Patients with blocked blood vessels will directly lead to increased blood pressure. Usually, the factors that cause increased blood pressure are the following 3 aspects, namely peripheral resistance of blood vessels, elasticity of arterial walls, and blood viscosity, and blocked blood vessels will directly lead to the above 3 factors. In normal people, the inner membrane of blood vessels is smooth and fluid, but patients with blocked blood vessels will gradually form atherosclerotic plaques under the inner membrane, resulting in hardening of blood vessels, decreased elasticity of arterial walls, and increased brittleness, thus increasing blood pressure. The atherosclerotic plaque will rupture leading to bleeding, the vascular blockage will worsen, the lumen will narrow and the hemodynamics will increase, which will further aggravate the increase in blood pressure. When the blood vessel is blocked, the viscosity of blood will also increase, thus making the resistance to blood flow increase, and blood pressure will also rise, so the blockage of blood vessel will directly lead to high blood pressure.
