BACKGROUND AND PURPOSE
Although onset-to-treatment time is associated with early clinical recovery in acute ischemic stroke (AIS) patients treated with intravenous tissue plasminogen activator (tPA), the effect of the timing of tPA-induced recanalization on functional outcomes remains debatable.
METHODS
We conducted a multicenter, prospective observational cohort study to determine whether early (within 1-hour from tPA-bolus) complete or partial recanalization assessed during 2-hour real-time transcranial Doppler monitoring is associated with improved outcomes in patients with proximal occlusions. Outcome events included dramatic clinical recovery (DCR) within 2 and 24-hours from tPA-bolus, 3-month mortality, favorable functional outcome (FFO) and functional independence (FI) defined as modified Rankin Scale (mRS) scores of 0-1 and 0-2 respectively.
RESULTS
We enrolled 480 AIS patients (mean age 66±15 years, 60% men, baseline National Institutes of Health Stroke Scale score 15). Patients with early recanalization (53%) had significantly (P<0.001) higher rates of DCR at 2-hour (54% vs. 10%) and 24-hour (63% vs. 22%), 3-month FFO (67% vs. 28%) and FI (81% vs. 39%). Three-month mortality rates (6% vs. 17%) and distribution of 3-month mRS scores were significantly lower in the early recanalization group. After adjusting for potential confounders, early recanalization was independently associated with higher odds of 3-month FFO (odds ratio [OR], 6.19; 95% confidence interval [CI], 3.88 to 9.88) and lower likelihood of 3-month mortality (OR, 0.34; 95% CI, 0.17 to 0.67). Onset to treatment time correlated to the elapsed time between tPA-bolus and recanalization (unstandardized linear regression coefficient, 0.13; 95% CI, 0.06 to 0.19).
CONCLUSIONS
Earlier tPA treatment after stroke onset is associated with faster tPA-induced recanalization. Earlier onset-to-recanalization time.
RESULTS
in improved functional recovery and survival in AIS patients with proximal intracranial occlusions.
背景与目的
尽管在接受静脉注射组织型纤溶酶原激活剂（tPA）治疗的急性缺血性卒中（AIS）患者中，从发病到治疗的时间与早期临床恢复相关，但tPA诱导再通的时机对功能结局的影响仍存在争议。
方法
我们进行了一项多中心、前瞻性观察队列研究，以确定在2小时实时经颅多普勒监测期间评估的早期（tPA推注后1小时内）完全或部分再通是否与近端闭塞患者的预后改善相关。结局事件包括tPA推注后2小时和24小时内的显著临床恢复（DCR）、3个月死亡率、良好功能结局（FFO）和功能独立性（FI），分别定义为改良Rankin量表（mRS）评分为0 - 1和0 - 2。
结果
我们纳入了480例AIS患者（平均年龄66±15岁，60%为男性，基线美国国立卫生研究院卒中量表评分为15）。早期再通的患者（53%）在2小时（54%对10%）和24小时（63%对22%）时的DCR率、3个月FFO（67%对28%）和FI（81%对39%）显著更高（P<0.001）。早期再通组的3个月死亡率（6%对17%）和3个月mRS评分分布显著更低。在调整潜在混杂因素后，早期再通与3个月FFO的较高几率（优势比[OR]，6.9；95%置信区间[CI]，3.88至9.88）和3个月死亡率的较低可能性（OR，0.34；95%CI，0.17至0.67）独立相关。从发病到治疗的时间与tPA推注到再通的时间间隔相关（非标准化线性回归系数，0.13；95%CI，0.06至0.19）。
结论
卒中发作后更早的tPA治疗与tPA诱导的更快再通相关。更早的从发病到再通时间。
结果
在有近端颅内闭塞的AIS患者中改善了功能恢复和生存率。
