OPTIMAL-DIABETES trial design details intensive versus standard blood pressure control in type 2 diabetes.

This paper outlines the rationale, design, and baseline characteristics of the OPTIMAL-DIABETES trial, which will evaluate intensive (<120 mm Hg) versus standard (<140 mm Hg) systolic blood pressure targets in an ethnically diverse Brazilian cohort of 9,476 patients with type 2 diabetes and high cardiovascular risk.

Despite guideline-recommended therapy, patients with noncardioembolic ischemic stroke remain at substantial risk of recurrence, with approximately 1 in 10 experiencing another stroke within 1 year. In this context, we observed a significant 26% relative reduction in the hazard of ischemic stroke with asundexian. This corresponded to an absolute risk reduction of 1.9% and a number needed to treat of 54 at 1 year. This represents a meaningful incremental benefit on top of contemporary secondary stroke prevention strategies.

In patients with aneurysmal subarachnoid hemorrhage, delayed cerebral ischemia-related infarction accounts for an estimated 12.1% of in-hospital mortality but mediates only 7.3% of the effect of poor initial neurological grade on 3- to 6-month unfavorable functional outcomes.

Functional prognosis according to therapeutic window in patients with acute ischemic stroke treated with IV thrombolysis in Latin American hospitals

AIM: To describe outcomes among treated patients with thrombolysis and compare associations across three therapeutic-window periods in acute ischemic stroke. METHODS: We conducted a subanalysis of the FAICAM registry, a retrospective multicenter cohort from 2022, including patients ≥18 years with acute ischemic stroke treated with intravenous alteplase within or beyond the standard therapeutic window. Patients with baseline Modified Rankin Scale (mRS) of >2 or those who underwent thrombectomy were excluded. Bivariate and multivariate analyses were performed for therapeutic windows of ≤3, 3-4.5, and >4.5 hours RESULTS: We analyzed 355 patients; 283 of whom had 3-month mRS data. Functional independence was 82.0% in group treated within first 3 hours, 68.9% (between 3 and 4.5 hours), and 58.6% (after 4.5 hours) at 3 months. In the multivariate analysis, patients treated between 3 and 4.5 (aRR: 0.83; 95% CI: 0.72-0.96; p = 0.011) and >4.5 hours (aRR: 0.71; 95% CI: 0.56-0.90; p = 0.005) were associated with a lower probability of functional independence versus ≤3 hours.at 3 months CONCLUSIONS: In this real-world cohort of patients treated with intravenous alteplase in Latin American hospitals, treatment closer to symptom onset was associated with a higher probability of functional independence at 3 months; because this study did not include an untreated comparison group, it cannot establish the efficacy of thrombolysis itself. These findings underscore the importance of standardizing selection criteria and hospital protocols to improve safety monitoring for patients treated within the extended window.
