Why should hypertensive patients be alert to cerebral hemorrhage? Why is hypertension easy to cause cerebral hemorrhage? Hypertension and cerebral hemorrhage are closely related and inseparable. The onset of cerebral hemorrhage is based on the original hypertensive lesions, and the blood pressure is further suddenly increased, so it is called high blood pressure cerebral hemorrhage.
However, it is generally believed that the increase of blood pressure alone is not enough to cause blood overflow and bleeding. It has been observed that normal human cerebral arteries can withstand a pressure of 200 kPa (1500 mmHg) without blood vessel rupture. So atherosclerosis is an important pathological basis of cerebral hemorrhage. More than 80% of cerebral hemorrhage is caused by hypertension and arteriosclerosis, so it is also called Hypertensive Cerebral Arteriosclerotic Cerebral hemorrhage.
On the one hand, hypertension is not only one of the causes of atherosclerosis, but also can accelerate the process of atherosclerosis. The sclerotic vascular wall becomes fragile and easy to rupture; meanwhile, the sclerotic vascular wall becomes less elastic and easy to form aneurysm, which lays the pathological foundation for vascular rupture. On the other hand, long-term chronic hypertension can lead to some special pathological changes in cerebral arteries, such as the formation of small aneurysms (rarely found in cerebral arteries of patients without hypertension), resulting in fat hyaline degeneration of small arteries, and the formation of dissecting aneurysms in the wall of small arteries, which can rupture and bleed when the blood pressure rises suddenly.
It can be seen that there are two pathological bases for cerebral hemorrhage in patients with hypertension. One is cerebral atherosclerosis, and the other is special pathological changes of cerebral vessels such as microaneurysms and dissecting aneurysms. It is like burying two 'time bombs' of cerebral hemorrhage. Once blood pressure rises suddenly, cerebral hemorrhage is easy to occur. This also shows that hypertension is the main cause of cerebral hemorrhage, cerebral hemorrhage is the most serious consequence or complication of hypertension. So people think that hypertension is the most dangerous factor of cerebral hemorrhage. Therefore, active and effective prevention and treatment of hypertension and hypertension is an important measure to prevent cerebral hemorrhage.
After reading the above contents, we should have some understanding of why hypertensive patients should be vigilant against cerebral hemorrhage. Today, we will introduce more topics about hypertension treatment and health care. We will continue to introduce them in the following articles. Welcome to check. I wish you a happy life!
