Abstract
BACKGROUND AND OBJECTIVE The hypertriglyceridaemic waist (HTW) phenotype is defined for the general population. Chronic kidney disease (CKD) tends to bring on changes in body composition, is associated with higher comorbidity than the general population and, furthermore, shows reverse epidemiology with related prognostic variables like cholesterol and body mass index. Our objective was to identify cut-off points in the population with CKD and to analyse its relationship with cardiovascular risk (CVR). METHODS We included 2271 CKD patients from the NEFRONA cohort. Triglyceride and waist cut-off points were selected through quintiles analysis and receiver operating characteristic (ROC) curves evaluation, using the presence of moderate to severe atherosclerosis score (AS 2-3) as outcome variable. Then, we analysed HTW prevalence and its association with other cardiovascular risk factors, and we measured the magnitude of its effect on AS 2-3 and cardiovascular event or death (CVEoD) by multivariate regression analysis. RESULTS We selected the cut-off points: triglyceride concentrations ≥143 mg/dl with waist circumference values>102cm in men and 94cm in women (sensitivity 26%; specificity 87%). Specific HTW prevalence was 22.4%, without significative differences between CKD stages. The multivariate regression analysis shows specific HTW as an independent AS 2-3 (OR 1.61; 95% CI: 1.12-2.32, p=0.011) and CVEoD (HR 3.08; 95% CI: 1.66-5.72, p=0.000) risk factor. An interaction between phosphorus level and specific HTW was identified. CONCLUSIONS Adapting the HTW definition might improve specificity to assess cardiovascular risk in the population with CKD. It identifies an additional CVR in a population in which other screening methods have not proven to be useful, and it is easily clinically accessible. Its interaction with phosphorus levels suggests an association between HTW and bone-mineral metabolism regulation.

Abstract
BACKGROUND Individuals with diabetes have remarkably high rates of cardiovascular morbidity and mortality. However, the incremental cardiovascular risk in diabetes is heterogeneous and has often been related to renal involvement. The purpose of this study was to analyse the prognostic value of subclinical atherosclerosis in determining the incidence of first cardiovascular events (CVEs) in individuals with diabetes and chronic kidney disease (CKD) compared to CKD individuals without diabetes. METHODS We included data from individuals with CKD with and without diabetes, free from pre-existing cardiovascular disease, from the NEFRONA cohort. Participants underwent baseline carotid and femoral ultrasound and were followed up for 4 years. All CVEs during follow-up were registered. Bivariate analysis and Fine-Gray competing risk models were used to perform the statistical analysis. RESULTS During the mean follow-up time of 48 months, a total of 203 CVE was registered. 107 CVE occurred among participants without diabetes (19.58 per 1000 person-years) and 96 CVE occurred among participants with diabetes (44.44 per 1000 person-years). Following the competing risk analysis, the variables predicting CVEs in CKD individuals without diabetes were the number of territories with plaque at baseline (HR 1.862, 95% CI [1.432;2.240]), age (HR 1.026, 95% CI [1.003;1.049]) and serum concentrations of 25-OH vitamin D (HR 0.963, 95% CI [0.933;0.094]). The only variable predicting CVEs among CKD participants with diabetes was the number of territories with plaque at baseline (HR 1.782, 95% CI [1.393, 2.278]). For both models, concordance (C) index yielded was over 0.7. CONCLUSIONS The burden of subclinical atherosclerosis is the strongest predictor of future CVEs in diabetic individuals with CKD. Early detection of subclinical atherosclerotic burden by multiterritorial vascular ultrasound could improve CVE prediction in this population.

Abstract
BACKGROUND Prediabetes has recently been associated with subclinical atheromatous disease in the middle-aged population. Our aim was to characterize atheromatous plaque burden by the number of affected territories and the total plaque area in the prediabetes stage. METHODS Atheromatous plaque burden (quantity of plaques and total plaque area) was assessed in 12 territories from the carotid and femoral regions using ultrasonography in 6688 non-diabetic middle-aged subjects without cardiovascular disease. Prediabetes was defined by glycosylated hemoglobin (HbA1c) between 5.7 and 6.4% according to the American Diabetes Association guidelines. RESULTS Prediabetes was diagnosed in 33.9% (n = 2269) of the ILERVAS participants. Subjects with prediabetes presented a higher prevalence of subclinical atheromatous disease than participants with HbA1c < 5.7% (70.4 vs. 67.5%, p = 0.017). In the population with prediabetes this was observed at the level of the carotid territory (p < 0.001), but not in the femoral arteries. Participants in the prediabetes stage also presented a significantly higher number of affected territories (2 [1;3] vs. 1 [0;3], p = 0.002), with a positive correlation between HbA1c levels and the number of affected territories (r = 0.068, p < 0.001). However, atheromatosis was only significantly (p = 0.016) magnified by prediabetes in those subjects with 3 or more cardiovascular risk factors. The multivariable logistic regression model showed that the well-established cardiovascular risk factors together with HbA1c were independently associated with the presence of atheromatous disease in participants with prediabetes. When males and females were analyzed separately, we found that only men with prediabetes presented both carotid and femoral atherosclerosis, as well as an increase of total plaque area in comparison with non-prediabetic subjects. CONCLUSIONS The prediabetes stage is accompanied by an increased subclinical atheromatous disease only in the presence of other cardiovascular risk factors. Prediabetes modulates the atherogenic effect of cardiovascular risk factors in terms of distribution and total plaque area in a sex-dependent manner. Trial registration NCT03228459 (clinicaltrials.gov).

Abstract
BACKGROUND AND OBJECTIVES Ultrasonographic detection of subclinical atheromatosis is a noninvasive method predicting cardiovascular events. Risk factors predicting atheromatosis progression in CKD are unknown. Predictors of atheromatosis progression were evaluated in patients with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Our multicenter, prospective, observational study included 1553 patients with CKD (2009-2011). Carotid and femoral ultrasounds were performed at baseline and after 24 months. A subgroup of 476 patients with CKD was also randomized to undergo ultrasound examination at 12 months. Progression of atheromatosis was defined as an increase in the number of plaque territories analyzed by multivariate logistic regression. RESULTS Prevalence of atheromatosis was 68.7% and progressed in 59.8% of patients after 24 months. CKD progression was associated with atheromatosis progression, suggesting a close association between pathologies. Variables significantly predicting atheromatosis progression, independent from CKD stages, were diabetes and two interactions of age with ferritin and plaque at baseline. Given that multiple interactions were found between CKD stage and age, phosphate, smoking, dyslipidemia, body mass index, systolic BP (SBP), carotid intima-media thickness, plaque at baseline, uric acid, cholesterol, 25-hydroxy vitamin D (25OH vitamin D), and antiplatelet and phosphate binders use, the analysis was stratified by CKD stages. In stage 3, two interactions (age with phosphate and plaque at baseline) were found, and smoking, diabetes, SBP, low levels of 25OH vitamin D, and no treatment with phosphate binders were positively associated with atheromatosis progression. In stages 4 and 5, three interactions (age with ferritin and plaque and plaque with smoking) were found, and SBP was positively associated with atheromatosis progression. In dialysis, an interaction between body mass index and 25OH vitamin D was found, and age, dyslipidemia, carotid intima-media thickness, low cholesterol, ferritin, and uric acid were positively associated with atheromatosis progression. CONCLUSIONS Atheromatosis progression affects more than one half of patients with CKD, and predictive factors differ depending on CKD stage.

Abstract
BACKGROUND Small vessel disease (SMD) remains a major challenge because of the increased risk of restenosis. We sought to assess the efficacy and safety of a paclitaxel-eluting balloon (PEB) in patients with SMD. METHODS AND RESULTS One-hundred and four patients with native coronary lesions in small vessels treated by using a PEB were included in this prospective multicenter registry. In each case, after regular balloon dilatation, a larger PEB was inflated for a minimum of 45-60 seconds. Patients were 65 ± 10 years old, 43% diabetic, and 58% presented acutely. Angiographic success was 93% (7% bailout BMS implantation due to coronary dissection). The rate of major adverse cardiac events (MACE) at 12 months was 4.8% (1.9% cardiac death, 1.0% MI, and 2.9% TLR). One definite stent thrombosis was reported at 6 months in a patient with bailout BMS implantation. At 7 months, late loss was 0.31 ± 0.2 mm. Bail-out BMS after DEB use, was an independent predictor of MACE, HR 18.74, 95%CI (2.58-135.84) and TLR, HR 30.99, 95%CI (2.79-344.07). CONCLUSION The use of this PEB for the treatment of SMD provides excellent 1-year outcomes with only 4.8% MACE. The need for a bailout BMS was a strong predictor of MACE and TLR.
