- BACKGROUND AND AIMS: Patients with long atrial high-rate episodes (AHRE) ≥ 24 hours and stroke risk factors are often treated with anticoagulation for stroke prevention. Anticoagulation has never been compared to no anticoagulation in these patients.METHODS: This secondary prespecified analysis of NOAH-AFNET 6 examined interactions between AHRE duration at baseline and anticoagulation with edoxaban compared to placebo in patients with AHRE and stroke risk factors. The primary efficacy outcome was a composite of stroke, systemic embolism, or cardiovascular death. The safety outcome was a composite of major bleeding and death. Key secondary outcomes were components of these outcomes and ECG-diagnosed atrial fibrillation.RESULTS: AHRE ≥24 hours were present at baseline in 259/2389 patients enrolled in NOAH-AFNET 6 (11%, 78 ± 7 years old, 28% women, CHA2DS2-VASc score 4). Clinical characteristics were not different from patients with shorter AHRE. During a median follow-up of 1.8 years, the primary outcome occurred in 9/132 patients with AHRE ≥24 hours (4.3%/patient-year, 2 strokes) treated with anticoagulation and in 14/127 patients treated with placebo (6.9%/patient-year, 2 strokes). AHRE duration did not interact with the efficacy (p-interaction = 0.65) or safety (p-interaction = 0.98) of anticoagulation. Analyses including AHRE as a continuous parameter confirmed this. Patients with AHRE ≥24 hours developed more ECG-diagnosed atrial fibrillation (17.0%/patient-year) than patients with shorter AHRE (8.2%/patient-year; p < 0.001).CONCLUSIONS: This hypothesis-generating analysis does not find an interaction between AHRE duration and anticoagulation therapy in patients with device-detected AHRE and stroke risk factors. Further research is needed to identify patients with long AHRE at high stroke risk.

- Aim: Five multicentre, cross-sectional Centralized Pan-Regional Surveys on the Undertreatment of Hypercholesterolaemia (CEPHEUS) were conducted in 29 countries across Asia, Western Europe, Eastern Europe, the Middle East, and Africa. The surveys assessed the current use and efficacy of lipid-lowering drugs (LLDs) worldwide and identified possible patient and physician characteristics associated with failure to attain low-density lipoprotein cholesterol (LDL-C) goals. The aim of this analysis was to consolidate the global results from these surveys. Methods: The surveys involved patients aged >= 18 years who had been prescribed LLDs for at least 3 months without dose changes for at least 6 weeks. A single visit was scheduled for data collection, including fasting plasma lipid and glucose levels. Cardiovascular risk profile and LDL-C goal attainment were assessed according to the 2004 updated US National Cholesterol Education Program Adult Treatment Panel III guidelines. Results: In total, 35 121 patients (mean age: 60.4 years) were included, and 90.3% had been prescribed statin monotherapy. Overall, only 49.4% of patients reached their recommended LDL-C level. LDL-C goals were attained in 54.8% (5084/9273) and 22.8% (3287/14 429) of patients were at high and very high cardiovascular risk, respectively. Factors associated with an increased likelihood of LDL-C goal attainment were lower baseline cardiovascular risk; presence of diabetes mellitus, hypertension, or history of cardiovascular disease; and treatment with simvastatin, atorvastatin, or rosuvastatin (vs. all other LLDs). Conclusion: LDL-C goal attainment in patients taking LLDs is suboptimal worldwide, particularly in patients at high and very high cardiovascular risk.

- Background Prolyl carboxypeptidase (PRCP) is involved in the regulation of body weight, likely by hydrolysing alpha-melanocyte-stimulating hormone and apelin in the hypothalamus and in the periphery. A link between PRCP protein concentrations in plasma and metabolic disorders has been reported. In this study, we investigated the distribution of circulating PRCP activity and assessed its relation with body weight and adipose tissue in obese patients and patients who significantly lost weight. Methods PRCP activity was measured using reversed-phase high-performance liquid chromatography in different isolated blood fractions and primary human cells to investigate the distribution of circulating PRCP. PRCP activity was measured in serum of individuals (n = 75) categorized based on their body mass index (BMI < 25.0; 25.0-29.9; 30.0-39.9; >= 40.0 kg/m(2)) and the diagnosis of metabolic syndrome. Differences in serum PRCP activity were determined before and six months after weight loss, either by diet (n = 45) or by bariatric surgery (n = 24). Potential correlations between serum PRCP activity and several metabolic and biochemical parameters were assessed. Additionally, plasma PRCP concentrations were quantified using a sensitive ELISA in the bariatric surgery group. Results White blood cells and plasma contributed the most to circulating PRCP activity. Serum PRCP activity in lean subjects was 0.83 +/- 0.04 U/L and increased significantly with a rising BMI (p<0.001) and decreased upon weight loss (diet, p<0.05; bariatric surgery, p<0.001). The serum PRCP activity alteration reflected body weight changes and was found to be positively correlated with several metabolic parameters, including: total, abdominal and visceral adipose tissue. Plasma PRCP concentration was found to be significantly correlated to serum PRCP activity (0.865; p<0.001). Additionally, a significant decrease (p<0.001) in plasma PRCP protein concentration (mean +/- SD) before (18.2 +/- 3.7 ng/mL) and 6 months after bariatric surgery (15.7 +/- 2.7 ng/mL) was found. Conclusion Our novel findings demonstrate that white blood cells and plasma contributed the most to circulating PRCP activity. Additionally, we have shown that there were significant correlations between serum PRCP activity and various metabolic parameters, and that plasma PRCP concentration was significantly correlated to serum PRCP activity. These novel findings on PRCP activity in serum support further investigation of its in vivo role and involvement in several metabolic diseases.
