Expression and significance of procalcitonin, leukotriene B4, serum amyloid A, and C-reactive protein in children with different types of pneumonia: An observational study. Medicine (Baltimore) 2024; 103:e37817. [PMID: 38728486 PMCID: PMC11081565 DOI: 10.1097/md.0000000000037817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Accepted: 03/15/2024] [Indexed: 05/12/2024] Open
Abstract
This study aimed to investigate the expression and significance of serum procalcitonin (PCT), leukotriene B4 (LTB4), Serum amyloid A (SAA), and C-reactive protein (CRP) in children with different types of pneumonia caused by different pathogenic infections. One hundred and one children with pneumonia admitted to The Fifth People Hospital of Zhuhai from July 2019 to June 2020 were enrolled and divided into 38 cases in the bacterial group, 30 cases in the mycoplasma group, and 33 cases in the virus group according to the different types of pathogens. The patients were divided into 42 cases in the noncritical group, 33 cases in the critical group, and 26 cases in the very critical group according to the pediatric clinical illness score (PCIS), and 30 healthy children were selected as the control group during the same period. Comparison of serum PCT, SAA: bacterial group > mycoplasma group > viral group > control group with significant differences (P < .05). Receiver operator characteristic (ROC) analysis showed that the area under the curves (AUCs) of serum PCT, LTB4, SAA, and CRP for the diagnosis of bacterial pneumonia were 1.000, 0.531, 0.969, and 0.833, respectively, and the AUCs for the diagnosis of mycoplasma pneumonia were 0.653, 0.609, 0.547, and 0.652, respectively, and the AUCs for the diagnosis of viral pneumonia were 0.888, 0.570, 0.955, and 1.000, respectively. Comparison of serum PCT, LTB4, SAA: very critical group > critical group > noncritical group > control group, with significant differences (P < .05). Serum PCT, LTB4, and SAA were negatively correlated with PCIS score by Pearson analysis (P < .05). Serum PCT and SAA showed diagnostic value for bacterial pneumonia, and serum SAA and CRP showed diagnostic value for viral pneumonia; serum PCT, LTB4, and SAA correlate with severity of disease and show higher expression with worsening of the condition.

Attention training technique delivered in groups as treatment for anxiety and depression in patients with coronary heart disease: study protocol for a waiting-list randomized controlled trial. Front Psychol 2023; 14:1226539. [PMID: 37790218 PMCID: PMC10544325 DOI: 10.3389/fpsyg.2023.1226539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Accepted: 08/30/2023] [Indexed: 10/05/2023] Open
Abstract
Introduction Clinically significant symptoms of depression and anxiety in coronary heart disease (CHD) patients are common and associated with adverse outcomes. Psychological treatments have shown limited effectiveness and more effective treatments have been requested. Attention training technique (ATT), a component of metacognitive therapy, can potentially be effective as a stand-alone treatment for anxiety and depression. In an open study, ATT delivered face-to-face in a group format was feasible and potentially effective for improving depression and anxiety symptoms in CHD patients. The next progressive step is to test the effectiveness of ATT in a randomized controlled trial. This paper describes the methodology of this trial. Methods ATT-CHD is a randomized wait-list (WL) controlled study. Eligible CHD patients from two hospitals with Hospital Anxiety and Depression Scale (HADS)-Anxiety and/or HADS-Depression subscales scores ≥8 will be randomized into ATT (n = 32) or WL control (n = 32). After 6-8 weeks, WL patients will be allocated to ATT. Participants will be evaluated pre-, mid- and post-treatment, and at 6-months follow-up using changes in HADS as primary outcome. Secondary outcomes will be changes in psychiatric disorders, rumination, worry, type D-personality, metacognitions, insomnia, quality of life, and C-Reactive protein (CRP). Discussion To our knowledge, this will be the first WL-controlled randomized study testing the effectiveness of group-based ATT as treatment of symptoms of anxiety and depression in CHD patients. It will also explore correlations between changes in psychological distress and CRP. A qualitative analysis will reveal patients' experience with ATT including processes that may facilitate or serve as barriers to effectiveness. Recruitment into the study commenced in December 2022. Ethics and dissemination The Regional Committees for Medical and Health Research Ethics (REK), Norway has granted approval for the study (ID 52002). The trial results will be published in peer-reviewed journals. According to Norwegian legislation, the Norwegian Data Protection Authority, and the Committee of Ethics, we are not allowed to share original study data publicly. Clinical trial registration ClinicalTrials.gov, identifier NCT05621408 pre-inclusion. There were no significant changes of methods or outcomes after study start.

Abstract
The residual risk in patients with atherosclerosis, despite the its controversial aspects, remains an urgent problem of modern cardiology. The article presents a review of publications on the prevalence and significance for determining the prognosis of residual risk, which is currently interpreted as the risk of macroand microvascular complications in patients with atherosclerotic cardiovascular disease (ACVD) taking standard therapy, with the achievement of optimal levels of low-density lipoprotein cholesterol, blood pressure and glucose. Based on available publications, we highlighted current views on the factors associated with residual inflammatory and lipid risks in ACVD patients, including those associated with heart failure and diabetes, and the prognostic significance of residual risk in such patients. An attempt was made to rationale the significance of determining the residual risk for secondary prevention of cardiovascular events.

Abstract
AIM OF THE STUDY In patients undergoing cardiac surgery, preoperative depressive and anxiety symptoms and increased postoperative C-reactive protein (CRP) levels have been associated with adverse outcomes. We tested the hypothesis that preoperative depressive and anxiety symptoms predict elevated in-hospital CRP levels after cardiac surgery. METHODS The study participants were 96 consecutive patients (mean age [SD], 67.6 [10.3] years, 78.1% men) from a single cardiac surgery centre who underwent either isolated coronary artery bypass grafting (CABG) (n = 34), isolated valve surgery (n = 29), combined procedures (including different combinations of CABG, valve surgery, aortic surgery, and others) (n = 30), or other cardiac surgical procedures (n = 3). Participants self-rated depressive and anxiety symptoms using the Patient Health Questionnaire (PHQ-9) and the General Anxiety Disorder (GAD-7) questionnaire before undergoing elective surgery. CRP levels were measured every 24 h up to 10 days post-surgery. Linear mixed (random effects) regression analysis examined the association between preoperative depressive and anxiety symptoms and CRP levels over time, adjusting for pre-surgery CRP levels, demographics, cardiovascular risk factors, medications, and surgery-related variables. RESULTS Before surgery, 32.2% of patients had clinically relevant depressive symptoms (PHQ-9 score ≥5) and 32.2% of patients had clinically relevant anxiety symptoms (GAD-7 score ≥5). More severe depressive symptoms (estimate [95% CI]: 0.081 [0.023, 0.139], p = 0.007) and more severe anxiety symptoms (0.059 [0.005, 0.113], p = 0.032) predicted CRP levels over 10 days, independent of covariates. Furthermore, CRP levels were higher in patients with than in those without clinically relevant depressive symptoms (0.697 [0.204, 1.191], p = 0.006) and were predicted by both more severe somatic (0.132 [0.035, 0.229], p = 0.008) and cognitive (0.128 [0.014, 0.242], p = 0.029) depressive symptoms. CONCLUSIONS Preoperative depressive and anxiety symptoms were independent predictors of elevated CRP levels up to 10 days post-surgery. Such a mechanism may help explain the increased morbidity and mortality risk in patients with depression and anxiety who undergo cardiac surgery.

Neutrophil-to-platelet ratio predicts mortality following percutaneous coronary intervention in patients with acute ST-elevation myocardial infarction. Front Physiol 2022; 13:1011048. [PMID: 36200052 PMCID: PMC9527305 DOI: 10.3389/fphys.2022.1011048] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 08/22/2022] [Indexed: 11/23/2022] Open
Abstract
This study aimed to evaluate the value of neutrophil-to-platelet ratio (NPR) in predicting all-cause mortality in patients with ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PCI). We enrolled 186 patients with STEMI who underwent primary PCI in the Third Affiliated Hospital of Guangzhou Medical University between January 2017 and December 2018. Based on the NPR values, the patients were divided into two groups: the NPR >0.035 group (n = 82) and the NPR ≤0.035 group (n = 104). All-cause mortality of the patients was followed up for 3 years. By the end of 3 years, 109 (58.6%) patients survived, 53 (28.5%) died, and 24 (12.9%) were lost to follow-up. Univariate analyses found that NPR was associated with all-cause mortality (p < 0.05). In COX regression analyses, patients in the high NPR group had a higher risk of all-cause death than those in the low NPR group (HR = 2.296, 95% CI: 1.150–4.582). These results indicate that NPR could predict all-cause death in 3 years after primary PCI in patients STEMI. NPR values may be useful in risk stratification and in specifying individualized treatment in patients with STEMI. In addition, NPR is a low-cost and easily accessible indicator, if its strong predictive value is confirmed in further studies of other large populations, it can be introduced into clinical practice for effective application.

Abstract
Aims High-sensitivity C-reactive protein (hs-CRP), a marker of inflammation, is associated with atherosclerosis, and recent studies indicate that therapies targeting inflammation are associated with reductions in cardiovascular risk. However, factors predictive of elevated hs-CRP in the general population have not been elucidated. Methods In this cross-sectional study, multivariable logistic regression analysis was used to identify independent predictors of elevated hs-CRP (≥3 mg/L) utilizing the National Health and Nutrition Examination Survey (NHANES) 2015-2016 cycle. The model was verified using the independent NHANES 2017-2018 cycle. Candidate variables comprised demographic, behavioral, dietary, and clinical factors. The study included 5412 adults from the 2015-2016 cohort and 5856 adults from the 2017-2018 cohort. Results Significant independent predictors of elevated hs-CRP included: older age (OR 1.09 per decade; 95 % CI 1.03-1.14; P = 0.024), female sex (OR 1.57; 95 % CI 1.36-1.80; P = 0.003), Black vs White race (OR 1.31; 95 % CI 1.10-1.56; P = 0.037), increased BMI (OR 1.12 per kg/m2; 95 % CI 1.10-1.14; P < 0.001), elevated white blood cell count (OR 1.21 per 1000 white blood cells/μL; 95 % CI 1.15-1.28; P = 0.002), and self-reported poor vs excellent health (OR 1.73; 95 % CI 1.04-2.22; P = 0.012). The model had excellent discrimination with a c-statistic of 0.77 in the 2015-2016 cycle and 0.76 in the 2017-2018 cycle. Conclusion Older age, female sex, Black race, increased BMI, higher white blood cell count, and self-reported poor health were independent predictors of elevated hs-CRP levels. Additional studies are needed to determine if behavioral modifications can lower hs-CRP and whether this translates to reduced risk for cardiovascular disease and other conditions associated with chronic inflammation.

Abstract
Metabolomics can discover the biomarkers and metabolic pathways, provides the possibility for insights into the pharmacological action and mechanism of natural products. The therapeutic effect and mechanism of danshensu (DSS) on total metabolic pathways has not been well investigated. The aim of this study was to explore the disturbed endogenous biomarkers and metabolic pathways reflecting the pharmacological activity of DSS, and mechanism of action of DSS using comprehensive metabolome analysis based on high-throughput metabolomics technology combined with ultra-high performance liquid chromatography (UPLC) coupled with quadrupole tandem time-of-flight mass spectrometry (Q-TOF-MS) and pattern recognition method. Through the changes of the overall metabolic profile and the related biomarkers, the intervention effect of natural product danshensu (DSS) treatment on CHD model rats was revealed. The results showed that after the model replication was established, the metabolic profile was clearly separated, and a total of 26 potential biomarkers were screened out, and involving 8 metabolic pathways. After different doses of DSS solution were given, a total of 20 biomarkers could be significantly regulated, mainly involving primary bile acid biosynthesis, glycerophospholipid metabolism, and lipid metabolism. It showed UPLC-MS-based metabolomics can be used for discovering potential biomarkers and metabolic pathways of CHD, and to further understand and dissecting pharmacological effects and mechanisms of natural products via metabolomics techniques.

Correlation between Changes in Serum RBP4, hs-CRP, and IL-27 Levels and Rosuvastatin in the Treatment of Coronary Heart Disease. JOURNAL OF HEALTHCARE ENGINEERING 2021; 2021:8476592. [PMID: 34956579 PMCID: PMC8695037 DOI: 10.1155/2021/8476592] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 11/18/2021] [Accepted: 11/24/2021] [Indexed: 12/03/2022]
Abstract
Objective To investigate the correlation between changes in serum RBP4, hs-CRP, and IL-27 levels and rosuvastatin in the treatment of coronary heart disease (CHD). Methods One hundred and twenty patients with CHD admitted in our hospital were selected as the research object, including 60 patients with acute coronary syndrome as the ACS group, and 60 patients with stable angina as the SA group. Another 60 patients without CHD who were examined in our hospital at the same time were included in the non-CHD group. The patients with CHD were further divided into the control group (CG) (n = 42, with routine treatment) and the study group (SG) (n = 78, with routine treatment and rosuvastatin) to measure serum RBP4, hs-CRP, and IL-27 levels and analyze the correlation between each index and rosuvastatin in the treatment of CHD. Results After retrospective analysis, no significant difference was found among the ACS group, the SA group, and the non-CHD group (P > 0.05). As for serum RBP4, hs-CRP, and IL-27 levels, ACS group > SA group > non-CHD group, with obvious differences among groups (P < 0.05). After Spearman correlation analysis, a positive correlation was observed between Gensini score and serum RBP4, hs-CRP, and IL-27 levels in patients with CHD (P < 0.05). After treatment, serum RBP4, hs-CRP, and IL-27 levels were gradually reduced. At 4 weeks after treatment, serum RBP4, hs-CRP, and IL-27 levels of the CG and the SG were decreased conspicuously, and compared with the control, each index of the SG was obviously lower (P < 0.05). Conclusion Serum RBP4, hs-CRP, and IL-27 play an important role in the occurrence and development of CHD, with a positive correlation to the Gensini score, which can indicate the severity of cardiovascular disease to a certain extent. Meanwhile, rosuvastatin can remarkably reduce serum RBP4, hs-CRP, and IL-27 levels, which is of significance for prognosis.

Abstract
Background To compare clinical and psychological factors among patients with self-perceived statin-associated muscle symptoms (SAMS), confirmed SAMS, and refuted SAMS in coronary heart disease patients (CHD). Methods Data were obtained from a cross-sectional study of 1100 CHD outpatients and a study of 71 CHD outpatients attending a randomized, double-blinded, placebo-controlled, crossover study to test effects of atorvastatin 40 mg/day on muscle symptom intensity. Clinical and psychosocial factors were compared between patients with and without SAMS in the cross-sectional study, and between patients with confirmed SAMS and refuted SAMS in the randomized study. Results Bilateral, symmetric muscle symptoms in the lower extremities during statin treatment were more prevalent in patients with confirmed SAMS compared to patients with refuted SAMS (75% vs. 41%, p = 0.01) in the randomized study. No significant differences in psychological factors (anxiety, depression, worry, insomnia, type D personality characteristics) were detected between patients with and without self-perceived SAMS in the cross-sectional study, or between patients with confirmed SAMS and refuted SAMS, in the randomized study. Conclusions Patients with confirmed SAMS more often present with bilateral lower muscle symptoms compared to those with refuted SAMS. Psychological factors were not associated with self-perceived SAMS or confirmed SAMS. A careful pain history and a search for alternative causes of muscle symptoms are likely to promote communication in patients with SAMS, and may reduce the risk for statin discontinuation.

Abstract
OBJECTIVE To investigate the diagnostic value of scoring model of treadmill exercise test (TET) combined with dynamic electrocardiogram (DECG) for latent coronary heart disease (LCHD). MATERIALS AND METHODS Using coronary angiography, the diagnostic values of TET and DECG alone or combination for LCHD of 200 eligible patients were compared. The effects of different clinical features and DECG indices on the positive detection rate of TET combined with DECG were compared. Multivariate logistic regression analysis was performed for factors influencing diagnostic accuracy, and nomogram prediction model was established using screened independent risk factors. RESULTS Serial and parallel combinations of TET and DECG had superior sensitivity, specificity, positive and negative predictive values and accuracy than those of single detection. Patients with an age > 65 years, smoking, hypertension, diabetes mellitus, hyperlipidemia, family history of CHD and positive DECG indicators had higher positive detection rate, as independent risk factors for accuracy. The diagnostic accuracy of TET combined with DECG predicted by the nomogram model was 82.9%. The actual concordance index (C-index) for model evaluation was 0.817, the C-index after internal validation was 0.811, and the C-index after external validation was 0.802, indicating a good concordance of the model. CONCLUSIONS TET combined with DECG has high diagnostic accuracy for LCHD, and the scoring model constructed by DECG indicators can prominently improve the accuracy of combined diagnosis. Therefore, TET combined with DECG is significantly better than TET or DECG alone, which is of great diagnostic value for LCHD.

Abstract
Sirtuin-1 is a protein that may orchestrate the cardioprotective effect of exercise by controlling cellular processes. This pilot study assessed the feasibility of performing a quasi-experimental study in this area. Patients with postacute myocardial infarction were recruited across four hospital sites in the United Kingdom. The participants were offered one weekly exercise session at Phase-III and Phase-IV cardiac rehabilitation (CR). Measurements were obtained pre-Phase-III CR (Week 1), post-Phase-III CR (Week 8), and post-Phase-IV CR (Week 22). Twenty-eight patients were recruited (79% male, 100% White, 60.2 ± 10.5 years old). The recruitment rate was not fulfilled (<70% eligible patients recruited; 0.9 participants recruited per week over 30 weeks). The success criteria for dropout rate, adherence rate, and collection of sirtuin-1 measures were satisfied. A large increase in sirtuin-1 (0.14 ± 0.03, d ≥ 0.8) was seen after Phase-III and Phase-IV CR. Collectively, a quasi-experimental study is feasible with a revised recruitment strategy.

Abstract
BACKGROUND C-reactive protein (CRP) has been proposed as a contributor to the pathogenesis of coronary artery disease (CAD) and inflammatory reactions, which are associated with a decrease in serum albumin, and it has been reported that the CRP-to-serum albumin ratio (CAR) can predict CAD severity in inpatient ischemic cardiomyopathy (ICM) patients. However, the relationship between the CAR and long-term adverse outcomes in CAD patients after percutaneous coronary intervention (PCI) is still unknown. METHODS A total of 3561 CAD patients enrolled in the Outcomes and Risk Factors of Patients with Coronary Heart Disease after PCI: an investigation based on case records and follow-up (CORFCHD-ZZ), a retrospective cohort study conducted from January 2013 to December 2017, and 1630 patients meeting the study inclusion criteria were divided into two groups based on the CAR (CAR < 0.186; n = 1301 and CAR ≥ 0.186; n = 329). The primary outcome was long-term mortality, including all-cause mortality (ACM) and cardiac mortality. The average follow-up time was 37.59 months. RESULTS We found that there were significant differences between the two groups in the incidences of ACM (P < 0.001) and cardiac mortality (P = 0.003). Cox multivariate regression analyses demonstrated that CAR was an independent predictor of ACM [hazard ratio, 2.678; (95% confidence interval (CI), 1.568-4.576); P < 0.001] and cardiac mortality (hazard ratio, 2.055; 95% CI, 1.056-3.998; P = 0.034) in CAD patients after PCI. CONCLUSION This study revealed that the CAR is an independent and novel predictor of long-term adverse outcomes in CAD patients who have undergone PCI.

Abstract
Despite a significant progress of the recent decades, incidence of cardiovascular complications in patients with manifest, stable ischemic heart disease (IHD) is still high. Furthermore, this patient group is heterogenous; individuals with a higher risk of cardiovascular complications can be isolated from this group based on the presence of comorbidities and acute IHD on the background of the therapy. Such patients require a more aggressive treatment to influence major components of the increased risk. Even after administration of an optimum therapy, the risk for complications in such patients remains high (residual risk). The article discusses the lipid, inflammatory, and thrombotic components of residual risk in IHD patients and possibilities of their control with drugs with a special focus on possibilities of pharmaceutical correction of the risk thrombotic component in IHD patients with diabetes mellitus.

Abstract
Improvement in the prognosis of patients at risk of atherothrombotic events is based on three pillars - slowing down the process of atherogenesis (i.e. the development of atherosclerotic plaque), stabilizing the current atherosclerotic plaque, and reducing the risk of thrombotic occlusion in cases with unstable atherosclerotic plaque. The current prophylaxis has so far taken into consideration the adjustment of several risk factors, including dyslipidemia, arterial hypertension, smoking, and diabetes through lifestyle changes or pharmacological therapies. An essential part of prophylaxis is the anti-thrombotic strategy, especially anti-platelet therapy. Recently, a new pathway has been developed, based on reducing the activity of the inflammatory process with NLRP3 inflammasome, specifically a monoclonal antibody against interleukin 1beta (canakinumab). The efficacy and safety of this treatment, in secondary prevention, were documented in the CANTOS study. Other therapeutic procedures, including suppression of the inflammatory component of atherogenesis, are at the stage of clinical assessment.

A sandwich ELISA-like detection of C-reactive protein in blood by citicoline-bovine serum albumin conjugate and aptamer-functionalized gold nanoparticles nanozyme. Talanta 2020; 217:121070. [PMID: 32498852 DOI: 10.1016/j.talanta.2020.121070] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Revised: 04/18/2020] [Accepted: 04/20/2020] [Indexed: 12/11/2022]
Abstract
C-reactive protein (CRP) level in blood is associated with the risk of developing cardiovascular events in higher-risk populations. We present a sandwich ELISA-like assay for the determination of CRP in blood by citicoline-bovine serum albumin (citicoline-BSA) conjugate and aptamer-functionalized gold nanoparticles (aptamer-AuNPs) nanozyme. The CRP in the blood sample was selectively adsorbed to the ELISA plate coated by citicoline-BSA, and then incubated with added aptamer-AuNPs. AuNPs exhibited peroxidase activity and oxidized 3,3'5,5'-tetramethylbenzidine from colorless to blue, achieving the measurement at 652 nm. The amplified signal increased linearly in a wide range from 0.1 to 200 ng mL-1 and with a detection limit of 8 pg mL-1. Finally, the method was further tested using rat blood from an isoproterenol-induced myocardial infarction experimental model to confirm its applicability. The developed method could directly determine CRP in blood sample after dilution with high accuracy and sensitivity. This method has many advantages, such as easiness to prepare materials, good stability between batches, high specificity, low detection limit, low-cost, easiness to operate with simple instruments, the most remarkable of which is its excellent lot-to-lot stability over the classical ELISA.

Abstract
OBJECTIVE This study aims to investigate the role of endothelin-1 (ET-1) and C-reactive protein (CRP) in restenosis after intervention of lower extremity arteriosclerosis obliterans. METHODS The present prospective observational study included a total of 251 patients with arteriosclerosis obliterans in the lower extremity. All patients were treated with balloon dilatation, stent-assisted angioplasty or balloon dilatation, and stent-assisted angioplasty. Furthermore, these patients received a CTA examination at one and three months after surgery. The serum ET-1 and CRP levels were determined using a commercial enzyme-linked immunosorbent assay (ELISA). RESULTS In non-restenosis patients, both the CRP and ET-1 levels were significantly upregulated after surgery, reached a peak level at one week, and decreased at one month after surgery. However, for restenosis patients, the serum ET-1 and CRP levels did not decrease to the baseline at one and three months after surgery, but were remarkably higher than the levels for non-restenosis patients. Serum ET-1 levels were positively correlated with serum CRP levels at both one and three months after surgery. Both ET-1 and CRP levels after one week and one month, and CRP at three days, one week, one month and three months after surgery were risk factors for restenosis after intervention surgery of arteriosclerosis obliterans. CONCLUSION Both serum ET-1 and CRP levels were elevated after one and three months of intervention for lower extremity arteriosclerosis obliterans in patients with restenosis. These might be the risk factors for restenosis of lower extremity arteriosclerosis obliterans patients.

Abstract
Background Particulate matter (particles < 2.5 μm [ PM 2.5]) exposure during the in utero and postnatal developmental periods causes cardiac dysfunction during adulthood. Here, we investigated the potential priming effects of preconception exposure of PM 2.5 on cardiac function in adult offspring. Methods and Results Male and female friend leukemia virus b (FVB) mice were exposed to either filtered air ( FA ) or PM 2.5 at an average concentration of 38.58 μg/m3 for 6 hours/day, 5 days/week for 3 months. Mice were then crossbred into 2 groups: (1) FA male× FA female (both parents were exposed to FA preconception) and, (2) PM 2.5male× PM 2.5female (both parents were exposed to PM 2.5 preconception). Male offspring were divided: (1) preconception FA (offspring born to FA exposed parents) and, (2) preconception PM 2.5 (offspring born to PM 2.5 exposed parents) and analyzed at 3 months of age. Echocardiography identified increased left ventricular end systolic volume and reduced posterior wall thickness, reduced %fractional shortening and %ejection fraction in preconception PM 2.5 offspring. Cardiomyocytes isolated from preconception PM 2.5 offspring showed reduced %peak shortening, -dL/dT, TPS 90 and slower calcium reuptake (tau). Gene and protein expression revealed modifications in markers of inflammation ( IL -6, IL -15, TNF α, NF қB, CRP , CD 26E, CD 26P, intercellular adhesion molecule 1, and monocyte chemoattractant protein-1) profibrosis (collagen type III alpha 1 chain), oxidative stress ( NOS 2), antioxidants (Nrf2, SOD , catalase), Ca2+ regulatory proteins ( SERCA 2a, p- PLN , NCX ), and epigenetic regulators (Dnmt1, Dnmt3a, Dnmt3b, Sirt1, and Sirt2) in preconception PM 2.5 offspring. Conclusions Preconception exposure to PM 2.5 results in global cardiac dysfunction in adult offspring, suggesting that abnormalities during development are not limited to the prenatal or postnatal periods but can also be determined before conception.

Abstract
Aims The aim of this study was to examine whether high-sensitivity C-reactive protein (hs-CRP), N-terminal pro-brain natriuretic peptide (NT-proBNP), and soluble urokinase plasminogen activator receptor (suPAR) carried incremental prognostic value in predicting cardiovascular morbidity and mortality beyond traditional risk factors in apparently healthy individuals. Methods and results This was a prospective population-based cohort study comprising 1951 subjects included in the 10-year follow-up of the MONItoring of trends and determinants in CArdiovascular disease (MONICA) study, between 1993 and 1994. The principal endpoint was death from cardiovascular causes. Secondary endpoints were death from any cause, coronary artery disease, heart failure, and cerebrovascular disease. Predictive capabilities of each of the three biomarkers were tested using Cox proportional-hazards regression, Harrell’s concordance index (C-index), and net reclassification improvement (NRI). Study participants were aged 41, 51, 61, or 71 years, and equally distributed between the two sexes. During a median follow-up of 18.5 years (interquartile range: 18.1–19.0), 177 (9.1%) subjects died from a cardiovascular cause. Hs-CRP (adjusted standardized hazard ratio (HR): 1.37, 95% confidence interval (CI): 1.17–1.60), NT-proBNP (HR: 1.90, 95% CI: 1.58–2.29), and suPAR (HR: 1.35, 95% CI: 1.17–1.57) were all significantly associated with cardiovascular deaths after adjustment for age, sex, smoking status, systolic blood pressure, and total cholesterol ( p < 0.001 for all). Furthermore, all three biomarkers were significantly associated with significant NRI. However, only NT-proBNP significantly raised the C-index in predicting death from cardiovascular causes when added to the risk factors (C-index 0.860 versus 0.847; p = 0.02). Conclusions Hs-CRP, suPAR, and particularly NT-proBNP predicted cardiovascular death and may enhance prognostication beyond traditional risk factors in apparently healthy individuals.

Modifiable lifestyle risk factors and C-reactive protein in patients with coronary artery disease: Implications for an anti-inflammatory treatment target population. Eur J Prev Cardiol 2019; 28:152–158.

Abstract
BACKGROUND Modifiable lifestyle risk factors (modRF) of coronary artery disease (CAD) are associated with increased inflammation represented by elevated C-reactive protein (CRP) levels. Lifestyle changes may influence the inflammatory burden in patients with CAD, relevantly modifying the target population for emerging anti-inflammatory compounds. AIMS The aims of this study were to analyse the association of modRF and CRP levels in CAD patients, and to define a potential target population for anti-inflammatory treatment with and without the optimisation of modRF. METHODS We included all patients with angiographically documented CAD from the observational cohort study INTERCATH. Patients with recent myocardial infarction, malignancy, infectious disease, and pre-existing immunosuppressive medication including a history of solid organ transplantation were excluded. Overweight (body mass index (BMI) ≥ 25 kg/m2), smoking, lack of physical activity (PA; <1.5 h/week), and poor diet (≤12 points of an established Mediterranean diet score (MDS), range 0-28 points) were considered as modRF. CRP was measured by a high-sensitivity assay (hsCRP) at baseline. We performed multivariable linear regressions with log-transformed hsCRP as the dependent variable. Based on these associations, we calculated potential hsCRP levels for each patient, assuming optimisation of the individual modRF. RESULTS Of 1014 patients, 737 (73%) were male, the mean age was 69 years, and 483 (48%) had an hsCRP ≥ 2 mg/l. ModRF were significantly overrepresented in patients with hsCRP ≥ 2 mg/l compared to patients with an hsCRP < 2 mg/l (BMI ≥ 25 kg/m2: 76% vs 61%; PA < 1.5 h/week: 69% vs 57%; MDS ≤ 12: 46% vs 37%; smoking: 61% vs 54%; p < 0.05 for all). hsCRP increased with the incremental number of modRF present (median hsCRP values for N = 0, 1, 2, 3, and 4 modRF: 1.1, 1.0, 1.6, 2.4, 2.8 mg/l, p < 0.001). Multivariable linear regression adjusting for age, sex, intake of lipid-lowering medication, and diabetes mellitus revealed independent associations between log-transformed hsCRP and all modRF (BMI ≥ 25 kg/m2: exp(ß) = 1.55, p < 0.001; PA < 1.5 h/week: exp(ß) = 1.33, p < 0.001; MDS ≤ 12: exp(ß) = 1.18, p = 0.018; smoking: exp(ß) = 1.18, p = 0.019). Individual recalculation of hsCRP levels assuming optimisation of modRF identified 183 out of 483 (38%) patients with hsCRP ≥ 2 mg/l who could achieve an hsCRP < 2 mg/l via lifestyle changes. CONCLUSION modRF are strongly and independently associated with CRP levels in patients with CAD. A relevant portion of CAD patients with high inflammatory burden could achieve an hsCRP < 2 mg/l by lifestyle changes alone. This should be considered both in view of the cost and side-effects of pharmacological anti-inflammatory treatment and for the design of future clinical trials in this field.

Identification of a blood-based 12-gene signature that predicts the severity of coronary artery stenosis: An integrative approach based on gene network construction, Support Vector Machine algorithm, and multi-cohort validation. Atherosclerosis 2019; 291:34-43. [PMID: 31689620 DOI: 10.1016/j.atherosclerosis.2019.10.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 09/25/2019] [Accepted: 10/08/2019] [Indexed: 01/22/2023]
Abstract
BACKGROUND AND AIMS We aimed to identify a blood-based gene expression score (GES) to predict the severity of coronary artery stenosis in patients with known or suspected coronary artery disease (CAD) by integrative use of gene network construction, Support Vector Machine (SVM) algorithm, and multi-cohort validation. METHODS In the discovery phase, a public blood-based microarray dataset of 110 patients with known CAD was analyzed by weighted gene coexpression network analysis and protein-protein interaction network analysis to identify candidate hub genes. In the training set with 151 CAD patients, bioinformatically identified hub genes were experimentally verified by real-time polymerase chain reaction, and statistically filtered with the SVM algorithm to develop a GES. Internal and external validation of GES was performed in patients with suspected CAD from two validation cohorts (n = 209 and 206). RESULTS The discovery phase screened 15 network-centric hub genes significantly correlated with the Duke CAD Severity Index. In the training cohort, 12 of 15 hub genes were filtered to construct a blood-based GES12, which showed good discrimination for higher modified Gensini scores (AUC: 0.798 and 0.812), higher Sullivan Extent scores (AUC: 0.776 and 0.778), and the presence of obstructive CAD (AUC: 0.834 and 0.792) in two validation cohorts. A nomogram comprising GES12, smoking status, hypertension status, low density lipoprotein cholesterol level, and body mass index further improved performance, with respect to discrimination, risk classification, and clinical utility, for prediction of coronary stenosis severity. CONCLUSIONS GES12 is useful in predicting the severity of coronary artery stenosis in patients with known or suspected CAD.

Abstract
Introduction Hematological indices including red cell distribution width and neutrophil to lymphocyte ratio are proven to be associated with outcomes of acute coronary syndrome. The usefulness of machine learning techniques in predicting mortality after acute coronary syndrome based on such features has not been studied before. Objective We aim to create an alternative risk assessment tool, which is based on easily obtainable features, including hematological indices and inflammation markers. Patients and Methods We obtained the study data from the electronic medical records of 5053 patients hospitalized with acute coronary syndrome during a 5-year period. The time of follow-up ranged from 12 to 72 months. A machine learning classifier was trained to predict death during hospitalization and within 180 and 365 days from admission. Our method was compared with the Global Registry of Acute Coronary Events (GRACE) Score 2.0 on a test dataset. Results For in-hospital mortality, our model achieved a c-statistic of 0.89 while the GRACE score 2.0 achieved 0.90. For six-month mortality, the results of our model and the GRACE score on the test set were 0.77 and 0.73, respectively. Red cell distribution width (HR 1.23; 95% CL 1.16-1.30; P < 0.001) and neutrophil to lymphocyte ratio (HR 1.08; 95% CL 1.05-1.10; P < 0.001) showed independent association with all-cause mortality in multivariable Cox regression. Conclusions Hematological markers, such as neutrophil count and red cell distribution width have a strong association with all-cause mortality after acute coronary syndrome. A machine-learned model which uses the abovementioned parameters can provide long-term predictions of accuracy comparable or superior to well-validated risk scores.
