N2 - Background: Several prospective studies have identified that hypertension is an important risk factor of post-stroke depression (PSD). However, the effect of immediate antihypertensive treatment on the risk of PSD in patients with acute ischemic stroke remains unknown. Methods: In this prespecified depression substudy of the China Antihypertensive Trial in Acute Ischemic Stroke (CATIS) randomized clinical trial, a total of 642 patients with acute ischemic stroke within 48 h of onset and elevated systolic BP at 7 sites of CATIS were included. Patients were randomly assigned to receive antihypertensive treatment (n = 318) or to control group (n = 324). The primary outcome was depression (Hamilton Rating Scale for Depression score≥8) at 3-month posttreatment follow-up. Results: At 24 h after randomization, the mean systolic BP was reduced by 21.6 mm Hg (12.5%) in the treatment group and 13.9 mm Hg (7.9%) in the control group (difference, -7.7 mm Hg [95% CI, -10.2 to -5.2]; P<0.001). The mean systolic BP levels at 7 days (P<0.001) and 14 days (P<0.001) after randomization in treatment group were also significantly lower than those in control group. At 3-month posttreatment follow-up, 122 patients (38.4%) in antihypertensive treatment group and 131 patients (40.4%) in control group developed PSD (odds ratio, 0.92 [95% CI, 0.67 to 1.26]; P = 0.59). Limitations: All patients in the CATIS trial were Chinese, which might limit the generalizability of our findings to other populations. Conclusions: Early antihypertensive treatment had no effect on the risk of PSD at 3 months among patients with acute ischemic stroke and elevated BP.
