研究目的:

在接受血管内治疗后发生出血转化的急性缺血性卒中合并房颤患者中,比较早期与延迟启动口服抗凝治疗的安全性和有效性  

Objectives of Study:

The primary objective of this trial is to evaluates the safety and efficacy of early versus delayed initiation of direct oral anticoagulants (DOACs) in patients with acute ischemic stroke related to atrial fibrillation who develop hemorrhagic transformation after endovascular treatment.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

(1)年龄≥18岁。 (2)临床诊断为急性缺血性脑卒中。 (3)此次卒中为颅内大血管急性闭塞所致,且在卒中后24小时内进行了急诊血管内治疗。 (4)已知或在住院期间诊断为阵发性、持续性或永久性房颤;通过以下任何一种检测方式进行诊断: a. 12 导联心电图(ECG)记录; b. 住院期间心电监测; c. 其他长时间心电监测技术(如 Holter 监测); d. 既往确诊房颤。 (5)急诊血管内治疗后头颅影像学检查存在以下情况: a. 出血性转化:实质性血肿面积<30%,无明显占位效应(海德堡分型PH1型)。 b. 出血性转化:实质性血肿面积>30%,并伴随明显占位效应(海德堡分型PH2型)。 c. 出血性转化:梗死区域外脑实质出血或颅内 - 颅外出血(海德堡分型3型)。 (6)此次卒中症状出现到随机分组的时间在7天~4周内。 (7)本人或法定代理人签署知情同意书。

Inclusion criteria

1. Aged 18 years or over; 2. Clinical diagnosis of large vessel occlusion acute ischemic stroke; 3. Emergency endovascular treatment was performed within 24 hours of stroke onset; 4. Atrial fibrillation (including paroxysmal, persistent or permanent atrial fibrillation), confirmed by at least one of the following: (1). 12-lead ECG recording; (2). Inpatient ECG telemetry; (3). Prolonged ECG monitoring (e.g. Holter monitor); (4). Previously established diagnosis of atrial fibrillation verified by medical records. 5. CT or MRI demonstrating one of the following findings: (1). Parenchymatous hematoma type 1: defined as hematoma occupying less than 30% of the infarcted tissue, no substantive mass effect (Heidelberg classification); (2). Parenchymatous hematoma type 2: defined as heamtoma occupying 30% or more of the infarcted tissue, with obvious mass effect (Heidelberg classification); (3). Intracerebral hemorrhage outside the infarcted brain tissue or intracranial-extracerebral hemorrhage (Heidelberg classification). 6. Time from stroke onset to randomization ranged from 7 days to 4 weeks; 7. Written informed consent obtained from the patient or a legally authorized representative.

排除标准:

(1)因可逆原因引起的房颤(如甲亢、心包炎、近期手术、心肌梗死等)。 (2)存在使用DOACs治疗的禁忌症: a. 对Xa 因子抑制剂和直接凝血酶抑制剂均过敏或不耐受; b. 明确适用于 VKA 治疗的情况,如:机械心脏瓣膜,瓣膜性房颤; c. 严重肾功能损害或肝功能异常; (严重肝功能不全的定义为ALT值>2倍正常上限或AST值>2倍正常上限;严重肾功能不全的定义为肌酐>1.5倍正常上限) d. 正在服用与 DOACs 具有显著相互作用的药物,如:唑类抗真菌药物,HIV 蛋白酶抑制剂,强 CYP3A4 诱导剂; e. 血小板减少 (< 100 × 10?/L) ; f. 凝血障碍或系统性出血病史。 (3)卒中发病48h内接受DOACs治疗,或口服华法林导致国际标准化比值(INR)>1.7。 (4)妊娠期或哺乳期女性,或入院时妊娠测试为阳性。 (5)卒中发病前1月之内接受过任何大型外科手术或有严重外伤史。 (6)卒中发病前1月之内有活动性出血史(如胃肠道出血、泌尿道出血等)。 (7)基线时使用双重抗血小板治疗,或在试验过程中有很大可能接受双重抗血小板治疗的患者。 (8)患有脑淀粉样血管病。 (9)CT或MRI显示非卒中病变,且病变可解释现有临床症状(如占位性病变、血管炎、脑炎)。 (10)发病前mRS评分>1分。 (11)无法完成90天随访的患者。 (12)当前正在参与其他药物临床试验的患者。

Exclusion criteria:

1. Atrial fibrillation due to reversible causes (e.g. thyrotoxicosis, pericarditis, recent surgery, or myocardial infarct); 2. Contraindication to the use of direct oral anticoagulants (DOACs): (1). Known allergy or intolerance to both factor Xa inhibitors and direct thrombin inhibitors; (2). Definite indication for vitamin K antagonist (VKA) treatment (e.g. mechanical heart valve, valvular atrial fibrillation); (3). Severe renal impairment (defined as creatinine exceeding 1.5 times of the upper limit of normal range) and significant hepatic dysfunction (defined as ALT or AST > twice the upper limit of normal range) ; (4). Concomitant use of medications with significant interactions with DOACs, including azole antifungals, HIV protease inhibitors, or strong CYP3A4 inducers; (5). Baseline platelet count < 100 x 10^9/L; (6). History of coagulopathy or systemic hemorrhage. 3. Prior DOAC use within 48 hours of stroke onset, or recent treatment with vitamin K antagonist (VKA) leading to INR >=1.7 at randomization; 4. Pregnant or breastfeeding women, or positive pregnancy test at admission; 5. History of major surgery or severe trauma within 1 month prior to stroke onset; 6. History of active bleeding within 1 month prior to stroke onset (e.g. gastrointestinal bleeding, urinary tract bleeding); 7. Dual antiplatelet therapy at baseline, or strong likelihood of requiring dual antiplatelet therapy during the trial; 8. Evidence of cerebral amyloid angiopathy; 9. CT or MRI evidence of non-stroke pathology likely to account for the presenting clinical symptoms (e.g. mass lesion, encephalitis); 10. Modified Rankin scale (mRS) score > 1 prior to stroke onset; 11. Inability to complete the 90-day follow-up; 12. Currently participating in another drug clinical trial; 13. Any other reason deemed by the investigator to make the patient unsuitable for participation in the trial.
