Ischemic stroke, which account for about 87% of all strokes, occurs when a blockage in the blood vessels to the brain causes damage to brain tissue. Immediate treatment may minimize long-term disability and even death from a stroke.

How Are We Performing?

At Massachusetts General Hospital, we track several measures related to ischemic stroke, including:

IV tPA - Arrive by 2 Hour, Treat by 3 Hour

See the percentage of eligible stroke patients who receive tPA treatment (anti-clotting drugs) within 3 hours of the start of stroke symptoms (that is, the time they were last known well).

Door to IV tPA: Percent (%) within 60 Minutes

See the percentage of eligible stroke patients who were treated with tPA within 60 minutes of ED arrival.

Door to IV tPA: Median Time

See the percentage of eligible stroke patients who were treated with tPA within 60 minutes of ED arrival.

Door to CT Scan: Percent (%) within 25 Minutes

See the percentage of patients treated with tPA who received brain imaging within 25 minutes of ED arrival.

Door to CT Scan: Median Time

See the median time in minutes from ED arrival to administration of tPA for ischemic stroke patients.

30-Day Mortality Rates

See the percentage of ischemic stroke patients who died within 30 days of admission to the hospital, and the rates of stroke or death within the 30 days for patients that underwent a Carotid Endarterectomy (CEA) procedure.
