Introduction: Epicardial fat has been related to coronary artery disease (CAD) independent of visceral or subcutaneous fat. The mechanism responsible for this association has not yet been elucidated. Our objective was to evaluate the association between automatically measured epicardial fat volume (EFV), cardiovascular risk factors, coronary artery calcium (CAC) and endothelial function in participants of ELSA-Brasil. Methods and Results: The sample comprised 470 (mean age 55± 8y, 52.3% men) participants from ELSA-MG, one of the Investigation Centers of the cohort, who had valid computed tomography scans and endothelial function evaluated by peripheral arterial tonometry (PAT). The mean EFV was 111 (IQ 86-144) mL. CAC=0 was detected in 55% of participants. In the multivariable analyses between cardiovascular risk factors and EFV, the following associations were observed with higher EFV: female sex; and increased age, waist circumference and triglycerides (p <0.001 for all). In multivariable analyses, higher EFV remained associated with worse endothelial function - basal pulse amplitude (q2=1.22, CI95% 1.07-1.40, p=0.004; q3=1.50, CI95% 1.30-1.74, p<0.001; q4=1.50, CI95% 1.28-1.79, p<0.001) and PAT ratio (q2=0.87, CI95% 0.81-0.95, p<0.001; q3=0.86, CI95% 0.79-0.94, p<0.001; q4=0.80, CI95% 0.73-0.89, p<0.001), but not with CAC. Conclusions: Higher EFV was associated with impaired endothelial function, but not with higher CAC. Our results suggest that the mechanism by which epicardial fat deposits relates to CAD may be different from the pathway of CAC, which relates to calcified plaques. A possible mechanism may be through the enhancement of endothelial dysfunction, microvascular disease and predominantly lipidic non-calcified plaques.

Abstract Context: Cardiovascular risk factors are well-known predictors of the development of diabetic peripheral neuropathy (DPN), which has traditionally been considered as a manifestation of diabetes-associated microangiopathy. Because endothelial dysfunction is strongly associated with all cardiovascular risk factors, we hypothesized that it may be a link between cardiovascular risk factors and DPN. Objective: The primary objective of this study was to test whether endothelial dysfunction is a predictor of DPN. Design and Setting: This is a cross-sectional analysis of a cohort composed of patients followed at the Microcirculatory Laboratory, Beth Israel Deaconess Medical Center. Patients: Participants with diabetes without DPN (n = 192) and with DPN (n = 166), subjects with prediabetes (n = 75), and nondiabetic controls (n = 59) were included. Interventions: Endothelial function was assessed with flow-mediated dilation (FMD) of the brachial artery. Inflammatory cytokines and biomarkers of endothelial function (soluble intercellular and vascular cell adhesion molecules) were quantified using a multiplex bead-based immunoassay. Neurological assessment included the neuropathy disability score (NDS). Main Outcome Measure: The relationship between FMD and NDS assessed using multiple linear regression. Results: In addition to already known risk factors of DPN, FMD was strongly associated with NDS (β = −0.24; P &lt; .001). Sensitivity analysis that removed FMD from the model provided similar results for soluble intercellular cell adhesion molecule-1, another biomarker of endothelial function. Confirmatory factor analysis further showed that endothelial dysfunction is a significant mediator between glycosylated hemoglobin and diabetes duration and diabetic complications. Conclusions: This study shows that endothelial dysfunction occurs early in the pathophysiology of diabetes and is a link between cardiovascular risk factors and DPN.

Cardiovascular risk factors are known to exacerbate high-saturated fatty acid meal (HSFAM)-induced endothelial dysfunction, but the influence of subclinical metabolic dysregulations and the acute impact of a single mixed Mediterranean-type meal (MMM) remains unknown. Thus, this study has the objective to evaluate the metabolic and vascular effect of such meals in healthy subjects with or without subclinical fasting metabolic dysregulations. Twenty-eight healthy males without overt cardiovascular risk factors randomly ingested 1 of 2 isocaloric meals on separate days. Plasma metabolic markers, fatty acid (FA) profile, and endothelial function (flow-mediated dilatation; FMD) were assessed at baseline and 2 and 4 h after meal ingestion. Unsupervised hierarchical clustering identified 2 subgroups of participants (n = 11 and 17) differing by their baseline metabolic profiles. The MMM did not significantly alter postprandial endothelial function in all subjects, irrespective of baseline metabolic parameters. In contrast, the HSFAM induced postprandial endothelial dysfunction (Δ%FMDabsolute = −5.28 ± 2.54, p < 0.01 vs. MMM) in a subgroup of individuals with significantly greater body mass index, fasting insulinemia, and lipid parameters (n = 11). Finally, the postprandial plasma FA profiles were differentially enriched by the HSFAM and MMM, notably with saturated FAs and omega-3 polyunsaturated FAs, respectively. Collectively, our results highlight the detrimental impact of a single HSFAM on endothelial function in healthy individuals displaying subclinical fasting metabolic dysregulations. Such individuals could benefit from MMM, demonstrated herein to be without any acute detriment to endothelial function.

Background: Coronary artery disease (CAD) is the most frequent cause of ST-segment elevation myocardial infarction (STEMI). Etiopathogenic and prognostic characteristics in young patients may differ from older patients and young women may present worse outcomes than men. We aimed to evaluate the clinical characteristics and prognosis of men and women with premature STEMI. Methods: A total 1404 consecutive patients were referred to our institution for emergency cardiac catheterization due to STEMI suspicion (1 January 2014–31 December 2018). Patients with confirmed premature (<55 years old in men and <60 in women) STEMI (366 patients, 83% men and 17% women) were included (359 atherothrombotic and 7 spontaneous coronary artery dissection (SCAD)). Results: Premature STEMI patients had a high prevalence of classical cardiovascular risk factors. Mean follow-up was 4.1 years (±1.75 SD). Mortality rates, re-hospitalization, and hospital stay showed no significant differences between sexes. More than 10% of women with premature STEMI suffered SCAD. There were no significant differences between sexes, neither among cholesterol levels nor in hypolipemiant therapy. The global survival rates were similar to that expected in the general population of the same sex and age in our region with a significantly higher excess of mortality at 6 years among men compared with the general population. Conclusion: Our results showed a high incidence of cardiovascular risk factors, a high prevalence of SCAD among young women, and a generally good prognosis after standardized treatment. During follow-up, 23% suffered a major cardiovascular event (MACE), without significant differences between sexes and observed survival at 1, 3, and 6 years of follow-up was 96.57% (95% CI 94.04–98.04), 95.64% (95% CI 92.87–97.35), and 94.5% (95% CI 91.12–97.66). An extra effort to prevent/delay STEMI should be invested focusing on smoking avoidance and optimal hypolipemiant treatment both in primary and secondary prevention.

SummaryEndothelial dysfunction plays an important role in the pathogenesis of cardiovascular diseases and diabetes mellitus. However, the causes underlying endothelial dysfunction are not fully understood. Therefore, the aim of the present study was to investigate associations of cardiovascular risk factors with soluble adhesion molecules (sE-Selectin, sICAM-1), soluble thrombomodulin (sTM) and von Willebrand factor (vWF) as markers of endothelial dysfunction. The study population consisted of a subcohort of 2,168 men and women aged 35 to 74 years randomly drawn from three cross-sectional population-based MONICA/ KORA Augsburg surveys conducted between 1984 and 1995. In multivariable linear regression analysis, current smoking, high (versus moderate) alcohol consumption, ratio of total cholesterol/HDL-cholesterol (TC/HDL-C) and C-reactive protein (CRP) were significantly associated with elevated levels of sEselectin and sICAM-1. Increased levels of sE-selectin were also found in subjects with actual hypertension, high body mass index and prevalent diabetes mellitus. In addition, low physical activity and no (versus moderate) alcohol consumption were significantly associated with elevated concentrations of sICAM-1. Levels of sTM were higher in subjects with actual hypertension, no or high amounts of alcohol intake and a high ratio of TC/ HDL-C, but were lower in subjects witha history of myocardial infarction. VWF was significantly associated with CRP only. In conclusion, sE-selectin and sICAM-1 are more strongly associated with traditional cardiovascular risk factors than sTM and vWF.

BACKGROUND Routine screening of healthy individuals for the presence of cardiovascular risk factors is important for identification of high-risk coronary artery disease (CAD) patients at early stage and to provide preventive care. Considering the high burden of CAD, such investigations are of significant importance in Indian context. METHODS In this cross-sectional study, adult individuals (18 – 68 years) were evaluated for pre-existing diseases, lipid profile, blood glucose profile, thyroid profile, haemoglobin (Hb) and vitamins D3 and B12 levels after obtaining informed consent. These variables were compared between patients stratified based on their gender and age (< 40, 40 – 60, > 60 years). RESULTS A total of 1,508 participants (mean age: 49 ± 11 years; 49.9 % females) were investigated. Hypertension, diabetes, dyslipidaemia, anaemia, vitamin D3 and B12 deficiencies, hyperthyroidism, and hypothyroidism were observed in 31.2 %, 26.5 %, 32.0 %, 8.6 %, 35.3 %, 25.1 %, 21.0 % and 0.6 % of patients respectively. Prevalence of hypertension, diabetes, and dyslipidaemia increased with ageing, while deficiencies of Hb, vitamin D3, and vitamin B12 as well as hyperthyroidism and hypothyroidism were comparable across all age groups. Males were more prone to hypertension, diabetes, and dyslipidaemia, while females were more prone to have Hb deficiency, hyperthyroidism, and hypothyroidism. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), fasting blood sugar (FBS), vitamin D3, and vitamin B12 were elevated with increase in age, while Hb levels decreased. Males exhibited higher levels of TG, low-density lipoprotein cholesterol (LDL-C), TC / HDL, LDL / HDL, FBS, and Hb, while females displayed higher levels of vitamin D3 and B12. CONCLUSIONS Our findings verify the role of age and gender on majority of cardiovascular risk factors. The high prevalence of cardiovascular risk factors is alarming and demands the need for appropriate health-care measures. KEYWORDS Age, Coronary Artery Disease, Gender, Risk Factor
