The main reason for insufficient blood supply to cardiovascular and cerebrovascular tissues is the narrowing of blood vessels due to atherosclerosis of arteries and blood vessels, which can be improved by taking antihypertensive drugs, lipid-lowering drugs and antiplatelet aggregation drugs. Vascular stenosis is mainly caused by atherosclerosis of blood vessels under the action of high blood pressure, high blood fat and other comprehensive factors. Vascular stenosis affects blood circulation and interferes with the normal blood supply to cardiovascular and cerebral tissues, thus generating the performance of insufficient blood supply. To improve cardiovascular blood supply insufficiency, you can take antihypertensive drugs such as yin’s’p metoprolol, captopril, verapamil, etc.; lipid-lowering drugs, including atorvastatin, benzabephetamine, etc.; anti-platelet adhesion and aggregation, to prevent thrombosis, such as aspirin, clopidogrel, etc., to inhibit thrombosis to reduce the degree of stenosis of the blood vessels. Drugs do not exist in the absolute safest and most effective, need to be standardized under the guidance of a doctor to avoid abuse of drugs, such as the emergence of adverse reactions to consult a doctor in a timely manner.
