Avoid Another Stroke: Take Charge of Your High Blood Pressure

If you’ve had a stroke, it’s important to set goals to lower your risk of having another one — and treating high blood pressure may be the most important one.

High blood pressure makes your heart work harder than it should have to and damages your arteries, according to the American Heart Association. When coupled with a buildup of plaque called atherosclerosis, it can spur even higher blood pressure and cause more harm, possibly leading to another stroke.

About 70% of ischemic stroke survivors have high blood pressure, so most are prescribed blood pressure medicines and lifestyle changes to lower it. Here are some basics that can help you control your high blood pressure and decrease your risk of another stroke.

Take medications as directed

Only one in five new prescriptions are ever filled and of those, only about 50% are taken correctly, according to the Centers for Disease Control and Prevention. Taking the right dose of medicine at the right times each day is essential.

High blood pressure is known as the “silent killer” because it usually has no apparent symptoms, which might make you forget to take medications or refill prescriptions. But it’s important to stay on track. Try simple tips such as setting reminders or enlisting friends or family members to ask if you’ve taken your medicine. Do whatever works for you to help you take your medicine correctly.

If you have trouble affording your prescriptions or are dealing with unpleasant side effects, talk with your health care provider and your pharmacist. Be open with your health care team so you can work together to find a solution. It can take a few tries to find the right medicine, dosage and timing, but getting your high blood pressure under control is worth it.

Eat well and watch the salt

You’ve probably heard these nutrition basics before, but they’re especially important for stroke survivors. Eat plenty of vegetables, fruits and whole grains, and don’t forget the low-fat dairy and poultry, fish, legumes, olive oil and nuts. Following this kind of Mediterranean diet, which limits added sugar and red meat, is reasonable for stroke survivors, according to American Heart Association/ American Stroke Association guidelines.

Salt causes your body to retain water, which increases your blood pressure. Some high blood pressure medications (diuretics) help your body get rid of water. Pay attention to your sodium intake and try to keep it around 2,400 milligrams a day or less. Staying under 1,500 mg can lower blood pressure even more. Read nutrition labels carefully, because most sodium comes from processed food, not the salt shaker. And be sure and limit how much alcohol you drink.

Practice physical activity and lose weight

Losing weight can be a challenge even if you haven’t had had a stroke, but it’s recommended for adults with high blood pressure who are overweight or obese. And while a stroke can limit your physical activities, doing aerobic exercise and strength training can improve your ability to do everyday activities and boost your quality of life. It also helps reduce the risk of heart attack and stroke.

If you can engage in physical activity, aim for three to four sessions of moderate- to vigorous-intensity aerobic exercise per week — about 40 minutes per session. Moderate exercise such as walking briskly or riding an exercise bike should make you break a sweat or noticeably increase your heart rate. For a vigorous activity, try jogging.

If those things are too difficult, remember that any physical activity is better than none. Try meeting with your physical therapist or cardiac rehab professional for an activity regimen that works for you.

You can also check out this series of videos with exercises for survivors. You can do them prone, while sitting or by standing with assistance, depending on the activity.

Talk with your health care provider to determine how best to work toward your weight loss goals.

Stroke Rehabilitation

Making the Best Decisions at Discharge After Stroke

The type of rehabilitation and support systems a survivor receives at discharge can strongly influence health outcomes and recovery. In this, the first part of a two-part series on stroke rehab, we offer guidance for the decision-making process required when it’s time to leave the hospital.

What to Expect from Outpatient Rehab

After stroke, about two-thirds of survivors receive some type of rehabilitation. Outpatient therapy may consist of Several types of therapy. Whether a patient is referred to inpatient or outpatient therapy depends on the level of medical care required.

What to Expect in Stroke Rehab

Following a stroke, about two-thirds of survivors receive some type rehabilitation. In this second of our two-part series, we want to alleviate some of the mystery, fear and anxiety around the inpatient rehab part of the stroke recovery journey.

Stroke & Parts of the Brain

When Stroke Affects the Occipital Lobe

Our occipital lobe, the smallest of the four lobes of the cerebral cortex, controls how we visually interpret our world.

When Stroke Affects the Cerebellum

The cerebellum contains 80 percent of our neurons. Its job seems to be to make things better. We talked with neuroscientist Jeremy Schmahmann about how stroke affects the “little brain.”

When Stroke Affects the Parietal Lobe

The parietal lobe helps us make sense of sensory information, like where our bodies and body parts are in space, our sense of touch, and the part of our vision that deals with the location of objects.

When Stroke Affects the Frontal Lobe

Of the four lobes that make up the cerebral cortex, the frontal lobe is the largest. It plays a huge role in many of the functions that make us human — memory, language, movement, judgment, abstract thinking.

When Stroke Affects the Temporal Lobe

The temporal lobe has several functions, mainly involved with memory, perception and language.

When Stroke Affects the Brain Stem

The brain stem serves as a bridge in the nervous system. It sits at the top of the spinal column in the center of the brain. When a stroke happens there, it can cause a few different deficits and, in the most severe cases, can lead to locked-in syndrome.

When Stroke Affects the Thalamus

The thalamus can be thought of as a "relay station," receiving signals from the brain’s outer regions (cerebral cortex), interpreting them, then sending them to other areas of the brain to complete their job.
