ABSTRACT
BACKGROUND AND PURPOSE:
As outcomes for acute ischemic stroke (AIS) vary according to clinical profile and management approaches, we aimed to determine disparities in clinical outcomes between Asian and non-Asian participants of the international, Enhanced Control of Hypertension and Thrombolysis Stroke study (ENCHANTED).METHODS:
ENCHANTED was a multicenter, prospective, partial-factorial, randomized, open trial of low-dose (0.6 mg/kg) versus standard-dose (0.9 mg/kg) alteplase, and intensive (target systolic blood pressure [SBP] 130-140 mm Hg) or guideline-recommended (<180 mm Hg) BP management, in thrombolysis-eligible AIS patients. Logistic regression models were used to examine the associations with outcomes of death or disability (modified Rankin scale [mRS] scores 2-6), major disability (mRS 3-5), death, and intracranial hemorrhage (ICH), with adjustment prognostic factors, alteplase dose, and mean SBP over 1-24 h.RESULTS:
Among 4,551 thrombolyzed AIS patients (mean age 66.7 years, 37.8% female), there were 65.4% Asians who were younger, fewer female, and with less atrial fibrillation, hypercholesterolemia, premorbid symptoms, and concomitant antihypertensive, antithrombotic and statin treatment, and more prior stroke, compared to non-Asians. Frequencies of hypertension, coronary artery disease, and diabetes mellitus were comparable between groups. Asian patients were less likely to be admitted to an acute stroke unit and receive early mobilization by a therapist or rehabilitation but more likely to receive intensive care. There were no significant differences between Asians and non-Asians in functional outcome (defined by mRS scores 2-6 or 3-5; adjusted odds ratio [OR] 1.00, 95% confidence interval [CI] 0.85-1.19 [p = 0.958] and OR 0.95, 95% CI 0.80-1.13 [p = 0.572], respectively), or death (OR 1.25, 95% CI 0.95-1.65; p = 0.116), despite Asians having greater odds of ICH (OR 1.51, 95% CI 1.23-1.86; p = 0.0001) and neurological deterioration within 24 h (OR 1.58, 95% CI 1.18-2.12; p = 0.002).CONCLUSIONS:
Within the context of an international clinical trial of thrombolyzed AIS patients, demography, risk factors, management, and odds of early neurological deterioration and ICH, all differ between Asian and non-Asian participants. However, patterns of functional recovery are similar between these major regional groups.Palabras clave
