All four DOACs - apixaban, dabigatran, edoxaban, and rivaroxaban - were shown to reduce the risk of major bleeding compared to warfarin. The predictable pharmacokinetic profiles of DOACs also favour their use over warfarin. Together with increasing AF incidence due to population ageing, increased AF detection, and territory-wide reimbursement schemes, DOAC prescriptions have been surging worldwide. In Hong Kong, more than 78,354 patients received DOAC from January 2009 through April 2021 according to the Hospital Authority registry.\n\nThe more liberal use of DOACs has led to new issues that require a thorough understanding of ethnic-specific DOAC pharmacokinetic profiles. For instance, 12- 15% of anticoagulated patients annually required interventional procedures that involve temporary discontinuation of DOAC for 48 hours or more. Although guideline-based periprocedural DOAC interruption resulted in a low 30-day thromboembolism rate of 0.16% - 0.6% in a Caucasian cohort, same measures for elective colonoscopies in a local population-based study resulted in a 30-day periprocedural thromboembolism rate of up to 2.2%. Although these studies cannot be compared directly, the remarkable interethnic discrepancy between the two cohorts warrants further pharmacokinetic and pharmacogenomic studies. More importantly, quantifying residual DOAC levels during the interruption periods may imply on duration of periprocedural DOAC interruption, length of hospital-stay, and the risk of thromboembolic and bleeding complications.\n\nMapping inter- and intra-individual variations in DOAC levels may also impact on the management of ischemic stroke among DOAC recipients. Epidemiological studies have shown alarmingly up to 13% of acute ischemic stroke patients were on anticoagulation prior to stroke onset with increasing number of DOAC. These patients received low rates of recanalization therapy due to apprehension of bleeding complications, thus compromised survival and neurological recovery. A prospective study that reveals Asian-specific DOAC pharmacokinetic profiles may inform cross-disciplinary, territory-wide periprocedural care and acute stroke intervention strategy for the rapidly expanding DOAC population.",[26,27,28,29,30,31,32],"Atrial Fibrillation","Stroke","Stroke, Acute","Brain Diseases","Major Adverse Cardiovascular Event","Arterial Thromboembolism","Venous Thromboembolism","RECRUITING","2026-07-28",{"date":36,"type":37},"2026-07-30","ACTUAL",{"date":39,"type":37},"2022-09-28",{"date":41,"type":22},"2027-12-31",{"name":43,"class":44},"Chinese University of Hong Kong","OTHER",1,{"id":47,"slug":48,"hasResults":11,"nctId":49,"briefTitle":50,"officialTitle":51,"acronym":4,"eligibilityCriteria":52,"healthyVolunteers":11,"sex":17,"minAge":18,"maxAge":4,"enrollmentInfo":53,"targetDuration":4,"studyType":23,"phases":4,"briefSummary":55,"conditions":56,"keywords":4,"overallStatus":33,"whyStopped":4,"lastUpdateSubmitDate":59,"lastUpdatePostDateStruct":60,"startDateStruct":62,"completionDateStruct":64,"leadSponsor":66,"locationsCount":67},"100483689","effective-translation-of-endovascular-thrombectomy-trials-into-real-world-practice-in-the-asia-pacific-100483689","NCT05578300","Effective Translation of Endovascular Thrombectomy Trials Into Real-world Practice in the Asia-Pacific","Effective Translation of Endovascular Thrombectomy Trials Into Real-world Practice in the Asia-Pacific: a Multicenter, Prospective Registry (ENDURE-APAC)","Inclusion Criteria:\n\n* Patient who are over 18 years of age.\n* Patient with ischemic stroke with suspected large vessel occlusion (LVO), defined as occlusion of the internal carotid artery (ICA), M1 or M2 segment of the middle cerebral artery (MCA), or basilar artery (BA).\n\nExclusion Criteria:\n\n* Patient with isolated vertebral artery occlusion not involving the BA.",{"count":54,"type":22},350,"As a major breakthrough of acute stroke treatment over the past decade, endovascular thrombectomy (EVT) drastically improved neurological recovery and survival in patients with large vessel occlusion (LVO) ischemic strokes in major clinical trials.

For instance, healthcare policies that influence critical time-matrices, endovascular thrombectomy techniques that may enhance success rate or prevent complications, or advanced imaging techniques that allow precise prognosis or expansion of treatment populations, should be evaluated.
