A stroke occurs when the supply of blood to the brain is blocked, so the brain does not get the oxygen and essential nutrients that it needs. There are three types of stroke: ischemic stroke (caused by a blocked blood vessel), hemorrhagic stroke (caused by a burst blood vessel in the brain) and transient ischemic attack (TIA), also known as a warning stroke.
A stroke is a medical emergency that requires immediate attention, as rapid diagnosis and effective treatment can reduce the chance of negative complications and brain damage. Warning signs of a stroke include: sudden blurred or altered vision, weakness or numbness (usually on one side), difficulty speaking or understanding speech, dizziness and imbalance. It is important to recognize stroke signs early, call 911 and seek emergency treatment within three hours of the onset of symptoms. Learn more about stroke signs and symptoms.
The graphs below show Lexington Medical Center’s performance in following best practices (evidence-based processes of care) and achieving the best results when treating stroke patients.
A column with N/A indicates one of the following: we did not have enough eligible patients to report on that measure; CMS held the data for one or more quarters; results were unavailable for the reporting period; no cases met the criteria for the measure; or results could not be calculated for the reporting period.
Thrombolytic therapies are important clot-busting medications used to treat ischemic stroke. Tissue plasminogen activator (t-PA) is an example of a powerful thrombolytic therapy that dissolves blood clots that cause strokes. This medicine is most effective when given to a patient within three hours after stroke symptoms begin. It may not be an appropriate therapy for all ischemic stroke patients. This chart shows the percent of ischemic stroke patients who went to the emergency department within two hours and received t-PA within three hours after stroke symptoms started.
