Ischemic Stroke


An ischemic stroke occurs when blood is suddenly blocked and cannot flow to your brain. The block is usually caused by a blood clot that gets stuck in a narrow blood vessel. When oxygen cannot get to an area of the brain, tissue in that area may get damaged. Damage to an area of the brain causes loss of body functions controlled by that area. When stroke symptoms last a few minutes to hours and do not cause damage, it is called a transient ischemic attack (TIA). A TIA is a warning sign that you are at risk of soon having a stroke.


Call 911 for any of the following:

  • You have any of the following signs of a stroke:
    • Numbness or drooping on one side of your face
    • Weakness in an arm or leg
    • Confusion or difficulty speaking
    • Dizziness, a severe headache, or vision loss
  • You have a seizure.
  • You feel lightheaded, short of breath, and have chest pain.
  • You cough up blood.
  • You have a severe headache, or loss of balance or coordination.

Seek care immediately if:

  • Your arm or leg feels warm, tender, and painful. It may look swollen and red.
  • You have double vision or vision loss.
  • You have unusual or heavy bleeding.

Contact your healthcare provider or neurologist if:

  • Your blood pressure is higher or lower than you were told it should be.
  • You have questions or concerns about your condition or care.


You may need any of the following:

  • Antiplatelets , such as aspirin, help prevent blood clots. Take your antiplatelet medicine exactly as directed. These medicines make it more likely for you to bleed or bruise. If you are told to take aspirin, do not take acetaminophen or ibuprofen instead.
  • Blood thinners help prevent blood clots. Examples of blood thinners include heparin and warfarin. Clots can cause strokes, heart attacks, and death. The following are general safety guidelines to follow while you are taking a blood thinner:
    • Watch for bleeding and bruising while you take blood thinners. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
    • Tell your dentist and other healthcare providers that you take anticoagulants. Wear a bracelet or necklace that says you take this medicine.
    • Do not start or stop any medicines unless your healthcare provider tells you to. Many medicines cannot be used with blood thinners.
    • Tell your healthcare provider right away if you forget to take the medicine, or if you take too much.
    • Warfarin is a blood thinner that you may need to take. The following are things you should be aware of if you take warfarin.
      • Foods and medicines can affect the amount of warfarin in your blood. Do not make major changes to your diet while you take warfarin. Warfarin works best when you eat about the same amount of vitamin K every day. Vitamin K is found in green leafy vegetables and certain other foods. Ask for more information about what to eat when you are taking warfarin.
      • You will need to see your healthcare provider for follow-up visits when you are on warfarin. You will need regular blood tests. These tests are used to decide how much medicine you need.
  • Thrombolytics help break apart clots. These medicines make it more likely for you to bleed or bruise.
  • Other medicines may be given to treat high cholesterol, high blood pressure, or diabetes. You may also need medicine to decrease pain or prevent seizures.
  • Take your medicine as directed. Call your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Warning signs of a stroke:

The word F.A.S.T. can help you remember and recognize signs of a stroke:

  • F = Face: One side of the face droops.
  • A = Arms: One arm starts to drop when both arms are raised.
  • S = Speech: Speech is slurred or sounds different than usual.
  • T = Time: A person who is having a stroke needs to be seen immediately. A stroke is a medical emergency that needs immediate treatment. Some medicines and treatments work best if given within a few hours of a stroke. Early treatment can decrease the risk of long-term effects of a stroke.

Follow up with your healthcare provider or neurologist as directed:

You may need to come in for regular tests of your brain function. You may also need regular blood tests. Write down your questions so you remember to ask them during your visits.

Go to rehabilitation (rehab) as directed:

Rehab is an important part of treatment. A speech therapist helps you relearn or improve your ability to talk and swallow. You may start slowly and start doing more difficult tasks over time. Physical therapists can help you gain strength and build endurance. Occupational therapists teach you new ways to do daily activities, such as getting dressed. Therapy can help you improve your ability to walk or keep your balance. Your therapy may include tasks or movements you will need to do for everyday activities. An example is being able to raise or lower yourself from a chair.

Prevent another stroke:

  • Do not smoke cigarettes or use illegal drugs. Smoking and drugs increase your risk for a stroke. Nicotine and other chemicals in cigarettes and cigars can also cause lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products. Ask your healthcare provider for information if you need help quitting.
  • Manage health conditions. Take your medicine as directed. Check your blood pressure and blood sugar levels as directed. Keep a record and bring it to your follow-up visits.

  • Eat a variety of healthy foods. Healthy foods include whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Eat at least 5 servings of fruits and vegetables each day. Choose foods that are low in fat, cholesterol, salt, and sugar. Eat foods that are high in potassium, such as potatoes and bananas.
  • Maintain a healthy weight. Ask your healthcare provider how much you should weigh. Ask him to help you create a weight loss plan if you are overweight. Ask about the best exercise plan for you.
  • Limit or do not drink alcohol. Limit alcohol to 2 drinks per day if you are a man. Limit alcohol to 1 drink per day if you are a woman. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
