Stroke is a serious disease with serious consequences. However, this pathology never occurs “against the background of complete health.” Most often, the patient’s condition is aggravated by concomitant cardiovascular diseases, cholesterol metabolism disorders, and atherosclerosis. Among the most significant risk factors for brain accidents is high blood pressure (BP).
Untreated arterial hypertension can provoke the occurrence of both. Unfortunately, some time after the disaster, patients recover and forget about taking medications. Elevated levels can provoke repeated brain catastrophes. That is why symptoms of high blood pressure always require medication correction.
Why is high blood pressure dangerous?
A stroke occurs due to thrombosis of the arteries supplying the brain. Nerve cells die due to lack of oxygen and nutrients, and such a catastrophe is called ischemic. If a blood vessel ruptures and hemorrhages into the brain tissue, the stroke is called hemorrhagic.
For rehabilitation after a stroke, our readers recommend Monastic tea. Monastic tea consists exclusively of medicinal herbs, is a completely natural product and does not contain chemicals. Improves the process of restoration of damaged cells in the brain, helps restore speech and hearing functions in the victim, and prevents the occurrence of a recurrent stroke. Doctors' opinion..."
According to statistics, a patient’s history of an ischemic or hemorrhagic catastrophe in combination with risk factors significantly increases the likelihood. And high blood pressure is known to be one of the most significant risk factors.
Why is this happening? Doctors have long found answers to these questions:
- Persistent chronic arterial hypertension has a damaging effect on the arterial wall. In combination with severe atherosclerosis and a large amount of cholesterol deposits, the risk of thrombosis of cerebral vessels increases many times. It is the clots in the arteries that cause the initial symptoms of ischemic disasters.
- High blood pressure in the post-stroke period continues to have a damaging effect on blood vessels. The perfusion of brain tissue suffers, and this significantly slows down recovery and rehabilitation. There is a decrease in the functional activity of intact neurons.
- According to various sources, from 13 to 20% of all strokes are hemorrhagic. They are associated with vascular rupture and hemorrhage. The rupture occurs at weak points in the arterial wall. Often these are aneurysms or arteriovenous malformations. But the main provoking factor can only be high blood pressure. Hypertensive crises are often complicated by stroke intracerebral hematomas.
That is why maintaining blood pressure within normal limits is the basis for the prevention of recurrent strokes, promotes rapid recovery and restoration of lost functions.
When and how to adjust
The concept of “norm” in matters of arterial hypertension among doctors is always unambiguous. The pressure should be within 120-130/80-90 mmHg. Many patients consider higher numbers to be their “working” constant pressure. If you have such a position, then it is fundamentally wrong. Exceeding the limits of the above figures or any permanent increase in indicators should be subject to drug correction.
Separately, it is worth considering the issue of the early post-stroke period. In the acute period of hemorrhagic or ischemic stroke, a very pronounced increase in pressure is quite often observed. This is due to damage to brain neurons. In this case, the reduction should be gradual, since sudden jumps can further aggravate the damage.
Tablet pressure correction after a stroke is prescribed only by a doctor. Doctors generally adhere to the following principles:
- At the initial stages of therapy, blood pressure should be constantly monitored. Patients keep a special diary where they record their readings 3-4 times a day. Based on these data, the doctor can adjust the therapy.
- Normalization of blood pressure should occur gradually. Prescribing large dosages of drugs can cause the blood pressure to be too low. This reduces brain perfusion and slows recovery after a stroke.
- The selection of a treatment regimen is carried out individually. Doctors always take into account symptoms of other concomitant diseases. This should be done to avoid drug interactions.
Sometimes in patients after. It is especially common in bedridden, paralyzed patients in serious condition. What pressure is considered low? The norm implies a lower limit of 90/60 mmHg. If you move beyond these thresholds, you should be alarmed and consult a doctor.
What can cause a decrease in blood pressure after a stroke:
Patient Reminder
Maintaining blood pressure within normal limits helps people recover faster and prevent recurrences. To do this you need:
- Spend more time outdoors, starting with slow walks in green areas. Oxygen and breathing exercises help normalize the functioning of the autonomic nervous system and avoid sudden surges in pressure. Daily walks are the norm for patients after a stroke.
- Following a diet, limiting salty foods. Excessive salt intake contributes to fluid retention in the vascular bed and provokes symptoms of arterial hypertension after a stroke.
- Strict adherence to all medical recommendations. Never adjust treatment regimens or discontinue medications on your own. Normal blood pressure, in your opinion, may be a pathology in the eyes of doctors.
- Constant self-monitoring of blood pressure at home. Write down at what time the increases occurred and what types of activities they were associated with.
Blood pressure control during the post-stroke recovery period is a key point in the prevention of recurrent accidents and other cardiovascular diseases. Constantly taking medications, following a diet and moderate physical activity will help maintain and maintain health.
