Randomized Controlled Trial Comparative Study
Bleeding during treatment with aspirin versus apixaban in patients with atrial fibrillation unsuitable for warfarin: the apixaban versus acetylsalicylic acid to prevent stroke in atrial fibrillation patients who have failed or are unsuitable for vitamin K antagonist treatment (AVERROES) trial.
Apixaban reduces stroke with comparable bleeding risks when compared with aspirin in patients with atrial fibrillation who are unsuitable for vitamin k antagonist therapy. This analysis explores patterns of bleeding and defines bleeding risks based on stroke risk with apixaban and aspirin. ⋯ Anatomic sites and predictors of bleeding are similar for apixaban and aspirin in these patients. Higher CHADS2 scores are associated with increasing rates of bleeding and stroke, but the balance between risks and benefits of apixaban compared with aspirin is favorable irrespective of baseline stroke risk.

Randomized Controlled Trial Multicenter Study
Antihypertensive treatment prolongs tissue plasminogen activator door-to-treatment time: secondary analysis of the INSTINCT trial.
Identifying modifiable tissue plasminogen activator treatment delays may improve stroke outcomes. We hypothesized that prethrombolytic antihypertensive treatment (AHT) may prolong door-to-treatment time (DTT). ⋯ Prethrombolytic AHT is associated with modest delays in DTT. This represents a potential target for quality-improvement initiatives. Further research evaluating optimum prethrombolytic hypertension management is warranted.
