According to the National Institute of Neurological Disorders and Stroke (NINDS) trial, patients treated with tPA within three hours of stroke onset were 30% more likely to experience minimal or no disability. This established the crucial time-sensitive nature of stroke treatment and is a core reason for the strict guidelines surrounding the question, “Why no tPA after 3 hours?”

For every minute an ischemic stroke goes untreated, nearly 2 million brain cells die. This fact underscores the extreme urgency required when considering treatment options like tissue plasminogen activator (tPA), making the question of **how soon can you use tPA?** critically important.
