Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

The effect of ezetimibe on lipid and glucose metabolism after a fat and glucose load

AbstractObjectivesThe clinical benefit of ezetimibe, an intestinal cholesterol transporter inhibitor, for treatment of postprandial hyperlipidemia was assessed in subjects who ingested a high-fat and high-glucose test meal to mimic westernized diet.MethodsWe enrolled 20 male volunteers who had at least one of the following: waist circumference ≥ 85cm, body mass index ≥ 25kg/m2, or triglycerides (TG) from 150 to 400mg/dL. After 4 weeks of treatment with ezetimibe (10mg/day), the subjects ingested a high-fat and high-glucose meal. Then changes in serum lipid and glucose levels were monitored after 0, 2, 4, and 6h, and the area under the curve (AUC) was calculated for the change in each parameter.Results and conclusionAt 4 and 6h postprandially, TG levels were decreased (p<0.01) after 4 weeks of ezetimibe treatment, and the AUC for TG was also decreased (p<0.01). Apolipoprotein B48 (apo-B48) levels at 4 and 6h postprandially were significantly decreased after ezetimibe treatment (p<0.01 and p<0.001, respectively), and the AUC for apo-B48 was also significantly decreased (p<0.01). Blood glucose and insulin levels at 2h postprandially were significantly decreased by ezetimibe (p<0.05). The AUCs for blood glucose and insulin were also significantly decreased (p<0.05 and p<0.01, respectively). Since ezetimibe improved postprandial lipid and glucose metabolism, this drug is likely to be beneficial for dyslipidemia in patients with postprandial metabolic abnormalities

Rationale and design of the EMPYREAN study

Aims: A sodium glucose cotransporter 2 (SGLT2) inhibitor was recently found to reduce heart failure hospitalization in the EMPA‐REG OUTCOME trial. We have hypothesized that autonomic nerve activity may be modulated by SGLT2 inhibition. The current study aims to investigate the impact of empagliflozin on sympathetic and parasympathetic nerve activity in patients with type 2 diabetes mellitus. Methods and results: This ongoing study is a prospective, randomized, open‐label, multicentre investigation of 134 patients with type 2 diabetes mellitus. The patients are randomly allocated to receive either empagliflozin or sitagliptin with the treatment goal of the Japan Diabetes Society guidelines. Ambulatory electrocardiographic monitoring is performed at the baseline and at 12 and 24 weeks of treatment. Analyses of heart rate variability are conducted using the MemCalc method, which is a combination of the maximum entropy method for spectral analysis and the non‐linear least squares method for square analysis. The primary endpoint is the change in the low‐frequency (0.04–0.15 Hz)/high‐frequency (0.15–0.4 Hz) ratio from baseline to 24 weeks. Conclusions: This investigation on the effect of EMPagliflozin on cardiac sYmpathetic and parasympathetic neRve activity in JapanEse pAtieNts with type 2 diabetes (EMPYREAN study) offers an important opportunity to understand the impact of SGLT2 inhibition on autonomic nerve activity in patients with type 2 diabetes

Study design of GENERAL (general practitioners and embolism prevention in NVAF patients treated with rivaroxaban: Real-life evidence): A multicenter prospective cohort study in primary care physicians to investigate the effectiveness and safety of rivaroxaban in Japanese patients with NVAF

Background: Rivaroxaban, a direct oral anticoagulant (DOAC), has become available for stroke prevention in patients with non-valular atrial fibrillation (NVAF). However, little is known about its effectiveness and safety when prescribed by general practitioners in real-life settings. Methods: GENERAL is a multicenter, prospective, non-interventional observational study of patients receiving rivaroxaban for NVAF in daily clinical practice prescribed specifically by general practitioners. The target number of participating medical institutions is 500–700 clinics with fewer than 20 beds and the target number of participants is 5000. The baseline clinical data, including antidementia medication and frailty, and follow-up data including concomitant treatment and outcomes until September 2018 (maximum three years) will be collected. The primary efficacy endpoints will be stroke and/or systemic embolism and the secondary endpoints will be major bleeding meeting the ISTH guidelines, non-major and clinically relevant bleeding, onset of symptomatic stroke (ischemic/hemorrhagic), systemic embolism, deep vein thrombosis/pulmonary thromboembolism, myocardial infarction and/or cardiovascular death, and systemic embolism. Based on the provided information, the event assessment committee will investigate the endpoint-related events. The annual incidence and predictive factors for primary/secondary endpoint will be investigated based on underlying disease, age, renal function, and CHADS2, CHA2DS2-VASC, and HAS-BLED scores using Cox regression. We will also compare the incidence of the primary/secondary endpoint between the present study, EXPAND study, and FUSHIMI AF registry study. Results: The results of this study are currently under investigation. Conclusion: This study will provide important information regarding the effectiveness and safety of rivaroxaban treatment in Japanese patients with NVAF among general practitioners
