Stroke due to high blood pressure in cold weather

HanoiThe 41-year-old man was eating rice when he suffered a stroke, which the doctor diagnosed due to high blood pressure in cold weather.

Doctor Ta Duc Thao (Stroke Department, 108 Military Hospital) on February 12 said that the patient had a headache, vomiting, complete left hemiplegia, lethargy, and slow response. elevated blood pressure 200/110 mmHg (average adult blood pressure is less than 120/80 mmHg). The family discovered, brought to the hospital for examination, the CT scan results showed that the patient was bleeding in the brain.

Doctors treated with hemostatic drugs, anti-brain edema. On the 10th day, the patient partially recovered, his consciousness was awake, but the left hemiparesis had not yet recovered.

Dr. Thao said that the main cause of stroke in this patient was undetected and untreated hypertension. In the past time, the severe cold weather in the North is a contributing factor to the increase in the rate of brain bleeding. The reason is that cold weather causes a sudden change in temperature, peripheral blood vessels constrict, bringing blood to the organs and brain, called circulatory centralization, leading to a spike in blood pressure, especially In particular, the pressure in the cerebral blood vessels increases suddenly, causing cerebral hemorrhage.

“Usually, patients with high blood pressure may not have had a brain bleed, but adding the cold weather factor increases the risk of brain bleeding,” the doctor said.

A stroke is a condition in which a part of the brain is suddenly stopped supplying blood due to a ruptured blood vessel (cerebral hemorrhage) or because a blood clot or plaque completely blocks a blood vessel supplying that area of ​​the brain (cerebral infarction). render the patient unconscious or paralyzed.

According to Dr. Thao, high blood pressure is a risk factor for stroke. According to statistics from the Ministry of Health, each year Vietnam records about 200,000 new strokes, 80% of which are people with high blood pressure. Nearly 40% do not know the disease, 69% are not controlled.

The mechanism of disease is when blood pressure increases, especially in cold weather, the force of blood on the artery walls is higher than necessary. Over time, blood vessels are damaged, not elastic anymore. The vessel can rupture when the blood clot presses on, causing bleeding. In particular, when the temperature drops, it also makes the blood easier to clot and stickier, increasing the possibility of blood clots that obstruct blood circulation to the brain, leading to the risk of stroke.

Brain hemorrhage can appear while working, living, or right in sleep or just waking up, unpredictable. Common signs of brain hemorrhage include headache, nausea, vomiting, convulsions, dizziness, ringing in the ears, unsteadiness, blurred vision, stuttering, and loss of mobility or consciousness. If the intervention is delayed, when the patient is in a coma too deeply, the brain is compressed too much, even though it can save life, the recovery ability is very low.

To prevent stroke in cold weather, it is very important to keep the body warm, especially the head and neck area in the cold season. Should sleep in a closed room, always keep enough warmth for the body. It should be noted that a sudden change in temperature can cause heat stroke, so in the morning before getting out of bed, you should have some light movements to warm up your body, adapt to the weather outside, don’t get out of bed. as soon as you wake up. Keep the indoor temperature balanced, get your body used to it, and dress warmly before going out in cold weather. Drink warm water and avoid cold foods. Do not take a late shower as well as do not take a cold shower, using warm water about 37 degrees Celsius is the most suitable.

In addition, patients need to regularly check their health periodically to see if they have high blood pressure; antihypertensive treatment with the right drug, right dose and with periodical monitoring; Be careful when the weather changes.
