Blood vessels with hypertension above 180 mmHg are at risk of rupture, but there are individual differences. Rupture of blood vessels due to hypertension is due to microvascular aneurysms formed by long-term hypertension. The aneurysm walls are very thin and may rupture when the systolic pressure increases to a certain level. Diabetes or uremia if the condition is not well controlled, the blood vessels will degenerate or atherosclerosis, some patients with systolic blood pressure less than 180mmHg may rupture, some young people due to mood swings, blood pressure can suddenly rise to 180mmHg, or even higher, and there will be no rupture of blood vessels. This is because most young people do not have underlying diseases and have good vascular elasticity. Blood pressure how much blood vessel rupture is related to the health of the blood vessels, the less elastic the blood vessels, the lower the pressure they can withstand, especially diabetes and uremia in the late stages of serious vascular damage, can not withstand too high blood pressure, so control of blood pressure is significant, systolic blood pressure can not exceed 160mmHg, otherwise it is easy to intracranial hemorrhage.
