Abstract Background: Negatively charged very-low-density lipoprotein (VLDL-χ) in metabolic syndrome (MetS) patients exerts cytotoxic effects on endothelial cells and atrial myocytes. Atrial cardiomyopathy, manifested by atrial remodeling with a dilated diameter, contributes to atrial fibrillation pathogenesis and predicts atrial fibrillation development. The correlation of VLDL-χ with atrial remodeling is unknown. This study investigated the association between VLDL-χ and the remodeling of left atrium.Methods: Consecutively, 87 MetS and 80 non-MetS individuals between 23 and 74 years old (50.6% men) without overt cardiovascular diseases were included in the prospective cohort study. Blood samples were collected while fasting and postprandially (at 0.5, 1, 2, and 4 hours after a unified meal). VLDL was isolated by ultracentrifugation; the percentile concentration of VLDL-χ (%) was determined by ultra-performance liquid chromatography. The correlations of left atrial diameter (LAD) with variables including VLDL-χ, LDL-C, HDL-C, triglycerides, glucose, and blood pressure, were analyzed by multiple linear regression models. A hierarchicallinear model was conducted to test the independencies of each variable’s correlation with LAD.Results: The mean LAD was 3.4 ± 0.5 cm in non-MetS subjects and 3.9 ± 0.5 cm in MetS patients (P< 0.01). None of the fasting lipid profiles were associated with LAD. VLDL-χ, BMI, waist circumference, hip circumference, and blood pressure were positively correlated with LAD (all P<0.05) after adjustment for age and sex. Significant interactions between VLDL-χ and blood pressure, waist circumference, and hipcircumference were observed. When adjusted for obesity- and blood pressure-related variables, 2-hour postprandial VLDL-χ (mean 1.30 ± 0.61%) showed a positive correlation with LAD in MetS patients. Each 1% VLDL-χ increase was estimated to increase LAD by 0.23 cm.Conclusions: Postprandial VLDL-χ is associated with atrial remodeling particularly in the MetS group. VLDL-χ is a novel biomarker and may be a therapeutic target for atrial cardiomyopathy in MetS patients.Trial registration: ISRCTN 69295295. Retrospectively registered 9 June 2020.

Abstract Background and Aim Psoriasis have a direct impact on development of cardiovascular risk factors leading to atherosclerosis and metabolic abnormalities. In order to prevent the complications, early and prompt identification of factors through various parameters help in primary and secondary prevention of cardiovascular diseases (CVDs) among these psoriatic patients. Therefore the aim of this study is to determine the prevalence of various determinants for cardiovascular diseases among cases and controls. Methods A hospital based case control study at a tertiary care hospital included women from the out patient department, aged above 18 years who were known cases of psoriasis. 114 patients were recruited with 1:1 ratio between cases and controls. All patients were evaluated using semi structured interview schedule with socio demographic variables, duration of disease, family history, and usage of drugs. Severity of disease was assessed through the psoriasis area severity index (PASI). Body surface area (BSA), body mass index (BMI), waist circumference and blood pressure measurement were done using standard methods. Lipid profile, high sensitivity C-Reactive protein (HsCRP) and blood sugar through calibrated analyzers having quality control. Carotid intima media thickness (CIMT) was assessed by using carotid Doppler technique to measure atherosclerosis. Results One hundred fourteen patients, means 57 pairs of cases and controls were analyzed in this study. Significant determinants among cases were raised such as waist circumference (p = 0.025), diastolic blood pressure (p = 0.0001), low density lipoprotein (p = 0.002) and fasting blood glucose (p = 0.004) when compared to controls. HsCRP and CIMT were also raised among cases but only CIMT was statistically significant when compared to controls (p = 0.0001). We also found raised determinants among psoriatic arthritis patients compared to psoriasis. Conclusion Psoriasis patients had high waist circumference, diastolic blood pressure, low density lipoprotein, fasting blood glucose, and CIMT when compared to controls. Early identification of these determinants make them amenable for prevention.

Abstract Aldosterone is the mineralocorticoid responsible for sodium retention, thus increased blood volume and pressure. Excessive production of aldosterone results in high blood pressure as well as renal disease, stroke, and visual loss via both direct effects and effects on blood pressure. Weight gain is often associated with increased blood pressure, but it remains unclear how obesity increases blood pressure. Obese patients typically have higher lipoprotein levels; moreover, some studies have suggested that aldosterone levels are also elevated and represent a link between obesity and hypertension. Very-low-density lipoprotein (VLDL) functions to transport triglycerides from the liver to peripheral tissues. Although previous studies have demonstrated that VLDL can stimulate aldosterone production, the mechanisms underlying this effect are largely unclear. Here we show for the first time that phospholipase D (PLD) is involved in VLDL-induced aldosterone production in both a human adrenocortical cell line (HAC15) and primary cultures of bovine zona glomerulosa cells. Our data also reveal that PLD mediates steroidogenic acute regulatory (StAR) protein and aldosterone synthase (CYP11B2) expression via increasing the phosphorylation (activation) of their regulatory transcription factors. Finally, by using selective PLD inhibitors, our studies suggest that both PLD1 and PLD2 isoforms play an important role in VLDL-induced aldosterone production.

ABSTRACT: Obesity has been increasing in cats andis associated with metabolic and cardiovascular diseases. The association of these alterations can trigger the onset of metabolic syndrome (MS). Therefore, this study aimed to analyze the serum levels of glucose, fructosamine, cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, very low-density lipoprotein (VLDL), andalanine aminotransferase of cats and to identify the possibility of MS,as well as to evaluate changes in arterial pressure. Thirty-seven cats were classified by ECC and morphometric measurements, namely, 15 obese, 12 overweight, and 10 controls. Nocat manifested MS. Only VLDL had a statistically significant difference (P<0.05) between groups. Therefore, obesity may not be associated with arterial hypertension, and more studies are needed to evaluate the metabolic alterations in overweight and obese cats.

Type 2 diabetes (T2D) is now recognized as an independent risk factor for accelerated cognitive decline and neurological conditions like Alzheimer’s disease. Less is known about the neurocognitive function of T2D patients with comorbid metabolic syndrome, despite their elevated risk for impairment. Computerized testing in 47 adults with T2D that met criteria for NCEP metabolic syndrome revealed that cognitive impairment was prevalent, including 13% in tests of memory, 50% in attention, and 35% in executive function. Partial correlations showed that longer duration of diabetes was associated with poorer performance on tests of basic attention (r=-0.43), working memory (r=0.43), and executive function (r=0.42). Strong associations between very low density lipoprotein and poor cognitive function also emerged, including tests of set shifting (r=0.47) and cognitive inhibition (r=-0.51). Findings suggest that patients with T2D that meet criteria for metabolic syndrome are at high risk for cognitive impairment. Prospective studies should look to replicate these findings and examine the possible neuroprotective effects of lipid-lowering medication in this population.

Background Atherosclerosis in >1 vascular bed (ie, polyvascular disease), often a feature of peripheral artery disease (PAD), is associated with high morbidity and mortality. We sought to identify risk factors for polyvascular involvement in patients with PAD. Methods and Results We performed 2‐sample Mendelian randomization using an inverse‐variance‐weighted approach, to assess 60 exposures including size and lipid content of atherogenic lipoproteins, blood pressure, glycated hemoglobin, and smoking as causal mediators for polyvascular disease in patients with PAD. Genetic instruments for these exposures were obtained from prior genome‐wide association studies. Patients with PAD were from the Mayo Vascular Disease Biorepository, and polyvascular disease (ie, concomitant coronary heart disease, cerebrovascular disease, and/or abdominal aortic aneurysm) was ascertained by validated phenotyping algorithms. Of 3279 patients with PAD, 61% had polyvascular disease. Genetically predicted levels of the lipid content and/or particle measures of very small and small size very low‐density lipoprotein, intermediate‐density lipoprotein, and large low‐density lipoprotein were associated with polyvascular disease: odds ratios (OR) of 1.80 (95% CI, 1.23–2.61), 1.70 (95% CI, 1.17–2.61), and 1.40 (95% CI, 1.09–1.80) per 1 SD increase in genetically determined levels, respectively. Both genetically predicted diastolic and systolic blood pressure were associated with polyvascular disease; OR per 10 mm Hg genetic increase in diastolic and systolic blood pressure were 1.66 (95% CI, 1.19–2.33) and 1.31 (95% CI, 1.07–1.60), respectively. Conclusions Lifetime exposure to increased lipid content and levels of very small and small very low‐density lipoprotein, intermediate‐density lipoprotein, and large low‐density lipoprotein particles as well as elevated blood pressure are associated with polyvascular involvement in patients with PAD. Reduction in levels of such exposures may limit progression of atherosclerosis in patients with PAD.
