Abstract
Lipidomics emerges as a promising research field with the potential to help in personalized risk stratification and improve our understanding on the functional role of individual lipid species in the metabolic perturbations occurring in coronary artery disease (CAD). This study aimed to utilize a machine learning approach to provide a lipid panel able to identify patients with obstructive CAD. In this posthoc analysis of the prospective CorLipid trial, we investigated the lipid profiles of 146 patients with suspected CAD, divided into two categories based on the existence of obstructive CAD. In total, 517 lipid species were identified, from which 288 lipid species were finally quantified, including glycerophospholipids, glycerolipids, and sphingolipids. Univariate and multivariate statistical analyses have shown significant discrimination between the serum lipidomes of patients with obstructive CAD. Finally, the XGBoost algorithm identified a panel of 17 serum biomarkers (5 sphingolipids, 7 glycerophospholipids, a triacylglycerol, galectin-3, glucose, LDL, and LDH) as totally sensitive (100% sensitivity, 62.1% specificity, 100% negative predictive value) for the prediction of obstructive CAD. Our findings shed light on dysregulated lipid metabolism's role in CAD, validating existing evidence and suggesting promise for novel therapies and improved risk stratification.

Abstract
The effects of Bacillus spp. (7 Log CFU g-1 feed) and fructooligosaccharide (FOS, 1%) as functional feed additives, either alone or in combination, were evaluated in a study on rohu, Labeo rohita fingerlings. The fish were fed different diets for 90 days, including a control diet and diets supplemented with FOS, B. licheniformis, B. methylotrophicus or synbiotic formulations of these. The results showed that the combination of B. licheniformis and FOS significantly improved weight gain, feed utilisation and protease activity compared to the other groups. Overall, the groups supplemented with probiotics and synbiotics (B. licheniformis + FOS or B. methylotrophicus + FOS) showed improvements in haematology, serum biochemistry and immune parameters compared to the control group. After 90 days of experimental feeding, the fish were challenged with pathogenic Aeromonas hydrophila, and data on haematology, immunity and stress parameters were collected. The results indicated that the application of Bacillus spp. and FOS boosted immunity and resistance to physiological stress in the fish. The highest post-challenge survival rate was observed in fish fed a diet with B. licheniformis and FOS, indicating the potential of this particular combination of functional feed additives to enhance growth, immunity and disease resistance in L. rohita.

Abstract
Existing studies could not separate the effects of heavy metal exposure on cardiovascular disease (CVD) risk from those caused by physical activity (PA). The possible interactive effect of heavy metal exposure and PA on the risk of CVD remains still unknown. We enrolled a total of 12,280 participants in 2007-2018 cycles of the U.S. National Health and Nutrition Examination Survey (NHANES) and discovered that both low blood concentrations of Cd and Pb were positively correlated with increased prevalence of CVD and subtypes, with a stronger association for blood Cd than Pb. Negative dose-response relationships between PA and the prevalence of CVD and subtypes were identified. Participants with inactive and active PA had lower risk of CVD than those having no PA, with multivariate adjusted ORs 0.8 (95% CI: 0.69, 0.94) and 0.76 (95% CI: 0.68, 0.85), respectively. The only evidence for negative interaction between regular PA and blood Cd concentrations was found with regard to the prevalence of CVD and subtypes, indicating that regular PA could well modify the adverse effect of blood Cd on CVD risk. We demonstrate for the first time to date that PA may have a beneficial effect against the hazardous impact of Cd exposure on elevated CVD risk, emphasizing the necessity to promote a healthy lifestyle with active PA.

Cellular mechanisms and molecular pathways linking bitter taste receptor signalling to cardiac inflammation, oxidative stress, arrhythmia and contractile dysfunction in heart diseases. Inflammopharmacology 2023; 31:89-117.

Abstract
Heart diseases and related complications constitute a leading cause of death and socioeconomic threat worldwide. Despite intense efforts and research on the pathogenetic mechanisms of these diseases, the underlying cellular and molecular mechanisms are yet to be completely understood. Several lines of evidence indicate a critical role of inflammatory and oxidative stress responses in the development and progression of heart diseases. Nevertheless, the molecular machinery that drives cardiac inflammation and oxidative stress is not completely known. Recent data suggest an important role of cardiac bitter taste receptors (TAS2Rs) in the pathogenetic mechanism of heart diseases. Independent groups of researchers have demonstrated a central role of TAS2Rs in mediating inflammatory, oxidative stress responses, autophagy, impulse generation/propagation and contractile activities in the heart, suggesting that dysfunctional TAS2R signalling may predispose to cardiac inflammatory and oxidative stress disorders, characterised by contractile dysfunction and arrhythmia. Moreover, cardiac TAS2Rs act as gateway surveillance units that monitor and detect toxigenic or pathogenic molecules, including microbial components, and initiate responses that ultimately culminate in protection of the host against the aggression. Unfortunately, however, the molecular mechanisms that link TAS2R sensing of the cardiac milieu to inflammatory and oxidative stress responses are not clearly known. Therefore, we sought to review the possible role of TAS2R signalling in the pathophysiology of cardiac inflammation, oxidative stress, arrhythmia and contractile dysfunction in heart diseases. Potential therapeutic significance of targeting TAS2R or its downstream signalling molecules in cardiac inflammation, oxidative stress, arrhythmia and contractile dysfunction is also discussed.

Abstract
Since December 2019, the COVID-19 pandemic has affected the global population, and one of the major causes of mortality in infected patients is cardiovascular diseases (CVDs).For this systematic review and meta-analysis, we systematically searched Google Scholar, Scopus, PubMed, Web of Science, and Cochrane databases for all articles published by April 2, 2020. Observational studies (cohort and cross-sectional designs) were included in this meta-analysis if they reported at least one of the related cardiovascular symptoms or laboratory findings in COVID-19 patients. Furthermore, we did not use any language, age, diagnostic COVID-19 criteria, and hospitalization criteria restrictions. The following keywords alone or in combination with OR and AND operators were used for searching the literature: "Wuhan coronavirus", "COVID-19", "coronavirus disease 2019", "SARS-CoV-2", "2019 novel coronavirus" "cardiovascular disease", "CVD", "hypertension", "systolic pressure", "dyspnea", "hemoptysis", and "arrhythmia". Study characteristics, exposure history, laboratory findings, clinical manifestations, and comorbidities were extracted from the retrieved articles. Sixteen studies were selected which involved 4754 patients, including 2103 female and 2639 male patients. Among clinical cardiac manifestations, chest pain and arrhythmia were found to have the highest incidence proportion. In addition, elevated lactate dehydrogenase (LDH) and D-dimer levels were the most common cardiovascular laboratory findings. Finally, hypertension, chronic heart failure, and coronary heart disease were the most frequently reported comorbidities. The findings suggest that COVID-19 can cause various cardiovascular symptoms and laboratory findings. It is also worth noting that cardiovascular comorbidities like hypertension have a notable prevalence among COVID-19 patients.

Abstract
COVID-19 has become a global health concern, due to the high transmissible nature of its causal agent and lack of proper treatment. Early diagnosis and nonspecific medical supports of the patients appeared to be effective strategy so far to combat the pandemic caused by COVID-19 outbreak. Biomarkers can play pivotal roles in timely and proper diagnosis of COVID-19 patients, as well as for distinguishing them from other pulmonary infections. Besides, biomarkers can help in reducing the rate of mortality and evaluating viral pathogenesis with disease prognosis. This article intends to provide a broader overview of the roles and uses of different biomarkers in the early diagnosis of COVID-19, as well as in the classification of COVID-19 patients into multiple risk groups.

Abstract
INTRODUCTION Recent studies have reported evidence that coronavirus disease 2019 (COVID-19) has disproportionately affected patients with underlying comorbidities. Our study aims to evaluate the impact of both cardiac and noncardiac comorbidities on a high-risk population with COVID-19 infection and coronary artery disease (CAD) compared to those without CAD. METHODS This is a retrospective study of patients who tested COVID-19 positive via reverse transcriptase-PCR (RT-PCR) assay. We compared the characteristics and outcomes of patients with and without CAD. Population demographics, comorbidities and clinical outcomes were collected and analyzed. Multivariate logistic regression analysis was used to identify factors associated with inpatient mortality. RESULTS A final sample population of 355 patients was identified, 77 of which had a known diagnosis of coronary artery disease. Our study population had a higher proportion of females, and those with CAD were significantly older. The rates of cardiovascular risk factors including hypertension, diabetes mellitus and chronic kidney disease, as well as heart failure and chronic obstructive pulmonary disease were significantly higher in the CAD population. Lactate dehydrogenase was the only inflammatory marker significantly lower in the CAD group, while troponin and brain natriuretic peptide were significantly higher in this population. Patients with CAD also had significantly higher inpatient mortality (31% vs 20%, P = 0.046) and need for renal replacement therapy (33% vs 11%, P < 0.0001) compared to the non-CAD group. However, only age [odds ratio 1.041 (1.017-1.066), P = 0.001] was significantly associated with mortality in the overall population after adjusting for demographics and comorbidities, while the presence of CAD was not independently associated with mortality. CONCLUSION Patients with CAD and COVID-19 have higher rates of comorbidities, inpatient mortality and need for renal replacement therapy compared to their non-CAD counterparts. However, CAD in itself was not associated with mortality after adjusting for other covariates, suggesting that other factors may play a larger role in the increased mortality and poor outcomes in these patients.

Abstract
Objective A previous study revealed a pronounced protective effect of combining quercetin (QC) with sitagliptin (STN) in testicular tissue. Accordingly, this study was designed to evaluate the cardioprotective effects of QC and STN each alone or in combination in doxorubicin (DOX)-induced cardiotoxicity in the rats. Methodology Thirty male adult Wistar rats were divided into five groups: the first group (control) treated with sodium chloride, the second group treated with DOX (3 mg/kg I.P. injection), the third group treated with DOX with a combination of QC (80 mg/kg), and STN (10 mg/kg), the fourth group treated with DOX and QC and the fifth group treated with DOX and STN. Blood was collected on day 22 and used for assessment of serum troponin, lactate dehydrogenase (LDH), creatine phosphokinase (CPK), total lipid profile, C-reactive protein (CRP), and total antioxidant capacity (TAOC). Atherogenic indices were also calculated. Cardiac tissue was sent for histopathological analysis. Results DOX produced a significant increase in the level of troponin, LDH, CKP, CRP, total cholesterol (TC), low-density lipoprotein (LDL), triglycerides (TG), and atherogenic index of plasma; and significantly decreased TAOC. The combination of quercetin and sitagliptin was more effective than each treatment alone in restoring the level of troponin, LDH, CKP, CRP, Cholesterol, LDL, TG, atherogenic index of plasma and significantly increased TAOC compared to DOX treated group. The histopathological finding also supports the biochemical results. Conclusion The study revealed the cardioprotective effects of the combination of QC and STN which could be attributed to the additive effects of this combination through antioxidant, anti-inflammatory, lipid lowering and anti-atherogenic activities; suggesting it as a good therapeutic candidate to be tested in the clinical setting.

Abstract
OBJECTIVES Ischemic heart failure (IHF) is the most common cause of death globally. Growing evidence shows abnormal expression of long non-coding RNAs in heart failure patients. This study aims to investigate the effect of sex-determining region Y-box 2 (SOX2) overlapping transcript (SOX2-OT) on the regulation of the inflammatory response in ischemic heart failure. METHODS IHF rat and oxygen and glucose deprivation (OGD) cell models were established. qRT-PCR was employed to investigate the expression of SOX2-OT. ELISA, western blot and cell viability/apoptosis assays were performed to assess the effects of SOX2-OT. Online software program was used to identify miRNAs that target SOX2-OT, followed by validation using RNA pull-down. Potential targets of miRNAs were searched, and examined by immunoblotting, qRT-PCR and luciferase reporter assay. RESULTS SOX2-OT was up-regulated in IHF and OGD. Knockdown of SOX2-OT promoted cell proliferation, decreased apoptosis rate and cell oxidative damage, and ameliorated inflammatory response. SOX2-OT contains binding sites for miR-455-3p, miR-5586-3p and miR-1252-5p. RNA pull-down confirmed the binding ability between SOX2-OT and miR-455-3p. TRAF6 is a direct target of miR-455-3p. Moreover, the regulatory activity of SOX2-OT on inflammatory response was partially through its negative regulation of miR-455-3p, which directly regulates TRAF6. Down-regulation of SOX2-OT improved myocardial dysfunction in IHF rat. CONCLUSIONS Our results reveal that SOX2-OT may be a driver of IHF through repression of miR-455-3p, and miR-455-3p alleviates IHF by targeting TRAF6. Therefore, SOX2-OT/miR-455-3p/TRAF6 may be a potential target for advanced therapeutic strategy for IHF.

Abstract
The Chinese patent medicine She-Xiang-Xin-Tong-Ning (SXXTN) is a clinical medication for coronary heart disease (CHD) and angina pectoris. This study aimed to investigate pharmacological effects of SXXTN and elucidate the role in angiogenesis on human umbilical vein endothelial cells (HUVECs) and acute myocardial ischemia (AMI) rats. We prepared SXXTN to treat the cells to reveal their effects on oxidative stress-damaged cell viability, as well as cell proliferation, migration, and tube formation processes. SXXTN was also used to treat coronary artery ligation-induced acute myocardial ischemia rats to confirm whether it had positive effect on myocardial issues by hematoxylin and eosin (HE), 2,3,5-triphenyltetrazolium chloride (TTC) staining and immunohistochemical staining. We measured the levels of peroxidative damage-related enzymes in cytoplasm and serum by biochemical kits and detected vascular endothelial growth factor (VEGF), angiotensin II (Ang II), thromboxane B2 (TXB2), and 6-keto-prostaglandin F1 alpha (6-keto-PGF1[Formula: see text]) levels in cells and rats by enzyme-linked immunosorbent assay (ELISA) kits. The results showed that SXXTN protects HUVECs against oxidative stress damage and reversed the decrease of superoxide dismutase (SOD), glutathione (GSH) and increase of creatine kinase (CK), lactate dehydrogenase (LDH) caused by oxidative stress. SXXTN promoted angiogenesis through stimulating cell migration, tube formation, and activating VEGF/VEGFR2 and ERK1/2 pathways. Furthermore, SXXTN reduced infarct size and inhibited PGI2/TXA2 imbalance, preventing atherosclerosis plaque rupture leading to worsening coronary heart disease. Taken together, we report the first in vivo and in vitro evidence that SXXTN reduced oxidative stress-mediated damage and enhanced angiogenesis, which might be useful in treatment of myocardial infarction.

Abstract
OBJECTIVES Recent research demonstrates that lactate dehydrogenase (LDH) activity within the normal range may serve as a mediator in the (positive) relationship between physical activity and cardiovascular disease risk. Emerging work supports deleterious associations between sedentary behavior and health, independent of physical activity. Thus, this study evaluated if sedentary behavior was associated with normal-range LDH activity, independent of physical activity. METHODS Data from the 2003-2006 NHANES were used (N = 2,087 adults; 40-79 yrs). LDH activity levels were estimated from a blood sample using LX20 and LDH reagent; participants were included if they had LDH activity levels within the normal range (105-333 IU/L). Physical activity and sedentary behavior were assessed via accelerometry. RESULTS Sedentary behavior was inversely associated with normal-range LDH activity when physical activity was excluded from the model (OR = 0.89; 95% CI: 0.83-0.97, P = 0.009 for LDH activity quartile 4 vs. 1). However, sedentary behavior was no longer associated with normal-range LDH activity after controlling for physical activity and other covariates (OR = 1.00, P = 0.49 for LDH activity quartile 2 vs. 1; OR = 1.00, P = 0.72 for LDH quartile 3 vs. 1; and OR = 0.99, P = 0.36 for LDH quartile 4 vs. 1). CONCLUSION Unlike physical activity, sedentary behavior is not independently associated with normal-range LDH activity.

Abstract
SCOPE Endothelial dysfunction and inflammation are both common events occurring during the development of atherosclerosis. Previous studies have shown that urolithins, the intestinal microflora metabolites of ellagitannin, exhibit anti-inflammation and antioxidative properties. This study aims to investigate the protective effect of urolithin A (UA) on ox-LDL-induced (where ox-LDL is oxidized low-density lipoprotein) endothelial dysfunction and possible modes of action. METHODS AND RESULTS Human artery endothelial cells were incubated with 50 μg/mL ox-LDL and various concentrations of UA for 24 h. UA improved the productions of nitric oxide and endothelial nitric oxide synthase in a dose-dependent manner. UA markedly reduced the expressions of ICAM-1 (intercellular adhesion molecule 1) and MCP-1 (monocyte chemotactic protein 1) and further attenuated THP-1 (human acute monocytic leukemia cell line) cell adhesion. In addition, UA suppressed expressions of tumor necrosis factor α, interleukin 6, and endothelin 1, and increased PPAR-γ (peroxisome proliferators activated receptor gamma) mRNA expression. Moreover, UA decreased miR-27 expression, and overexpression of miR-27 by adding pre-miR-27 abolished the ability of UA to improve ox-LDL-induced PPAR-γ decrease. Furthermore, UA significantly downregulated phosphorylated ERK1/2 (where ERK is extracellular signal-regulated kinase) while decreasing interleukin 6 level and elevating PPAR-γ. CONCLUSIONS UA could alleviate endothelial dysfunction induced by ox-LDL partially through modulating miR-27 expression and ERK/PPAR-γ pathway.

Abstract
BACKGROUND Left ventricular (LV) diastolic dysfunction (LVDD) is a well-established and early echocardiographic characteristic of diabetic cardiomyopathy. However, there are limited data on the association between impaired fasting glucose (IFG) and LVDD. OBJECTIVE To determine whether IFG is associated with LVDD among middle age adults. METHODS Amongst 3781 subjects screened in an annual health survey program and referred for an echocardiogram, 2971 individuals without LV systolic dysfunction or valvular heart disease were selected. Mean age of study population was 59 ± 12 years and 75% were men. The subjects were categorized into three groups: euglycemia (N = 2025), IFG (N = 534) and diabetes mellitus (DM; N = 412). Doppler echocardiography readers were blinded to glycemic state. Subjects with impaired LV relaxation, pseudo-normal or restrictive filling patterns were defined as having LVDD. RESULTS LVDD was diagnosed in 574 (19 %) of subjects and it was more prevalent among patients with IFG and DM than in euglycemic individuals (27, 30 and 15%, respectively; p < 0.001). Patients with IFG and DM had lower ratios of early (E) to late (A) trans-mitral flow (0.9 ± 0.3 and 0.9 ± 0.3 vs. 1.1 ± 0.4, respectively, p < 0.001). LV hypertrophy (LVH) was also more prevalent among patients with IFG and DM (11 and 18%, respectively, vs. 9%; p < 0.001). Multivariate binary logistic regression model adjusted to age, gender, obesity, LVH, renal function, total, high and low density lipoprotein cholesterol, triglycerides, ischemic heart disease, hypertension and LV ejection fraction showed that patients with IFG were 43% more likely to have LVDD compared with euglycemic subjects (95% confidence interval 1.12-1.83, p = 0.004). CONCLUSIONS IFG is independently associated with a significant increase in the likelihood for the presence of LVDD in middle aged adults.

Abstract
BACKGROUND We aimed to evaluate whether reduced cardiovascular fitness has a direct or indirect effect for the development of cardiovascular disease. METHODS We investigated 15,595 men and women who were annually screened in a tertiary medical center. All subjects were free of ischemic heart disease and had completed maximal exercise stress test according to the Bruce protocol at their first visit. Fitness was categorized into age- and sex-specific quintiles (Q) according to Bruce protocol treadmill time with Q1 as lowest fitness. Subjects were categorized at baseline into 3 groups: low fitness (Q1), moderate fitness (Q2-Q4), and high fitness (Q5). The primary end point of the current analysis was the development of a first cardiovascular event during follow-up. RESULTS Mean age of study patients was 48 ± 10 years, and 73% were men. A total of 679 events occurred during 92,092 person-years of follow-up. Kaplan-Meier survival analysis showed that the cumulative probability of cardiovascular events at 6 years was significantly higher among subjects with low fitness (P < .001). Low fitness was associated with known cardiovascular risk factors, including hypercholesterolemia (odds ratio [OR] 1.58, 95% CI 1.31-1.89), diabetes mellitus (OR 2.32, 95% CI 1.58-3.41), and obesity (OR 10.46, 95% CI 8.43-12.98). The effect of low fitness on cardiovascular events was no longer significant when including diabetes mellitus, hypercholesterolemia, and obesity as mediators (hazard ratio 0.99, 95% CI 0.82-1.19). CONCLUSIONS The association between cardiovascular fitness and adverse cardiovascular outcomes may be modulated through traditional cardiovascular risk factors. These findings need to be further validated in prospective clinical trials.

Abstract
Ischemic heart disease (IHD) is the leading cause of death worldwide and remains a major life-threatening factor in humans. Apoptosis has been implicated in the pathogenesis of IHD. The Chinese herbal formula Huo Luo Xiao Ling Dan (HLXLD), one of the commonly used Chinese herbal formulas, consists of Salviae miltiorrhizae, Angelica sinensis, Gummi olibanum, and Commiphora myrrha, with a wide spectrum of pharmacological activity. However, the mechanism of action and molecular targets of HLXLD in the treatment of IHD are unclear. This study aimed to computationally predict the molecular interactions between the major active components of HLXLD and key regulators of apoptosis and then examine the effect of HLXLD on coronary artery ligation-induced acute myocardial ischemia in rats. The molecular interactions between the major active components of HLXLD, including ferulic acid, ligustilide, succinic acid, vanillic acid, tanshinone IIA, tanshinone IIB, danshensu, salvianolic acid A, salvianolic acid C, protocatechuic aldehyde, and β-boswellic acid and human protein molecules including B cell lymphoma-extra large (Bcl-xl), B cell lymphoma 2 antagonist/killer 1 (Bak1), B cell lymphoma 2 (Bcl-2), procaspase 3, and caspase 9 with regard to hydrogen bond formation, charge interaction, and π-π stacking using Discovery Studio(®) program 3.1. The 12 HLXLD components were predicted by ADMET (absorption, distribution, metabolism, excretion and toxicity) Predictor to have favorable pharmacokinetic and low hepatotoxicity profiles. The acute myocardial ischemia was established by surgical ligation of the left anterior descending coronary artery. The rats were divided into a sham operative group, a model group, a positive control group treated with 0.2 mg/kg isosorbide mononitrate, and groups treated with 2.7, 5.4, or 10.8 g/kg HLXLD. The results showed that administration of HLXLD increased mean arterial pressure, left ventricular systolic pressure, heart rate, and maximal rate of rise/descent of left ventricular pressure levels. Administration of HLXLD significantly ameliorated coronary artery ligation-induced tissue damage in the left ventricle, with restored arrangement of myocardial fibers and recovered myoplasm in rats. Furthermore, HLXLD markedly increased the expression level of Bcl-2 but decreased the level of cleaved caspase 3. Taken together, administration of HLXLD attenuated acute myocardial ischemia-induced damage in cardiomyocytes and inhibited apoptotic death of cardiomyocytes, thereby exerting a cardioprotective effect in rats with IHD. These findings suggest that HLXLD may represent a promising herbal formula for the treatment of cardiovascular disease by counteracting apoptotic cell death via multiple active compounds. More studies are warranted to fully elucidate the mechanisms of action, identify the therapeutic targets, and validate the efficacy and safety of HLXLD in the treatment of IHD.

Abstract
BACKGROUND High-density lipoprotein cholesterol (HDL-C) is a strong inverse predictor of cardiovascular events. The aim of the current study was to evaluate the correlation between changes in HDL-C and subsequent cardiovascular events. METHODS Study population comprised 13,037 subjects free of cardiovascular disease with a mean follow up of 6 ± 3 years. Low HDL-C was defined as < 40 mg/dl for men and <50mg/dl for women. Participants were divided into three groups based on HDL-C levels at the first and second baseline visits: persistently-low HDL-C (LL); persistently-high HDL-C (HH); and those with high HDL-C in a one visit only: intermittently high HDL-C (LH/HL). The primary endpoint was the first occurrence of a cardiovascular event. RESULTS A total of 529 (4.1%) incident events occurred during follow-up. HDL-C levels increased significantly between the two landmark visits (47.5 ± 12.6 vs. 48.1 ± 12.2, p<0.001). Kaplan-Meier survival analysis showed that the cumulative probability of cardiovascular events at 6 years was highest among subjects in the LL group (7.6%), and similar among LH/HL and HH groups (3.3% and 4%, respectively; log-rank p=0.001). Multivariate Cox regression analysis, with HDL-C as time-dependent covariate, showed that subjects with persistently low HDL-C during follow up experienced a 51% increased cardiovascular risk compared with subjects with persistently high HDL-C (p=0.026). Subjects with intermittently high HDL-C during follow up experienced similar risk to those with persistently high HDL-C (HR=1.02; p=0.89). CONCLUSIONS Variations in HDL-C levels during follow-up are associated with subsequent cardiovascular risk. Patients who retain low HDL-C levels are at the cardiovascular highest risk.

Abstract
BACKGROUND Clinical thyroid disease is associated with changes in the cardiovascular system, including changes in heart rate during exercise. However, data on the relation between subclinical thyroid disease (SCTD) and heart rate during exercise are limited. METHODS We investigated 3799 apparently healthy subjects who were evaluated in the Institute for Preventive Medicine at the Sheba Medical Center. All subjects answered standard health questionnaires; were examined by a physician; completed routine blood tests including thyrotropin, free triiodothyronine, and free thyroxine levels; and underwent a treadmill exercise according to the Bruce protocol. Subjects with known thyroid disease or those who were taking thyroid-related drugs were excluded from the analysis. Heart rate profile was compared between patients with subclinical hypothyroidism (SCHypoT), patients with normal thyroid function, and patients with subclinical hyperthyroidism (SCHyperT) using propensity score matching. RESULTS Seventy patients had SCHyperT and 273 had SCHypoT. Compared with age- and sex-matched normal subjects, SCHyperT subjects had a higher resting heart rate (83±17 vs. 76±12 beats per minute [bpm], p=0.006), a significantly higher recovery heart rate (94±12 vs. 90±12 bpm, p=0.045), and a significantly lower heart rate reserve (80±20 vs. 87±18 bpm, p=0.006). Subjects with SCHypoT showed a trend toward a lower resting heart rate (75±13 vs. 77±15 bpm, p=0.09) and had a significantly lower recovery heart rate (88±12 vs. 90±13 bpm, p=0.035). There was no significant difference in exercise duration or blood pressure between subjects with SCTD and their matched normal controls. CONCLUSIONS Subjects with SCTD have a significantly different heart rate profile during rest, exercise, and recovery.

Abstract
OBJECTIVE Previous studies have demonstrated an association between increased serum uric acid (SUA) levels and incident diabetes. Most clinical and epidemiological investigations, however, focused solely on male populations or did not analyze men and women separately. We assessed the association between SUA levels and diabetes incidence in a large cohort of apparently healthy men and women. METHODS Data were retrospectively gathered from 9140 adults who participated in annual medical screening visits during 2000-2009. Mean follow-up time was 4.8 years, and the median age was 50 years. Laboratory test results, data from physical examinations, medical history, and lifestyle information were extracted. The main outcome measure was incident diabetes, defined as two consecutive fasting glucose tests higher than 125 mg/dL. Cox proportional-hazards multivariate models were applied for measuring hazard ratios (HRs) for diabetes according to continuous and categorical levels of uric acid. RESULTS We identified 499 new cases of diabetes (total, 5.5%: men, 6.2%; women, 3.6%) during the follow-up period. The gender-specific HRs for diabetes, adjusted for age and a set of prespecified multiple risk and protective factors, were 1.57 for each 1 mg/dL increase in SUA (95% confidence interval [CI], 1.32-1.86) in women and 1.08 (95% CI, 0.99-1.17) in men; p for interaction of SUA by gender <0.001. CONCLUSION SUA is independently associated with diabetes outcome, considerably more in women than in men.

Abstract
Studies in different populations with high risk for cardiovascular disease (CVD) have shown an association between serum uric acid (SUA) and CVD. However, only a few studies have demonstrated such an association in healthy populations. The aim of this study was to investigate the association between SUA and CVD in a cohort of men and women without diabetes or CVD. A retrospective study was conducted, with a mean 4.8-year follow-up. The outcome was the occurrence of a cardiovascular event, defined as the diagnosis of ischemic heart disease, acute coronary syndrome, acute myocardial infarction, or ischemic stroke. Mean SUA levels were 6.2 ± 1.1 mg/dl for men (n = 6,580) and 4.4 ± 1.1 mg/dl for women (n = 2,559). For women, the rate of CVD occurrence was 11.6% for the highest quartile of SUA level, compared with 5.0% to 6.5% for the lower 3 quartiles. For men, the rate of CVD occurrence was 14.0% for the highest quartile of SUA level, compared with 10.8% for the lowest quartile. The hazard ratio for CVD, adjusted for age, serum creatinine level, body mass index, systolic blood pressure, low-density lipoprotein cholesterol level, triglyceride level, plasma fasting glucose, physical activity, cardiovascular family history, use of diuretics, and current smoking, was 1.24 (95% confidence interval 1.08 to 1.41) for women and 1.06 (95% confidence interval 1.00 to 1.13) for men (p for interaction = 0.04). In conclusion, the strong association of SUA levels with CVD in women, compared with the much lesser degree in men, highlights the necessity of stratifying by gender in investigations of cardiovascular risk factors and supports exploration of SUA as a marker of CVD risk in healthy populations.
