Many national and international professional organizations including the American Stroke Association have suggested general stroke recommendations based on the currently available evidence to monitor the time from emergency room arrival until blood flow is restored to the blocked brain artery in order to reduce the risk of severe disability and death. However, data demonstrating the urgent need for continued research on treatment of ischemic stroke is limited.
A limitation of this study is that the hospital already had extensive experience with immediate angiography, so findings may differ at hospitals or care centers with less angiography expertise or experience. Another limitation is that the results of the study were not monitored by an external review group.

According to the American Heart Association’s Heart Disease and Stroke Statistics — 2021 Update, when considered separately from other cardiovascular disease, stroke ranks No. 5 among all causes of death in the U.S., causing 147,810 deaths in 2018. Stroke occurs when a blood vessel to or in the brain either becomes blocked or bursts, preventing blood and oxygen from reaching all of the brain. Treatment to quickly restore blood flow to the brain is essential to improve outcomes and survival.
