How high blood pressure will cause cerebral hemorrhage?

Cerebral hemorrhage is a common physical disease in real life, and the main cause of cerebral hemorrhage is blood pressure. When the human blood pressure reaches a certain number, it will easily lead to rupture of blood vessels in the brain, which can easily cause bleeding in the brain. When the human body is angry, it will easily lead to high blood pressure, but there is no fixed amount, so prevention is needed in advance.

How high blood pressure can cause cerebral hemorrhage

Common causes of cerebral hemorrhage are hypertension, arteriosclerosis, hyperlipidemia, etc. These factors will cause decreased vascular elasticity and high blood pressure. When you are excited or angry, your blood pressure suddenly rises, leading to cerebral hemorrhage and hemiplegia. Dietary treatment is crucial during recovery, and you must strictly follow the diet requirements.

Everyone's situation is different, so it is best to check in time. If you have high blood pressure, you need to take active medication to control it. It is recommended to use long-acting preparations such as telmisartan, which require fewer doses and have a stable antihypertensive effect. Pay attention to the combination of work and rest, maintain adequate sleep, participate in work within your ability, physical labor and physical exercise.

Causes

The underlying cause is high blood pressure, which usually occurs during activity and emotional excitement.

Most scholars believe that long-term hypertension can cause hyaline degeneration of cerebral arteries, which first causes the subintimal matrix to swell, lipids to precipitate under the intima, and an unstructured substance to form between the intima and the internal elastic layer, which reduces elasticity and increases fragility. The blood vessel wall loses tension and undergoes fibrinous necrosis, causing the local artery to bulge into a spindle or spherical shape under the impact of blood pressure, namely a miliary aneurysm. Blood can also invade the vessel wall to form a dissecting aneurysm. When blood pressure rises suddenly, the aneurysm ruptures and causes bleeding.

In addition, hypertension can also cause spasm of cerebral arterioles, leading to ischemia, hypoxia, necrosis of distal brain tissue and bleeding. In addition, the walls of the cerebral arteries are weak, with few middle-layer muscle cells and adventitial connective tissue, and no external elastic layer, which may lead to more hypertensive cerebral hemorrhage than other visceral bleeding.

Clinical manifestations

Hypertensive cerebral hemorrhage often occurs during activities, excitement, or straining to defecate. It has an acute onset and often reaches its peak within minutes or hours. The clinical manifestations vary depending on factors such as the site of bleeding, amount of bleeding, and general condition. The disease usually presents with sudden severe headache, nausea, vomiting, and is often accompanied by agitation, drowsiness or coma. Hemiplegia and pupil changes occur on the opposite side of the hematoma. In the early stage, the pupils on both sides shrink. When the hematoma expands and cerebral edema worsens, intracranial pressure increases, causing dilated pupils on the hematoma side and other brain herniation crises, respiratory disorders, slow pulse, and increased blood pressure. It then turns into central failure.

examine

Head CT or MRI scan can clearly identify the bleeding site, amount of bleeding, and edema of the brain tissue around the bleeding.

diagnosis

Middle-aged and elderly patients with hypertension may suddenly develop the disease when they are active or emotionally excited, and quickly develop symptoms of focal neurological deficits such as hemiplegia and aphasia, as well as severe headache, vomiting, and impaired consciousness. This often highly suggests the possibility of cerebral hemorrhage, which can be confirmed by CT examination.
