) between CHD and control samples were acquired in the GSE20681 dataset downloaded from the GEO database. Key necroptosis-related DEGs were captured and ascertained by bioinformatics analysis techniques, including weighted gene co-expression network analysis (WGCNA) and two machine learning algorithms, while single-gene gene set enrichment analysis (GSEA) revealed their molecular mechanisms. The diagnostic biomarkers were selected via receiver operating characteristic (ROC) analysis. Moreover, an analysis of immune elements infiltration degree was carried out. Authentication of pivotal gene expression at the mRNA level was investigated in vitro utilizing quantitative real-time PCR (qRT-PCR).
    UNASSIGNED: A total of 94 DE-NRGs were recognized here, among which, FAM166B, NEFL, POLDIP3, PRSS37, and ZNF594 were authenticated as necroptosis-related biomarkers, and the linear regression model based on them presented an acceptable ability to different sample types. Following regulatory analysis, the ascertained biomarkers were markedly abundant in functions pertinent to blood circulation, calcium ion homeostasis, and the MAPK/cAMP/Ras signaling pathway. Single-sample GSEA exhibited that APC co-stimulation and CCR were more abundant, and aDCs and B cells were relatively scarce in CHD patients. Consistent findings from bioinformatics and qRT-PCR analyses confirmed the upregulation of NEFL and the downregulation of FAM166B, POLDIP3, and PRSS37 in CHD.
    UNASSIGNED: Our current investigation identified 5 necroptosis-related genes that could be diagnostic markers for CHD and brought a novel comprehension of the latent molecular mechanisms of necroptosis in CHD.

    引言通过合理的生物学机制,牙周炎引起全身炎症负担和反应,从而导致损害远远超出口腔。研究表明牙周炎是冠心病(CHD)和中风的重要危险因素。牙周炎组织的数量越大,牙周炎引起菌血症和全身炎症反应的机会越大。有研究报道,牙周炎和其他常见的口腔感染在动脉粥样硬化的发展中起着重要作用。因此,炎症牙周组织的数量对确定动脉粥样硬化的严重程度具有重要意义。因此,本研究探讨牙周发炎表面积(PISA)对冠状动脉粥样硬化严重程度的影响.材料和方法在这项横断面研究中,共纳入了2023年1月1日至2023年9月30日在埃及英国大学(BUE)牙周病学系就诊的160例患者.只有在过去六个月内接受过冠状动脉造影的患者才被纳入研究,不到60岁,分享了他们以前的病史和冠状动脉造影报告,并给予知情书面同意。记录有关经典冠状动脉危险因素和牙周炎状态以及血管造影结果的数据,并进行适当的统计分析。结果结果显示,除年龄(p<0.047)和低密度脂蛋白胆固醇(LDL-C)(p<0.001)外,牙周发炎表面积(p=0.002)是冠状动脉粥样硬化严重程度的重要独立预测因子。结论牙周面积是冠状动脉粥样硬化严重程度的独立预测因子。
    Introduction Through plausible biological mechanisms, periodontitis causes systemic inflammatory burden and response, thus resulting in damage far beyond the oral cavity. Studies have demonstrated periodontitis to be a significant risk factor for coronary heart disease (CHD) and stroke. The larger the quantum of periodontal inflamed tissue, the greater the chances of periodontitis eliciting bacteremia and systemic inflammatory responses. Studies have reported that periodontitis and other common oral infections play an important role in the development of atherosclerosis. Therefore, the quantity of inflamed periodontal tissue assumes significance in determining the severity of atherosclerosis. Hence, this study investigates the impact of periodontal inflamed surface area (PISA) on the severity of coronary atherosclerosis. Materials and methods In this cross-sectional study, a total of 160 patients who presented at the department of periodontics of The British University in Egypt (BUE) from 1 January 2023 to 30 September 2023 were enrolled. Patients were only enrolled if they had undergone coronary angiography within the last six months, were less than 60 years of age, shared their previous medical history and coronary angiographic report, and gave informed written consent. Data on classic coronary risk factors and periodontal inflammatory status and angiographic findings were recorded and subjected to appropriate statistical analysis. Results The results revealed that the periodontal inflamed surface area (p = 0.002) apart from age (p < 0.047) and low-density lipoprotein cholesterol (LDL-C) (p < 0.001) is a significant independent predictor of the severity of coronary atherosclerosis. Conclusions The periodontal inflamed surface area is an independent predictor of the severity of coronary atherosclerosis.

    具有临界心室的心脏是指存在关于左或右心室不发达是否能够以适当的充盈压力和足够的生理储备有效地支持全身或肺循环的不确定性的情况。儿科心脏病专家经常处理与左心室或右心室不同程度的发育不全相关的先天性心脏病(CHD)。迄今为止,没有具体的指导方针,在不同的中心,有时甚至在不同的时间在同一个中心,手术管理可能是非常不同的。因此,单心室或双心室入路的选择一直存在争议.这项审查的目的是更好地定义“小即太小,大即足够大”,以帮助临床医生做出可能影响患者整个生命的决定。
    A heart with a borderline ventricle refers to a situation where there is uncertainty about whether the left or right underdeveloped ventricle can effectively support the systemic or pulmonary circulation with appropriate filling pressures and sufficient physiological reserve. Pediatric cardiologists often deal with congenital heart diseases (CHDs) associated with various degrees of hypoplasia of the left or right ventricles. To date, no specific guidelines exist, and surgical management may be extremely variable in different centers and sometimes even in the same center at different times. Thus, the choice between the single-ventricle or biventricular approach is always controversial. The aim of this review is to better define when \"small is too small and large is large enough\" in order to help clinicians make the decision that could potentially affect the patient\'s entire life.

    UNASSIGNED: To investigate the correlation between retinal vessel density (VD) parameters with serum B-type natriuretic peptide (BNP) in patients with coronary heart disease (CHD) using novel optical coherence tomography angiography (OCTA) denoising images based on artificial intelligence (AI).
    UNASSIGNED: OCTA images of the optic nerve and macular area were obtained using a Canon-HS100 OCT device in 176 patients with CHD. Baseline information and blood test results were recorded.
    UNASSIGNED: Retinal VD parameters of the macular and optic nerves on OCTA were significantly decreased in patients with CHD after denoising. Retinal VD of the superficial capillary plexus (SCP), deep capillary plexus (DCP) and radial peripapillary capillary (RPC) was strongly correlated with serum BNP levels in patients with CHD. Significant differences were noted in retinal thickness and retinal VD (SCP, DCP and RPC) between the increased BNP and normal BNP groups in patients with CHD.
    UNASSIGNED: Deep learning denoising can remove background noise and smooth rough vessel surfaces. SCP,DCP and RPC may be potential clinical markers of cardiac function in patients with CHD. Denoising shows great potential for improving the sensitivity of OCTA images as a biomarker for CHD progression.

    背景:呼吸道合胞病毒(RSV)感染可能导致早产儿呼吸问题(如支气管肺发育不良(BPD)和呼吸窘迫综合征(RDS))或先天性心脏病(CHD)的严重后果。由于调查不同胎龄(WGA)和伴随的特定合并症对RSV感染负担的影响的研究很少,本研究旨在更好地描述意大利背景下这些高危人群的特征.
    方法:本回顾性研究,纵向和记录关联队列研究涉及2017年至2019年出生在拉齐奥地区(意大利)的婴儿,该研究基于从管理数据库中提取的数据.每个婴儿仅包括在以下队列之一中:(1)BPD-RDS(WGA≤35,有或没有CHD)或(2)CHD(没有BPD和/或RDS)或(3)早产(WGA≤35,没有BPD(和/或RDS)或CHD)。每个队列从出生起随访12个月。与出生时的社会人口统计学相关的信息,检索并描述了RSV和未确定的呼吸药物(URA)的住院情况和随访时的药物消耗。
    结果:总共选择了8,196名婴儿,分类为1,084BPD-RDS,3286例冠心病和3826例早产。超过30%的BPD-RDS队列由早期早产儿(WGA≤29)组成,而早产队列主要由中度早产儿(98.2%)组成,而CHD婴儿主要在足月出生(83.9%)。在后续行动中,尽管队列显示RSV住院比例相似,在BPD-RDS队列中,与早产队列中发生的事件相比,住院的严重程度更高(p<0.01),在BPD-RDS队列中,URA住院比例最高(p<0.0001).此外,BPD-RDS婴儿,与其余队列相比,接受帕利珠单抗预防的频率更高(p<0.0001),并且使用肾上腺素吸入剂治疗的频率更高,和全身使用的糖皮质激素。
    结论:对研究临床结果的评估强调,研究队列出生时的人口统计学和临床特征影响他们对RSV和URA感染的易感程度.因此,有必要对这些人群进行持续监测,以确保及时组织能够满足他们未来的需求的医疗保健系统。
    BACKGROUND: Respiratory Syncytial Virus (RSV) infections may lead to severe consequences in infants born preterm with breathing problems (such as bronchopulmonary dysplasia (BPD) and respiratory distress syndrome (RDS)) or congenital heart diseases (CHD). Since studies investigating the influence of different gestational age (WGA) and concomitant specific comorbidities on the burden of RSV infections are scarce, the present study aimed to better characterize these high-risk populations in the Italian context.
    METHODS: This retrospective, longitudinal and record-linkage cohort study involved infants born between 2017 and 2019 in Lazio Region (Italy) and is based on data extracted from administrative databases. Each infant was exclusively included in one of the following cohorts: (1) BPD-RDS (WGA ≤35 with or without CHD) or (2) CHD (without BPD and/or RDS) or (3) Preterm (WGA ≤35 without BPD (and/or RDS) or CHD). Each cohort was followed for 12 months from birth. Information related to sociodemographic at birth, and RSV and Undetermined Respiratory Agents (URA) hospitalizations and drug consumption at follow-up were retrieved and described.
    RESULTS: A total of 8,196 infants were selected and classified as 1,084 BPD-RDS, 3,286 CHD and 3,826 Preterm. More than 30% of the BPD-RDS cohort was composed by early preterm infants (WGA ≤ 29) in contrast to the Preterm cohort predominantly constitute by moderate preterm infants (98.2%), while CHD infants were primarily born at term (83.9%). At follow-up, despite the cohorts showed similar proportions of RSV hospitalizations, in BPD-RDS cohort hospitalizations were more frequently severe compared to those occurred in the Preterm cohort (p<0.01), in the BPD-RDS cohort was also found the highest proportion of URA hospitalizations (p<0.0001). In addition, BPD-RDS infants, compared to those of the remaining cohorts, received more frequently prophylaxis with palivizumab (p<0.0001) and were more frequently treated with adrenergics inhalants, and glucocorticoids for systemic use.
    CONCLUSIONS: The assessment of the study clinical outcomes highlighted that, the demographic and clinical characteristics at birth of the study cohorts influence their level of vulnerability to RSV and URA infections. As such, continuous monitoring of these populations is necessary in order to ensure a timely organization of health care system able to respond to their needs in the future.

    生活方式的改变导致疾病模式从传染病和营养不良转变为退化性疾病,如冠心病(CHD)。印尼工人和普通民众的心血管疾病患病率不断上升,不仅会给医疗费用带来负担,还会降低工作效率,导致更多的工伤和工伤损失。这项研究的目的是确定冠心病的危险因素(年龄,性别,血压,吸烟,糖尿病,身体质量指数,和每周的体育锻炼)和大学工作人员的冠心病风险水平。在医学院的工人中进行了一项横断面研究,Malikussaleh大学,Lhokseumawe,印度尼西亚。采用Jakarta心血管评分法计算冠心病的风险水平,并采用多元logistic回归模型分析预测模型。我们的数据发现58.2%,25.5%和16.3%的大学工人有低,患有冠心病的中高风险。最终的模型表明,心脏病的风险是由性别决定的,年龄,以及高血压和糖尿病的存在。与女性相比,男性的比值比(OR)30.84,年龄>41岁的OR为11.52,高血压的OR为4.87,糖尿病的OR为13.99,41岁以下的人,没有高血压和糖尿病,分别。总之,我们的数据表明,超过15%的受访者(大学雇员)有冠心病的高风险,并且是男性和老年人,高血压和糖尿病与冠心病的风险相关。因此,在大学中实施预防措施很重要。
    Change in lifestyle leads to change in disease patterns from infectious diseases and malnutrition to degenerative diseases, such as coronary heart disease (CHD). The increasing prevalence of cardiovascular diseases among Indonesian workers and the general public will not only burden medical care expenses but also reduce work productivity, leading to more work-related injuries and work-related losses. The aim of this study was to determine the risk factors for CHD (age, sex, blood pressure, smoking, diabetes mellitus, body mass index, and weekly physical activity) and the CHD risk level among university workers. A cross-sectional study was conducted at workers at School of Medicine, Universitas Malikussaleh, Lhokseumawe, Indonesia. The risk level of CHD was calculated using Jakarta Cardiovascular Score and predicting model analyzed with multiple logistic regression model. Our data found that 58.2%, 25.5% and 16.3% of the university workers had low-, medium- and high-risk to have CHD. The final model indicted that the risk of heart disease was determined by gender, age, and the presence of hypertension and diabetes mellitus. Being male had odds ratio (OR) 30.84, aged >41 years old had OR 11.52, having hypertension had OR 4.87 and having diabetes mellitus had OR 13.99 for having high risk of CHD compared to female, those younger than 41 years old, having no hypertension and having no diabetes mellitus, respectively. In conclusion, our data suggests that more than 15% the respondents (university employees) have high risk of CHD and being male and older, and having hypertension and diabetes mellitus are associated with risk of CHD. Implantation of the preventive measures is therefore important to be implemented at the universities.

    糖尿病(DM)是一种以血糖水平升高为特征的慢性代谢紊乱,严重程度在全球范围内继续上升。本系统评价旨在检查糖尿病的患病率及其相关的合并症。旨在更广泛地了解糖尿病的多方面影响。DM与年龄增长呈正相关,它受到遗传倾向的强烈影响。近年来,1型糖尿病(T1D)的患病率在全球范围内明显增加,广泛的流行病学研究证明了这一点。患有DM的人经常有积极的家族史,并且在父母双方或仅在母亲中存在DM显着放大了遗传易感性。此外,非遗传因素,比如急性心理压力源,肥胖,怀孕,吸烟在DM的发生发展中起着举足轻重的作用。值得注意的是,尿路感染(UTI)是2型糖尿病(T2D)患者和所有T1D患者的常见合并症。T2D很普遍,尤其是女性,其发病率随着年龄的增长而上升。尿路感染在糖尿病患者中普遍存在,尤其是女性,大肠杆菌(E.大肠杆菌)分离物是导致UTI炎症的主要病原体。胰岛素抵抗是糖尿病前期和高血压前期的共同特征。作为这些条件的前兆。在结核病(TB)患病率较高的地区,T2D发病率的增加强调了将DM理解为实质性TB风险因素的重要性。在TB治疗期间,DM与TB风险的三倍升高和不利结果的两倍增加相关。值得注意的是,DM的全球流行导致与合并感染HIV的TB患者相比,合并DM的TB患者人数更多.糖尿病和败血症对全球发病率和死亡率有显著影响。糖尿病个体经历更多的脓毒症后并发症和死亡率增加。高血压和T2D并存是一种常见的共病,糖尿病患者的高血压发病率是糖尿病患者的两倍,通常与胰岛素抵抗和糖尿病发病风险增加有关。
    Diabetes mellitus (DM) is a chronic metabolic disorder characterized by elevated blood glucose levels, severity continues to rise worldwide. This systematic review seeks to examine the prevalence of diabetes and its associated comorbid conditions, aiming to provide insights into the multifaceted impact of diabetes on a broader scale. DM exhibits a positive correlation with advancing age, and it\'s strongly influenced by genetic predisposition. In recent years, there has been a discernible global increase in the prevalence of type 1 diabetes (T1D), as evidenced by extensive epidemiological studies. Individuals with DM frequently have a positive familial history, and the presence of DM in both parents or solely the mother significantly amplifies genetic susceptibility. Moreover, non-genetic factors, such as acute psychological stressors, obesity, pregnancy, and smoking play a pivotal role in the development of DM. Notably, urinary tract infections (UTIs) are a common comorbidity in patients with type 2 diabetes (T2D) and all patients with T1D. T2D is prevalent, particularly among females, and its incidence rises with age. UTIs are prevalent among individuals with diabetes, particularly females, with Escherichia coli (E. coli) isolates being the primary etiological agents responsible for UTI inflammation. Insulin resistance is a common feature in both prediabetes and prehypertension, serving as a precursor to these conditions. The increasing incidence of T2D in regions with high tuberculosis (TB) prevalence emphasizes the significance of understanding DM as a substantial TB risk factor. DM is associated with a threefold elevation in TB risk and a twofold increase in unfavorable outcomes during TB treatment. Notably, the global prevalence of DM has led to a larger population of TB patients with comorbid DM than TB patients coinfected with HIV. Diabetes and sepsis contribute significantly to worldwide morbidity and mortality, with diabetic individuals experiencing more post-sepsis complications and increased mortality. The coexistence of hypertension and T2D is a common comorbidity, with hypertension incidence being twice as high among individuals with diabetes compared to those without, often linked to insulin resistance and a heightened risk of diabetes onset.

    目标:评估竞争风险是否有助于解释为什么最初血清胆固醇高的地区冠心病(CHD)死亡率较高,中风和其他主要心脏病死亡率较低,而最初血清胆固醇较低的人则相反。
    方法:对6个国家的10个最初年龄为40-59岁的男性(N=9063)进行了60年的随访。主要心血管疾病(CVD)组是CHD,中风,和其他不确定病因的心脏病(HDUE),或中风和HDUE(STHD)的组合,以及所有其他死亡原因。精细灰色竞争风险分析应用于CHD与所有其他死亡原因或STHD(直接模式)以及所有其他死亡原因或STHD与CHD(反向模式),并评估了19个协变量(其中3个参考)对结果的原因特异性危害的影响,从而调查潜在的病因作用。还进行了与通过在具有相同终点结果的直接和反向模式下运行Cox模型获得的结果的系统比较,并以图形方式进行了说明。
    结果:与所有其他死亡原因和STHD相比,冠心病死亡率与不同的危险因素关系有关。血清胆固醇的作用至关重要,因为,在这两个比较中,Fine-Gray,其系数对CHD为正且显著,对所有其他死亡原因和STHD为负且显著。根据所考虑的结果类型,CVD域(CHD与STHD)的特定结果类型的风险因素能力不同。在Fine-Gray模型中,风险因子系数较小,而在Cox模型中,风险因子系数较大。Fine-Gray检测不同的风险因素,其系数可能具有相反的代数符号。
    结论:这是第一份报告,通过Fine-Gray竞争风险分析研究了与终身CVD结局相关的大量风险因素,并与直接和反向模式下的Cox模型获得的结果进行了系统的比较。心血管疾病死亡的亚型应在充分认识到某些危险因素因病理而异的情况下进行总结。他们至少应该解开CHD和STHD。
    OBJECTIVE: To assess whether competing risks help explain why regions with initially high serum cholesterol have higher mortality from coronary heart disease (CHD) and lower mortality from stroke and other major heart diseases, while the reverse is found for those with initially lower serum cholesterol.
    METHODS: Ten cohorts of men (N = 9063) initially aged 40-59 in six countries were examined and followed for fatal outcomes for 60 years. Major cardiovascular disease (CVD) groups were CHD, stroke, and other Heart Diseases of Uncertain Etiology (HDUE), or the combination of stroke and HDUE (STHD), along with all other causes of death. Fine-Gray competing risk analysis was applied with CHD versus all other causes of death or STHD (direct mode) and all other causes of death or STHD versus CHD (inverse mode), and the effects of 19 covariates (of which 3 references) on the cause-specific hazard of the outcomes were assessed, thus investigating potential etiologic roles. A systematic comparison with results obtained by running the Cox model in direct and inverse modes with the same end-point results was also performed and illustrated graphically.
    RESULTS: CHD mortality is bound to different risk factor relationships when compared with all other causes of death and with STHD. The role of serum cholesterol is crucial since, in both comparisons, by Fine-Gray, its coefficients are positive and significant for CHD and negative and significant for all other causes of death and STHD. Risk factor capabilities in specific outcome types of the CVD domain (CHD versus STHD) are different depending on the outcome types considered. Risk factor coefficients are smaller in Fine-Gray modelling and larger in the Cox model. Fine-Gray detects different risk factors whose coefficients may have opposite algebraic signs.
    CONCLUSIONS: This is the first report whereby a large group of risk factors are investigated in connection with life-long CVD outcomes by Fine-Gray competing risk analysis, and a systematic comparison is performed with results obtained by Cox models in both direct and inverse modes. Subtypes of CVD mortality should be summed with full awareness that some risk factors vary by pathology, and they should at least be disentangled into CHD and STHD.
