Carotid intima layer thickness but not intima-media thickness is related to coronary artery calcification in type 2 diabetes individuals: Results from the Brazilian diabetes study.

BACKGROUND AND AIMS: Carotid intima-media thickness (cIMT) is inconsistent in predicting cardiovascular risk. This may stem from the variability of the media thickness (cM) outweighing the intimal thickness (cIT) as the sign of atherosclerosis. Thus, we evaluated in type 2 diabetes (T2D) individuals, the association between carotid measures and coronary artery calcification (CAC). METHODS AND RESULTS: Association between the presence of CAC and cIT, cM, and cIMT were examined on 224 individuals. Logistic binary regression was used to assess CAC predictors. The Akaike information criterion (AIC) and log-likelihood test (LLT) were used to assess differences among univariate models. The cIT (0.335 mm vs 0.363 mm; p = 0.001) and cIMT (0.715 vs 0.730; p = 0.019), but not cM (0.386 mm vs 0,393 mm; p = 0.089) were higher among individuals with CAC. In unadjusted analysis, cIT (273;-134; p = 0.001) showed greater relationship with CAC, when compared to cIMT (279;-137; p = 0.022) and cM (281;-139; p = 0.112) based on the AIC and LLT, respectively. In multivariate logistic regression, CAC was related to carotid plaque (OR): 1.91, 95% confidence interval (CI):1.08, 3.38; p = 0.027), and high-cIT (OR: 2.70, 95%CI:1.51, 4.84; p = 0.001), but not to high-cIMT (OR:1.70, 95%CI:0.96, 3.00; p = 0.067) nor high-cM (OR:1.33, 95%CI:0.76, 2.34; p = 0.322). CONCLUSION: In T2D individuals, cIT is a better predictor of CAC than cIMT; cM is not associated with CAC.

Dapagliflozin cardiovascular effects on end-stage kidney disease (DARE-ESKD-2) trial: rationale and design.

Purpose: Sodium glucose co-transporter 2 inhibitors (SGLT2i) remarkably reduced the incidence of hospitalization for heart failure and cardiovascular death of conservatively managed chronic kidney disease. We hypothesized that adding SGLT2i to standard treatment would yield cardiovascular benefits also in end-stage kidney disease (ESKD) individuals on dialysis. Methods: The DARE-ESKD-2 Trial (NCT05685394) is an ongoing, single-center, open-label, controlled trial aimed at assessing the cardiovascular effects of dapagliflozin in ESKD on dialysis. Eligible patients are adults on renal replacement therapy for more than 3 prior to enrollment. Exclusion criteria encompass pregnancy, liver failure, and current use of a SGLT2i. After signing an informed consent form, participants are randomized 1:1 to either dapagliflozin 10mg PO plus standard treatment or standard treatment alone for 6 months. Echocardiogram, anthropometry, blood sample collection, 6-min walk test, gait speed, and Kansas City Cardiomyopathy Questionnaire (KCCQ), are performed at baseline and at study termination. Participants are contacted monthly during treatment for outcomes disclosure. The primary endpoint of our study is the between-groups differences in posttreatment changes in plasma levels of N-terminal pro-B natriuretic peptide. Secondary endpoints include the differences between groups in the changes of echocardiography measurements, cardiopulmonary tests performance, body composition. The incidence of safety endpoints will also be diligently compared between study arms. Conclusion: The DARE-ESKD-2 trial will provide unprecedented data on the cardiovascular safety and efficacy of SGLT2i in ESKD individuals on dialysis. This study will pave the grounds for improving clinical outcomes of dialysis recipients.

Compliance with Cardiovascular Prevention Guidelines in Type 2 Diabetes Individuals in a Middle-Income Region: A Cross-Sectional Analysis.

Stricter control of risk factors has been pursued as a compelling strategy to mitigate cardiovascular events (CVE) in type 2 diabetes (T2D) individuals. However, the achievement rate of the recommended goals has remained low in clinical practice. This study investigated the 2019 ESC guideline recommendation attainment among T2D individuals enrolled in a national cohort held in Brazil. Data from 1030 individuals (mean age: 58 years old; 54% male; mean T2D duration: 9.7 years) were analyzed. The control rates were 30.6% for SBP, 18.8% for LDL-C, and 41% for A1c, and only 3.2% of the study participants met all three targets. Statins and high-intensity lipid-lowering therapy prescription rates were 45% and 8.2%, respectively. Longer T2D duration and those at higher CV risk were less likely to be controlled. Longer diabetes duration and higher CV risk were inversely related to the chance of achieving the recommended targets. Treatment escalation using conventional therapies would be sufficient to gain optimal control in most of the study sample. In conclusion, a minimal proportion of T2D individuals comply with guidelines-oriented CV prevention targets. Given the significant burden of the disease, and the substantial effect size predicted for these therapies, bridging this gap between guidelines and clinical practice should be considered an urgent call to public health managers.
