The main measures to prevent blood vessel blockage include controlling risk factors, smoking cessation, rational use of medication and psychological adjustment. 1. Control risk factors: Dietary control (mainly low-salt, low-fat diet) or appropriate exercise can prevent blood vessel blockage. 2. Smoking cessation: Smoking causes blood vessel damage. Strict cessation of smoking and minimizing exposure to second-hand smoke can prevent vascular blockage. 3. Reasonable application of drugs: According to the individual situation, the application of antiplatelet drugs (such as aspirin, clopidogrel, etc.), lipid-lowering drugs (such as atorvastatin, pravastatin, etc.), etc., can also help to prevent blood vessel blockage. 4. Psychological adjustment: long-term mental tension may cause persistent spasm of blood vessels, hardening of blood vessels, and even lead to damage of blood vessel walls. If you have too much pressure in your work life for a long time, you should make psychological adjustment in time to ensure your physical and mental health. If you have or suspect that you have a blood vessel blockage, you should go to the hospital in time and follow the doctor’s instructions for treatment or prevention.
