Low-dose ticagrelor combined with aspirin for preventing early neurological deterioration in patients with high-risk non-disabling ischemic cerebrovascular events: a multicenter, prospective, randomized, open-label, clinical trial.

Why it matters

Clopidogrel's efficacy is limited by CYP2C19 polymorphisms common in Asian populations, and rapid genotyping is often unavailable. This trial offers a practical alternative that avoids genotyping and reduces early deterioration, a key predictor of poor stroke outcomes.
