Introduction to Stroke and the Stroke Care Unit

Several measures can help prevent stroke. It is important to understand personal stroke risk factors and follow the healthcare professional’s recommendations regarding a healthy lifestyle. For a person who has already had a stroke, these measures may help prevent recurrence. After a TIA, they can reduce the likelihood of a future stroke. Follow-up care in hospital and after discharge also plays an important role.

Many stroke-prevention strategies are the same as those used to prevent heart disease. General healthy-lifestyle recommendations include:

1. Home-Based Preventive Measures:

A healthy lifestyle for stroke prevention should include: 

:Control Hypertension- 

Controlling hypertension is one of the most important measures for reducing stroke risk. In patients with a previous stroke, lowering blood pressure may help prevent a subsequent TIA or stroke. Healthy lifestyle changes and medications are often required to manage hypertension.

 : Reduce Foods High in Cholesterol and Fat- 

Reducing dietary cholesterol and fat—particularly saturated and trans fats—may decrease fatty accumulation in the arteries. If dietary changes alone do not adequately control cholesterol, lipid-lowering medication may be required.

: Avoid Smoking

Smoking increases stroke risk in both smokers and nonsmokers exposed to secondhand smoke. Smoking cessation therefore helps reduce the likelihood of stroke.

: Manage Diabetes- 

Control diabetes mellitus. A healthy diet, exercise, and weight loss can help maintain blood glucose within the target range. If lifestyle measures are insufficient, antidiabetic medications may be prescribed.

: Maintain a Healthy Weight- 

Excess weight contributes to other stroke risk factors, including hypertension, cardiovascular disease, and diabetes mellitus.

: Exercise Regularly and Manage Psychological Stress- 

Aerobic exercise reduces stroke risk in several ways: it can lower blood pressure, raise high-density lipoprotein (HDL) cholesterol, and improve overall vascular and cardiac health. It also supports weight loss, diabetes control, and stress reduction. Physical activity should be increased gradually to at least 30 minutes of moderate-intensity activity on most or all days of the week. The American Heart Association recommends 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous aerobic activity each week. Moderate-intensity activities may include walking, jogging, swimming, and cycling.

: Avoid Alcoholic Beverages-  

Heavy alcohol consumption increases the risk of hypertension and both ischemic and hemorrhagic stroke and may interact with the patient’s medications. The source text notes that small or moderate amounts may reduce clotting and possibly lower ischemic-stroke risk; however, the appropriate advice should be determined by a healthcare professional for each individual patient.

: Treat Obstructive Sleep Apnea- 

Obstructive sleep apnea is a sleep disorder in which breathing repeatedly stops for brief periods during sleep. A healthcare professional may recommend a sleep study when symptoms are present. Treatment may include positive airway pressure delivered through a mask to keep the airway open during sleep.

 : Avoid Illicit Drugs- 

Certain illicit drugs, including cocaine and methamphetamine, are established risk factors for TIA and stroke.

: Maintain a Balanced, Healthy Diet- 

Follow a diet rich in fruits and vegetables. Consuming five or more servings of fruit and vegetables daily may reduce stroke risk. A Mediterranean-style diet emphasizing olive oil, fruit, nuts, vegetables, and whole grains may also be beneficial.

2. Preventive Medications

Patients who have previously experienced an ischemic stroke may require medication to reduce the risk of another event. Following a TIA, medication may reduce the risk of a future stroke. These medications include:

 : Antiplatelet Agents- 

Platelets are blood cells involved in clot formation. Antiplatelet agents make platelets less adhesive and less likely to form clots. Aspirin is the most commonly used antiplatelet agent, and the physician may prescribe a dose appropriate for the patient’s condition.

After a TIA or minor stroke, aspirin may be prescribed together with another antiplatelet agent such as clopidogrel (Plavix) for a defined period 

to reduce the risk of recurrent stroke. When aspirin is contraindicated, clopidogrel may be prescribed alone. Ticagrelor (Brilinta) is another antiplatelet medication that may be used for stroke prevention.

: Blood-Thinning Medications (Anticoagulants)- 

These medications reduce blood clotting. Heparin is a rapid-acting anticoagulant that may be used for a short period in hospital.

Warfarin (Jantoven), which has a slower onset of action, may be used for longer-term therapy. Because warfarin is a potent anticoagulant, it must be taken exactly as prescribed, with monitoring for adverse effects. Regular blood testing is also required to assess its anticoagulant effect.

Several newer anticoagulants are available for stroke prevention in high-risk patients, including dabigatran (Pradaxa), rivaroxaban (Xarelto), apixaban (Eliquis), and edoxaban (Savaysa). They act more rapidly than warfarin and generally do not require routine blood tests or frequent medical monitoring. They may also reduce the risk of certain bleeding complications compared with warfarin.

3. Prevention Using Alternative Therapies

There is no herbal cure for stroke; however, some herbs may affect blood clotting, including:

Turmeric, ginger, cayenne pepper, Ginkgo biloba, garlic, and cinnamon.
