If you've had a stroke, preventing a second stroke is a top priority. "The risk of a stroke is tenfold higher in someone who has had a stroke in the past," says Larry B. Goldstein, MD, professor of medicine (neurology) and director of the Duke Stroke Center in Durham, N.C.
Prevention of a second stroke starts by addressing conditions that caused the first stroke, such as atrial fibrillation (an abnormal heart rhythm that can cause blood to clot) or narrowing of a carotid artery in the neck. Treatment is also aimed at other factors that put you at risk, including high blood pressure, diabetes, and high cholesterol. But it takes more than just your doctor's efforts. You also have an important role to play in preventing stroke. It's up to you to make lifestyle changes that can lower your risk.
You should consider these symptoms warning signs and consult your health care provider or call 911 right away:
Sudden weakness or numbness in the face, arm, or leg on one side of the body.
Abrupt loss of vision, strength, coordination, sensation, speech, or the ability to understand speech. These symptoms may become worse over time.
Sudden dimness of vision, especially in one eye.
Sudden loss of balance, possibly accompanied by vomiting, nausea, fever, hiccups, or trouble with swallowing...
A stroke can be a devastating experience. Surviving it can be a powerful motivation to make lasting positive changes in your life. Take charge of your future by following these recommendations.
Prescription for Recurrent Stroke Prevention
Antiplatelet drugs and anticoagulants are medicines that can help reduce the risk of a second ischemic stroke. These medicines interfere with the blood's clotting action so that clots can't form and cause a stroke. Aspirin is one of the most common, most effective, and least expensive types of antiplatelet medication.
There are several types of blood thinners available, and your doctor will choose one based on your medical history, your health conditions, and the potential for side effects. For example, people with a bleeding disorder may not be able to take aspirin.
When you use these medications, it's important to take them as prescribed. Even if you've taken aspirin in the past for pain relief, do not take more than your doctor recommends. Also, ask about potential interactions. For instance, the most commonly used anticoagulant, warfarin, can be affected by other drugs and by foods, such as green leafy vegetables, which are high in vitamin K.
Know Your Numbers: Keep Blood Pressure Low
High blood pressure exerts continuous pressure on the walls of the arteries. If it is left untreated, it damages and weakens your arteries, making them more likely to clog or burst and cause a stroke. Hypertension is the biggest contributing risk factor to stroke.
