Hypertension vascular obstruction precursors are mainly clinical manifestations of atherosclerosis, such as dizziness, headache, chest tightness, chest pain and so on. 1. Atherosclerosis mainly occurs in large and middle arteries, with no obvious symptoms in the early stage; with the narrowing of blood vessels, corresponding ischemic symptoms can appear when different organs are involved, such as dizziness, headache, chest tightness, chest pain, abdominal pain, intractable hypertension, gangrene of the lower limbs and so on. 2. As the blood vessels of the whole body are in the state of high pressure in hypertensive patients, the side walls are subjected to pressure impact, so that the endothelium of blood vessels is damaged. Damaged endothelial cells have pro-coagulant effects:initiating endogenous and exogenous coagulation pathways, promoting platelet activation and inhibiting fibrinolysis. Prolonged hypertension promotes the development of atherosclerosis, resulting in the narrowing of blood vessels, the continued development of which can lead to vascular obstruction. 3. Hypertensive patients with atherosclerosis leading to vascular obstruction. They should pay attention to the fact that they should reduce the intake of oils rich in saturated fatty acids in their daily diet and consume a lot of fruits and vegetables instead. It is recommended to replace refined grains with low glycemic index cereals and whole grains, etc. 4. Lowering blood lipid levels is the basic strategy for treating atherosclerosis. Currently, the most effective lipid-lowering drugs are HMG-CoA reductase inhibitors, i.e. statins can prevent, reduce or even reverse atherosclerosis by inhibiting endogenous cholesterol synthesis and lowering plasma LDL cholesterol levels. Note that the use of drugs need to comply with medical advice, it is recommended to standardize treatment under the guidance of a doctor.
