What is a stroke?

A stroke occurs when a blood vessel in the brain is blocked or bursts. Without blood and the oxygen it carries, part of the brain starts to die. The part of the body controlled by the damaged area of the brain can't work properly.

Can you prevent a stroke?

After you have had a stroke, you are at risk for having another one. While you’re in the hospital we can help you avoid a second stroke as well as complications that can develop. Once home you can make some important lifestyle changes to can reduce your risk of stroke and improve your overall health. Learn more about stroke.

How are we doing at providing the best care for patients having a Stroke?

The Comprehensive Stroke Center monitors rates for the following:

Additional publicly reported data can be found on the American Heart Association’s public reporting website:

The Comprehensive Stroke Center at Hartford Hospital monitors complications related to several interventions for patients with acute ischemic stroke. Of the patients at Hartford Hospital treated by IV with the clot-dissolver tPA in FY2021, no patients had complications from receiving IV tPA, compared to the national average complication rate of 6 percent.

The preferred goal for the rate of complications after carotid endarterectomies (CEA) and carotid arterial stenting (CAS) is to have an aggregate complication rate of less than six percent.

  • For 2020, the aggregate complication rate was only 3.4%.

Diagnostic (cerebral) catheter angiography is a common procedure to evaluate the blood vessels in the brain and neck. It is used to determine if any of the blood vessels are narrowed due to plaque or to see if the patient has other blood vessel abnormalities like an aneurysm or AVM. The preferred goal is to have a peri-procedure stroke and death rate less than one percent.

  • For FY2021, the peri-procedure stroke or death rate for diagnostic (cerebral) catheter angiography was only 0.3%.
  • Additionally, it is preferred to have a less than 2% aggregate serious complication rate. For FY2021, the aggregate serious complication rate was only 0.3%.

Timely Stroke Care

Administration of powerful clot busting medications to carefully screened and eligible patients has been shown to be beneficial to patients with acute ischemic stroke by improving their long term outcome. Many studies have confirmed the benefit of giving this medicine to break up blood clots to patients within 3 hours of symptom onset.

Additional blood clots can create complications over the length of the hospital stay or even after discharge. Medications like aspirin, clopidogrel or aspirin with dipyridamole can prevent additional blood clots from forming and should be given within 2 days of arriving at the hospital.

It is important to provide protection from forming clots anywhere in the body after stroke. Up to a third of patients who have moderately severe strokes can develop deep vein thrombosis which can interrupt their rehabilitation and delay recovery. It is most important to protect against this to improve outcome.

Effective Stroke Care

After having a stroke, patients should receive a prescription to continue the medications started at the hospital. Antithrombotic medications, either antiplatelets like aspirin or anticoagulants like warfarin, have been shown to reduce complications after stroke, stroke recurrence and even death. It is important to take your medications as prescribed.

Some patients may have irregular heartbeats like atrial fibrillation or atrial flutter. These patients need specific anticoagulants to manage this important risk factor for stroke. A prescription for this medication should be given at discharge. It is very important to take this medication as prescribed.

Elevated blood lipid levels or cholesterol is a well-documented risk factor for stroke and heart disease. Patients that have atherosclerosis or plaque in their blood vessels or have an LDL greater than 100 mg/dl should be given a prescription for a statin or cholesterol lowering medication at discharge. Taking this medication as prescribed can help prevent a stroke or heart attack.

After stroke, patients and families should receive education about the event (e.g. cause, treatment, and risk factors), their medications and lifestyle changes to prevent another stroke. Patients should be given information on the warning signs and symptoms of a stroke and know to call 911 if they happen again. Information about any follow up appointments should be given to the patient in writing.

Stroke rehabilitation should begin as soon as possible after stroke. A priority of care should be to evaluate what type of rehabilitation the patient needs to enhance their mobility and self-care. The primary goal of rehabilitation is to prevent complications, minimize impairments, and maximize function.
