Thrombolysis outcomes in acute ischemic stroke patients with prior stroke and diabetes mellitus
No full textBackground: Patients with concomitant diabetes mellitus (DM) and prior stroke (PS) were excluded from European approval of alteplase in stroke. We examined the influence of DM and PS on the outcomes of patients who received thrombolytic therapy (T; data from Safe Implementation of Thrombolysis in Stroke-International Stroke Thrombolysis Register) compared to nonthrombolyzed controls (C; data from Virtual International Stroke Trials Archive). Methods: We selected ischemic stroke patients on whom we held data on age, baseline NIH Stroke Scale score (NIHSS), and 90-day modified Rankin Scale score (mRS). We compared the distribution of mRS between T and C by Cochran-Mantel-Haenszel (CMH) test and proportional odds logistic regression, after adjustment for age and baseline NIHSS, in patients with and without DM, PS, or the combination. We report odds ratios (OR) for improved distribution of mRS with 95% confidence interval (CI) and CMH p value. Results: Data were available for 29,500 patients: 5,411 (18.5%) had DM, 5,019 had PS (17.1%), and 1,141 (5.5%) had both. Adjusted mRS outcomes were better for T vs C among patients with DM (OR 1.45 [1.30-1.62], n = 5,354), PS (OR 1.55 [1.40-1.72], n = 4,986), or concomitant DM and PS (OR 1.23 [0.996-1.52], p = 0.05, n = 1,136), all CMH p 80 years did not influence our findings. Conclusions: Outcomes from thrombolysis are better than the controls among patients with DM, PS, or both. We find no statistical justification for the exclusion of these patients from receiving thrombolytic therapy. Neurology (R) 2011; 77: 1866-187
Rapid blood-pressure lowering in patients with acute intracerebral hemorrhage.
No full textWhether rapid lowering of elevated blood pressure would improve the outcome in patients with intracerebral hemorrhage is not known. We randomly assigned 2839 patients who had had a spontaneous intracerebral hemorrhage within the previous 6 hours and who had elevated systolic blood pressure to receive intensive treatment to lower their blood pressure (with a target systolic level of <140 mm Hg within 1 hour) or guideline-recommended treatment (with a target systolic level of <180 mm Hg) with the use of agents of the physician's choosing. The primary outcome was death or major disability, which was defined as a score of 3 to 6 on the modified Rankin scale (in which a score of 0 indicates no symptoms, a score of 5 indicates severe disability, and a score of 6 indicates death) at 90 days. A prespecified ordinal analysis of the modified Rankin score was also performed. The rate of serious adverse events was compared between the two groups. Among the 2794 participants for whom the primary outcome could be determined, 719 of 1382 participants (52.0%) receiving intensive treatment, as compared with 785 of 1412 (55.6%) receiving guideline-recommended treatment, had a primary outcome event (odds ratio with intensive treatment, 0.87; 95% confidence interval [CI], 0.75 to 1.01; P=0.06). The ordinal analysis showed significantly lower modified Rankin scores with intensive treatment (odds ratio for greater disability, 0.87; 95% CI, 0.77 to 1.00; P=0.04). Mortality was 11.9% in the group receiving intensive treatment and 12.0% in the group receiving guideline-recommended treatment. Nonfatal serious adverse events occurred in 23.3% and 23.6% of the patients in the two groups, respectively. In patients with intracerebral hemorrhage, intensive lowering of blood pressure did not result in a significant reduction in the rate of the primary outcome of death or severe disability. An ordinal analysis of modified Rankin scores indicated improved functional outcomes with intensive lowering of blood pressure.
