This information was assigned by Assoc. Prof. Dr. Nguyen Huy Thang, Chairman of Ho Chi Minh City Association, Head of the Department of Cerebral Vascular disease-People's Hospital 115 (Ho Chi Minh City), shared recently, which is being concerned by many people.
Control blood pressure to prevent stroke when the weather changes seasons
According to Dr. Thang, every time the weather changes seasons, he often receives many messages from patients and relativesstroke, especially from November to January every year.The hospitalized patients are mainly male, have the same situation or recur, high blood pressure but do not use drugs, often use alcohol and finally brain hemorrhage.This is considered a very severe stroke with a mortality rate that can be up to 50%.
Dr. Thang said that medical studies show that the weather may directly affect the risk of stroke.Factors such as the weather is too cold, too hot or especially when the wet climate can activate the stroke.
When the weather is hot and humid, the body is dehydrated, easy to form blood thrombosis in the blood vessels, especially in the vein system.This risk increases as we exposed to the direct sunlight for a long time or when the body temperature exceeds 40 ° C.
On the contrary, when the weather is cold, we often do not drink enough water, leading to a water shortage, which also increases the ability to form thrombosis.In addition, the weather is too hot or too cold can cause excessive elasticity of blood vessels, leading to hypertension and increase the activity of the heart.
In particular, for elderly people or patients with background diseases such as hypertension, this condition becomes more and more dangerous if not well controlled.
Many studies have shown that, when the weather changes, the body can adapt to blood pressure, especially at the time of changing seasons.This is the cause of high blood pressure, especially in patients with hypertension, those who do not take blood pressure regularly.With cerebral hemorrhage, the culprit of most cases is high blood pressure (more than 90%).
To prevent stroke, experts recommend that systolic blood pressure should be maintained below 130 mmHg at all ages.According to research, for patients who have had a stroke, if the systolic blood pressure is reduced to less than 120 mmHg, the prevention effectiveness reaches the optimal level.
The current blood pressure control is very easy thanks to the development of combined drugs, such as Perindopril, Telmisartan, and Valsartan in combination with Amlodipine to increase efficiency and ease of use, thereby improving compliance with compliance.treatment.
When blood pressure is stable at the lowest possible level, the risk of cerebral hemorrhage will greatly decrease.According to the study, only 10 mmHg systolic blood pressure decreased, the ratio of cerebral hemorrhage has decreased by 64%.Therefore, maintaining blood pressure at the target level is extremely important to prevent dangerous complications.
In fact, at the 115 People's Hospital, in the last months of the year and the beginning of the following year, the proportion of patients hospitalized due to cerebral hemorrhage related to hypertension often increased significantly.
Dr. Thang also noted at the end of the year, patients need to strictly control the background diseases, especially hypertension, because blood pressure can increase suddenly when the weather changes seasons;older people;Obesity and many background diseases are subjects at high risk of stroke.Besides, at the end of the year, there are many festivals, parties, excessive use of alcohol can cause rapidly increasing blood pressure.Therefore, minimize the use of alcohol on these occasions.
A useful advice for patients with hypertension is to store blood pressure controls everywhere, such as in wallets, on the desk or even at home of relatives, friends ... to avoidForgot to take medicine.
Note, more than 70% of stroke patients can be prevented if they take proper preventive medicine before.
