TCEP was safe, captured embolic debris in 99% of patients, and did not change neurocognitive function. Reduction in new lesion volume on magnetic resonance scans was not statistically significant. (Cerebral Protection in Transcatheter Aortic Valve Replacement [SENTINEL]; NCT02214277).

Summary. Background: Little information is available on the epidemiology of venous thromboembolism (VTE) in Asian populations. Objectives: To investigate VTE incidence, VTE cumulative recurrence rates and risk factors for VTE recurrence among the adult Taiwanese population. Methods: This population-based cohort study used the Taiwanese National Health Insurance claims databases to identify 5347 adult patients (2463 men, 46.1%) with VTE diagnosed in 2001 and 2002. We calculated the crude incidence of VTE and its recurrence. We also conducted a nested case-control study (n = 3576) among this population to estimate the association between VTE recurrence and exposure to potential VTE risk factors by conditional logistic regression. Results: The crude incidence of VTE was 15.9 per 100 000 person-years, and its recurrence rate was 5.1% per person-year. During 11 566 person-years of follow-up, the cumulative rates of VTE recurrence at 6, 12, 24, 36 and 47 months were 6.7%, 9.4%, 12.4%, 13.9%, and 14.4%, respectively. By conditional logistic regression, histories of VTE [adjusted odds ratio (OR) 1.71, 95% confidence interval (CI) 1.32-2.16] or malignant neoplasm (adjusted OR 1.64, 95% CI 1.26-1.99), major extremity trauma (adjusted OR 2.76, 95% CI 1.82-4.52), serious neurologic diseases (adjusted OR 1.43, 95% CI 1.12-1.84) or undergoing major surgery (adjusted OR 4.57, were associated with higher risks of VTE recurrence. Conclusions: The incidence of VTE is lower in the Taiwanese population than in Caucasians. Most VTE recurrences occur within 12 months, but they continue to occur beyond 1 year. The VTE recurrences are associated with malignancy, history of VTE, and major surgery after a previous VTE.

Atrial fibrillation (AF) is the most common sustained arrhythmia. Both the incidence and prevalence of AF are increasing, and the burden of AF is becoming huge. Many innovative advances have emerged in the past decade for the diagnosis and management of AF, including a new scoring system for the prediction of stroke and bleeding events, the introduction of non-vitamin K antagonist oral anticoagulants and their special benefits in Asians, new rhythm- and rate-control concepts, optimal endpoints of rate control, upstream therapy, life-style modification to prevent AF recurrence, and new ablation techniques. The Taiwan Heart Rhythm Society and the Taiwan Society of Cardiology aimed to update the information and have appointed a jointed writing committee for new AF guidelines. The writing committee members comprehensively reviewed and summarized the literature, and completed the 2016 Guidelines of the Taiwan Heart Rhythm Society and the Taiwan Society of Cardiology for the Management of Atrial Fibrillation. This guideline presents the details of the updated recommendations, along with their background and rationale, focusing on data unique for Asians. The guidelines are not mandatory, and members of the writing committee fully realize that treatment of AF should be individualized. The physician's decision remains most important in AF management.

Background-By inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase, statins not only reduce cholesterol biosynthesis but also decrease the formation of isoprenoids, which are important for mediating signaling through the Rho-associated coiled-coil containing protein kinase (ROCK) pathway. Increased ROCK activity has been implicated in endothelial dysfunction and vascular inflammation. We hypothesize that ezetimibe, which inhibits intestinal cholesterol absorption, may not exert similar cholesterol-independent or pleiotropic effects of statins and, when used with a lower dose of statin, have less effect on ROCK activity than a higher dose of statin. Methods and Results-In a prospective, randomized, observer-blinded study, we treated 60 dyslipidemic subjects without cardiovascular disease with simvastatin 40 mg/d, simvastatin/ezetimibe 10/10 mg/d, or placebo tablets for 28 days (nϭ20 in each arm). We evaluated baseline demographics and lipid levels, ROCK activity, C-reactive protein, and flow-mediated dilation before and after treatment. Compared with the placebo group, both treatment regimens decreased low-density lipoprotein cholesterol by 38% and C-reactive protein by 38% to 40% after 28 days (PϽ0.01 for both compared with placebo). Although the low-density lipoprotein cholesterol and C-reactive protein reductions were comparable with either lipid-lowering regimen, only simvastatin 40 mg reduced ROCK activity and improved flow-mediated dilation (PϽ0.01 for both compared with baseline). Reduction in ROCK activity with simvastatin 40 mg remained significant even after controlling for changes in low-density lipoprotein cholesterol (Pϭ0.01) and correlated with improvement in flow-mediated dilation (R 2 ϭϪ0.78, PϽ0.01). No correlation was found between changes in flow-mediated dilation and changes in low-density lipoprotein cholesterol or C-reactive protein. Conclusion-These

Rho kinase activity is increased in Taiwanese subjects with MetS and is associated with each component of MetS and markers of inflammation. These findings suggest that ROCK activity may be a novel serological marker of MetS.
